摘要：In a process for obtaining higher-boiling hydrocarbons from a gaseous stream, the latter is first partially condensed and the thus-formed liquid fraction is introduced into a rectification process whereas the gaseous fraction is scrubbed in a scrubbing column using condense residual gas from the rectification. The thus-formed bottom product is likewise passed on to rectification. In order to enhance the scrubbing step by condensed gas, higher hydrocarbons are admixed to this residual gas. Thereby, on the one hand, the residual gas is subjected to improved initial condensation and, on the other hand, the scrubbing effect is enhanced.
