    On May 13, Fujian Fuhua Gulei Petrochemical Co.
    , Ltd.
    (hereinafter referred to as "Fuhua Gulei Petrochemical") conducted an environmental impact on its annual production of 200,000 tons of hexamethylene diamine, 300,000 tons of adipic acid and 400,000 tons of nylon 66 The evaluation draft is published
    .
    It is reported that as early as February 26, Fuhua Gulei Petrochemical's 400,000-ton adiponitrile and 260,000-ton acrylonitrile project was accepted for environmental impact assessment, which provided raw material support for the company's nylon 66 project
    .
    So far, the scale of domestic nylon 66 industry has been expanded again.
    At the same time, Fuhua Gulei Petrochemical has formed a closed-loop industrial chain of "adiponitrile-hexanediamine-nylon 66"
    .

    Project Overview

    1.

    , Ltd.

    Construction site: In Gulei Petrochemical Base, Gulei Economic Development Zone, Zhangzhou, Fujian
    .

    Construction nature: new project

    The total investment of the project: 8362.
    1016 million yuan, the total investment in environmental protection is about 114 million yuan, accounting for 1.
    36% of the total project investment
    .

    Project area: The project covers an area of ​​74.
    1hm2 and a building area of ​​112,000m2

    Total capacity: 1158 people

    Annual operating time: 8000h, operating in four shifts

    Construction period: 2022.
    12 ~ 2025.

    Project construction progress

    The construction schedule of the project is shown in the table below
    .



    4.
    Production process

    The liquid ammonia, benzene, hydrogen and other raw materials used in this project are combined with the market and have stable sources.
    They are common chemical raw materials (with corresponding product quality indicators and inspection standards) with clear and stable physical and chemical properties and meet the requirements of clean production; adiponitrile , Methylglutaronitrile comes from Fujian Fuhua Gulei Petrochemical Co.
    , Ltd.
    with an annual output of 400,000 tons of adiponitrile, 260,000 tons of acrylonitrile and raw materials supporting projects
    .
    The raw materials realize the material circulation in the park and meet the requirements of clean production
    .

    The nitric acid unit adopts the double-pressurized ammonia oxidation process, the cyclohexanol unit adopts the cyclohexene process, the adipic acid unit adopts the nitric acid oxidation cyclohexanol method, the hexamethylene diamine unit adopts the low-pressure hydrogenation solvent method of adiponitrile, and the methyl glutaric acid The amine adopts the methylglutaronitrile hydrogenation solvent method, and the nylon 66 device adopts the continuous polymerization method, both of which are advanced domestic and foreign technological methods and meet the requirements of clean production
    .

    Engineering Features

    1.
    The construction site of this project is located in Zhangzhou Gulei Petrochemical Base.
    The project belongs to the manufacture of basic chemical raw materials and new materials, which is in line with the industrial layout and industrial positioning of the park
    .

    2.
    The steam required for this project is mainly provided by the park and self-produced
    .

    3.
    This project uses Fujian Fuhua Gulei Petrochemical Co.
    , Ltd.
    with an annual output of 400,000 tons of adiponitrile and 260,000 tons of acrylonitrile and the adiponitrile, methylglutaronitrile and liquid ammonia provided by the raw material supporting project as raw materials to produce Hexanediamine, methylpentanediamine, nitric acid products
    .

    Background of the project

    Nylon 66 is mainly used in the production of engineering plastics, fibers and advanced synthetic materials, which are widely used in industries such as electronics, automotive, aviation, transportation and consumer safety
    .
    With the rapid development of China's engineering plastics, fibers and polymer end-use industries, the market demand for nylon 66 has also risen sharply
    .
    Compared with nylon 6, nylon 66 has better crystallinity, making nylon 66 better toughness, higher melting point, lower water solubility, higher tensile strength, and better color firmness
    .
    Especially in today's automotive manufacturing, traditional steel and other metals are being replaced by polymers to improve fuel efficiency, enhance design options and reduce production costs
    .
    The benefits of nylon 66 are especially important for advanced engineering thermoplastic applications, which are also favored in many advanced industrial nylon fibers and applications for airbags and tire cords due to their high toughness and melting point
    .
    Greater stretch and improved color firmness make it a high price in the textile fiber industry
    .

    The key raw material for the production of nylon 66 is dinitrile, which has always been completely dependent on imports.
    The National Development and Reform Commission has listed the production of nylon 66 with dinitrile as a national "stuck neck" project
    .
    In February 2020, China Chemical Tianchen Qixiang 1 million tons/year nylon new material project started construction.
    The project adopts the adiponitrile technology independently developed by Tianchen to produce adiponitrile, hexamethylene diamine, nylon 66 and other products, marking the Localization of adiponitrile technology with independent property rights
    .

    In view of the above background, Fujian Fuhua Gulei Petrochemical Co.
    , Ltd.
    plans to invest 8,362,101,600 yuan.
    The total area of ​​the project is about 74.
    1hm2, and a new 400,000-ton/year nylon 66 salt-forming and slicing device, 225,000 tons/year cyclohexanol plant, 300,000 tons/year adipic acid plant, 200,000 tons/year hexamethylenediamine plant, 270,000 tons/year nitric acid plant and 66,700 tons/year methylpentanediamine plant and other supporting public and environmental protection projects
