AirScience Purification Technologies is a Canadian company based in Montreal that designs and builds Biogas Purification Systems and Equipment for bio-digesters and landfill gas applications.   Biogas Purification   Biogas, a combination of methane (CH4), carbon dioxide (CO2) and impurities is a gaseous fuel but also a green-house gas (GHG). As a gaseous fuel, biogas must be purified before being valorized through the production of electricity or of compressed natural gas (CNG).   AirScience Purification Technologies include, biogas desulfurization, biogas dehumidification, biogas siloxanes and hydrocarbons removal and biogas CO2 removal systems. ​ Coke Oven Gas Purification and Valorization ​ Historically coke oven gas (COG) has been used as a fuel for its calorific value, however due to the evolution of gas separation systems and their reduction in price, the extraction of hydrogen, methane or the use of COG as a feedstock to produce hydrogen through COG reforming and water shift reaction or to produce ethanol is now creating much superior value for COG than traditional usage as a fuel.
