Beiyou Engineering won the bid for the EPC general contracting of Yanchang China Coal Yulin Coal-Gas Co-gasification to Produce Syngas project. 2025-09-19 On September 16, the results of the bid selection for the EPC general contracting of the technology demonstration project for coal-gas co-gasification to produce syngas by Shaanxi Yanchang China Coal Yulin Energy and Chemical Co., Ltd. were made public. Winner of the bid: Beijing Petrochemical Engineering Co., Ltd.; bid price: 31,957,350.00 yuan. Project Name: Technology Demonstration Project for Coal-Gas Co-gasification to Produce Syngas. Construction location: Within the Yueneng Chemical Plant area of the Jingbian County Economic and Technological Development Zone. Construction content and scale: This project mainly involves upgrading and modifying the existing methanol production plant, as well as adding a new natural gas transmission system. After technical upgrades to the gasification unit, coal and natural gas can be gasified in the same furnace, thereby increasing the production of syngas, boosting methanol output, and reducing CO₂ emissions. After the upgrade through coal-gas co-gasification, the production capacity of the methanol complex following this technical modification is 2.032 million tons per year. Traditional coal-based synthesis gas production requires adjusting the carbon-to-hydrogen ratio through reforming reactions due to the atomic composition of coal, which is rich in carbon and poor in hydrogen, resulting in significant carbon dioxide emissions. Natural gas contains more hydrogen and less carbon; gasifying coal together with natural gas enables complementarity between hydrocarbons and maintains elemental balance, thereby reducing carbon dioxide emissions and improving resource utilization efficiency. The Northwest Research Institute of Chemical Engineering has innovatively proposed a technical approach that involves introducing coal water slurry and natural gas together into the same gasifier through multiple nozzles, either single or multiple, in order to carry out co-gasification to produce syngas. This approach aims to further promote the efficient conversion of coal and natural gas as well as energy coupling, reduce equipment investment, enhance the operational flexibility of the equipment, and lower production costs.
