It will be more lively with everyone's participation, and the sea will be more exciting with you. Everyone is welcome to participate in the forum to exchange and discuss, and pay attention to fire prevention in July.------------------------------------------------ Zhongtian Hechuang is located in Ordos, which is rich in coal resources. When it was put into operation in 2017, it was the world's largest coal-to-olefins unit, with an annual output of 1.37 million tons. In the past six years, a total of 23.94 million tons of methanol products and 7.64 million tons of olefin products have been produced, achieving good economic benefits. At 2:50 a.m. on August 17, 2017, the MTO first-line device was successfully put into operation and produced qualified ethylene and propylene products. This marked that the second series of device processes were all completed, and Zhongtian Hechuang Chemical Branch entered the fast lane of full production. It is reported that during this driving process, the routine of driving in the order of the process was broken, and the driving method was adopted. The tubular polyethylene device and the kettle polyethylene device were handed over and the other set was opened if the driving conditions were met. On April 27, 2017, the tubular polyethylene unit achieved one-time feed start-up. On August 6, 2017, the kettle-type polyethylene unit achieved one-time feed start-up. At 12:56 on August 16, 2017, the MTO first-line device was successfully put into methanol. At 20:25 on August 16, 2017, the cold separation unit of the olefin separation unit produced qualified ethylene products. At 2:50 on August 17, 2017, the thermal separation unit produced qualified propylene products.

Zhongtian Hechuang Ordos Coal Deep Processing Demonstration Project Introduction Zhongtian Hechuang Energy Co., Ltd. Coal Deep Processing Demonstration Project is located in Tuke Industrial Park, Wushen Banner, Ordos, Inner Mongolia. The project is constructed in two phases. The first phase of the project mainly constructs the Cucurbitacin mine with an annual coal output of 13 million tons, the Menkeqing mine with an annual coal output of 12 million tons, and supporting coal preparation plants. The methanol unit with an annual output of 3.6 million tons and supporting self-contained thermal power stations and other auxiliary facilities have a total investment of 44 billion yuan, of which 32.886 billion yuan is invested in coal-to-methanol and 10.7 billion yuan is invested in coal mines. The second phase of the project will construct a 2×1.8 million tons/year (feed) methanol-to-olefins (MTO) unit and a supporting 200,000 tons/year olefin catalytic cracking to propylene unit (OCC), 120,000 tons/year kettle-type low-density polyethylene ((LDPE)), 250,000 tons/year Tubular process LDPE, 300,000 tons/year gas phase linear low density polyethylene (LLDPE), 350,000 tons/year ring-pipe process polypropylene (PP), 350,000 tons/year gas phase PP, 10,000 tons/year MTBE and 30,000 tons/year butene-1 and other devices. The total project investment is 14.97 billion yuan, of which environmental protection investment is 300.77 million yuan. The project introduces GE's coal-water slurry gasification technology, Linde's methanol washing and purification technology, and Lurgi's methanol synthesis technology. The methanol-to-olefins unit adopts SMTO technology jointly developed by Sinopec Refining Engineering and China Petroleum & Chemical Corporation.
Sinopec Refinery Engineering (SEG) is responsible for the overall design of the project, which mainly includes production units such as coal gasification, purification, methanol synthesis, methanol to olefins, and polyolefins, as well as supporting public works such as air separation, power boilers, circulating water fields, and tank farms. Sinopec Ningbo Engineering Co., Ltd. (SNEC) is the master institute and is mainly responsible for the coal-to-methanol part, Sinopec Engineering and Construction Co., Ltd. (SEI) is responsible for the olefin part, and Sinopec Shanghai Engineering Co., Ltd. (SSEC) is responsible for three sets of polyolefins. On August 19, 2013, the Inner Mongolia Development and Reform Commission officially issued the "Notice of the Development and Reform Commission of the Inner Mongolia Autonomous Region on the Approval of the 3.6 million tons methanol project in the first phase of the Zhongtian Hechuang Ordos Coal Deep Processing Demonstration Project" (Neifagaiyezi [2013] No. 1851). The "Notice" agrees in principle to approve the relevant construction content of the first phase of the Zhongtian Hechuang Ordos Coal Deep Processing Demonstration Project. On March 16, 2014, the project’s coal gasification unit started construction. On June 30, 2016, all the olefin area units of the olefin project constructed by Sinopec Engineering and Construction Company were handed over to China. Zhongtian Hechuang was established in 2007 and is invested and constructed by four shareholders: China Coal Energy Co., Ltd., China Petrochemical Corporation, Shanghai Shenergy Co., Ltd., and Inner Mongolia Manshi Coal Co., Ltd. The equity ratios are 38.75%, 38.75%, 12.5%, and 10%.
Zhongtian Hechuang supporting project starts! In June 2023, Sinopec Inner Mongolia Green Hydrogen Company decided to invest 2,588 million yuan to build the "Ordos Wushen Banner Landscape and Solar Integrated Green Hydrogen Chemical Demonstration Project." This project is a joint project of a water electrolysis hydrogen production project and a wind and photovoltaic power station. By building a wind power photovoltaic section in the middle of Wushenzhao Town, Wushen Banner, the electricity generated is used for water electrolysis hydrogen production, and all the hydrogen produced by water electrolysis hydrogen production is supplied to the Zhongtian Hechuang project as an intermediate production raw material.
