Technical measures to reduce coke powder carrying of delayed coker

The coke oil products and sulfur-containing water will inevitably carry coke powder because of the particularity of delayed coking process. The reasons and harm of coke producing powder were analyzed. The technical measures of reducing coke powder accompany were introduced in delayed coking unit, including optimization of operating conditions to reduce carrying of coke powder, using of the back flushing filter, cyclone separation, flocculating settling and ceramic membrane filtration method for removing coke powder. After taking the corresponding measures, the problem of carrying the coke powder in delayed coker was reduced effectively, and ensured the smooth operation of the device. The advantages and disadvantages of various methods were analyzed, and the application prospect of technology for reducing coke powder carrying of delayed coker was forecasted.
