发明名称 DISTILLATION OF OLEFINS WITH ALKANOL ADDITION TO PREVENT DEGRADATION
摘要 The disclosure describes methods of improving the operation of olefin fractionation systems wherein residual materials contained in the olefins catalyze side reactions of the olefins during the distillation operations or subsequent thereto. The improvement is obtained by the addition of alcohols of selected molecular weight at several critical locations in the system, one location in particular.
