Syngas & Biogas Cleaning

Whether the requirement is for cleaning tars from biogases generated from a hot gasification process, or sulphurous compounds or VOCs from biofuels generated from an anerobic digestion process, V-tex® can be the solution. Gasification of waste bio-materials (eg, wood chips) produces a hot fuel gas that is cooled and cleaned and then fed into an engine driving a power generator. As the gas is cooled the tars present begin to condense (usually 90-120°C) forming viscous sticky liquids that cause fouling. V-tex® offers the power plant engineer a self-cleaning, high-efficiency, compact heat-exchanger that will remove all condensibles ahead of his blower or compressor. Biofuel gases can be produced from sewage works, landfill sites and by the anaerobic digestion of organic waste materials. These gases are cool so contain fewer condensables. Instead, they contain other compounds that can foul blowers, compressors or engines including sulphurous compounds (eg. H2S,mercaptans) or VOCs (eg. styrenes, xylenes). Once again, the power plant engineer needs a self-cleaning, high-efficiency, compact reactor that will remove these compounds from the fuel gas. V-tex® can remove any of these by careful selection of scrubbing-liquor.
