At the end of June, in the Zhundong Gobi Desert, the rolling heat wave could not stop the footsteps of the builders. With the fluttering of colorful flags and the firing of salute cannons, the Xinjiang Shanneng Chemical Industry Zhundong Wucaiwan 800000 tons/year coal to olefin project -450000 tons/year polypropylene plant, jointly contracted by Jilin Chemical Construction Company and Daqing Petrochemical Engineering Co., Ltd., has officially started construction. This is another key milestone for this mega modern coal chemical project, following the successive start-up of methanol to olefins, gasification, and air separation units. As an important puzzle in the 33.8 billion yuan integrated coal chemical project of Shandong Energy, Xinjiang Energy, and Zhundong Coal Chemical, this super project located at the mouth of the No. 4 open-pit mine in Wucaiwan is gradually moving from blueprint to reality.

Process and Supporting Equipment of Polypropylene Plant

The 450000 tons/year polypropylene plant that started construction this time covers key areas such as triethylaluminum treatment and oil storage area, polymerization area, granulation area, and pellet mixing area, and is the core carrier to ensure stable and efficient production of polypropylene products. The auxiliary facilities include the installation substation, cabinet room, rain shower valve room, installation pipe gallery, water supply and drainage and underground pipe network, power supply and lighting, telecommunications system, overall transportation and sewage collection, and other supporting projects, covering the entire process of production and operation, safety guarantee and environmental protection control, providing support for the standardization, normalization, green construction and long-term stable operation of the installation.

Overview of Coal to Olefins Project

The 800000 tons/year coal to olefin project of Xinjiang Shanneng Chemical Co., Ltd. in Zhundong Wucaiwan is located in the modern coal chemical industry demonstration zone of Zhundong Economic and Technological Development Zone, Xinjiang (west of Shenqi Road, Wucaiwan No. 4 open-pit mine mouth, Huoshaoshan Industrial Park, Wucaiwan Mining Area). The total investment of the project is 20858011900 yuan, of which the environmental protection investment is 1.667 billion yuan, accounting for 8.0% of the project construction investment. The construction content includes main engineering, storage and transportation engineering, public engineering, environmental protection engineering and supporting engineering. The main construction includes 13 sets of production facilities, including 3 × 75000Nm ³/h oxygen air separation (2 steam driven and 1 electric driven), 2.2 million t/a methanol plant (including gasification, transformation, heat recovery and purification of 657000 Nm ³/h effective gas, 20000 t/a sulfur recovery), 2.2 million t/a methanol to olefin plant, 800000 t/a olefin separation plant, 50000 t/a steam cracking plant, 15000 t/a C4 to 1-butene plant, 450000 t/a polypropylene plant, 450000 t/a polyethylene plant, etc.keywords:Domestic new energy latest news

Zhundong Coal Chemical Integration Layout

The total investment of Shandong Energy Xinjiang Energy and Chemical Zhundong Coal Chemical Integration Project is 33.8 billion yuan, consisting of four sub projects: an annual production of 800000 tons of coal to olefin project, an annual production of 23 million tons of Wucaiwan mining area No. 4 open-pit mine phase I project (with a mining area of 96.88 square kilometers, a designed coal mining capacity of 2.958 billion tons, and a designed service life of 128.6 years), Zhundong Coal Chemical Integration Railway Special Line (connecting from Zhundong Station of Wujiang Railway to the newly-built Shanneng Chemical Station, with a total length of 24.37 kilometers, a designed speed of 80 kilometers per hour, and a transportation capacity of 35 million tons per year), and Zhundong Coal Chemical Integration Life Center. The project aims to build an integrated pattern of coal, chemical, transportation, and service, promote the clean and efficient utilization of local coal, and deeply transform it into high value-added materials.Editor/Yang Meiling
