Delay coking process as one improved technological process includes three aspects. Firstly, heavy paraffin base oil from the bottom of the fractionating tower is stored in a material cylinder as independent material directly to realize zero circulation of coking process. Secondly, fresh residual oil material is made to heat exchanged with coking products fully to raise the temperature after heat exchange. Finally, residual oil from tap hole is made to flow into the radiation section of heating furnace, rather than the fractionating tower, to reduce greatly the heat load and fuel consumption of the furnace. The process of the present invention with optimized heat exchange procedure can raise power consumption, increase processing capacity and raise yield of light oil greatly.
