Abstract
Oppfinnelsen angår en frem-gangsmåte for utvinning av lette C,-hydrokarboner, spesielt etylen og etan, fra en krakkgass, spesielt fra en FCC-avgass. Ifølge oppfinnelsen blir de lette C-hydrokarboner vasket ut av krakkgassen ved absorpsjon med et or-ganisk, fortrinnsvis parafinisk, fysi-kalsk virkende vaskemiddel, hvorved vaskemidlet oppviser en molekylvekt mellom 50 og 75 g/mol, fortrinnsvis mellom 60 og 75 g/mol. Pentan, isopen-tan eller blandinger derav egner seg spesielt som vaskemiddel. Før regene-reringen av det belastede vaskemiddel blir med fordel medutvasket metan strippet ut.The invention relates to a process for the recovery of light C According to the invention, the light C hydrocarbons are washed out of the cracking gas by absorption with an organic, preferably paraffinic, physically active detergent, the detergent having a molecular weight of between 50 and 75 g / mol, preferably between 60 and 75 g / mol. . Pentane, isopentane or mixtures thereof are particularly suitable as detergents. Prior to the regeneration of the loaded detergent, co-leached methane is advantageously stripped out.
