Abstract: The effect of technical transformation for process direction of delayed coking condensate in Sinopec Luoyang Company was introduced. Considering the present process flow, a transfer line from condensate drum to VGO outlet of fractionation tower was added in order to withdraw the high temperature condensate (greater than 200 ℃) and VGO together from the fractionation tower, instead of recycling process of the heavy condensate. This ensures the operation stability of fractionation tower during coking tower preheating.
