On October 6, the 200,000-ton/year polypropylene plant of Zhongke Refinery successfully produced about 2,000 tons of polypropylene product EP332K, breaking the situation of relying on imports for many years, filling the domestic market gap, making Sinopec synthetic resin products Effective progress has been made in the substitution of imports
.
EP332K is the main product of Lyondell-Basell, the world's largest polypropylene product supplier, in China.
This product has excellent properties such as high rigidity, high toughness, and good impact resistance.
It is mainly used for making auto parts, packaging boxes, household items Goods, sporting goods, toys, etc.
, the domestic market demand space is large, and the economic benefits are considerable
.
EP332K is the main product of Lyondell-Basell, the world's largest polypropylene product supplier, in China.
Before switching to production, the plant technicians analyzed the parameter performance of the new brand in detail, continuously optimized and adjusted, carefully formulated the production plan, repeatedly scrutinized the additive formula and production parameters, continuously improved the brand switching instruction list, and carried out the operation risks that may occur during the switching process.
During the conversion process, they carefully operated, timely and accurately adjusted important parameters such as ethylene feed rate, ethylene-propylene ratio and other important parameters to improve product performance; reasonably adjusted parameters such as hydrogen, main catalyst flow rate and electron donor flow rate, and maintained the gas phase reactor pressure as much as possible.
Before the trial production, Zhongke Refining and Chemical actively strengthened contact with chemical sales, Beihua Institute and other units, closely followed the product market demand, increased product development efforts for adjacent melt index, and minimized the generation of transition materials, greatly The energy consumption and material consumption of the device are reduced, and the production capacity of the product is maximized, and the economic benefit is expected to increase by 1.
