About BORSIGMembrane Technology



Today membrane-based separation processes are state-of-the-

art and in some areas this technology has become the leading

process solution. This was made possible by the development

and continuous improvement of efficient and selective polymer

membranes that ensure the thermal, chemical and mechanical

stability necessary for industrial use. Integrating the membranes

into suitable module designs ensure reliable and safe operation.

Membranes are used in many applications in the chemical,

petrochemical and oil/gas industries where liquid or gaseous

mixtures containing hydrocarbons must be treated. This can

serve recycling, emission protection or other operational re-

quirements.

One milestone on this way was the successful implementation

of the gaspermeation process for selectively separating orga-

nic vapours from exhaust air, especially the treatment of

vapours released during the distribution and storage of highly

volatile hydrocarbons.

Accompanied by related environmental protection legislation in

the field of gasoline, a large number of membrane systems has

been installed and successfully operated since 1988, making

membrane technology today a leading technology in the field of

industrial gasoline vapour recovery.

Based on this experience, further gaspermeation applications

were successfully implemented in recent years, for example, in

the olefin industry. Today hundreds of industry-scale plants

using BORSIG technology are successfully in operation.

Besides gaspermeation BORSIG Membrane Technology

entered a new challenging technology - the treatment of liquid

hydrocarbons streams by the innovative organophilic nano-

filtration process.

For all these applications BORSIG Membrane Technology offers

membranes and module types. Together with our partners and

within the framework of R&D programmes, we are pursuing

dedicated development efforts in order to continue offering our

customers innovative and cost saving solutions in the future.

Membrane Technology



Emission Control

Volatile Organic Compounds (VOC), defined as a large family of

hydrocarbons with high volatility, occur naturally and are produced in

many industrial processes. In a wide range of industrial applications,

e.g. such as oil & gas industry, chemical industry and petrochemical

industry the use of VOC leads to substantial emissions mainly caused

by evaporation, displacement and purge procedures.

These emissions of volatile organic compounds (VOC) can cause

significant health risks, e.g. they are toxic and carcinogenic.

Additionally they are known as precursor substances for ozone gas,

causing summer smog and thereby contributing to global warming. In

order to protect man and his environment, suitable measures must

hence be taken in order to minimise the resultant emissions.

The use, storage and distribution of solvents and petroleum products

have been identified as the most significant sources for VOC

emissions. Displacement and evaporation processes affect the

release of organic vapours, which are in most cases mixed with air or

other permanent gas. Typical products are

• Solvents

• All kind of gasoline

• Additives

• Diesel, jet fuel

• Alcohols

• Bio fuels

• Crude oil

Worldwide corresponding regulations and emissions laws are imple-

mented to drastically minimise the VOC emissions by the reduction of

VOC consumption and by the installation of emission control systems.

Parallel the industrial operators also focus on these topics to expresstheir ecologically oriented production philosophy.

4



Very often the installation of emission control systems goes

along with economic benefits, e.g. when installing vapour re-

covery units to recover or liquefy the VOC vapours for reuse.

The recovered product value or other associated effects can

affect the profitability and return on investment (ROI). One

example is the tax-refund, which will be granted in some coun-

tries, when the vapours of already taxed products are recovered

and returned into the distribution chain.

BORSIG Membrane Technology offers emission control solu-

tions with maximum recovery rates of up to 99.9% and thereby

enables compliance with all customary emission standards

worldwide whilst also fulfilling the highest quality, safety and

reliability demands.

BORSIG Membrane Technology's portfolio in the field of

emissions protection includes:

• BORSIG Vapour Recovery Unit (VRU)VOC control for tank farms, marine loading and refineries

• BORSIG Carbon Retrofit Unit (CRU)Retrofit of existing active carbon based recovery system

• BORSIG Vent Recovery System (VRS)Product loss reduction at retail stations

Emission Control



VOC control for tank farms, marine loading and refineries

The Application

During storage and distribution of petroleum products large

streams of vapours are released by evaporation and displace-

ment procedures, e.g. by truck-, railcar- or ship loading applica-

tions. According to the common emission legislations and tech-nical guidelines these vapours must be treated preferably in

vapour recovery units. Typical products include:

• Gasoline (all grades)

• ETBE, MTBE, all kind of additives

• Diesel, jet fuel

• Intermediate products, e.g. reformate, naphtha etc.

• Ethanol, methanol

• Chemicals, solvents

Due to the high volatility and therefore high concentration of the

vapours a substantial product loss is affected and also corre-

sponding strict emission limits have been defined to avoid theemission of these harmful substances, e.g.

