Reduction of coker furnace tube fouling in a delayed coking process |
摘要 |
In a delayed coking process, furnace tube fouling is minimized by including a measured amount of full boiling range heavy gas oil as an additive in the furnace feed, preferably by forced recycle from a heavy gas oil stream. An additive is preferably supplied directly to individual furnace tubes by multiple circumferential injection upstream of each tube receiving the additive.
