Tangshan Zhonghao Chemical will build new facilities for producing 60,000 tons of polyoxymethylene and 40,000 tons of nylon 66. Author/Source: Coal Chemical Industry Information Network. Date: May 5, 2023. Clicks: 25. On April 27, Kailuan Energy & Chemical Co., Ltd. issued a statement announcing that it would increase its investment in Tangshan Zhonghao Chemical Co., Ltd. to fund the construction of a facility capable of producing 40,000 tons of nylon 66 per year, as well as a facility for producing 60,000 tons of polyoxymethylene along with related supporting facilities. For the 40,000 tons per year nylon 66 project, Tangshan Zhonghao Chemical Co., Ltd. plans to invest 430 million yuan to build a 40,000 tons per year production facility as part of the first phase of a 300,000 tons per year nylon 66 production project within its existing plant site. The company will use its existing adipic acid products, while purchasing hexamethylenediamine as the main raw material to produce nylon 66 products. Under the condition that the raw materials of hexamethylenediamine and adipic acid are available, this project will construct a Phase 1 nylon 66 plant with an annual production capacity of 40,000 tons. The company has built an adipic acid production facility with an annual capacity of 150,000 tons. By utilizing advanced international technologies for the production of nylon 6,6, it is able to further develop the adipic acid-nylon industry chain and move forward toward its higher-value segments. The project utilizes internationally advanced continuous polymerization technology. The maximum production capacity of a single unit is 40,000 tons per year. It features long operation cycles, low energy consumption, stable and reliable product quality, as well as lower operating costs. It represents the most advanced technology available both domestically and internationally, and thus possesses strong market competitiveness. The nylon 66 project is one of the key goals for Kailuan Energy Coal Chemicals in moving forward into the high-value-added field of chemical new materials. 60,000 tons/year polyoxymethylene project: Tangshan Zhonghao Chemical Co., Ltd. currently has a 40,000 tons/year polyoxymethylene production facility. This project mainly involves the construction of a 240,000-ton/year formaldehyde plant and a 60,000-ton/year polyformaldehyde plant. The project covers an area of 66 mu, with a construction period estimated at 29 months. This project has obtained all the preliminary approval procedures required before construction, including **registration, energy efficiency assessment, and environmental impact assessment approvals**. Zhonghao Chemical is a wholly-owned subsidiary of Kailuan Energy & Chemical Co., Ltd., established in 2010. The company is located in the Haigang Development Zone of Tangshan City, Hebei Province. It has currently built a polyoxymethylene production facility with an annual capacity of 40,000 tons, along with supporting facilities including a formaldehyde production plant with an annual capacity of 130,000 tons, an adipic acid production plant with an annual capacity of 150,000 tons and associated nitric acid production facilities as well as a cyclohexanol production plant with an annual capacity of 150,000 tons. There are also 2.5 Ten thousand KW*2 of cogeneration units along with various auxiliary facilities.
