Wanhua Chemical has three more projects

Recently, Wanhua Chemical published draft environmental impact statements for the three projects on its official website. The three projects are respectively Wanhua Chemical (Penglai) Co., LTD. 's fragrance enhancer project with an annual output of 0.42 million tons, Wanhua Chemical (Yantai) Petrochemical Co., LTD.' s ethylene polyvinyl chloride production line technical transformation project and Wanhua Chemical Group Co., LTD. 's 360,000 tons of propylene oxide and ethylene oxide derivatives expansion project.

01     An annual output of 0.42 million tons of deodorant project

It is reported that the aroma enhancer is β-ionone, its molecular formula is C13H20O, is the raw material for the production of W ester. In May this year, Wanhua Chemical announced its nutrition project, and the product of the nutrition project is W ester.

According to reports, W ester is widely used in animal feed, nutritional supplements and food processing industry, is a human and animal life activities must maintain nutrients, irreplaceable, is a "million years of products", its demand is long-term stable.

As a big feed consumption and production country, there is a huge demand for W ester. With the improvement of living and consumption level in China, the demand for nutritional fortification agent represented by W ester is increasing day by day.

Due to the high technical threshold of W ester production, there have been no new entrants in the past 15 years. At the current growth rate, the existing capacity will not be able to meet the consumer demand in 10 years. In view of the high added value of W ester products and its application in animal feed, food processing, nutrition and health, as well as the high technical threshold of W ester synthesis process, the development of complete technology is of great significance.

After the future Wanhua Chemical Fragrance enhancer project is put into operation, the industrialization of W ester products can be realized, which can not only give play to the industrial chain advantages of enterprises, improve the added value of products, enhance the competitiveness and influence of enterprises in the industry, and further improve the market resistance of enterprises.

02        Technical renovation project of vinyl chloride production line by ethylene process

It is reported that the polyvinyl chloride unit is an important chlorine-consuming process production unit in the ethylene project. It is used to consume the hydrogen chloride gas produced by the TDI unit built in Wanhua Yantai Industrial Park, reduce the waste hydrochloric acid production in the park, and alleviate the market pressure and environmental pressure brought by hydrochloric acid.

The main contents of the technical transformation project are as follows:

Two oxygen chlorination reactors were replaced in the VCM (vinyl chloride) process, and the VCM capacity increased from 400,000 tons/year to 480,000 tons/year. The PVC (polyvinyl chloride) process adds 2 polymerization reactors, 2 centrifuges and 1 set of cold desalinated water deoxidation system, PVC production capacity remains unchanged at 400,000 tons/year, PVC product quality is improved; Build supporting VCM loading and EDC loading facilities.

After the transformation, the VCM process capacity of Wanhua Chemical Yantai Base has reached 480,000 tons/year, which is more conducive to the balance of hydrogen chloride capacity of the park; The production capacity of PVC process remains unchanged, and the quality of PVC products is improved, with high quality PVC reaching 400,000 tons/year.

The project will begin construction in November 2022 and be up and running in December 2023, according to the report.

03       An annual output of 360,000 tons of propylene oxide ethylene oxide derivatives expansion project

Wanhua Chemical in the field of combined polyether has a significant scientific research, technical advantages and rich production and sales experience. With the increasing concentration of the industry, it fully relies on the upstream and downstream industrial chain resources of the company, plays the strategic synergy with MDI and TDI, and is committed to becoming the leading enterprise in the global polyether industry by 2025.

At the same time, downstream customers expect Wanhua Chemical to provide more customized services in niche areas such as differentiated polyether and differentiated EOD. In order to meet customer demand and actively assume social responsibility, Wanhua Chemical plans to build an annual output of 360,000 tons of propylene oxide ethylene oxide derivatives expansion project.

It is reported that the project is an expansion project, is in the full digestion and absorption of domestic and foreign technology on the basis of polyether existing plant operation experience as the support, the development of advanced technology, product varieties, good quality, has a good market adaptability. The expansion of the project will further expand the market share of Wanhua polyether, enhance the brand image of Wanhua and the discourse power in the polyether polyol industry, lead the long-term and stable development of the industry, and create a new brand of Wanhua in the polyurethane industry.
