Progress in the Construction of the Deep Processing Project for Heavy Aromatics and Polyhydrocarbons at Yili Xintian Coal Chemical Industry Co., Ltd. Author/Source: Huahua Network – Coal Chemical Industry. Date: July 9, 2020. Clicks: 7. At 10 a.m. on July 6, construction work on the pile foundations and civil engineering aspects of the deep processing project for heavy aromatics and polyhydrocarbons at Yili Xintian Coal Chemical Industry Co., Ltd. officially began. The heavy aromatic hydrocarbons and polyhydrocarbons deep processing project of Yili Xintian Coal Chemical Co., Ltd. is a downstream modification project of Xintian Coal Chemical’s coal-to-natural gas project. With a total investment of 73.86 million yuan, it falls under the category of renovation and expansion projects. It is located in the reserved area to the southwest of the coal-to-natural gas project within the Yili Xintian Coal Chemical Circular Economy Industrial Park. The project involves the construction of a deep processing facility capable of handling 200,000 tons per year of heavy aromatic hydrocarbons and polyhydrocarbons. The project mainly includes a distillation unit, a finished product tank area, oil loading facilities, and a ground scale system, with completion scheduled by the end of April 2021. The Yili Xintian Coal-to-Gas Project is located in the Yili Xintian Coal Chemical Industry Park in Yining City, Yili Kazakh Autonomous Prefecture, Xinjiang Uygur Autonomous Region. It produces 2 billion cubic meters of pure natural gas per year, with by-products including 31,000 tons of light hydrocarbons, 100,000 tons of heavy aromatics, 84,000 tons of polyhydrocarbons, 25,000 tons of polyphenols, and 116,000 tons of thiamine. The total investment in the project is 16.09 billion yuan, funded jointly by Zhejiang Energy Group Co., Ltd. and Shandong Energy Xinwen Mining Group Co., Ltd. The Huahua Network coal chemical project is able to convert 6.77 million tons of coal into 2 billion cubic meters of natural gas each year, which is sent to Zhejiang and accounts for about one-third of Zhejiang’s current natural gas consumption. With the increasing environmental regulations, the heavy aromatics and polyhydrocarbons generated during coal-to-natural gas production are classified as hazardous waste under the **Hazardous Waste List**. To protect the environment, achieve sustainable development, and meet the goals of reducing costs and improving efficiency, this company processes these substances further. At the same time, this project lays a solid foundation for the diversification of by-products in Xintian Coal Chemical Industry. Once it is put into operation, it will carry out fractional distillation of heavy aromatics and polyhydrocarbons to produce products such as phenol oil, washing oil, anthracene oil, and coal tar pitch. This improves the marketability of these products, enables more efficient use of resources, and plays an important role in helping the company achieve environmental improvements as well as enhanced economic benefits.
