On August 21, 2024, the key components of the China Coal Yulin coal deep processing base project: the EPC general contracting project launch conference for the olefin separation unit and liquid storage and transportation project was successfully held in Guangzhou.

China Coal Shaanxi Energy and Chemical Group Co., Ltd. is located in the east of B1 Road North, Yuma Avenue, High-tech Industrial Park, Yulin City, Shaanxi Province. The first phase of the equipment has an annual output of 2.05 million tons of methanol, 600,000 tons of polyolefin equipment and supporting public works. It has been completed in It was completed and put into production in July 2014.

The estimated investment for the second phase of the coal chemical industry project is 23.888 billion yuan. It will build a coal-based raw material with an annual output of 2.2 million tons of methanol and 900,000 tons of olefins and related supporting facilities. At the same time, it will optimize and upgrade the existing first-phase project to build a low-cost coal chemical plant with an annual output of 250,000 tons. Density polyethylene, ethylene-vinyl acetate copolymer chain extension and supporting engineering projects.

China Coal Shaanxi Co., Ltd.’s second phase coal chemical project is the first in China to formulate a full life cycle carbon neutrality roadmap in the design stage; it has embedded genes such as green and low carbon, high-end diversification, digital transformation, advanced technology, and high-end products, and through technology Technology integration, multi-energy complementary coupling, energy cascade utilization, first- and second-phase interconnection, etc. can significantly reduce material and energy consumption and improve resource conversion rate.

At the same time, China Coal Shaanxi Company has eliminated coal-fired boilers, greatly increased the proportion of electrification, and zeroed out coal as fuel. Relying on new photovoltaic projects to replace external power supply with green electricity, green hydrogen and green oxygen will be used as hydrogen and oxygen sources in the coal chemical industry to capture The collection and recovery of high-purity carbon dioxide by-products of the device has achieved the goal of developing coal, utilizing coal, and surpassing coal; taking comprehensive measures that combine source carbon reduction, process carbon reduction, and end-use carbon, the comprehensive energy consumption and carbon reduction of coal-to-olefins Emissions will reach the leading level in the "Modern Coal Chemical Industry Carbon Emission Benchmark".

After the project is successfully put into operation, it will achieve dual optimization of energy consumption and emissions. The standard coal consumption per ton of olefin products will be reduced from 1.8 tons to 1.75 tons, significantly improving energy utilization efficiency; at the same time, the carbon dioxide emission intensity of unit olefin products will be reduced. to 6.83 tons, which is far lower than the industry’s advanced benchmark of 32.48%. The annual carbon reduction is as high as 1.15 million tons, demonstrating strong environmental benefits. In addition, the project's clean energy conversion efficiency reached 47.7%, 3.7 percentage points higher than the industry's advanced value, reflecting the perfect combination of efficient energy conversion and green production.Editor/Jiang Mingyue
