Over the past decade Fluid Catalytic Cracking has become the most popular process for conversion of heavy feedstocks into lighter products. Stone Webster offers the S W FCC process to serve this market and operations in eleven full technology applications as well as many revamps employing elements of S W FCC technology have confirmed and further refined the essential features of this process. These features include: Reaction System (feed injection nozzles, riser quench technology, riser terminator/separator, and staged catalyst stripping); and Regenerator System (two stage concept and environment for maintaining catalyst activity). S W FCC accomplishes high yields of valuable products, low coke and dry gas make, coupled with the flexibility to process a wide range of feedstocks into desired yield slates. These objectives have been accomplished in a system designed for longer safer run lengths between turnarounds, and low operating capital costs. In addition to new units, the elements of this technology have found application in many revamps from vacuum gas oil (VGO) to residue operations. This has been accomplished by incorporating one or more elements of the S W FCC or in several cases by complete conversion of the reactor/regenerator to the S W FCC technology.
