Successful performance of a refinery with Eureka unit
- Fuji Oil Co., Ltd., Japan
Since starting in February, 1976, 3,400,000 Kl of vacuum residue (13,000,000 Kl of crude oil equivalent) has been successfully processed in the Eureka unit of Fuji Oil refinery complex and more than 2,500,000 Kl of cracked oil and 1,000,000 tons of pitch have been produced. The operation rate has been 94 to 98% except for the annual shutdown period for inspection. The cracked oil is easily desulfurized to make naphta, diesel oil and a large amount of gas oil (low sulfur fuel oil, 0.1 wt % sulfur). As for the desulfurization of cracked oil, the increase in H/sub 2/ consumption and the decline of catalyst life are observed. However, the operation conditions do not differ much from those for straight run fractions. Processing both hydrotreated and untreated cracked heavy oil (CHO) with FCC unit has proved to be possible. In case of untreated CHO, however, it causes a slight increase in make up catalyst and coke yield. It is demonstrated that heavy crude oils, such as Bachaquero, can effectively be processed in this system. No additional pollution problems have occurred by introducing an Eureka unit to the refinery, although it is located in the district where the most stringent environmental regulations are urged.
