Thread Content
Recently, the Ecology and Environment Bureau of the Management Committee of the Ningdong Energy and Chemical Industry Base in Ningxia issued a public notice regarding the acceptance of the environmental impact assessment documents for the second-phase polyoxymethylene project of Ningxia Coal Industry Co., Ltd., which is part of the Energy Group. Project OverviewProject Name: **Phase II Polyoxymethylene Project of Ningxia Coal Industry Co., Ltd., Energy Group**
Project Nature: Renovation and expansion
Construction Scale: Construction of a new polyoxymethylene production facility with an annual capacity of 60,000 tons, comprising a ferro-molybdenum method for formaldehyde synthesis, a dioxolane (DOX) unit, a trioxymethylene (TOX) synthesis unit, as well as polymerization and post-treatment units.
Industry Category: According to the “National Economic Industry Classification” (GB/T 4754-2017, revised edition 2019), this project falls under category 2651, which pertains to the manufacturing of primary plastic forms and synthetic resins, within the industry of chemical raw materials and chemicals (C26) ； According to the \"List of Categories for Environmental Impact Assessment of Construction Projects\" (2021 edition), this project falls under the category of \"Synthetic Material Manufacturing\" within the section \"23. Chemical Raw Materials and Chemical Products Manufacturing\". Location: The project will be constructed in Area A of the Coal Chemical Industry Park in the Ningdong Energy and Chemical Industry Base. To the west of the proposed site lies a already-operational polyoxymethylene plant from the first phase of construction; to the north is another plant for producing olefins from methanol; to the east is reserved land; and to the south are the railway lines and coal handling facilities of the base. Land area: The site for this project is roughly rectangular, with a length of about 450 meters from east to west and a width of about 250 meters from north to south (based on the centerline of the surrounding walls). The total area covered by the site is approximately 11.35 hectares, and it is designated as industrial land. Construction contents: This project consists mainly of the main structure, utility systems, auxiliary facilities, storage and transportation systems, environmental protection measures, as well as other supporting structures. The main processes include the ferro-molybdenum method for formaldehyde synthesis, the dioxolane (DOX) unit, the trioxane (TOX) synthesis unit, as well as the polymerization and post-treatment units ； Public utilities mainly include production and fire-fighting water pressure stations, circulating water systems, accident water tanks, desalination stations, sewage treatment plants, heating systems, and central control rooms ； Auxiliary facilities include heat exchange stations, etc ； Storage and transportation engineering includes raw material storage tanks, product warehouses, etc. Among these, air separation and air compression, circulating cooling water, desalinated water, heating services, and laboratories all make use of the existing public facilities of Ningxia Coal Group. The investment in projects and environmental protection measures amounts to 1,560.9 million yuan in total, with 109.11 million yuan allocated to environmental protection efforts, accounting for 7.0% of the total investment. The number of employees required for this project is 165 additional persons
The first phase of Ningxia Coal’s 60,000-ton polyoxymethylene production project was built over a decade ago, making it one of the earliest such projects in China; the second phase doubled the production capacity, which shows that polyoxymethylene is a profitable business.
