The construction of the ethanol production unit in Anhui CarbonXin Technology Co., Ltd.’s methanol comprehensive utilization project has commenced in full. Author/Source: Huahua Network – Coal Chemical Industry. Date: February 11, 2022. Clicks: 15. On February 10, the groundbreaking ceremony for the civil engineering and pile foundation work of the ethanol production unit was held; this marked the start of full-scale construction at the site. The project is under EPC general contracting by Beijing Petrochemical Engineering Co., Ltd. The pile foundation project for the ethanol integrated plant in this project involves approximately 231 cast-in-place piles, which are located in key areas such as the framework of the carbonylation reactor, the framework of the methyl acetate reactor, and the foundations of critical equipment. The bored pile construction will last for 1 month, and the commencement of these works creates favorable conditions for the subsequent civil engineering foundation work. Beiyou Engineering Company is undertaking the EPC general contracting for the world’s largest ethanol plant under this project, with a production capacity of 600,000 tons per year. This device utilizes the extended Zhongke DMTE technology; using methanol and syngas as raw materials, it produces ethanol products with high added value through processes such as methanol dehydration, dimethyl ether carbonylation, methyl acetate hydrogenation, and separation. The 500,000-ton methanol and 600,000-ton ethanol production projects of Anhui Carbonxin Technology Co., Ltd. involve a large scale of investment; 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 utilities 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 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. 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 Section 1).
