According to news from Jinneng Holding in mid-December, Tianyuan Company is actively carrying out tasks such as the relocation of the areas involved in gas production and air separation processes, as well as the demolition work related to the upgrade project for pure oxygen oxidation. At present, the demolition of the air separation unit has been fully completed, and ground crushing as well as waste removal work are underway ； In the gasification construction area, the work of removing equipment and pipelines surrounding the gas generation circulating water, as well as transporting out the sludge, has been completed; furthermore, the pool walls and bottom have been demolished by breaking them down. Tianyuan Shanxi Chemical Co., Ltd., which is part of Jinneng Holding Equipment Manufacturing Group, plans to install 12 new DN3600 pure-oxygen continuous gasification units (11 in operation and 1 as a backup) to improve energy efficiency and environmental performance, as well as to carry out related renovations. These new units will replace 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 that were installed in 2021. A new air separation unit with an oxygen production capacity of 34,000 m3/h will be installed, while the unit with a capacity of 7,000 m3/h will be phased out. Compression, transformation, desulfurization, and decarburization are carried out through corresponding modifications. As announced on the National Public Resources Trading Platform (Shanxi Province) in December 2024, a consortium composed of China Chemical Engineering Third Construction Co., Ltd., Southwest Chemical Industry 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 project was carried out under an EPC turnkey contract.
