Progress on the Construction of Anhui Carbonxin Technology’s Methanol Comprehensive Utilization Project Author/Source: Huahua Net Coal Chemicals Date: 2022-03-28 Clicks: 19 On March 22, after nearly 20 days of round-the-clock work, Donghua Technology completed the construction of 182 bored cast-in-place piles for the gasification unit and the black water treatment section of Anhui Carbonxin Technology’s methanol comprehensive utilization project, marking the successful completion of the pile foundation works for these two units. The gasification unit is the core equipment of the project, and its construction progress lies on the critical path of the overall project schedule; all tasks related to it are considered critical tasks. To ensure the construction progress of the gasification facility, the project team has implemented multiple contingency plans to overcome the impacts of factors such as the pandemic, and has taken thorough measures to supervise construction safety and quality, thereby ensuring the orderly progress of on-site work. 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 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 installation includes 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 plant in this project utilizes the extended DMTE technology developed by Yanchang Zhongke. Using methanol and syngas as raw materials, it produces 600,000 tons of ethanol annually through methanol dehydration, dimethyl ether carbonylation, methyl acetate hydrogenation, and separation processes. 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).
