Abstract :
Delayed coking is an important way in the thermal treatment of heavy oil. The process consumes tremendous energy, mainly used to provide reaction heat for the coking process. In this paper, to retrofit a certain delayed coking plant, taking features of the process into account, a scheme is proposed based on pinch technology, in which the waste heat in higher temperature is used to heat the feed instead of by-producing stream. The retrofit scheme can effectively reduce the fuel gas consumption.
