| Delayed coking process has become one of the important heavy oil processesbecause of its excellent profit, high conversion and high ratio of diesel to gasolineyield. So far , the development of Delayed coking process already has been advancedby leaps and bounds .Regardless from the process, the material choice of theequipments, still equipments of large turn up, all become more economic reasonable,and the investmentIs saved.Delayed coking unit of JINZHOU petrochemical company hadannual capacity of 1000 thousand tons Original.For increasing the ability of handling.It is necessary to reform the Delayed coking unit . This reformation adopted theproduction craft of a big tower forerunner, The annual design ability of single toweramounts to1000 thousand tons annual,This craft is also something to lead in theworld.This text studies the influence of various operation conditions Of Delayed cokingunit to the product function and product distribute, found out the method of increasingratio of diesel to gasoline yield.and increasing the yield of gasoline and dieseland thecapacity of processingand increasing the economic performanceDelayed coking process of JINZHOU petrochemical company was modeledusing Pro-â…¡ simulation software to simulate the whole process and find out the factorof restricting. And operation parameters, equipment size and technical flow aredetermined by simulation. Mean while the expending of the equipments is lowed asmuch as possible and eligible production is produced .In addition, we also investigatethe design of the equipments,autocontrol level the protecting of environment, safetyissue and economic evaluating in magnifying the project. |
