Biogas Psa Purification System In Biogas Plant To Remove H2S CO2

Biogas Purication Equipment Description:

Qingdao JCWY offers you turnkey solutions for biogas upgrading suited to your needs: purification, injection, cryogenic distillation, liquefaction. Our experts support you every step of the way, from the design phase to the delivery of the operational unit.

Thanks to the development of several technological bricks, including the CO2 separation membranes our solutions enable you to upgrade all biogases for injection into the natural gas grid, the production of vehicle fuel, liquid biomethane, and the production of renewable hydrogen. The modular systems designed and developed by Air Liquide are upgradeable biogas processing units with processing capacities that range from a hundred to several thousand m3 an hour (100 to 10,000 Nm3/h).

In order to turn the biogas into a substitute for natural gas, we need to remove the carbon dioxide (CO2) and the pollutants. Qingdao JCWY has developed a technical solution that now allows biogas producers to efficiently turn it into biomethane using purification processes. The technology used to separate the two main components of biogas – methane and carbon dioxide – is based on the use of polymer membranes produced by Air Liquide Advanced Separations (ALaS). This efficient system generates biomethane with a methane (CH4) content of between 96.5% and 99%, depending on its purpose. With its technical solution for biogas purification, Qingdao JCWY takes charge of every stage of processing, from when it leaves the digester until it is injected into the gas network.

Biogas Purication Equipment Advantage:

1. Easy to install and easy to use.
2. During the work process, no personnel are required to be on duty, and the materials are renewed regularly.
3. The desulfurization efficiency is high, and the effect of recycling can be achieved by oxidation reduction in the later stage.
4. Fine desulfurization, high precision of desulfurization.
5. Initially low investment and medium operating costs.

Biogas Purication Equipment Working Priciple:

First step: Fe2O3 · H2O + 3 H2S = Fe2S3 + 4 H2O (desulfuration)

Second step: Fe2S3 + 3/2 O2 + 3 H2O = Fe2O3 · H2O + 2 H2O + 3 S (regeneration)

Biogas Purication Equipment Application:

It is mainly used for the removal of corrosive hydrogen sulfide (H2S) gas in biogas, and can also be used for other purification of hydrogen sulfide gas, so that the treated gas provides safety for the normal use and service life of the required equipment.
