It was reported recently that the preliminary preparations for this new facility have been completed; gas supply was established on June 6, and the facility began operations on July 22. In July 2022, the Shanxi Provincial Department of Ecology and Environment issued a decision regarding the environmental impact assessment report for the emergency support project for the comprehensive utilization of coke oven gas by Shanxi Gengyang New Energy Co., Ltd. Project Overview: The project is located in the Fine Chemicals Park of Qingxu Economic Development Zone in Taiyuan City. It utilizes the excess coke oven gas from existing coking enterprises in the development zone to produce 300,000 tons of methanol, 93,500 tons of liquid ammonia, and synthetic natural gas (SNG) per year; part of this SNG is further used to produce LNG. The main construction components include: the pretreatment of coke oven gas, the purification of coke oven gas, the methanol production system, the synthetic ammonia production system, the SNG and LNG production systems, among other core projects; as well as supporting storage and transportation facilities, auxiliary systems, and environmental protection measures. The total investment for the project is 1.56 billion yuan, of which 55.6 million yuan is allocated to environmental protection measures. Qingxu Economic Development Zone is a provincial-level development zone approved by the province, with a total area of 29.99 square kilometers. Its key industries include new coal chemical processing, new energy, new materials, and equipment manufacturing. In February 2020, the Shanxi Provincial Department of Ecology and Environment issued the \"Opinions on the Review of the Environmental Impact Assessment Report for the Overall Plan of Qingxu Economic Development Zone (2018–2035)\\" under document reference Jin Huan Huan Ping Han [2020] No. 69. The fine chemical park within the development zone is based on a coking industry with a total capacity of 11 million tons, comprising Jingyang (4.35 million tons), Meijin (3.85 million tons), and Yaxin (2.8 million tons). It plans to develop three high-end fine chemical production chains: hydrogen production from coke oven gas, carbon fiber production from coal tar, and caprolactam production from crude benzene (used in the manufacture of nylon 66). Aiming for first-class equipment, environmental protection standards, and energy efficiency, this park is designed to be a circular, low-carbon, and green coking industry hub, thereby establishing our province as the \"Hydrogen Capital and Carbon Valley\". The original design for the fine chemical industrial park called for using all of the coke oven gas generated by the 11 million tons per year coking project, aside from what was needed for the coking ovens and the production systems themselves, to support the construction of projects such as those carried out by Shanxi Meijin Huasheng Chemical New Materials Co., Ltd., which involves producing 300,000 tons per year of ethylene glycol and 155,000 tons per year of LNG, as well as a project for producing 2,000 Nm3/h of industrially high-purity hydrogen. It also covered projects undertaken by Shanxi Xiaxin New Energy Technology Co., Ltd., which involve producing 300,000 tons per year of methanol along with 100,000 tons per year of synthetic ammonia. With the completion and commissioning of the coking facilities and related chemical projects in the park, issues such as the safety and risks associated with the sole use of coke oven gas in this park have gradually become apparent. To address this issue, the development zone has attached great importance to it. In order to completely eliminate potential risks, it organized numerous in-depth discussions among the three enterprises in the park – Meijin, Gengyang, and Yaxin – as well as design firms, along with experts in areas such as coking, environmental protection, and safety. As a result, an emergency support project for the comprehensive utilization of coke oven gas was developed in the park, and the design plan for this project was further improved to ensure that all coke oven gas is utilized, thereby addressing the shortcomings of the original design and minimizing the safety hazards and environmental risks that could arise from the release of gas. The project is planned to be constructed by Shanxi Gengyang New Energy Co., Ltd., which has the largest coking production capacity in the park. The product plan for this project includes the production of 300,000 tons of methanol per year from coke oven gas, along with 93,500 tons of liquid ammonia and 12,500 Nm3/h of synthetic natural gas (SNG) to be supplied to the urban gas network; part of this SNG will also be used to produce LNG.
