The 500,000-ton methanol-to-ethanol project at Kaiyue Coal Chemicals, operated by Yanchang Petroleum, has entered the installation phase. January 8, 2025 – Recently, the steel structure for this 500,000-ton/year methanol-to-ethanol project, which is under EPC contracting by Beijing Petrochemical Engineering Co., Ltd., began to be installed, marking the transition of the project’s construction from the civil engineering phase to the installation phase. The steel structure of this project weighs over 6,500 tons, and high-strength bolts as well as welding are primarily used for its connection. During the construction period, the project team strictly adhered to the relevant requirements set by the project owner, pursued meticulous management of the project, formulated comprehensive construction plans, strictly controlled construction safety, quality, and progress, and made appropriate arrangements for human resources and equipment to ensure that the steel structure installation work progressed smoothly according to the planned schedule. The project is located in the Yuheng Coal Chemical Industrial Park in Hengshan District, Yulin City, Shaanxi Province. Since construction began in winter, in order to overcome unfavorable conditions such as strong winds and low temperatures and ensure the smooth progress of the project, the project team prepared a winter construction plan in advance and carefully planned the construction process. Before lifting, provide safety and technical instructions to the on-site workers to ensure safe lifting. The installation of the steel structure has begun, creating the prerequisites for subsequent installation work such as pipes, equipment, and cable trays. The project department will continue to optimize the construction process, coordinate resources effectively, and advance the project construction with high quality and efficiency. The site for Shaanxi Yanchang Petroleum Yulin Kaiyue Coal Chemical Co., Ltd.’s 500,000 tons per year methanol-to-ethanol project is located on the industrial land reserved within Kaiyue Coal Chemical’s existing facility, with no additional land required. The project utilizes the DMTE methanol-to-ethanol process technology developed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, which holds independent intellectual property rights. It involves upgrading existing shift and purification units, and carrying out expansion work using the excess syngas and methanol available from those units. The project construction contents mainly include: a raw material separation unit, a dimethyl ether synthesis unit, a carbonylation unit, a hydrogenation and product separation unit, tank areas and loading/unloading areas, as well as auxiliary and utility systems. In addition, sulfur warehouses, hazardous waste temporary storage facilities, and chemical storage areas will also be relocated and rebuilt. The total investment for the project is 2,634,321,800 yuan. Beijing Petrochemical Engineering Co., Ltd. is responsible for the EPC project of the main units in Section 1, which includes the ethanol plant (including the gas separation unit). Hualu Company is in charge of the EPC project for the systems in Section 2, which encompasses plant modifications, overall system installations, auxiliary production facilities, logistics facilities, and water treatment systems.
