March 23 - Recently, the domestic transformation of the core control system DCS of the No. 2 high-pressure unit in the Polyolefin Department of Maoming Petrochemical was successfully completed, achieving the first domestic DCS system for Basel high-pressure tubular process in China to be integrated into the grid and put into operation, filling the gap in the relevant domestic field. Chempricehub analyzes propylene, with a long-short score: 1. The article reports the successful domestic transformation of the DCS system in the Polyolefin Department of Maoming Petrochemical, which improves production efficiency and reliability and is expected to increase the output of polyolefins (such as polypropylene). As a key raw material for polypropylene, the demand for propylene is expected to rise, providing favorable support for the spot price of propylene. At the same time, combined with propylene futures market data (such as contract 2701 opening price of 7,685 yuan/ton, closing price of 7,680 yuan/ton, up 147 yuan), the event may boost market sentiment and drive futures prices upward, as trading volume is low but signals of improved supply and demand fundamentals are strengthening.
