ABSTRACT:
A refinery derived spent caustic is recycled by introducing the spent caustic to a delayed coking drum while conducting delayed coking of a hydrocarbon feedstock. The alkali metal containing material accelerates coking, induces production of shot coke, alleviates the problem of a hot drum and reduces drum cooling time.
