Contaminant metals in spent catalyst from a fluid catalytic cracking unit can be removed by passing the spent catalyst through the Demet Process. The resulting demetallized and reactivated catalyst can be returned to the cracker from which it originated, thereby replacing fresh catalyst. Then spent catalyst disposal can be eliminated and stack losses can b minimized. A 20-tdp Demet plant has successfully demetallized and reactivated offsite fluid catalyst since April 1988. This has resulted in significant savings for the refiners. The Demet process could also be installed at the cracker site. The advantages of an offsite plant are that it can be large and centralized. The advantages of a unit built at a refinery are that catalyst transportation costs are eliminated and chemical costs are reduced. This article discusses onsite demetallization. An onsite unit is shown.
