Latest Progress on Enerchemical’s 1 million tons per year methanol production capacity expansion project Author/Source: Coal Chemical Industry 114 Forum Date: June 21, 2020 Clicks: 271 On June 16, the GIS switchgear in the 110kV step-down substation for Enerchemical’s 1 million tons per year methanol production capacity expansion project passed the inspection by the Ordos Electric Power Bureau, being completed three days ahead of the scheduled timeline – marking the achievement of an important milestone in phases one and two of this project. The successful completion of the GIS installation work and its passing of the final acceptance will create favorable conditions for the power supply via the 110kV Phase II overhead lines at the main substation. It will also lay a solid foundation for supplying power to all the equipment in both Phase I and Phase II of the plant once the 110kV capacity expansion upgrades in Phase II are completed. According to the project plan, the methanol project of China Coal Hubei Energy Chemicals is expected to complete handover by the end of November 2020. The second-phase construction project of China Coal Enerchemical Company, which involves technological upgrades for the production of 1 million tons of methanol per year from syngas, is located in the Tuk Industrial Park in Ordos, Inner Mongolia. Land for this second phase has been reserved next to the facilities from the first phase, covering an area of 25.13 hectares. The project utilizes Zemach BGL fixed-bed slag gasification technology, purification technologies (low-temperature methanol washing + deep cryogenic methane separation), as well as advanced methanol synthesis technologies with low consumption and energy use, to build an MTO-grade methanol plant with an annual production capacity of 1 million tons. On September 21, 2018, the groundbreaking ceremony was held for the technical upgrade project at China Coal Ordos Energy Chemical Co., Ltd., aimed at producing 1 million tons of methanol per year from syngas. The main units include: a 1 million tons per year methanol production plant, which comprises an air separation unit, a gasification unit (for gasification, gas-water separation, phenol and ammonia recovery, coal gas compression, shift reaction and cooling, chemical deoxidation station, integrated tank area, gasification slag disposal, gasification flares, etc.), a purification unit (low-temperature methanol washing, RTO system for flue gas combustion), a cryogenic separation unit (for methane cryogenic separation, LNG tank area), a sulfur recovery unit, and a methanol synthesis unit (for syngas compression, methanol synthesis, refrigeration processes, hydrogen recovery, intermediate methanol tank area, and finished methanol tank area). The Zhongmei Energhua project, with an annual production capacity of 2 million tons of synthetic ammonia and 3.5 million tons of urea, was constructed in two phases. The first phase, which has an annual production capacity of 1 million tons of synthetic ammonia and 1.75 million tons of urea, included two 40,000 Nm3/h air separation units; these units were completed and put into operation in 2013. Meanwhile, some of the public facilities required for the second phase, as well as all the office and living facilities, have already been built. Based on the current market conditions and operational status, Phase II of the project plans to shift from producing synthetic ammonia and urea to manufacturing 1 million tons of methanol, thereby supplying MTO-grade methanol feedstock to the olefin plants of China Coal Mengda Company.
