On April 28, it was announced that Xinjiang Zhongcai Pipeline Co., Ltd. won the bid for the procurement of double-wall corrugated pipes for Hengyi Energy Technology (Turpan) Co., Ltd.’s project to produce 2.4 million tons per year of coal-based ethylene glycol for high-quality fibers. On April 15, the China’s first long-distance ethylene glycol pipeline project (115.2 kilometers) was awarded to Zhongyuan Design Company of PetroChina Engineering Construction Corporation, thereby establishing a route for transporting the product outside the region. From April 9 to 11, the review meeting for the process package of the gasification unit of the 2.4 million tons/year project for producing ethylene glycol from coal for high-quality fibers, undertaken by Hengyi Energy Technology (Turpan) Co., Ltd., was successfully held at Guizhou Aerospace Maiwei Technology Co., Ltd. This project utilizes five 3,500-ton semi-waste heat boiler gasifiers supplied by Aerospace Maiwei. The current process route has been finalized, and the project has entered the stage of detailed design and equipment procurement. Project name: The 2.4 million tons/year project for producing ethylene glycol from coal for high-quality fibers by Hengyi Energy Technology (Turpan) Co., Ltd.
Construction location: The project is located in the Coal-based New Materials Circular Industry Park within the Turpan Economic Development Zone. The central coordinates of the site are: 89°5'8.868" E longitude and 42°39'58.415" N latitude.
Constructor: Hengyi Energy Technology (Turpan) Co., Ltd.
Project overview: This is a new construction project aimed at producing 2.4 million tons of polyester-grade ethylene glycol per year. Additionally, it will generate 52,120 tons of ethanol, 76,000 tons of dimethyl carbonate, 32,485 tons of sulfur, 28,404 tons of liquid ammonia, and 24,500 tons of nitric acid (50% wt) annually as by-products. The main components of the project include: (1) The core facilities consist of 10 units, such as a gasification unit, a shift unit, a low-temperature methanol washing unit, a sulfur recovery unit, a hydrogen and carbon monoxide separation unit, a dimethyl oxalate unit, an ethylene glycol unit, an ammonia synthesis unit, a nitric acid production unit, and an air separation unit. (2) Auxiliary engineering includes water supply, circulating water stations, drainage and recycled water systems, desalination stations, power supply, heating, air compression stations, fire protection, maintenance, flare systems, heating and ventilation, office and living facilities, a central laboratory, as well as telecommunications facilities. (3) Storage and transportation engineering mainly includes the storage and transportation of solid materials, the storage and transportation of liquid materials, coal storage and transportation, as well as internal roads. (4) Environmental protection projects include supporting measures for air pollution control, water pollution control, noise control, environmental risk prevention, as well as facilities for temporary storage of solid waste. The project covers an area of 253.75 hectares, with a total investment of 2,570,180.85 million yuan, of which 1,550,000 million yuan is allocated to environmental protection measures, accounting for 6.03% of the total investment. The project utilizes Pu Jing Chemical’s complete ethylene glycol process technology and proprietary catalysts, with China Chengda responsible for the engineering design.
