Wanhua Chemical Polyol Unit Capacity Expansion and Renovation Project Announcement

Recently, the draft environmental impact report of Wanhua Chemical (Yantai) Petrochemical Co., Ltd.’s polyol unit expansion and transformation project was released for public comment.

Project Overview

Project Name: Wanhua Chemical (Yantai) Petrochemical Co., Ltd. Polyol Unit Capacity Expansion and Renovation Project

Construction unit: Wanhua Chemical (Yantai) Petrochemical Co., Ltd.

Type of construction: expansion

Construction location and area: The west area of ​​Wanhua Yantai Industrial Park, Yantai Economic and Technological Development Zone, Yantai Chemical Industrial Park, is located within the boundary of the existing butanol device, and no new area will be added.

Project Overview: Capacity expansion and renovation of the polyol plant in the park. The project’s public works and auxiliary facilities rely on the existing park facilities.

Project background

The 250,000 tons/year butanol unit is one of the main process units in the propylene oxide and acrylate integrated project of Wanhua Chemical Group Co., Ltd. The project obtained environmental impact assessment approval in 2012 (Tobacco Environmental Assessment [2012]17), divided into The acceptance approval was obtained in 2016 (Yanghuanyan [2016] No. 32) and 2017 (Yanghuanyan [2017] No. 49), in 2018
Complete independent acceptance by the year.

With the continuous deepening of my country’s energy conservation, emission reduction, green and environmentally friendly economic policies and the rapid development of new material applications, neopentyl glycol (hereinafter referred to as NPG) products and trimethylolpropane (hereinafter referred to as TMP) products have become increasingly popular in the field of new materials. The scope of application will continue to expand, and the development prospects are very broad. Wanhua Yantai Industrial Park has an 80,000 tons/year neopentyl glycol unit in operation and a 60,000 tons/year neopentyl glycol project under construction. The demand for the raw material isobutyraldehyde will greatly increase. At the same time, a 50,000 tons/year trimethylolpropane project is under construction, which requires a butanol unit to provide refined n-butyraldehyde as raw material, which will partially affect the production of butanol. For this reason, in order to ensure the demand for isobutyraldehyde and n-butyraldehyde in the park’s downstream units while ensuring the production of butanol, the butanol unit needs to be expanded and transformed.

Wanhua Chemical (Yantai) Petrochemical Co., Ltd. is a wholly-owned subsidiary of Wanhua Chemical Group Co., Ltd. and was registered on April 20, 2015. The company relies on the advantages of a complete integrated industrial chain, advanced production core technology and excellent corporate management culture to provide customers with competitive products and services. The product business scope involves acrylic acid and esters, polyols, propylene oxide, methane tert-butyl ether, ethylene, PVC and other fields.
