Converting biogas to transportation fuel as compressed natural gas (CNG) is happening today. It is generating far more revenue per cubic meter of biogas than steam or electricity generation. It is the ultimate in the valorization of biogas.

The Terragas process jointly developed by Unitel Technologies and AirScience Technologies, converts biogas from municipal solid waste landfills, anaerobic digesters of waste water treatment plants and other sources to high purity hydrogen.

Hydrogen production through Steam Methanol Reforming (SMR). The methanol feedstock is mixed with water in specified ratio and pressurized. This mixture is passed through evaporator, metering pump and super heater. The hot gas mixture is then fed into a catalytic reactor. The reaction of methanol reforming and the shift reaction, takes place in the catalytic reactor of fixed beds simultaneously to form a mixture of H2 and CO2. Hydrogen is then extracted using the Pressure Swing Adsorption process. AirScience builds hydrogen production plants using methanol or methane as feedstock. Plant capacity is available from a few hundred cubic meter per hour to several thousands.

THE SULFOX REG PROCESS for 0,5 to 3.0 g/Nm³ Concentrations: The SulfoxREG is a gas desulfurization process that convert sulfur in raw gas to concentrated sulfuric acid. The SulfoxREG process is designed for treatment of gas having H2S and CS2 concentrations from 0,5 to 3.0 g/Nm³ (in total). Using a highly efficient regenerative catalytic oxidizer system the plant can be operated without additional fuel or electric energy even at low concentrations.The concentration of the sulfuric acid produced is in the 50% range.
