Hot fuel gas treatment Hot fuel gas treatment
Biogas from gasification of waste bio-materials (eg, wood Biogas from gasification of waste bio-materials (eg, wood chips) is cooled and cleaned and fed into an engine driving a chips) is cooled and cleaned and fed into an engine driving a power generator. power generator.
Problem - As the gas is cooled the tars present begin to Problem - As the gas is cooled the tars present begin to condense (usually 90-120°C) forming viscous condense (usually 90-120°C) forming viscous sticky liquids that cause fouling. sticky liquids that cause fouling.

Biofuel gases can be produced from sewage works, landfill Biofuel gases can be produced from sewage works, landfill sites and by the anaerobic digestion of organic waste sites and by the anaerobic digestion of organic waste materials. materials.
Problem - Problem - These gases are cool so contain fewer These gases are cool so contain fewer condensibles. Instead, they contain other condensibles. Instead, they contain other compounds that can foul blowers, compressors compounds that can foul blowers, compressors or engines including sulphurous compounds (eg. or engines including sulphurous compounds (eg. H2S, mercaptans) or VOCs (eg. styrenes, H2S, mercaptans) or VOCs (eg. styrenes, xylenes). xylenes).
