Fouling of equipment in fluid catalytic cracking units can significantly affect unit operation by reducing the necessary transfer of heat in heat exchangers, by restricting unit thruput due to increased pressure drop and, in general, by reducing the overall operating efficiency of the production unit. A loss in heat transfer can result in increased fuel costs to operate the unit or may affect product separation when the lost heat cannot be replaced by other means. The physical restriction of flow can cause production limitations due to increased pressure drop in the system. Pumparound or recycle stream flows may have to be reduced, which will affect heat recovery and product separation. Pluggage in the separation towers can also restrict necessary separation efficiencies and subsequent product separation. The overall unit performance can be adversely affected, even when the flexibility of unit operations exists to compensate for the effects of fouling.
