Abstract: Processes and equipment for purification of a sour hydrocarbon mixture or a gas mixture including hydrocarbons and sour gas, at least including the steps of directing the gas mixture to contact an absorbent liquid having affinity for sour gas, providing a purified off-gas mixture, directing the purified off-gas mixture to contact a liquid hydrocarbon mixture, providing an enriched liquid hydrocarbon mixture, with the associated benefit of such a process having a high recovery of hydrocarbons from the gas mixture to the enriched liquid hydrocarbon mixture, while being efficient in removing hydrogen sulfide from the gas mixture. The gas mixture to be purified may either be a natural gas, a fuel gas or an intermediate gas stream, e.g. from naphtha, kerosene, diesel or condensate hydrotreatment or hydrocracking, and it may also include further constituents, typically hydrogen.
