A comparison of four petrochemical refining schemes producing 600,000 tons/yr ethylene from 33/sup 0/ API Arabian light crude, i.e., vacuum gas oil (VGO) catalytic cracking and vacuum residua desulfurization (Case I), VGO catalytic cracking and vacuum residua conversion with the C-E Lummus/Cities Service Co. LC-Fining process (Case II), VGO desulfurization and LC-Fining (Case III), and VGO hydrocracking and LC-Fining (Case IV) showed that in Case II, the crude throughput was approx. 8000 bbl/day lower and that the ethylene transfer price was $378/ton, compared with $393/ton for Case I. The ethylene transfer price is $410/ton for Case III and $419/ton for Case IV, which indicates that the additional investment needed for VGO hydrocracking, instead of desulfurization, is not economically justified unless the increased yields of products such as benzene, p-xylene, o-xylene, and propylene are important to the producer. The results indicate that the production of finished gasoline as well as petrochemicals is more economically attractive than the production of petrochemicals alone. Disposal of the pyrolysis fuel oil by-product, i.e., by Maruzen's needle coke production method, is discussed.
