Adopting Ifp Technology For The Revamp Of Fcc

As the quality of crude oil produced becomes more and more inferior, the processing capacity of FCC, as the very core of refinery, attracts more attentions. In order to reach the capacity of 10 million tons per year of the overall scheme of the refinery, Dalian West Pacific Petrochemical Co Ltd (Wepec) began to review and study the potential problems/bottlenecks coming from the FCC revamp since 1998. Following many discussions with the foreign licensors and domestic experts, finally they decided to adopt IFP technology for the FCC revamp. The project was accomplished in 2007, which increased the FCC capacity into 2.8Mt per year and enabled the refinery to reach the 10Mt per year capacity.In view of the industrial production practices of the original FCC unit, a study has been conducted from the basic theory to the optimization on the industrial unit. The thesis elaborates in detail the main reaction mechanism and technology of FCC, introduces the processing route of Wepec, and emphasizes on the application of IFP technology and the operation status after the revamp. A lot of data implies that the success of FCC revamp enabled Wepec to achieve the 10th five-year plan. The capacity of the refinery increased from 5Mt per year to 10Mt per year and the crude API dropped from 35.8 to 35. This change is of significant importance under the market environment of large price differentials between light and heavy crude oils. The conclusion of the study will be applicable to a certain extend to similar FCC units.
