Against the background of green and low-carbon energy transformation, Xinjiang Tianye (Group) Co., Ltd. plans an "annual output of 1.5 million tons of intelligent ecological photovoltaic coupled green special resin project" from the perspective of reshaping the industrial structure to create a large-scale and integrated "Coal Chemical-Salt Chemical-Intelligent Ecological Photovoltaic" circular economy industrial chain to realize the development of the chlor-alkali chemical industry from high energy consumption to low-carbon green. It is reported that Tianye Group's original process route requires the use of three raw materials: coal, limestone and raw salt. After adopting new technologies and new processes, limestone is abandoned, reducing raw material consumption by 60%, energy consumption by 40%, and carbon dioxide production. Reduce by 40%, creating a complete, high-yield and green new polyvinyl chloride production route.

    On August 23, the Eighth Division Ecological Environment Bureau issued a public announcement on the approval opinions of the environmental impact assessment documents of the intelligent ecological photovoltaic-coupled green special resin low-carbon transformation and upgrading demonstration project (Phase I) of Xinjiang Tianye (Group) Co., Ltd.

    The project plans to build a 350,000-ton/year ionic membrane caustic soda plant and a 500,000-ton/year polyvinyl chloride (PVC) resin plant.

Construction location: Regiment 147, Shihezi City, Eighth Division, Xinjiang Production and Construction Corps

Project investment: The total investment of this project is 1.39666436 million yuan, of which environmental protection investment is 526.72 million yuan.

    Construction content and scale: The construction nature of this project is new construction. The main construction contents include air separation units, gasification units, conversion and heat recovery units, purification units (low-temperature methanol washing units), PSA hydrogen production units, CO purification units, sulfur recovery units, ethanol units, ethylene units, polyvinyl chloride units, ionic membrane caustic soda units, as well as desalinated water stations, circulating water stations, sewage treatment stations and other related public and auxiliary supporting facilities.

    Relying on Xinjiang's rich coal, salt, limestone and other resources, Xinjiang Tianye focuses on green modern chemical industry, forming a relatively complete integration of "self-contained electricity → calcium carbide → polyvinyl chloride resin and by-products → cement from carbide slag and other wastes" Industrial linkage green environmentally friendly circular economy industrial chain.

    The company's investment projects have an annual output of 250,000 tons of ultra-clean and high-purity alcohol-based fine chemicals and an annual output of 225,000 tons of high-performance resin raw materials are expected to be put into operation in the second half of this year. It is expected to add 250,000 tons/year of high-purity ethanol and 225,000 tons/year of ethylene process VCM production capacity. Source: Petrochemical materials and equipment
