Abstract
One exemplary embodiment can be a method for altering an operation of an alkylation unit during a process upset. The method may include blocking an outlet of a settler to a separation zone, and recycling at least a portion of a hydrocarbon stream to the separation zone to prevent an uncontrolled pressure rise in one or more distillation columns during shutdown of an alkylation reactor.
