The propylene industry chain is strengthened again!

On July 18, 2022, the Environmental Protection Bureau of Lianyungang Xuwei New Area plans to make an approval decision on the environmental impact assessment documents of Jiangsu Hongwei Chemical Co.
, Ltd.
(hereinafter referred to as "Jiangsu Hongwei") POSM and polyol projects
.

The total investment of the project is 6.
034 billion yuan, mainly for the construction of 20/450,000 tons/year propylene oxide/styrene (POSM) and other devices.
Jiangsu Hongwei is a wholly-owned subsidiary of Shenghong Refinery (Lianyungang) Co.
,
Ltd.

The following are the main contents of the project
.

1.
Project Overview

This time, it is planned to invest in the construction of POSM and polyol projects in the Lianyungang Petrochemical Industrial Base, the National East-Central-West Regional Cooperation Demonstration Zone in Lianyungang City.
The project relies on the chemical raw materials of the refining and chemical integration project in the base to build a 508,000-ton/year ethylbenzene plant , a 20/450,000-ton/year POSM unit, a 112,500-ton/year PPG unit, and a 25,000-ton/year POP unit
.

Project name: POSM and polyol project of Jiangsu Hongwei Chemical Co.
, Ltd.

Project nature: new

Project investment: The total investment is 6.
034 billion yuan, of which the environmental protection investment is about 629 million yuan, accounting for 10.
4% of the total investment

Construction site: Petrochemical Industry Base, Xuwei New District, Lianyungang, south of National Highway 228, west of Suhai Road, north of Xi'an Road

Number of employees: 201 employees

Working hours: production in four shifts and three operations, 24 hours a day, 333 days of production per year, total annual production time of 8000h

Construction time: 36 months

Main project: including 508,000 tons/year ethylbenzene (EB) unit, 200,000/450,000 tons/year propylene oxide/styrene (POSM) unit, 112,500 tons/year polyether polyol (PPG) unit, 25,000 tons/year For the ton/year polymer polyol (POP) plant, the main project and product plan of the proposed project are shown in the table below

Project Features

The proposed project uses the ethylene, propylene and benzene of the Shenghong refining and chemical integration project for deep processing, produces propylene oxide and styrene through co-oxidation method, and further produces polyether polyol and polymer polyol products, extending the refining and chemical industry chain , in line with the needs of the development of the industrial chain of the Lianyungang Petrochemical Industrial Base
.

After the implementation of this project, Dongfang Shenghong will form the "propylene-acrylonitrile" propylene industry chain of Sierbang Petrochemical, the "propylene-phenol/acetone" industry chain of Shenghong Refinery + "propylene-propylene oxide- Polyether polyol" propylene industry chain
