Two 800,000-ton-per-year coal-to-olefins projects commenced construction in Wucaiwan, Jungdong

On March 23, an announcement was issued for the public tender for the overall design of Xinjiang Shanneng Chemical Co., Ltd.’s 800,000-ton-per-year coal-to-olefins project in Wucaiwan, Zhundong. Construction location: West side of Shenqi Road, at the entrance of Open-pit Mine No. 4 in Wucaiwan Industrial Park, Huoshao Mountain, Wucaiwan Mining Area, Jundong Economic and Technological Development Zone, Xinjiang. Construction scale and overview: This project uses coal from the Wucaiwan No. 4 open-pit mine as raw material, and produces MTO-grade methanol (an intermediate product) through coal gasification under pressure, shift reaction and heat recovery, low-temperature methanol washing, and methanol synthesis ； MTO-grade methanol is then processed through MTO and olefin separation to obtain polymer-grade ethylene and polymer-grade propylene monomers ； Polyethylene products are produced through the polymerization of ethylene ； Propylene is polymerized to produce polypropylene products. The process technology planned for the main production units of this project is close to or reaches the current international advanced level. The main process units of this project include: air separation unit, gasification unit, purification unit, methanol unit, sulfur recovery unit, MTO unit (including butane recycle), olefin separation unit, polyethylene unit, polypropylene unit, etc. The utility systems for this project include: power stations, plant-wide water supply and drainage systems (including fire protection water systems), wastewater treatment, reclaimed water reuse, concentration, evaporation, and crystallization processes, plant-wide power supply and distribution systems, plant-wide telecommunications infrastructure, external piping networks, intermediate product storage areas and vehicle loading/unloading stations for liquid materials, olefin storage areas, flare systems, underground pipeline networks, air compression stations, heat exchange stations, storage and transportation systems, as well as projects outside the factory premises. Auxiliary facilities include, but are not limited to: the overall plant layout and transportation systems, the plant’s fire protection and gas prevention systems, the central control room, the central laboratory (environmental monitoring station), the maintenance center, warehouses for hazardous chemicals, temporary storage areas for hazardous waste, temporary storage areas for miscellaneous salts, the plant’s information management system, the comprehensive office building, the cafeteria, dormitories for shift workers, the R&D center, warehouses for finished PP and PE products, as well as various temporary facilities throughout the plant. This project is constructed in integration and simultaneously with the Colorful Bay No. 4 open-pit mine. During the design phase of this project, consideration must be given to the supply of electricity, water, heating, as well as the treatment of production and domestic wastewater for the No. 4 open-pit mine. Additionally, shared use of facilities such as office buildings, dormitories, and canteens should be taken into account to achieve optimal investment efficiency.

The second phase of the Guotai Xinhua coal-based fine chemicals circular economy industrial park produces acetylene and formaldehyde using dry acetylene units and formaldehyde production units, generates hydrogen through methanol cracking, and further produces 1,4-butanediol (BDO) via the alkyne-aldehyde method. Upon completion, it will produce 100,000 tons of 1,4-butanediol (BDO) per year, with 1,200 tons of butanol as a by-product. Project location: The proposed project is located in the Western Industrial Park of Wucaiwan, within the Western Industrial Cluster Area of the Jundong Economic and Technological Development Zone in Xinjiang. It will be constructed on the vacant land reserved at the original site of the Guotai Xinhua Phase I project. The central geographic coordinates are: 89°04′8.06 East″ ； 44°42′46.93″ north latitude. Construction contents: This project will build an acetylene generation unit, a formaldehyde production unit, a 1,4-butanediol (BDO) production unit, a hydrogen production unit via formaldehyde cracking, a high-concentration salt waste incineration unit, and an evaporation crystallization unit. Additionally, auxiliary facilities such as a refrigeration station, a foam preparation station, and a heat exchange station will be constructed.

The coal resources are converted on-site, but where should the 800,000 tons of plastic particles be sent? The five Central Asian countries, right?

The mainland won’t need to import crude oil anymore

Xinjiang has a fragile ecosystem and scarce water resources; to be honest, coal chemical industries cannot be developed there. Second, China’s downstream plastic processing and consumption markets are located in the coastal and eastern regions; what competitiveness can there be by transporting products from Xinjiang?

How about transporting the crude oil there? ? ? ?

Crude oil is transported through pipelines. Moreover, what I mean is that Xinjiang cannot develop coal chemical industry.

In fact, no place is suitable for the development of heavy chemical industries, especially in coastal areas
