The Dolun Shiteng coal-to-olefins by-products aromatization project was invested in and constructed by Inner Mongolia Dolun Shiteng Chemical Co., Ltd., with a total investment of 330 million yuan. It falls under the category of projects aimed at the downstream recycling of by-products from Datang Coal Chemical Industry; it uses liquefied gas and mixed aromatics generated by Datang Coal Chemical Industry as raw materials to produce high-value fine chemical products. The project’s designed raw material processing capacity is 150,000 tons per year, allowing for the processing of 50,000 tons of liquefied gas and 100,000 tons of mixed aromatics per year. Construction began in March 2014, and work resumed in May 2017; it is now supplying recycled water to Datang. It is expected that all remaining projects will be completed by May 2018, followed by full-scale trial operations of the entire system. Dolun Shiteng Chemical Co., Ltd. is located in the Dolun New Industrialized Chemical Zone in Nuoer Town, Dolun County, Xilin Gol League, Inner Mongolia, to the west of Datang Inner Mongolia Dolun Coal Chemical Co., Ltd., with a registered capital of 100 million yuan. The 150,000-ton coal-to-olefins by-product aromatization project, invested and constructed by the company, is the first such project of its kind in China. It utilizes advanced domestic full-range deep aromatization technology to carry out further processing of the liquefied gas and aromatic oils that are by-products of Datang Dolun Coal Chemical’s production processes; the main products generated are high-value organic chemical substances such as pure benzene, toluene, xylene, trimethylbenzene, and propane.
