Biogas consist of Hydrogen sulphide (H2S), which is hazardous to any engine or any equipment in which the biogas is used. Due to this reason, it should be removed before the biogas is used.

Complete turnkey solution is endorsed, starting from design to power generation including BIOCLEAN™ solutions, for the removal of Hydrogen sulphide (H2S) before use in biogas engine.

Further, removal of CO2 and other impurities from Biogas gives purified Methane for bottling to use in domestic or industrial applications. Biogas composition may vary from substrate to substrate, feed stock composition fed into reactor for degradation of organic compounds. We will provide BIOCLEAN™ solution based on client requirements / demand on particular locations.

We offer turnkey solutions for the Bio- Methane (>95%) & Bottling technology. There are many methods available & each has its own advantages and disadvantages but most commonly used method is PSA techniques.

1. Pressure Swing Adsorption (PSA): An adsorption technology operated under pressure of 3-10 bar to remove Moisture, CO2, and H2S from raw biogas.

2. Water Scrubber: In a Water Scrubber, CO2 & H2S is separated from the raw biogas and dissolved into the water in the absorption column by using high pressure, normally 6-10 bar.

3. Membrane Separation: A membrane technology for Upgradation of biogas and operated at high pressure of 5-20 bar.

4. Cryogenic Separation: Here, Methane and Carbon dioxide are separated by gradually cooling down the raw biogas. All compounds with higher condensation temperature than methane, such as water, hydrogen sulphide, siloxanes and nitrogen, can be separated in this process.

Biogas, like Liquefied Petroleum Gas (LPG) cannot be converted into liquid state under normal temperature and pressure. It liquefies at a pressure of about 47.4 Kg/cm2 at a critical temperature of -82.10C. Removing carbon dioxide, Hydrogen Sulphide, moisture and compressing it into cylinders makes it easily usable for transport applications as fuel for vehicles & also for stationary applications. Also raw biogas can be compressed and bottled for remote applications of biogas. The compressed biogas can be used for injection into CNG Grid, Fuel for Vehicles, household and industrial application of biogas. It creates revenue when generated and sold for remote applications.
