Study On Process Technology And Production Scheme Of Clean Gasoline

With the increasing quantity of automobiles, automotive off-gas has become the major pollution in most cities. We must establish a serve gasoline quality standard in order to upgrade gasoline quality find a suitable gasoline quality upgrade scheme for Jinzhou Refining & Chemical Co. Ltd through our work.This paper has fully analyzed the effects of gasoline composition, especially sulfur, olefin and aromatic hydrocarbon, on environment in the view of production and environmental protection. Contrast to foreign and domestic other companies, Jinzhou Refining & Chemical Co. Ltd mainly produces catalyzed gasoline because of the crude oil and the properties of production plants, and exists two major problems, eg. high olefin contents and high sulfur contents.Based on the clean gasoline production technologies including desulfurization, decreasing olefin contents and increasing octane number, focusing on current status of Jinzhou Refining & Chemical Co. Ltd in crude processing and related to the existing production plant, this paper introduces three schemes including making use of GOR-C catalyst and LGO-A assistant catalyst, optimizing operation conditions and applying MGD technology to decrease olefin contents currently. In the future, Jinzhou Refining & Chemical Co. Ltd should adopt petrolatum oil hydrocracking scheme with MIP-CGP technology and produce a clean gasoline which reaches the standards: Europe III and Europe IV.
