PROCESS FOR IMPROVING PRODUCT YIELDS FROM DELAYED COKING |
摘要 |
<p>Case No. 7066.1 PROCESS FOR IMPROVING PRODUCT YIELDS FROM DELAYED COKING A delayed coking process in which the coker furnace feed is free of conventional heavy recycle. Elimination of this material from the coker furnace feed produces, based on fresh feed to the process, increased liquids and decreased coke. Coker furnace feed is initially combined with a diluent hydrocarbon having a lower boiling range than conventional heavy coker recycle and then transferred to the coker furnace. The hydrocarbon diluent is much lower in coke-forming components than the heavy recycle which is normally combined with the fresh feed and fed to the coker furnace.</p> |
