Since May, the two sets of polypropylene plants of Sinopec Refinery have made in-depth analysis and research on the parameter performance of the imported product brands, carefully formulated production plans and additive formulas, and actively communicated with sales in South China to find brands.
Since the additive amount of this brand is twice that of other products, it is prone to excessive feeding in the additive system, overloading of the current, and stoppage of the metering scale, so that the melt index of the product does not meet the standard, which affects the quality of the product
.
During the production conversion process, the team members carefully operated, timely and accurately adjusted important parameters such as ethylene feed amount, ethylene propylene ratio and other important parameters to improve product performance; rationally adjusted parameters such as hydrogen, main catalyst flow and electron donor flow to further shorten the switching cycle and ensure product quality.

The planned trial production of 2,000 tons of EP540P is expected to increase economic benefits by 1.
