Plant production scale

This project is Fujian Fuhua Gulei Petrochemical Co.
, Ltd.
200,000 tons of hexamethylene diamine, 300,000 tons of adipic acid and 400,000 tons of nylon 66
.

The main production units of this project include nitric acid unit, cyclohexanol unit, adipic acid unit, hexanediamine unit, methylpentanediamine unit, nylon 66 unit, as well as tank farm, refrigeration station, circulating water station, fire water system, foam Stations, sewage treatment stations, substations, comprehensive buildings and other public works and auxiliary production facilities

Product solutions

The main product plans of this project are shown in the following table:

Table List of product plans for this project

General process description

This project uses the adiponitrile produced by the butadiene process adiponitrile production technology as the raw material (the adiponitrile is the purchased raw material), and the produced adiponitrile is hydrogenated by the low-pressure hydrogenation method to produce the product that meets the downstream polymerization requirements.
Hexanediamine products
.
Cyclohexanol is produced by partial hydrogenation of benzene, followed by oxidation to produce adipic acid
.
Adipic acid and hexamethylene diamine are subjected to salt formation reaction to obtain nylon 66 salt; nylon 66 salt passes through a slicing device, is concentrated, polycondensed, diced, dried and packaged into a final nylon 66 sliced ​​product
.
The annual operating time is 8000 hours
.
Before and after the completion of the project, the process route, material flow and device matching of the whole plant are shown in the following figure:

Economic Benefit Analysis

According to the project feasibility study report, the total investment of the project is 8,362,101,600 yuan, the average annual operating income during the operation period is 8,645,921,400 yuan, the average annual total profit is 1,505,665,200 yuan, and the net profit after income tax is 1,129,248,900 yuan
.
The total investment rate of return of the project is 17.
69%, and the net profit rate of capital is 45.
01%
.
The after-tax capital investment payback period is 7 years
.
From the perspective of financial evaluation, the project is feasible and has good economic benefits
.
From the economic investment sensitivity analysis, it can be seen that the project has a strong ability to resist investment risks, so the project is feasible from the perspective of economic benefits
.

Matching with the adiponitrile project! Form a closed loop of the industrial chain

As mentioned earlier, the raw materials required for the hexamethylene diamine and nylon 66 projects in this EIA come from the company's upcoming adiponitrile project
.
It is reported that the environmental impact assessment report of another project of Fuhua Gulei Petrochemical "annual production of 400,000 tons of adiponitrile, 260,000 tons of acrylonitrile and raw materials supporting projects" has been officially approved on July 21, 2022
.

The proposed site of the project is located in Gulei Petrochemical Base, Gulei Economic Development Zone, Zhangzhou, Fujian, with a total investment of 14.
84 billion yuan.
The construction period is planned to be from December 2022 to December 2025.
Tons of acrylonitrile and raw material supporting projects provide adiponitrile, methylglutaronitrile and liquid ammonia as raw materials to produce hexamethylenediamine, methylpentamethylenediamine and nitric acid products
