Upgrading FCC VRU can yield attractive economic payoff

Debottlenecking the vapor recovery unit (VRU) in a fluid catalytic cracker (FCC) can release unused cracking capacity and defer a major VRU revamp. Improvements in VRU capacity and recovery are usually economically justifiable, particularly when propylene is routed to alkylation or petrochemicals. W...

Description
Summary:Debottlenecking the vapor recovery unit (VRU) in a fluid catalytic cracker (FCC) can release unused cracking capacity and defer a major VRU revamp. Improvements in VRU capacity and recovery are usually economically justifiable, particularly when propylene is routed to alkylation or petrochemicals. When an enhancement in VRU performance permits a proportionate increase in FCC capacity or severity, the economic benefits can be incraesed dramatically. VRU debottlenecking technology is examined, with reference to wet-gas compression, suction conditions, discharge conditions, stripping control, product specifications, and de-ethanizer operation.
