Progress on the Methanol Comprehensive Utilization Project of Anhui Carbonxin Technology Co., Ltd. Author/Source: Huahua Net Coal Chemicals Date: 2022-04-28 Clicks: 16 Recently, the foundation slab for the methyl acetate hydrogenation reactor – the core component of the ethanol production unit in Anhui Carbonxin Technology Co., Ltd.’s methanol comprehensive utilization project, which was EPC-contracted by Beijing Petrochemical Engineering Co., Ltd. – was completed. It is reported that the methyl acetate hydrogenation reaction framework consists of 18 independent pile cap foundations, and it represents the first construction site for a mass concrete structure in this project. During the construction period, the project team strictly controlled the quality of each stage of work and strengthened the inspection of construction processes, ensuring the smooth pouring of the frame foundation slab. The successful pouring of this foundation slab provides a boost to the project’s goal of completing the core framework and the foundations for key equipment before the rainy season. The 500,000-ton methanol and 600,000-ton ethanol production project undertaken by Anhui Carbonxin Technology Co., Ltd. is a large-scale investment; it represents a key initiative for Huaibei Mining Group to expand its coal chemical industry chain and develop the fine chemicals 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 plant facilities include the gasification unit, purification unit, gas separation unit, ethanol production unit, as well as various supporting 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. Upon completion, it will become the world’s largest ethanol facility. Bid Section 1: EPC general contracting for the ethanol complex 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. Winner of the bid: Beijing Petrochemical Engineering Co., Ltd. Bid amount: 1,377,202,109 yuan. Bid 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 overall plant processes and utility systems, external pipelines, a gasification unit, a purification unit, gas separation units, liquid storage and transportation systems, as well as various auxiliary engineering works (other than those listed in Bid Section 1).
