Gas Processing Plant

We are specialists in design and production of components and complete systems for Natural Gas, Biogas, Sewage Gas and Landfill Gas Plants with Upgrading System and for technical and special gas plants with Recovery/Removal/Separation System.

 Biogas is regional available, climate-friendly and very economical now with newly developed membrane technology from Evonik
- SEPURAN® Green Membrane Modules. After years of research, ProVers was able to earn a technological advantage that benefits our customers both in short and long term. 
ProVers sets "Planning and Delivery of profitable turnkey plants at any plant size for customer" as our goal and only motivation. 

Futhermore, it is not only Biogas that we can provide services but also any Recovery/Removal/Separation of specific gases and substance that we could delivery our professional and virtue services to our valued customers.

Engineering

We develop specifically tailored plant models on the respective usage purpose.

In the course of individual engineering the process for the respective customer requirements - concerning methane quality, permeate quality and methane slip as a function of of the raw gas composition - will be optimized.
We have specially developed simulation software, which transfers all process parameters in a complex calculation model to determine the best operating point for the respective operating conditions. 
Equally the plant construction is tuned to the concrete application. No matter if it´s a container plant or the installation in existing or newly built facilities. We plan and produce the plant in accordance with the overall system. Of course our plants comply to the international - as well as to the respective national standards - in terms of quality and process safety.

Energy Saving

Separation process requires only electricity with outstanding energy efficiency but no water consumption, no sewage and no consumption of expendable chemical !!!

Comparing to previous technologies such as pressurized water scrubbing, pressure swing absorption or amine scrubbing, Gas Separation Membrane is relatively simple technology with high efficiency, and its operating cost is the lowest !

Futhermore, moisture contained in the gas is also removed as a side effect of the membrane separation process ;therefore, there is no subsequent gas drying for feeding into the grid required.

Due to the compact construction this technology is particularly suitable to upgrade biogas plants with existing cogeneration units, or to replace old, depreciated cogeneration units without adequate energy recovery.

Because of the high degree of prefabrication,construction times can be drastically reduced. Each plant is fully pre-assembled, tested, technically inspected and passed as a functional unit.
Among turnkey containers the installation of preassembled components in existing or newly constructed buildings is possible in a short assembly time.
The careful choice of components and the high workmanship quality guarantee long term trouble-free operations.

Process and Implementation

Sepuran (Gas Separation Membrane from Evonik) - the key technology to biomethane with natural gas quality

On the way from biogas to biomethane with natural gas quality, the raw gas is first compressed with a high-pressure compressor to 10 - 16 bars.
The heat loss from the compression process can be provided by means of heat exchangers for heat extraction. The pressurized raw gas is handed over to a drying stage with temperature control and further into an activated carbon filter.
Subsequently follows the most important step, the separation of CO2 and aqueous vapor by means of highly selective tubular membranes. This is based on the different permeability of gases in polymers.
The Membrane Module SEPURAN® Green from Evonik is the innovative heart of the plant.
The components for the desulphurization, compression, condensation, filtration and gas separation can be provided as comletely closed container plants. The modular design allows an adjustment to any desired plant size.
The manufacturing is processed in collaboration with GT-Himmel at their site in Korneuburg near Vienna. The plant leaves our factory in modular design, fully pre-assembled, pre-constructed, tested and TÜV-approved.

Mobirise

1-stage process for the integration of existing cogeneration units

Ideal if only a subset of a biogas production should be upgraded into biomethane.

The off-gas is then recycled again and added into the fermenter, the down streamed cogeneration unit can compensate the reduced methane concentration without any problems; the efficiency of the gas engine decreases only slightly.

The operation of Bio CNG service stations - even in intermittent operation - is the primary area of operation for this process concept - but also with this design the feeding into the public gas grid is possible.

Mobirise

3-stage process for obtaining the highest possible yield of methane

Here the highly selective membrane modules are arranged so, that both product gas as well as off gas are each be concentrated several times.

Such a methane slip of less than 0.5% can be achieved.

With this concept, the maximum methane yield is guaranteed, while ensuring the lowest emissions.

The figures below give a quick insight of the economic efficiency. Our calculation models allow the rapid assessment and calculation according to individual parameters.
We can so provide an overview of the economic data of a designed plant using this impressive technology.
