Delayed Coking and LC-FINING Technology a Winning Combination
The high price of oil and increasing global demand for reﬁned products have resulted in unprecedented reﬁning margins, especially for those reﬁners processing heavy, high sulphur crudes. Many reﬁners are reinvesting their proﬁts by upgrading existing reﬁning facilities, focusing primarily on the ability to process heavier, higher sulphur and higher naphthenic acid crudes by adding delayed cokers or ebullated bed hydrocracking technologies. For those reﬁners currently processing light, sweet crudes, the switch to a heavier crude slate and the addition of a delayed coking unit or an ebullated bed hydrocracking unit will signiﬁcantly increase their reﬁning margin.
This paper shows how the combination of delayed coking and ebullated bed hydrocracking can signiﬁcantly increase the conversion capabilities of a reﬁnery versus either technology alone. In particular, the paper shows how the addition of an ebullated bed hydrocracker to a reﬁnery that already includes a delayed coker can improve the economics of the reﬁnery versus the addition of incremental coking capacity. The paper also shows how the addition of a delayed coker to a reﬁnery that already includes an ebullated bed hydrocracker can eliminate the production of heavy fuel oil and improve the reﬁnery economics.
