The Anhui Carbonxin Coke Oven Gas project, undertaken under EPC contracting by Donghua Technology, successfully produced qualified methanol. Author/Source: Donghua Technology ECEC Date: 2022-04-30 Clicks: 9 On April 28th, after countless days and nights of hard work, the comprehensive utilization project for coke oven gas carried out by Donghua Technology EPC was launched successfully in its first attempt, with the entire process completed successfully and qualified methanol produced. The Anhui Carbonxin Coke Oven Gas Comprehensive Utilization Project is an important component of the rapid development of Huaibei Mining Group. It represents a crucial step for the group’s sustainable development and for increasing the added value of its industries, and it is also a key element in the creation of a million-ton capacity base for carbon-based new materials in Anhui (Huaibei) as part of the new coal chemical synthesis materials industry. The 500,000-ton methanol and 600,000-ton ethanol production projects of Anhui Carbonxin Technology Co., Ltd. involve substantial investment; they represent key projects for Huaibei Mining Group to expand its coal chemical industry chain and develop the fine chemical sector. The owner of the methanol comprehensive utilization project carried out 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 installation includes 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. 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 mentioned in Bid Section 1).
