Gansu Zhongke Nengyuan Chemical (Gansu) Co., Ltd.’s 100,000-ton-per-year green methanol production project

Thread Content

On June 30, the Gansu Provincial Department of Ecology and Environment released the acceptance status of the environmental impact report of the 100,000-ton green methanol production project of Zhongke Nengyuan Chemical (Gansu) Co., Ltd. The main project of this project mainly includes electrolysis water hydrogen production device, air separation oxygen production device, biomass gasification device, crude syngas purification device and PSA decarbonization device, methanol synthesis and distillation device, and auxiliary projects include biomass boiler room, machine repair shop, torch, comprehensive building, etc. ； Storage and transportation systems include biomass warehouses, methanol tank areas, hydrogen tank areas, etc. ； Public works include water supply and drainage systems, desalted water stations, laboratories, etc. ； Environmental protection projects include sewage treatment stations, general solid waste temporary storage, hazardous waste storage, etc. The biomass gasification technology of this project adopts the multi-oxygen combustion carbon dioxide biomass gasification technology of Beijing Kaimingyang Thermal Energy Technology Co., Ltd. The core of multi-oxygen combustion technology is to use pure oxygen as the combustion medium, which undergoes a strong oxidation reaction with the fuel to release heat. The flue gas produced by combustion is mainly composed of high-purity carbon dioxide gas, and the recovered carbon dioxide gas can be comprehensively utilized.
