Biogas purification and upgrading,
thermal oxidizers and flares, and gaseous resource valorization,
that's our business-worldwide
AirScience Technologies is a North American company based in Montreal that designs and builds Biogas Upgrading Systems and Equipments for biodigesters and landfill gas applications.
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). It is then referred to as Renewable Natural Gas (RNG) or Bio-methane and the biogas purification process referred to as Biogas Upgrading.
AirScience Purification & Upgrading Technologies include:
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.
AirScience Technologies has become a leader in the valorization of COG over the last five years.
Pyrolysis Gas Purification
Depending on the feedstock being pyrolysed the composition of the pyrolysis gas will contain various contaminants. Prior to the use of this gas as a fuel or as a gaseous feedstock, these contaminants need to be removed. The most common contaminants from the pyrolysis of vehicle tires are hydrogen sulfide and hydrochloric acid.
As part of its Gaseous Resource Valorization strategy, AirScience Technologies has the required technologies to eliminate pyrolysis gas contaminants in the most cost efficient way using single use wet or dry media or regenerative technologies.
As a green-house gas, biogas cannot be vented to atmosphere and must be incinerated in a flare. AirScience Enclosed Flame Gas Flares are specifically designed for biogas incineration. These flares are designed for continuous operation as is the case for landfill gas applications. These flares are also designed for emergency use only which is generally the case in conjunction with biogas purification systems.
Biogas and Landfill Gas Flares,Thermal Oxidizers
As a green-house gas, biogas cannot be vented to atmosphere and must be incinerated in a flare or in a thermal oxidizer in the case of low methane content vent gases. AirScience Enclosed Flame Gas Flares are specifically designed for biogas incineration. These flares are designed for continuous operation as is the case for landfill gas applications. These flares are also designed for emergency use only which is generally the case in conjunction with biogas purification systems.
AirScience Regenerative Thermal Oxidizers (RTO) are specifically designed for the biogas upgrading application where thermal content has rapid and large variations which have proven to be a challenge for typical thermal oxidizers.
