​Add 600,000 tons of MDI production capacity! Wanhua Chemical’s global MDI production capacity will account for 32%!

Recently, according to Wanhua’s official website, Wanhua Chemical (Ningbo) Co., Ltd. (hereinafter referred to as “Wanhua Chemical Ningbo” or “Enterprise”) MDI/HDI technical renovation and expansion integrated project and 1.8 million tons/year MDI technical renovation project Disclosure of environmental impact assessment information.

Wanhua Chemical Ningbo’s 1.8 million tons/year MDI technological transformation project has an investment of 941 million yuan, mainly for the expansion and transformation of the existing MDI device, and finally the production capacity of the first phase of the MDI device will be expanded from the existing 400,000 tons/year to 600,000 tons/year, the second-phase MDI plant capacity will be expanded from the existing 800,000 tons/year to 1.2 million tons/year. In total, the entire plant has 1.8 million tons/year of MDI production capacity, which is the previous market’s expansion of Ningbo’s production capacity of 300,000 tons per year. T twice as expected.

This expansion project is mainly based on the previous expansion technology of Yantai, with very low investment in fixed assets, and the single set production capacity continued to break the record of 1.1 million tons per year for Yantai Wanhua, reaching 1.2 million tons per year. Considering the investment in other projects such as supporting projects, the investment per ton of Wanhua Chemical Ningbo's expansion is only 69 million CNY/ton, which is slightly lower than the cost of Yantai's expansion. After the 600,000-ton/year technological transformation project of Wanhua Chemical's Ningbo MDI plant is put into operation, the global production capacity will reach 3.2 million tons, with a market share of 32%, further consolidating its leading position in the polyurethane industry.

In addition, Wanhua Chemical Ningbo MDI/HDI technical transformation and expansion integration project has a total investment of 3.221 billion yuan. The construction content includes a new 280,000 tons/year modified MDI device, 50,000 tons/year HDI monomer device, and 60,000 tons. /Year HDI adduct device, 12+240,000 tons/year hydrogen chloride device, 240,000 tons/year formaldehyde device, supporting transformation of gas generating device and related auxiliary supporting projects. After the project is fully put into operation, the entire Ningbo plant of Wanhua Chemical will have a production capacity of 300,000 tons/year of modified MDI, 100,000 tons/year of HDI monomer, and 580,000 tons/year of hydrogen chloride. The cold box capacity will also be 12,000Nm3. /h is increased to 18000Nm3/h, and the production of modified MDI and HDI will also increase the added value of Wanhua products.

As of the end of 2020, the global MDI production capacity is 8.99 million tons, and Wanhua Chemical’s global production capacity is 2.1 million tons/year (including domestic annual production capacity of 1.8 million tons and Hungary’s annual production capacity of 300,000 tons). Its global production capacity accounts for After this expansion, Wanhua Chemical’s global MDI production capacity reached 2.6 million tons/year, and its global production capacity increased to 27%. In the next few years, Wanhua Chemical’s MDI capacity expansion plan will continue. It has already announced the 400,000 tons/year MDI new construction project in Fujian and the Ningbo MDI technological transformation project (Ningbo’s existing MDI production capacity is 1.2 million tons/year, and plans to expand The production is 1.5 million tons/year). The two projects are expected to achieve production capacity contributions around 2023-2024. By then, Wanhua Chemical’s global MDI production capacity will reach 3.3 million tons/year, accounting for 32% of the global production capacity.

This time through the technological transformation to expand the production capacity by 500,000 tons/year, the cumulative investment is only 284 million yuan, and the corresponding investment per ton is only more than 500 yuan. If calculated by 15 years of depreciation, the annual depreciation cost per ton is less than 40 yuan. Greatly reduce operating costs. According to the project’s environmental assessment data, Ningbo’s MDI expansion is achieved by increasing the production time of the plant from 7200h/a to 8000h/a, increasing the total production capacity of the MDI plant to 1.5 million tons/a. Therefore, the investment cost of the expansion will not be Very high.

Wanhua Chemical (Ningbo) Co., Ltd. plans to implement an integrated MDI/HDI technological transformation and capacity expansion project and a 1.8 million tons/year MDI technological transformation project in the existing plant area at No. 39 Huandao North Road, Daxie Development Zone, Ningbo. The environmental impact assessment of the project was entrusted to Zhejiang Renxin Environmental Science Academy Co., Ltd. to carry out. In accordance with the relevant requirements of the "Measures for Public Participation in Environmental Impact Assessment," Wanhua Chemical (Ningbo) Co., Ltd. discloses the environmental impact assessment related information of the construction project as follows.