• European Directive 94/EC/63

• German TA-Luft and BImSchG

• Swiss LRV

• US EPA

Modern vapour recovery units must fulfil all these latest require-

ments as well as further options to allow a flexible and most eco-

nomical operation:

• Fulfil highest safety demands to process explosive vapours• Recovery of pure product vapours but also of mixed products

vapours

• Considering the pre-loading of vessels and railcars

• Treatment of conventional gasoline vapours

• Compatibility with new gasoline specifications,

e.g. Ethanol 85, bio fuels

• Highest flexibility regarding future expansion of customer’s

product portfolio or changing specifications

The BORSIG Solution

The BORSIG Vapour Recovery Unit (VRU) is based on a combination of

absorption or condensation and membrane separation. Main equipment

are liquid ring compressor, scrubber, membrane separation stage and

vacuum pump. The BORSIG VRU process enables an effective treatment

of the vapours meeting the required emission level.

The vapour/air mixture is taken into the VRU by the liquid ring compres-

sor and is mixed with the membrane recycle stream. The compressor

compresses the mixture to the required discharge pressure using a part

of the absorbent stream as liquid hydrocarbon seal that creates a non-

contact seal ring and removes the heat of compression from the gas

stream. The compressed gas is discharged together with the ring liquid

into the absorption column, where vapours get into contact with the exter-

nal absorbent flow and the liquefaction of the vapours is effected by con-

densation and absorption effects. The non-liquefied vapour stream leaves

the column at the top and enters the membrane separation modules.

Supported by the vacuum pump the membrane stage enables a final

cleaning of the vapour stream and the separated enriched hydrocarbon

vapours are recycled to the compressor inlet, which enables an inherentsafety principle by enrichment of the VRU inlet stream. Further vapour

cleaning can also be achieved by additional polishing stages.

BORSIG VRU s are equipped with high quality machinery and materials

only. The combination with most reliable instrumentation and latest state-

of-the-art control systems makes it suitable for all applications and

products.

Advantages & Benefits

• Most compact and modular design

• Unique inherent safety principle• High efficiency of recovery

• Customised to meet individual applications

• Considering customer’s codes & standards

• Flexible and safe for all products

• Flexible for emission changes due to modular process design

• Low maintenance due to machinery and material selection

(e.g. use of stainless steel)

• Highest reliability due to high quality equipment and control

• Self-in-taking principle enables minimised costs for customer’s

vapour piping

Emission ControlBORSIG Carbon Retrofit Unit

Retrofit of existing active carbon based recovery system

The Application

In existing vapour recovery units based on active carbon adsorption technology the adsorbers are designed for a

maximum mass flow of hydrocarbons before being desorbed again. Practical experience has shown that operators

are facing frequently the following difficulties:

• Customer needs more capacity, e.g. due to increased transshipment• The performance of the existing unit is not efficient enough to meet the required emission level

• New product vapours have negative impact on the active carbon or cannot be adsorbed and must be separated

before entering the adsorbers

Safety risks related to potential dangerous exothermic reactions shall be prevented.

The BORSIG Solution

The Carbon Retrofit Unit significantly reduces the hydrocarbon concentration and mass flow entering the adsor-

bers. The separated enriched stream is bypassing the adsorbers and directly entering the existing absorption

system (scrubber). This enables adsorber performance increase and debottlenecking.

The Carbon Retrofit Unit is installed upstream the existing active carbon system. The vapour stream is separated

by the membrane unit into two streams. The stream passing through the membrane material is highly enriched with

hydrocarbons and is given directly into the existing scrubber part of the carbon unit, where the hydrocarbons areliquefied. The light stream is entering the existing adsorbers. The integration of the Carbon Retrofit Unit is easy

and cost effective with only minor modifications of the existing active-carbon-based vapour recovery unit. The retro-

fit system mainly consists of the membrane unit, a vacuum pump and an optional blower.

Advantages and Benefits

• Tremendous reduction of hydrocarbon mass flow to the carbon beds

• Increased safety of the carbon VRU due to the reduction of exothermic reactions in the carbon beds

• Substantial increase of the capacity of the retrofitted system

• Increased efficiency and lower emission level

• Pre-assembled skid-mounted design

• Easy implementation

• Low maintenance• Reduced specific power consumption

Product loss reduction at retail stations

The Application

On car filling stations three main sources for VOC emissions are

identified:

• Emissions caused by storage tank filling Typically these emissions can be minimised by so-called

“Stage I” measures, by balancing the vapours released

during the filling between the underground storage tank and

the filling truck.

