8. www.ergapc.com Biogas treatment V-tex TM can be the solution for : V-tex TM can be the solution for : cleaning tars from biogases generated by a hot gasification process, cleaning tars from biogases generated by a hot gasification process, sulphurous compounds or VOCs from biofuels generated from anaerobic digestion processes sulphurous compounds or VOCs from biofuels generated from anaerobic digestion processes

9. www.ergapc.com Biogas treatment Hot fuel gas treatment Biogas from gasification of waste bio-materials (eg, wood chips) is cooled and cleaned and fed into an engine driving a power generator. Problem - As the gas is cooled the tars present begin to condense (usually 90-120°C) forming viscous sticky liquids that cause fouling. Problem - As the gas is cooled the tars present begin to condense (usually 90-120°C) forming viscous sticky liquids that cause fouling. Solution - V-tex offers a self-cleaning, high-efficiency, compact solution that will remove all condensibles ahead of the blower or compressor.

10. www.ergapc.com Biogas treatment Anaerobic digestion gas treatment Biofuel gases can be produced from sewage works, landfill sites and by the anaerobic digestion of organic waste materials. Problem - These gases are cool so contain fewer condensibles. Instead, they contain other compounds that can foul blowers, compressors or engines including sulphurous compounds (eg. H2S, mercaptans) or VOCs (eg. styrenes, xylenes). Solution - Once again, V-tex TM is a high-efficiency, compact scrubber that will remove these compounds from the fuel gas, using carefully selected scrubbing-liquor
