Abstract
The invention relates to a process and a plant for staged separation of concomitants from a raw synthesis gas stream to produce synthesis gas and a sulfur-free naphtha product as a by-product, To remove naphtha compounds and sulfur-containing concomitants, raw synthesis gas is treated with a scrubbing medium in a prescrubbing stage and withdrawn from the prescrubbing stage, and the laden scrubbing medium is mixed with water to bring about a phase separation into a scrubbing medium-water mixture and naphtha, wherein sulfur-containing concomitants are in solution in naphtha. To remove the sulfur-containing concomitants the naphtha is heated to obtain sulfur-free naphtha as a by-product of the gas scrubbing.
