Review Completed for the Purification/Synthesis Design of Anhui’s 1.7 Million Tonnes Per Year Coal-to-Olefins Project Author/Source: Date: 2017-10-26 Clicks: 80 Recently, an expert review meeting on the detailed design of the purification and synthesis units for China Anhui United Coal Chemical Co., Ltd.’s 1.7 million tonnes per year coal-to-methanol and olefins conversion project was held in Nanjing. Shi Huabiao, vice chairman and general manager of Zhongan United, and Chen Dexing, deputy general manager of Nanjing Engineering Company, attended the first meeting. The conference also invited relevant experts from Ningxia Baofeng, Zhongtian Hechuang, Sinopec Ningbo Engineering Company, and Great Wall Energy Chemicals to attend. The methanol synthesis and sulfur recovery units were constructed by Sinopec Nanjing Engineering Company, and they are an important part of the entire coal chemical project. Among them, the methanol synthesis unit has a production capacity of 1.8 million tons per year, and the unit is located on the west side of the first circulating water plant ； The sulfur recovery unit has a production capacity of 20,000 tons per year; it is located to the west of the purification unit and to the north of the methanol synthesis unit. Completion of construction is scheduled for October 30, 2018. On October 18, construction of the desulfurization unit at the power center of the Zhongan United Coal Chemical Project began. Shi Huabiao introduced the progress plan for the Zhongan United project as well as the challenges associated with it, emphasizing the need to address these issues during the review process, so as to ensure inherent safety in the design and a smooth commissioning of the project. During the meeting, Sinopec Nanjing Engineering Company reported on the progress of the detailed design and procurement work for the EPC project, as well as the issues that needed to be addressed through coordination ； The experts carefully reviewed the detailed design documents for the process, equipment, and instrumentation fields, and proposed a total of 59 suggestions for improvements and optimizations. It is reported that the construction of the Zhong’an United project is now at a critical stage, requiring simultaneous efforts in both project construction and production preparation. The goal is to have the facility completed by the end of 2018, with the entire production process up and running by June 2019. By drawing on the experiences and lessons gained from the commissioning and operation of similar coal chemical facilities operated by companies such as Zhongtian Hechuang and Ningxia Nenghua, high standards will be maintained to ensure that the facility is delivered and put into operation with high quality. The Zhong’an United Coal Chemical Integration Project is a key construction project of Sinopec and Anhui Province. 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. On January 20, 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 and Refining [2017] No. 6), announcing that work on the Zhong’an United Coal Chemical Project would officially resume. The core process of the Zhong’an United Coal Chemical Integration Project utilizes the S-MTO patent technology owned by Sinopec, while the gasification unit employs the 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.
