Author/Source: Donghua Technology ECEC. Date: 2022-11-12. Clicks: 20. Recently, the civil engineering and safety work for the dimethyl ether tank area, methyl acetate tank area, and ethanol tank area as part of Anhui CarbonXin Technology’s methanol comprehensive utilization project, which was overseen by Donghua Technology, was completed. To date, all tank areas of this project have completed their safety handover in one go, laying the foundation for the subsequent installation work. The dimethyl ether storage area, methyl acetate storage area, and ethanol storage area cover an area of over 20,000 square meters. Among them, the two dimethyl ether spherical storage tanks in the dimethyl ether tank area are classified as A3 type pressure vessels; their installation is complex, high technical and quality standards are required, and there are numerous inspection items. The civil engineering work was completed on schedule, creating favorable conditions for the project to overcome construction technical challenges and fulfill its construction tasks with both quality and quantity ensured. The 500,000-ton methanol and 600,000-ton ethanol production projects of Anhui Carbonxin Technology Co., Ltd. involve a large investment scale; they represent key projects for HuaiBei Mining Group to extend its coal chemical industry chain and develop the fine chemical sector. The owner of the methanol comprehensive utilization project undertaken by Anhui Carbonxin Technology Co., Ltd. is Huaibei Mining Co., Ltd. The project uses methanol from Anhui Carbonxin Technology Co., Ltd.’s existing methanol production facility as raw material; it is combined with a powder gasification unit to produce syngas, from which CO and H2 are separated. Through carbonylation and hydrogenation reactions, an ethanol production capacity of 600,000 tons per year is achieved. The project facilities include the gasification unit, purification unit, gas separation unit, ethanol production unit, as well as various supporting infrastructure and auxiliary systems required to carry out the project’s processes. The ethanol production unit of this project utilizes the extended Zhongke DMTE technology; using methanol and syngas as raw materials, it goes through processes such as methanol dehydration, dimethyl ether carbonylation, methyl acetate hydrogenation, and separation, to produce 600,000 tons of ethanol per year. Once completed, it will become the world’s largest ethanol facility. Section 1: EPC general contracting for the ethanol complex PC project. The ethanol complex includes: a dimethyl ether synthesis unit, a carbonylation unit, hydrogenation and separation units, a compression unit, a heating furnace unit, a refrigeration station, the on-site cabinet room for the ethanol plant, a 35kV substation for the ethanol plant, a catalyst regeneration unit, tanks for initial rainwater and production wastewater, as well as fire protection facilities. Section 2: EPC general contracting for the comprehensive utilization project of methanol, covering the works other than those in the ethanol complex. This includes: the entire plant’s process and utility systems, external pipelines, a gasification unit, purification units, gas separation units, liquid storage and transportation systems, as well as various auxiliary and supporting engineering works (other than those in Section 1).
