Abstract
A delayed coking process in which part of the coke produced is heated by partial burning and mixed with preheated coker feedstock to raise the temperature of the coking mass present in the coking drums. The rapid heat transfer thus obtained brings about some immediate flashing of volatiles and makes possible higher than usual temperatures in the coking drums. The results are a reduction of residence time in the drums and an increase in the yield of volatile products. Hot coke in excess of that required to heat the feed may be gasified. Thus, resultant net coke yields are lower than the conventional delayed coking process.
