Developments in resid cracking technology at Gulf
As conservation measures and standards for new car efficiencies take hold, the demand for gasoline is expected to decline, forcing refiners to meet product demands efficiently with minimum crude. With a reduced market and relatively low price for residual streams, it is very likely that fluid catalytic cracking (FCC) will continue to play a key role in upgrading resids. The economics are overwhelmingly in favor of this strategy. With current price differentials between asphalt and FCC products, the incremental profit for resid cracking at one Gulf Refinery was estimated to be $8/bbl of vacuum tower bottoms cracked. Processing resids poses a number of problems, however. They often contain high levels of sulfur, metals, and coke precursors which may require high catalysts costs, unit modifications and process innovations. Development of promising approaches to handling resids has focused on three key area: 1)catalyst and passivator technology improvemnts; 2)innovations in FCC processing technology; and 3)coupling FCC with other processes. The report presented reviews Gulf's research efforts in these areas. In addition, Gulf's commercial and pilot plant resid cracking data are discussed. (JMT)
