On April 1, the last turbine unit in the air separation system of Zhong’an United Coal Chemical Co., Ltd.’s 1.7 million tons/year coal-to-methanol and olefins production project was lifted into place at Site 3; with this, all large-scale equipment for the three air separation systems has been installed. The heavy-lifting equipment for air separation units includes three sets of air separation molecular sieve adsorbers, the crude argon column and the refined argon column inside the cryogenic box, the air cooling tower, as well as the turbine, steam turbine, air compressor, surface cooler in the compressor building, and a backup system in the form of a 200 m3 liquid nitrogen storage tank; in total, there are 28 pieces of equipment. During the installation of the air separation equipment, Sinopec Nanjing Engineering Company, which is responsible for the EPC of the project, held several specialized meetings to discuss issues such as the timing of equipment delivery and the location where it would be placed, the sequence of delivery, ground preparation, crane placement, and lifting plans. By formulating appropriate lifting plans, it was ensured that the lifting operations proceeded in an orderly manner, thus laying a solid foundation for the air separation unit to be delivered on schedule. The 1.7 million tons per year coal-to-methanol and converted olefins project of Zhongan United Coal Industry & Chemical Co., Ltd. has set the date of boiler ignition for August 30, 2018. With the construction goal of \"working hard for 100 days to ensure completion by August 30,\" the various EPC contractors involved in the project have made thorough plans, mobilized their efforts, established measures, and ensured proper implementation, thus sparking a new wave of activity in the project’s construction. The 1.7 million tons per year coal-to-methanol and converted olefins project of Zhongan United Coal Chemical Co., Ltd. is a key construction project of Sinopec and Anhui Province. The core process of the project utilizes S-MTO patented technology owned by Sinopec, while the gasification unit employs SE-Dongfang furnace technology also owned by Sinopec. Using coal from the Zhujixi mine as raw material, methanol and converted olefins (LDPE/PP), ethylene glycol (MEG) and other products are produced. Sinopec Engineering Construction Co., Ltd. is responsible for the overall management of the design, procurement, and construction of the MTO/OCC and PP units in this project, as well as six supporting facilities including the control room and 110 kV substation ； Sinopec Ningbo Engineering Co., Ltd. is responsible for the design and construction of the gasification unit for the contracted project. Zhongan United Coal & Chemical Co., Ltd. was established on December 18, 2010, with a registered capital of 4 billion yuan. It is funded equally, at 50% each, by Sinopec Corporation and Anhui Wanbei Coal and Electricity Group Co., Ltd. On December 7, 2016, a preparatory meeting was held for the resumption of work on the Zhong’an coal chemical project, to arrange the preparations for its restart. In January 2017, a meeting on resuming work on the Zhong’an project was held in Huainan. The project headquarters issued the \"Notice on Resuming Construction of the Zhong’an United Coal Chemical Project\" (Petrochemical Shares Construction & Refining [2017] No. 6), announcing that work on the Zhong’an United Coal Chemical Project would officially resume.