• Emissions caused by car tank filling The emissions caused by released vapours from car tank

can be reduced by a conventional “Stage II” vapour return to

the storage tank enabled by vapour suction integrated in

the filling nozzle. Sometimes a limited efficiency of vapour

collection affects the suction of air into the storage tank and

therefore leads to further evaporation of the storage product.

• Storage Tank Breathing Temperature affected breathing and vaporisation in the

storage tank leads to increased tank pressure and therefore

to vent stack emissions to the atmosphere.

Emission ControlBORSIG Vent Recovery System

10



Nowadays more and more local regulations require the control of the entire sea-

ling of car filling stations and the reduction of corresponding leakage losses,

which can cause a product loss (wet stock loss) of up to 0,5% of the car filling

stations throughput and sometimes more. Furthermore these losses have an

impact on our environment as well as on the safety in operating car filling

stations, while hazardous products and the vapours are handled and emitted.

The BORSIG Solution

BORSIG Membrane Technology developed an innovative enhanced add-on

system enabling the increase of the vapour return ratio from the car nozzle to

the storage tank for more efficient vapour collection. The BORSIG VRS is con-

nected to the vent stack to treat the vented air/gasoline vapours. Proven mem-

brane technology generates two streams and selectively separates the air from

the hydrocarbon molecules. The valuable gasoline fraction is returned to the sto-

rage to keep the gas phase saturated and even to liquefy the gasoline vapours

when the due point is reached. The cleaned air is released to the atmosphere.

Advantages and Benefits

• Proven reduction of wet stock losses by 95%, measured by third party• Increased safety of car filling stations

• Better prospects of obtaining planning permission from the authorities

and improved neighbourhood acceptance for filling stations

• Reduced exposure of customers to hydrocarbon vapours during car fuelling.

• Substantial pay back related to the yearly gasoline throughput

• Improved marketing image of the operator

• Elimination of direct stack emission

• Monitoring of the car filling station tightness and function

Product Recovery

Product recovery systems must meet with evermore demanding efficiency

requirements. Economic efficiency, productivity, improved sustainability of

technological processes, as well as optimum utilisation of our resources are

key challenges in this for the industry.

BORSIG Membrane Technology offers optimum solutions here which helps

minimising losses, to recover valuable raw materials or products from

exhaust air or process gas flows and their recycling into the production pro-

cess and therefore enables:

- Recovery of valuable feedstock and product

- Significant reduction of waste and flare gas capacities

Important products and applications include:

• Ethylene monomer from polyethylene (HDPE, LDPE, etc.), EO or VAM

productions

• Propylene monomer from polypropylene production

• Solvent (Butane, Hexane etc.) from slurry-type polymer production

processes• Vinyl chloride monomer (VCM) from PVC production

• Aromatics (Benzene, Toluene, Xylene etc.) from production and storage

• MTBE, ETBE

• Fluoro & Chloro Hydrocarbons from any related processes

• Methanol, Ethanol

• Bio-Fuels from production & storage

Our products include:

BORSIG Ethylene Recovery Unit Ethylene monomer recovery for polyethylene (PE), ethylene oxide (EO) pro-

duction

BORSIG Propylene Recovery Unit Propylene monomer recovery for polypropylene (PP) production

BORSIG Hydrocarbon Recovery Unit Recovery of valuable hydrocarbon products

13

Product RecoveryBORSIG Ethylene Recovery Unit

Ethylene recovery for production of polyethylene (PE) and

production of ethylene oxide (EO) and vinyl acetate mono-

mer (VAM)

The Application

During the production of polyethylene (PE) one typical process

step is the degassing of PE powder and downstream pressurecondensation to condensate hydrocarbons. The residual purge

gas stream is still rich on non-condensable hydrocarbons and

monomer. To prevent enrichment of inert gas a side stream is

typically sent to the flare and also effects a loss of monomer and

hydrocarbons.

Similar purge gas streams can be identified in vinyl acetate

monomer (VAM) and ethylene oxide (EO) processes. For exam-

ple the inert gas Argon must be purged out of the process to

prevent enrichment. Furthermore internal distillation overhead

vents and other reactor purges can be treated.

All these procedure effect- substantial loss of ethylene monomer and of other solvents

- increased flare gas streams and therefore secondary

emissions to the atmosphere

The BORSIG Solution

The BORSIG Ethylene Recovery technology is an easy add-on

system and can be considered in existing and new process

installations. The purge gas stream, typically pressurized and

containing the ethylene monomer and disturbing inert gas, is fed

into the membrane system, while the permeate side of the mem-

brane separation stage is fed back to the existing process gas

compressor’s suction side. By means of the resulting pressuredifference and the hydrocarbon selective membrane material,

the purge gas stream is separated into the inert gas enriched off

gas and the recycled ethylene-rich permeate stream. Typically

no other equipment or machinery is required, which results in a

very simple and reliable process solution.


