On the 19th of the month, the list of candidates selected for the EPC contract for the high-density polyethylene production unit of Xinjiang Shanneng Chemical Co., Ltd.’s 800,000 tons per year coal-to-olefins project in Wucaiwan, Zhundong, was made public. The winning bidder for this project was CNPC Jilin Chemical Engineering Co., Ltd., with a bid amount of 915,888,856.0 yuan. For the EPC contract related to the methanol synthesis unit, the winner was China Chengda Engineering Co., Ltd., with a bid amount of 509,956,551 yuan. As for the EPC contract for the purification units, the winner was China Wuhuan Engineering Co., Ltd., with a bid amount of 750,615,818 yuan. The supplier for the carbon dioxide compression units was Shenyang Turbine Machinery Co., Ltd. For the overall EPC contract for the coal-to-olefins unit, SINOPEC Engineering Construction Co., Ltd. SEI was chosen. For the foundation design services related to hydrogen production through water electrolysis, China Wuhuan Engineering Co., Ltd. was selected. This company was also responsible for overall management and technical services, as well as the foundation design and some of the detailed designs. China Tianchen Engineering Co., Ltd. was responsible for the foundation design of the purification units (low-temperature methanol washing, refrigeration, CCUS, sulfur recovery), as well as the foundation design of the methanol synthesis unit. China Wuhuan Engineering Co., Ltd. handled the foundation design of the air separation, gasification, and conversion units, while China Tianchen Engineering Co., Ltd. was responsible for the foundation design of the polypropylene production unit. Daqing Petrochemical Engineering Co., Ltd. provided air separation technology, process packages, and complete sets of equipment. CNPC Jilin Chemical Engineering Co., Ltd. supplied the methanol synthesis technology and related process packages. The total investment in Shandong Energy’s Xinjiang Energy Chemical Integration Project in Zhundong is 33.8 billion yuan. This project includes four sub-projects: an annual production capacity of 800,000 tons of coal-to-olefins, the first phase of the No. 4 open-pit mine in the Wucaiwan mining area with an annual production capacity of 23 million tons, a dedicated railway line for this project, and a living facility for the workers involved in this project. The first-phase project of Open Pit No. 4 in the Wucaiwan mining area in Zhundong covers an area of 96.88 square kilometers. The designed recoverable amount of raw coal is 2.958 billion tons, with an annual production capacity of 23 million tons per year, and a designed service life of 128.6 years. The Shandong Energy Yankuang Xinjiang Energy Chemicals Zhundong Coal Chemical Integration Railway Dedicated Line project is a dedicated transportation railway to support the No. 4 open-pit coal mine and the 800,000 tons per year coal-to-olefins project; it is designed as a single-track railway. The line connects to the Zhundong Station of the Wujiang Railway and leads to the newly built Shanneng Chemical Industry Station. It is 24.37 kilometers long, with a designed speed of 80 kilometers per hour and a designed transport capacity of 35 million tons per year. The 800,000 tons per year coal-to-olefins project of Xinjiang Shanneng Chemical Co., Ltd. in Wucaiwan, Zhundong, has a total investment of 20.858 billion yuan. It is located in the Huoshao Mountain Industrial Park within the Wucaiwan mining area of the Zhundong Economic and Technological Development Zone in Xinjiang. The project uses coal as raw material; through gasification, purification, and synthesis, MT0-grade methanol is produced. MT0 technology is then employed to manufacture polymeric-grade ethylene and propylene monomers, which are further processed via polymerization to produce high-density polyethylene, polypropylene products, and other by-products. The construction scope includes air separation units, gasification units, purification units (reformation, low-temperature methanol washing and cryogenic treatment, CCUS, sulfur recovery), methanol synthesis units, methanol-to-olefins units (MTO, olefin separation, steam cracking, butene-1 and other units), polyethylene plants, polypropylene plants, hydrogen production facilities via water electrolysis, as well as the associated utility systems and auxiliary facilities. Sinopec Engineering Construction Co., Ltd. is responsible for the EPC general contracting of the methanol-to-olefins plants (MTO, olefin separation, butene-1, and steam cracking).
