Latest Progress on the Coal Chemicals Project of Shaanxi Yueneng Chemical Materials Author/Source: Refining and Chemical Industry Updates Date: 2020-07-26 Clicks: 66 To achieve the annual construction goal of reaching the zero-meter mark for the main facilities of the ethylene glycol project, Shaanxi Yueneng Chemical Materials Co., Ltd. is making every effort to accelerate various tasks. To date, 44 tendering projects have been completed, with a total tender value of 1.27 billion yuan. On July 24, a review meeting for the energy-saving report of the chemical materials company was held in Xi’an. After careful discussion and review, the participants unanimously agreed that the energy-saving report submitted by the chemical materials company complies with relevant laws, regulations, and planning requirements, and thus passed the evaluation successfully. On July 22, the Environmental Impact Assessment Report for the first phase of the project at Shaanxi Yulin Energy Group Co., Ltd., which involves the production of 1.2 million tons per year of ethylene glycol and 400,000 tons per year of ethylene glycol, along with the construction of an 110 KV substation, was successfully approved by the relevant authorities. On July 15, the bidding for the pile foundation project of the ethylene glycol facility at Shaanxi Yueneng Chemical Materials Co., Ltd. was held at the Yulin Public Resources Trading Center. The selection of the contractor for this pile foundation project marks the official start of the civil engineering work for the entire plant. From July 14th to 15th, a detailed design review meeting for the hydrogenation reactor and coupling reactor of the ethylene glycol plant was held in Chengdu. The holding of this meeting effectively resolved the difficulties encountered in the design of the ethylene glycol reactor, optimized its structural design, and significantly advanced the progress of the long-term equipment maintenance for the company’s ethylene glycol production facility. Ningbo Zhongke Yuandong Catalytic Engineering Technology Co., Ltd., China Chengda Engineering Co., Ltd., Jiangsu Yongda Chemical Machinery Co., Ltd., along with the company’s relevant technical personnel, attended the meeting. At the meeting, Xiao Lin, the project manager of China Chengda Engineering Co., Ltd., introduced information regarding the structural design of the hydrogenation reactor and coupling reactor in the ethylene glycol production plant, as well as the principles behind ethylene glycol synthesis. Subsequently, the four parties present had thorough discussions on the design, manufacturing, and operation of the reactor in Company B’s ethylene glycol plant, and ultimately reached a consensus. From July 13 to 15, a review meeting for the 30% scale model of the gasification unit for the ethylene glycol project was held at China Tianchen Engineering Co., Ltd. in Tianjin. The successful holding of this meeting has laid a solid foundation for the rapid advancement of the detailed design of the gasification unit for the ethylene glycol project, and has created favorable conditions for the procurement of equipment for this unit as well as the construction of related infrastructure. Tianchen Design Institute and the provider of Collin process package patents were present, along with Shen Yuncheng, the company’s chief engineer, Yang Lifeng, the deputy chief engineer, and other relevant technical staff. During the meeting, the participants had in-depth exchanges, thorough discussions, and careful reviews of the preliminary detailed design PID and the 30% scale model drawings. They also examined and confirmed the layout of the equipment and main pipelines, and optimized the height of the gasification unit framework to reduce it. As of July 16, the 400,000 tons per year ethylene glycol production project in the first phase of Shaanxi Yueneng Chemical Materials Co., Ltd. has successfully completed the preliminary documentation review for the propylene compressor, carbon dioxide compressor, recycled hydrogen compressor, and coupled cycle gas compressor. Recently, the relevant parties held thorough discussions and in-depth consultations on the preliminary design documents for the five compressors, PID diagrams, delivery timelines for associated components, interface requirements, lists of documents, delivery schedules, as well as the channels for transmitting documents and information, ultimately reaching actionable consensus. The successful completion of the preliminary review for the compression unit materials means that substantial progress has been made in tasks such as the process system design for the compression units in the company’s ethylene glycol project, as well as the production and supply of related equipment. The 400,000 tons per year ethylene glycol project is one of the initial projects undertaken by Yueneng Group in the coal-based clean fuel base and high-end chemical materials base located in the Qingshui Industrial Park of the Yushen Industrial Zone. The total planned land area for this project is 1,711 mu; the investment amount is 5.86 billion yuan, with 532.6274 million yuan allocated to environmental protection measures. The construction period is 30 months, and the project is scheduled to be completed and put into operation by June 2022. Using production processes such as coal-based syngas, carbon monoxide and hydrogen are used to indirectly synthesize ethylene glycol through carbonylation, coupling, and hydrogenation; meanwhile, by-products such as dimethyl carbonate, crude ethanol, mixed alcohols, sulfur, liquid oxygen, and liquid nitrogen are produced. The main facilities include those for producing coal-based syngas, purification and separation, ethylene glycol synthesis, boiler power generation, air separation units, as well as supporting utility systems. Construction contents: include gasification units, purification units, H2/CO separation units, ethylene glycol units, etc. Utilities and supporting auxiliary facilities include: 3×350t/h high-temperature and high-pressure circulating fluidized bed boilers + 2×30MW back-pressure steam turbine generator sets, air separation units, circulating water stations, desalination stations, storage and transportation facilities, sewage treatment plants, etc. Project Overview: The proposed location for the project is the Qingshui Industrial Park within the Yushen Industrial Zone. The main construction elements include a gasification unit, purification units, H2/CO separation units, and an ethylene glycol production unit. Supporting facilities include 3×350 tons/hour high-temperature and high-pressure circulating fluidized bed boilers, 2×30MW back-pressure steam turbine generators, an air separation unit, a desalination plant, storage and transportation facilities, and a sewage treatment plant.
