Wanhua Chemical Will Launch Two New Projects and Increase the Layout of New Materials!

ECHEMI 2022-06-10

On June 6, Wanhua Chemical announced on its official website the draft environmental impact reports of two projects, one for the special isocyanate project and the other for the project with an annual output of 30,000 tons of emollients.

Special Isocyanate Project

Project Name: Special Isocyanate Project of Wanhua Chemical Group Co., Ltd.

Project site: Wanhua Yantai Industrial Park, Yantai Chemical Industrial Park, Economic and Technological Development Zone, Yantai City, Shandong Province

Project Overview: The main production units of this project include HMDA/BAC units (HMDA and 1,3-BAC can be switched for production), XDI/H6XDI units (XDI and H6XDI can be switched between production), HMDI Phase II units and For the exhaust gas decomposition and absorption device, the corresponding public works, auxiliary works, storage and transportation works and environmental protection works are built.

HMDA is hexamethylene diamine. In addition to reacting with adipic acid to synthesize nylon 66, hexamethylene diamine can also be used as an intermediate to synthesize HDI;

1,3-BAC is 1,3-cyclohexanedimethylamine;

XDI is m-xylylene isocyanate, which is an ADI (aliphatic isocyanate) containing a benzene ring;

H6XDI is hydrogenated xylylene diisocyanate, which belongs to a kind of ADI;

HMDI is 4,4′-dicyclohexylmethane diisocyanate.

Project with an annual output of 30,000 tons of emollients

Project name: Wanhua Chemical (Penglai) Co., Ltd. project with an annual output of 30,000 tons of emollients

Project site: Penglai Chemical Industry Park, Beigou Town, Penglai District, Yantai City, Shandong Province

Project Overview: This project mainly builds a 40,000-ton/year acetaldehyde plant and a 30,000-ton/year 1,3-butanediol plant, supporting auxiliary projects, storage and transportation projects, environmental protection projects, etc.; main public works And some environmental protection projects rely on existing ones.

High-performance new material integration and supporting projects

It is reported that the 30,000 tons/year emollient is part of the high-performance new material integration and supporting project of Wanhua Chemical Penglai Industrial Park.

On April 8, 2022, Wanhua Chemical announced that in order to realize the deep extension of the company’s chemical industry chain, undertake the transformation of independent research and development innovation achievements, and build a first-class integrated manufacturing base for green low-carbon high-end fine chemicals and new materials, the company plans to Through the holding subsidiary Wanhua Chemical (Penglai) Co., Ltd. to build a high-performance new material integration and supporting project in Wanhua Chemical Penglai Industrial Park.

Specifically, the planned project plans to cover an area of about 3,310 mu, mainly constructing 900,000 tons/year propane dehydrogenation, 500,000 tons/year polyether, 400,000 tons/year POCHP, 300,000 tons/year polypropylene, 300,000 tons/year polypropylene, 300,000 tons/year /year EO, 300,000 tons/year EOD, acrylic acid and ester (160,000 tons/year acrylic acid, 160,000 tons/year butyl acrylate, 20,000 tons/year octyl acrylate), 200,000 tons/year carbonate ester, 3 10,000 tons/year of emollient, air separation and other devices, as well as supporting public works and auxiliary facilities, etc.

The project plans to invest 1.5 billion yuan in 2022, which has been included in the company’s overall investment plan for 2022. The construction period of the project is planned from 2022 to 2025, and it is expected to start production in June 2024.

Wanhua Chemical actively deploys new materials

“Environmental protection is related to the living environment of human beings in the future, and the whole world is paying attention. There will be a large market for new materials and new technologies required by the environmental protection industry.” said Liao Zengtai, Secretary of the Party Committee and Chairman of Wanhua Chemical Group, in the past three years, Wanhua has invested more resources in the field of new materials.

In terms of polyurethane materials, continue to promote the upgrading of MDI technology and the stable and orderly development of the industry, expand the variety of polyurethane materials, and actively explore the market demand in new downstream areas of polyurethane, and increase the use of polyurethane in building insulation, pavement materials, wood-based panels and other new applications. development efforts to meet the needs of consumption upgrades.

In terms of new chemical materials, carry out research on high-end polyolefins, high-performance engineering plastics, high-performance film materials, degradable plastics, electronic chemicals and other products, and provide key materials for strategic emerging industries such as new energy, new infrastructure, and high-end equipment manufacturing. support. During the “14th Five-Year Plan” period, focus on promoting the research and development of POE complete sets of engineering technology, the industrialization process of nylon 12, the development of high-refractive, bio-based and other special PC manufacturing technologies, the research on the trinity of key raw materials, technology and performance of degradable plastics, and high-end separation membrane materials Key technology research, the implementation of large-scale industrialization.

In terms of fine chemicals, develop water-based surface materials, promote the water-based process of polymer surface materials in my country in various fields such as building materials, industrial coatings, adhesives, and nursing, and promote the transformation and upgrading of traditional industries; carry out research on the utilization of biomass resources, From corn starch, biological waste and natural oils as starting materials, various bio-based chemicals are prepared through chemical transformation and biological fermentation technology.

In 2021, Wanhua Chemical will invest 3.168 billion yuan in research and development, mainly focusing on high-end chemical new materials and solutions, emerging materials and other new business sectors technology incubation investment, such as carbon neutralization related technologies, polyurethane foam degradation and recycling, new energy energy storage And battery materials, separation and purification and other research and development projects. In the field of polyurethane, the sixth-generation MDI technology was successfully applied in Yantai MDI plant, achieving a stable operation of 1.1 million tons per year.

In the future, Wanhua Chemical will continue to increase investment in olefins and downstream industrial chains by taking advantage of the integrated industrial chain of existing industrial parks, vigorously develop Wanhua’s high-performance polyolefin material platform, and promote the transformation and upgrading of China’s polyolefin industrial chain. Relying on the olefin industry chain platform, we will further strengthen and expand the modified plastics business, expand the high-end application downstream of the material business, and continue to develop and advance in the field of new materials.
