Process Modification and Operation Scheme Optimization of Delayed Coking Cold Coke System
On the basis of long-term analysis and comparison of the operation process of the cold coke water system in the delayed coking unit,the technological transformation and operation method optimization of the cold coke system in the delayed coking unit were carried out,in order to solve the problem of excessive gas phase load of T104 contact cooling tower in the coke tower cooling process of the original coking unit,serious emulsifying oil and sulfur containing sewage at the top of the contact cooling tower were caused,and more coke powder was carried by the following coker fractionation unit,the system fluctuates greatly,the diesel backwash filter SR105 recoils frequently,and the steam generator SG102 produces too much steam,causing waste.The utility model enables the delayed coking unit to run safely for a long time,and reduces the use of systems engineering 1.0 MPa steam,reduces the operation cost of the unit,and improves the operation efficiency of the unit.
