HIGH PURITY BENZENE PRODUCTION USING EXTRACTIVE DISTILLATION
摘要
A process is provided for separating benzene from non-aromatics in a highly aromatic stream containing olefins in a concentration range of from about 0.05 to about 5.0, which process comprises predistilling said highly aromatic stream to produce a distilled fraction having a concentration of C8 and heavier compounds of less than about 0.1 wt. percent; and extracting said distilled fraction with a solvent comprising substituted morpholines in an extractive distillation zone to produce a highly-pure benzene stream.
