In early October, reporters learned from Jinxi Petrochemical that this company is market-oriented, insists on maximizing benefits, accurately seizes the opportunity of increased domestic gasoline demand, and increases production by optimizing production operations. High grade gasoline. In September, the company's gasoline output reached 223,000 tons, of which No. 95 gasoline accounted for 23%.
In order to optimize the work of increasing gasoline production, Jinxi Petrochemical has strengthened process discipline management and strictly controlled operational changes to ensure stable operation of public projects and achieve safe and stable production.
On the premise of ensuring safe production, Jinxi Petrochemical established a gasoline production optimization team to comprehensively optimize the production process based on market demand and production plans, dynamically monitor gasoline production in real time, and promptly adjust plans for increasing high-grade gasoline production.
Jinxi Petrochemical uses process simulation to optimize its production plan, and determines two sets of catalytic gasoline production plans based on the types and properties of processed crude oil; by controlling the gasoline end point of the north and south distillation units, it improves the gasoline fraction yield; adopts new catalyst formulas, Measures such as optimizing the addition ratio, increasing the olefin content of gasoline, and adjusting the reaction temperature and increasing the conversion rate were used to increase the butene and isobutylene content and gasoline octane number in the two sets of catalytic liquefied gas. After optimized operation adjustments, the company's gasoline yield increased by 1%, and the olefin content in liquefied gas increased by 2%.
Jinxi Petrochemical continues to optimize the balance of reforming raw materials throughout the plant, increases the production of naphtha in the hydrocracking unit, and achieves full-load operation of the reforming unit. The company has minimized the load of the natural gas hydrogen production unit, reducing natural gas consumption by 2,000 standard cubic meters per hour; reduced the octane loss of the mixed product through the side-stuck operation of the distillation outlet of the gasoline hydrogenation unit; optimized the production of the alkylation unit and MTBE unit, Increase the production of high-octane, low-olefin gasoline components.
Jinxi Petrochemical's gasoline production optimization team dynamically grasps the properties of gasoline fractions, uses process simulation and small tuning tests to optimize the gasoline blending formula and avoid excess octane quality of the blended product.
