The gasification framework for Jineng Holding Group’s gasification upgrade project has been completed! 12 new pure-oxygen continuous gasification units are to be built. It was recently reported that, as of August 2025, the construction of the pure-oxygen continuous gasification units as part of the project aimed at improving energy efficiency and sustainability in gas production at Tianyuan Shanxi Chemical Co., Ltd., which is part of Jinneng Holding Equipment Manufacturing Group, has been successfully completed. The gasification framework has seven layers, with a length of 143.7 meters, a width of 13 meters, and a height of 35 meters, giving it a total construction area of 8,219 square meters. The gasification unit mainly consists of 12 φ3600 mm pure oxygen continuous gasification furnaces, frames, trestles, coal conveying belts, as well as modifications to the associated coal storage sheds and the relocation of intercoolers. The project commenced in March 2025. This project uses advanced micro-pressure fixed-bed pure oxygen oxidation technology to produce gas, eliminating pollution caused by the emission of purge air in intermittent gas production methods at the source, and effectively reducing the discharge of waste gases, wastewater, and solid waste. At the same time, this project provides a new approach for the transformation of fixed-bed batch gasification processes in local coal chemical enterprises, thereby facilitating the deeper development of the energy revolution in the surrounding areas and injecting new momentum into the high-quality development of the regional economy. As announced in December 2024, the consortium composed of China Chemical Engineering Third Construction Co., Ltd., Southwest Chemical Engineering Research and Design Institute Co., Ltd., and Henan Changyu Industrial Co., Ltd. won the bid for the design, procurement, and construction of the pure oxygen continuous gasification unit as part of the energy-saving and environmental protection improvement project at Tianyuan Shanxi Chemical Co., Ltd.; this is a turnkey EPC project. For the energy-saving and environmental-protection improvements as well as related renovations at Tianyuan Shanxi Chemical Co., Ltd., a subsidiary of Jinneng Holding Equipment Manufacturing Group, 12 DN3600 pure-oxygen continuous gasification units manufactured by Henan Changyu (11 in operation and 1 as backup) were installed, replacing the existing 28 DN2800 fixed-bed lump-coal atmospheric intermittent gasification furnaces in the plant, as well as the 4 DN2800 pure-oxygen continuous gasification units built in 2021. A new air separation unit with an oxygen production capacity of 34,000 m3/h will be installed, while the one with a capacity of 7,000 m3/h will be phased out. Compression, transformation, desulfurization, and decarburization are carried out through corresponding modifications. Project Name: Gas Production Energy Conservation, Environmental Protection Improvement and Related Renovation Project. Constructor: Tianyuan Shanxi Chemical Co., Ltd., Jineng Holding Equipment Manufacturing Group. Location of construction: Within the premises of Tianyuan Shanxi Chemical Co., Ltd., Jineng Holding Equipment Manufacturing Group. The total investment for this project is 751.998 million yuan, of which 155.58 million yuan is allocated to environmental protection measures.