• Easy installation in new plants and easy retrofit of existing

systems

• Easiest solution – Key equipment membrane separator only

• Quick installation and easy implementation by skid-mounted

modular design• Very short payback period

• Low maintenance

• Safe and reliable operation

• Tailor-made design to meet customer’s codes and

specifications



Product RecoveryBORSIG Propylene Recovery Unit

Propylene recovery for production of polypropylene (PP)

The Application

During the production of polypropylene (PP) one typical process

step is the degassing of PP resin in the resin bin in order to

purge out non-reacted propylene monomer. Typically nitrogen is

used and continuous purge streams containing substantial con-tent of monomer have to processed to minimise the loss of pro-

fit and the required flare gas capacities:

- Substantial loss of propylene monomer

- Increased flare gas streams and therefore secondary

emissions to the atmosphere

The BORSIG Solution

The BORSIG Propylene Recovery technology is an easy add-on

system and can be considered in existing and new process

installations. The purge gas stream compressed and condensed

in the downstream condenser stage, which might be cooled withcooling agent or liquid propylene. For some PP production

licenses an additional dryer system must be installed prior to

condensation. After separating the condensate the remaining

purge gas is fed into the membrane system, while the per-

meate side of the membrane separation stage is fed back to

compressor’s suction side. By means of the resulting pressure

difference and the hydrocarbon selective membrane material,

the purge gas stream is separated into the purified nitrogen

stream and the recycled propylene-rich permeate stream. A

small part of the separated stream is sent to the flare to prevent

accumulation of lighter components.

The process system consists beside the required membranestage, mainly of compressor and condensation unit, fully de-

signed as package unit with dedicated PLC. Sometimes dryers

and transfer liquid pumps are installed to meet specific client’s

requirements.

• Short payback periods in order of 1-3 years

• Safe operation, high reliability, low maintenance

• Tailor-made design to specific plant’s conditions and local

Product RecoveryBORSIG Hydrocarbon Recovery Unit

Recovery of valuable hydrocarbon products

The Application

In many petrochemical/chemical productions process streams

are generated containing significant amounts of hydrocarbons,

such as solvents, alcohols, aromatics etc. Typically these hydro-

carbons are mixed in inert gas streams and must be treated inorder to meet following typical targets:

- to meet off-gas conditions according to emission legislations

- to recover the valuable hydrocarbon content and therefore

minimise the loss of product and profit

- to meet the inlet conditions of any downstream process steps

and systems

The BORSIG Solution

The BORSIG Hydrocarbon Recovery technology is a portfolio of

specially developed and customised process solution to meet

the targets. Typically the membrane separation is combined withother unit operations, such as absorption, condensation, extrac-

tion etc. These hybrid processes are very efficient and enable

the customer to operate his process with highest economically

and ecologically efficiency.

A typical application is the powder degassing in slurry-type PE

plants. Polymer is flashed and stripped with hot nitrogen and the

released purge gas existing of nitrogen and solvents like buta-

ne, pentane or hexane can be processed by a sophisticated

BORSIG Hydrocarbon Recovery process.

The liquefied solvent and the nitrogen can be provided for re-

use with highest purity.


• Flexible system for multiple components handling

• Highest product purities

• Stand-alone solution possible

• Moderate pressures and temperatures applied for required

condensation

• Safe operation, high reliability, low maintenance

• Modular design to meet specific plant’s conditions and local

regulations

• Quick installation and easy implementation by package unit

design

• Feasibility for adoption to existing plants (retrofit design)

BORSIG Membrane Technology offers the possibility to treat

gas flows in oil and gas production applications. The aim is to

condition raw gas flows or to improve product quality to comply

with customer’s gas specifications, pipeline specifications or

calorific-value requirements.

The required gas quality is typically specified by defining

methane content, pressure dew points, calorific values or a mini-

mum methane number. These quality parameters are typically

determined by the share of higher hydrocarbons (C3+), CO2 or

O2 in the gas.

The possibilities offered by BORSIG Membrane Technology at a

glance:

• BORSIG Fuel Gas Conditioning Gas treatment for pipeline, gas engine and turbine

applications

• BORSIG Oxygen Enrichment Oxygen enrichment for combustion processes

• BORSIG Gas SeparationBulk separation of gas stream

• BORSIG Biogas Processing Membranes and systems for biogas treatment

Process concepts in addition or as an alternative to conven-

tional process solutions.

