ABSTRACT

Resid FCC i s compared with resid hydro- cracking (H-Oil) and visbreaking in a grassroots setting. Economics based on 1989 crude and product prices are compared with those of 1983. Sensitivity evaluations include the effect of crude quality (light through heavy) and the price of heavy fuel oil relative t o crude price.

INTRODUCTION

Industry experts are predicting the return of a more traditional price spread between light and heavy crudes, a significant reduction in the demand and price of heavy fuel o i l , and a trend toward processing heavier crude blends. Such events would accelerate interest in the installation of new resid conversion
faci 1 i t i e s .

Because the planning, design, and construction of new f a c i l i t i e s require years of lead time, many refiners are currently evaluating their alternatives. Throughout Europe, for example, where cleaner gas i s predicted t o replace high sulfur fuel o i l , studies not unlike those of the late 70s and early 80s are being performed.
are comparing the merits of the available proven technologies. One resid hydrocracker project has already been announced in northern Europe, and others are in late stages of planning.

CONCLUSIONS

Overall conclusions of this study can be summarized as follows:

0 New resid conversion f a c i l i t i e s w be needed. Projects should begin now. To meet the changes in high sulfur heavy fuel oil demand requ three years lead time. H-Oil and resid FCC technoloqies are

0 Based on 1989 crude and product prices, the internal rates o f return ( I R R ) show an advantage for resid FCC with light crudes, and visbreaking with heavy crudes. (H-Oil unit conversion i s set a t 65% f o r these comparisons .)

IRRs are slightly higher than the other processing schemes for light crudes, and significantly higher for the heaviest crudes.

0 For both sets of prices, 1983 and
1989, processing heavier crudes are shown t o be significantly more profitable than processing lighter crudes, regardless of the processing scheme selected.
