Refinery oily hazardous wastes (sludge) can be recycled to the delayed coker unit. Processing the waste to achieve proper conditioning can increase the waste solids loading to the coker, improve coke quality and reduce coker operational problems associated with unprocessed sludge injection. This paper discusses the processing steps required to achieve maximum solids loading, potential cost savings, and project data from two major refineries that are processing sludge prior to coker recycling. This presentation is an update of one made to the API Environmental Symposium on May 11, 1993 in Toronto. The data presented in Toronto was gathered over the first twelve months after this recycling method was introduced in 1992 to the two refineries for which data are given. This paper adds data through 1994.
