Abstract (en)
[origin: WO2014023526A1] The invention relates to a method for removing aromatic hydrocarbons from coke oven gas (COG), wherein biodiesel is conducted in a circuit as a washing liquid. The coke oven gas (COG) is brought into contact with the biodiesel in a first gas scrubbing stage (3) to separate aromatic hydrocarbons. The biodiesel, enriched by aromatic hydrocarbons, is then withdrawn from the first gas scrubbing stage (3), heated and regenerated by stripping using water vapor. The biodiesel, regenerated by stripping, is then supplied to the first gas scrubbing stage (3) again after cooling. According to the invention, the coke oven gas (COG) cleaned in the first gas scrubbing stage (3) is supplied to another, second gas scrubbing stage (4), to which a more strongly output partial volume of the biodiesel is supplied as washing liquid.
