Shanxi Quansheng Industrial Co., Ltd.’s new project for producing 1.2 million tons of coal-based ethylene glycol per year (with an initial capacity of 400,000 tons per year). Author/Source: Date: 2016-07-22. Clicks: 7. I. Project Overview: The project to produce 1.2 million tons of ethylene glycol per year from syngas was approved by the Shanxi Provincial Development and Reform Commission under document No. Jin Fa Gai Bei [2016] 100 on April 27, 2016. The project covers an area of 3,000 mu, with a total estimated investment of 15.6 billion yuan. The project is constructed in two phases; the capacity of Phase 1 is 400,000 tons per year, with a construction period of 2 years. II. Construction location: Quansheng Industrial Park, Konggang Economic Development Zone, Yuncheng City, Shanxi Province – Shanxi Quansheng’s new coal-to-ethylene glycol production project with an annual capacity of 1.2 million tons (Phase 1: 400,000 tons per year). III. Plant composition and brief description of the process: This project uses coal as raw material and employs the mature and reliable pressurized coal gasification process to produce crude gas. The crude gas is purified and separated through processes such as partial reforming, low-temperature methanol washing, cryogenic treatment, and pressure swing adsorption, thereby yielding high-purity carbon monoxide and hydrogen ； Dimethyl oxalate is produced by the coupling of carbon monoxide with methyl nitrite, and dimethyl oxalate is then hydrogenated to yield ethylene glycol as the final product. The main equipment includes: 1) 12 flow-bed pure-oxygen pulverized coal gasification units operating at 4.0 MPa, which produce 140,000 Nm3/h of raw gas; 2) systems for modifying the composition of the raw gas by removing oil and sulfur, thereby adjusting the CO/H2 ratio; 3) a low-temperature methanol washing unit that purifies the gas by removing sulfur and carbon; 4) a CO-H2 cryogenic separation unit used to produce H2 and CO from the purified gas; 5) a process using the CO-carbonylation method to produce oxalate esters, followed by further hydrogenation to obtain ethylene glycol; 6) two cryogenic air separation units with a capacity of 32,000 Nm3/h each; 7) ammonia compression refrigeration units that provide the cooling necessary for the low-temperature methanol washing process. IV. Products and Applications The main product is ethylene glycol, with an annual production capacity of 400,000 tons. Ethylene glycol has a wide range of applications: it is used in the production of polyester fibers and resins, as a humectant, plasticizer, and surfactant, as well as in synthetic fibers, cosmetics, and other products. It is also used as a solvent in dyes and inks, as an antifreeze in engines, as a gas dehydrating agent, and in the manufacture of resins. Additionally, it can be used as a wetting agent in cellophane, fibers, leather, and adhesives. It can produce synthetic resin PET, fiber-grade PET and polyester fibers; bottle-grade PET is used to manufacture mineral water bottles and similar products. Alkyd resins, glyoxal, and others can also be produced; it is also used as an antifreeze. In addition to being used as antifreeze in automobiles, it is also employed for transporting industrial heat, and is generally referred to as a coolant; it can also be used as a condenser just like water. It is an important raw material for organic chemical manufacturing, and has broad market prospects as a substitute for petroleum. At the same time, the device produces by-products such as crude ethylene glycol, dimethyl carbonate, mixed alcohols, and sulfur. V. Project construction progress: The first phase of the project is scheduled to begin in May 2016, with design work carried out simultaneously; construction will proceed, and the project is set to go into operation in June 2018.
