METHOD OF PROCESSING WASTE GASES IN PROPENE HYDROFORMYLATION

摘要

A process for recovering propene and propene/propane mixtures from the off-gases obtained from the hydroformylation of propene involves contacting the off-gases with a liquid absorbent comprising at least one of the liquid substances formed during the hydroformylation of propene to absorb the propene and propane and thereafter desorbing these gases from said liquid substances.
