| Abstract: | A new type pre riser has been successfully applied in the 800 kt/a FCCU at Jinxi Refinery. The pre riser structure was improved for optimizing the moving track of the catalyst and distributing the pre lift gas properly. The application result showed that the new structure had the advantages of higher contact efficiency of the catalyst with oil, higher catalyst/oil ratio, less coking on the equipment and lower pressure fluctuation as well as better product distribution which resulted in a light oil yield increment of 0.6%. The operation of the system was more smoothly and economic benefit was obtained. |