Gas treatment for pipeline, gas engine and turbine applications

Fuel gas taken from the sources available at site and in particular in re-

mote production locations often does not meet the high quality standards

required for pipeline injection or for utilisation in modern high efficiency

gas turbines or engines.

The Application

The fuel gas quality is typically specified in terms of minimum methane

content, methane number, dew point or calorific value or other closely re-

lated parameters. All these parameters are determined by the content of

higher hydrocarbons in the fuel gas. Hence in order to increase the fuel

gas quality with respect to these parameters a selective removal or signi-

ficant reduction of the content of these C3+ components is desired.

The BORSIG Solution

The BORSIG membrane technology for hydrocarbon separation provides

a simple, cost saving and highly reliable solution for fuel gas upgrading

and calorific value control.

The raw gas is taken directly out of a high pressure line at site or com-

pressed by a separate compressor and routed to the membrane unit.

The heavier hydrocarbons (C3+) are separated preferentially and are con-

centrated on the low pressure side of the membrane, whereas the lighter

components, mainly the methane and ethane, remain at high pressure.

This lean residue of the membrane provides the high quality fuel gas to

be utilised in the gas motor or turbine or to be injected into a respective

pipeline. The enriched permeate stream is routed to a low pressure line at

site or typically recycled to the compressor suction.

Because the membrane provides also a separation capability for water the membrane will also allow a certain degree of dehydration simul-

taneously with the hydrocarbon separation. This may be sufficient to

achieve the required water dewpoint specification and to reduce the risk

of hydrate formation.


• High C3+ removal

• High equipment reliability and on-stream availability

• Completely assembled compact process units

• Easy integration into existing facilities

• Minimum of supervision and maintenance

• Prolonged life time of gas turbines or engines and related components• Particularly suitable for offshore applications and remote locations

Gas ConditioningBORSIG Fuel Gas Conditioning



Oxygen enrichment for combustion processes

Various processes requiring oxygen are just being fed with air.

Typically higher process efficiency or product yields can be

achieved when operating these processes with a gas stream

with higher oxygen content than provided by ambient air.

The BORSIG membrane technology provides an attractive solu-

tion to generate oxygen enriched feed gas streams utilised for

instance in combustion or chemical process applications.

Bulk separation of gas stream

CO2 SEPARATION

CO2 gas separation applications are found within a wide range

of operating pressures and feed gas compositions. Typically in

dependence on the actual application also the requirements

regarding product purity and separation efficiency do vary within

a wide range. Main applications are for instance biogas and

natural gas treatment or more general CO2 separation/recoveryfrom process off gas streams. The membrane technology pro-

vides efficient and cost effective solutions for CO2 separation in

a wide range of these applications.

Natural Gas Treatment

Nowadays a significantly increased percentage of worldwide

gas production is dealing with natural gas containing consi-

derable amounts of CO2. A typical CO2 content is within the

range of 5 to 15 %. In order to maintain the gas quality and to

meet pipeline specification requirements efficient and economi-

cally viable CO2 separation technologies have to be applied.For a wide range of applications in particular for small and me-

dium gas flow rates the membrane technology can provide

interesting process concepts in addition or as an alternative to

conventional process solutions.

Membranes and systems for biogas treatment

With the recently increasing efforts to utilise renewable energy

sources biogas is considered to be one of the major options for

providing a significant share in the modern energy mix. To use

this source the produced raw-biogas is processed and treated in

order to meet the gas specifications required for utilisation.

The Application

A raw-biogas generated by fermentation contains methane (typi-

cally 50 to 60 %) and CO2. In order to utilise the bio-methane

for the injection in the gas distribution network or as fuel gas for

motors or turbines for energy production the raw biogas is trea-

ted and upgraded accordingly.

The BORSIG Solution

The BORSIG membrane and process technology enables an

efficient CO2/methane separation process to provide the pro-

duct gas at the required purity while reducing the loss of metha-ne.

The biogas treatment process set-up comprises

• Filter/coalescer for free water removal

• Desulphurisation if required to meet respective pipeline

specifications of network operator

• Gas compression

• Membrane separation

• Product gas metering and conditioning (odoration, etc.) –

to be provided by network operator


• Reduced scope of equipment, reduced size and weight

• Minimum mechanical complexity:

Static system / no moving parts / easy to operate

• No additional chemicals or refrigerants required

• Flexible modular design

• Completely prefabricated containerised solution ready for

installation and operation

These advantages allow attractive process solutions for biogas

processing already for operators of biogas plants within the

lower capacity range.
