Successful lifting of the washing tower for the purification unit at China Coal Enerchemicals – Author/Source: Coal Chemical Industry 114 Forum, Date: 2020-06-11, Clicks: 6. On June 2, good news came from the construction site managed by Saiding Engineering Company’s China Coal Tukue project team: at a height of 64 meters, the upper and middle sections of the purification unit’s washing tower (C613301A) were assembled, aligned, and welded in mid-air, marking the successful completion of the lifting work for the tallest equipment on this project. The washing tower (C613301A/B), with a height of 92.5 m, a diameter of 3.6 m, and a weight of 573.5 t, is the core equipment of the purification system. The lifting operation for this equipment falls under the category of \"sub-projects with high risks and above a certain scale\". The company’s project team brought together personnel in construction management, safety management, and quality control to work together diligently to develop a specialized construction plan. A thorough survey of the site was conducted, and adhering to the principles of reliability, safety, technical maturity, and economic Reasonableness, an 800-ton crawler crane was used as the main lifting equipment, while a 400-ton crawler crane served as an auxiliary device to assist with the lifting process. This approach enabled the successful completion of this lifting task. The successful lifting of the scrubber tower lays a solid foundation for the smooth installation of the purification equipment and the entire project. The second-phase construction project of China Coal Enerchemical Company, which involves technical upgrades to produce 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 + cryogenic methane separation), as well as advanced methanol synthesis technologies with low consumption and energy usage, to build a facility capable of producing 1 million tons per year of MTO-grade methanol. 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 (including gasification, gas-water separation, phenol and ammonia recovery, coal gas compression, shift reaction and cooling, chemical deoxidation station, integrated tank area, gasification slag disposal, and gasification flares), a purification unit (low-temperature methanol washing and RTO systems for burning off gases), a cryogenic separation unit (for methane separation at low temperatures and LNG storage tanks), a sulfur recovery unit, and a methanol synthesis unit (including syngas compression, methanol synthesis, refrigeration processes, hydrogen recovery, intermediate methanol storage areas, and finished methanol storage areas). The Zhongmei Enechemical project, with an annual production capacity of 2 million tons of 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 ammonia and 1.75 million tons of urea, includes two air separation units with a capacity of 40,000 Nm3/h each; 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 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 raw materials to the olefin plants of China Coal Mengda Company.
