The first in Guizhou! The 100,000-ton-per-year potassium hydroxide production facility of Guizhou Juliseng Chemical Co., Ltd.’s Kaiyang project was put into operation on April 3, 2025. The commissioning ceremony for this facility was held in Shuangliu Town, Kaiyang County, marking the official completion and operation of Guizhou’s first potassium hydroxide production line. The total investment in Guizhou Juliseng Phosphorus Chemicals series of projects is 5.92 billion yuan; it is funded and constructed by a wholly-owned subsidiary established by Sichuan Juliseng Chemical Co., Ltd. in Kaiyang, with construction taking place in three phases. Once the project is fully completed and put into operation, it is expected to generate an annual output value of 26 billion yuan. It is understood that the first phase of the Juliseng project, which aims to produce 100,000 tons of potassium hydroxide per year, requires an investment of 850 million yuan. This project involves the construction of a production line capable of manufacturing 100,000 tons of potassium hydroxide per year, along with necessary supporting facilities. The core production line utilizes advanced international technology in the form of bipolar zero-gap membrane electrolyzers. The products produced fall into high-value categories such as industrial-grade, food-grade, and electronic-grade ones, and they are widely used in agriculture, the chemical industry, and new energy materials sectors. It is estimated that once operational, this project will generate an additional output value of 620 million yuan. This project not only fills the gap in potassium fertilizer production in Guizhou Province, but it will also facilitate the high-end transformation of the traditional phosphate fertilizer industry in Kaiyang County. It will support the development of industries such as new energy battery materials and special fertilizers, providing strong backing for the comprehensive advancement of economic development, county strengthening, and people’s prosperity.
