Water associated fraction. The water associated fraction (WAF), sometimes termed the water-soluble fraction (W.S.F.), is the solution of low molecular mass hydrocarbons naturally released from petroleum hydrocarbon mixtures in contact with water.
Method and device for disposing of pollutants in hydrogen production
PCT designated stageWO2026114567A1Hydrogen separationHydrogen/synthetic gas productionCombustion chamberWater vapor
The invention relates to a method and a device for producing a hydrogen product, in which an intermediate product containing water vapor and oxidizable pollutants is formed from a hydrocarbon-containing feedstock and processed to obtain the hydrogen product, wherein water together with oxidizable pollutants is condensed out of the intermediate product to obtain a process condensate (1), from which a deaerator exhaust gas (4) containing water vapor and oxidizable pollutants is removed in a deaerator (D). The invention is characterized in that the deaerator exhaust gas (4) is separated into a water fraction (8) and a gas fraction (7) which is depleted in water vapor and enriched in oxidizable pollutants relative to the deaerator exhaust gas (4), said gas fraction being introduced into the combustion chamber of a process furnace in order to combust the oxidizable pollutants.
