On November 4th, the Ecology and Environment Bureau of Yulin City issued a public notice on the approval decision of the environmental impact assessment report for the construction projects of two chemical projects (300000 tons/year polyethylene, 400000 tons/year polypropylene (emergency response) project, 220000 tons/year vinyl acetate, and 200000 tons/year polyvinyl alcohol project) proposed by Shaanxi Coal Group in Yulin.

Why Yulin Chemical invested over 6 billion yuan to build temporary facilities (polyolefin plant, polyvinyl alcohol project)!

It is reported that during the implementation of the "Olefins, Aromatic Hydrocarbons, and Deep Processing Project", due to factors such as technological sources, market conditions, and financial guarantees, it is planned to implement the construction in stages, starting with the construction of coal to methanol to olefin and some downstream units (polyethylene, polypropylene, vinyl acetate, EVA, acrylic acid, and high water absorbent resin, etc.); Subsequently, other downstream facilities for olefins (such as ethylene oxide, POE, propylene oxide, phenol acetone, biodegradable materials, etc.) and downstream facilities for aromatics (such as coal pyrolysis, coal tar hydrogenation, aromatics combination, polycarbonate, polyester, etc.) will be constructed in an orderly manner.

Due to the inconsistent production time of the phased implementation of the equipment, the olefin unit constructed earlier had a surplus of 254000 tons/year of ethylene and 371600 tons/year of propylene during the transition period. Ethylene and propylene monomers are flammable and explosive, and can only be stored for a short period of time under low temperature or high pressure conditions. There are significant safety hazards in external sales and transportation, and nearby enterprises have stable sources of ethylene and propylene, making it impossible to sell or consume the surplus ethylene and propylene in the surrounding area. Therefore, in order to temporarily absorb surplus ethylene and propylene, Shaanxi Coal Group Yulin Chemical Co., Ltd. plans to adopt the "one head, multiple tails" construction concept, and plans to construct 300000 tons/year polyethylene, 400000 tons/year polypropylene projects, as well as 220000 tons/year vinyl acetate and 200000 tons/year polyvinyl alcohol projects during the transition period.

Project Overview

Project Name: Shaanxi Coal Group Yulin Chemical 300000 tons/year polyethylene, 400000 tons/year polypropylene (emergency response) Project Construction Location: Yushen Industrial Zone Construction Unit: Shaanxi Coal Group Yulin Chemical Co., Ltd.

China Chemical Engineering Hualu Company and Shaanxi Coal Group Yulin Chemical Company signed an EPC general contract for the first phase of the second phase of the 15 million tons/year coal quality clean and efficient conversion demonstration project, including the air separation unit, methanol distillation unit, and polypropylene unit.

The Shaanxi Coal Yulin Chemical Project, as a key modern coal chemical demonstration project supported by the national "14th Five Year Plan", is one of the largest single investment and most technologically integrated coal chemical projects in the world. It shoulders the strategic mission of promoting the transformation of coal from "fuel" to "raw material" and "material". The first phase of the second phase of the project will construct a complete industrial chain including air separation, methanol synthesis, methanol to olefins, polyolefins, etc. As the lifeline of the olefin, aromatic hydrocarbon, and deep processing industry chain, the air separation unit will provide continuous and stable gas supply for downstream units after completion; The methanol distillation unit is the core supporting unit of the 5.6 million tons/year methanol synthesis unit of the project, and also the "quality control station" of the coal based new materials industry chain; As the terminal core link of the olefin deep processing industry chain, the polypropylene plant will effectively enhance China's self-sufficiency in high-performance synthetic materials and strongly support the high-quality development of strategic emerging industries such as new energy, automobiles, and healthcare.

Shaanxi Coal Group Yulin Chemical Co., Ltd.'s 15 million tons/year coal quality clean and efficient conversion demonstration project, olefin, aromatic hydrocarbon and deep processing engineering (referred to as the "Phase II project"), is based on the Phase I project. Through the integration of coal pyrolysis, coal/semi coke gasification and downstream deep processing technology systems, it further expands and extends the industrial chain, explores new paths for the coupling development of coal based olefins and coal based aromatic hydrocarbons, produces four categories of high value-added products, including high-performance materials, battery electrolyte solvents, degradable materials and special oil products, and ultimately produces chemical products such as polyolefins, polyesters, polycarbonates, polyether polyols, EVA, POE, SAP, DMC, DEC, EMC, EC, etc., realizing the high-end, diversified and low-carbon development of the coal chemical industry. The sentence is:. According to the principle of "overall planning and step-by-step implementation", the Phase II project is divided into Phase II Phase I project and subsequent projects. The total area of the Phase II Phase I project is about 9200 acres, with an estimated total investment of about 62 billion yuan. Coal gasification adopts 9 3500 ton aerospace furnaces, mainly constructing 5.6 million tons/year coal to methanol, 1.48 million tons/year methanol to olefin and downstream deep processing units, producing a total of 2.77 million tons/year of 8 types of products including polyethylene, polypropylene, EVA, SAP, etc.
