Abstract
A process for recovering maximum amounts of styrene from hydrocarbon fractions produced by thermal cracking of hydrocarbons. The cracked products are subjected to quench cooling and in a separating column separated into a bottom fraction comprised predominantly of hydrocarbons with 9 and more carbon atoms and into a top fraction comprised predominantly of hydrocarbons having less than 9 carbon atoms. The top fraction is fed to a cooling and separating device wherein a cracked gasoline fraction is recovered from which fraction styrene is recovered by fractionation. The cracked gasoline fraction from the separating device can be combined with the hydrocarbon condensates from the first and second compressor stages of a multistage compressor in which the vaporous fraction from the cooling and separating device is compressed.
