Thread Content

On December 5, the Taizhou Ecology and Environment Bureau published its approval comments on the environmental impact assessment document for Kent Catalytic Materials Co., Ltd.’s project to upgrade its production capacity to manufacture 2,767 tons of new material catalysts per year. The details of the project are as follows: Project name: Kent Catalytic Materials Co., Ltd.’s project to upgrade production capacity to manufacture 2,767 tons of new material catalysts per year； Construction unit: Kent Catalytic Materials Co., Ltd ； Construction location: No. 7 Fengxi West Road, Modern Industrial Zone, Xianju County, Zhejiang Province ； Project nature: Technical renovation ； Construction content and scale: This project will be carried out within the existing old factory area of the enterprise, specifically in the existing Synthesis Workshop 1, Synthesis Workshop 2, Synthesis Workshop 3, and Electrolysis Workshop. ①In the electrolysis workshop, the 200 t/a tetramethylammonium hydroxide production line, the 250 t/a tri(2-hydroxyethyl)methylammonium hydroxide electrolysis process, and the 100 t/a triphenylethylphosphonium acetate electrolysis process operate in conjunction with the existing production lines for tetraethylammonium hydroxide and hexamethyldiammonium hydroxide ； ②In Synthesis Workshop 1, the production processes for 100 t/a of 2-(N-ethylanilino)ethyl-(2-hydroxypropyl)-dimethylammonium sulfate and tri(2-hydroxyethyl)methylammonium hydroxide will be carried out in conjunction with the existing production of tri*** phosphonium chlorides, while the existing 1000 t/a production line for bromobutane will be phased out ； ③In Workshop 2 for synthesis, the production processes for 50 t/a of tetraethylammonium benzoate, 100 t/a of tetrabutylammonium dibenzoate, 200 t/a of tetrabutylphosphonium acetate, and 100 t/a of triphenylethylphosphonium acetate are integrated with the existing production line for tetraethylammonium bromide ； ④In Workshop 2 for synthesis, the existing production capacity of 234 t/a of tetrabutylammonium fluoride is expanded to 500 t/a, while the capacity of existing tetraethylammonium fluoroborate is reduced from 300 t/a to 50 t/a; these processes are integrated with the existing production of products such as tetrabutylammonium fluoroborate, tetrabutylphosphonium difluoride, and tetrabutylammonium fluoride furan solutions ； ⑤The existing fluorocarbon surfactants are phased out in Synthesis Workshop 2 to produce 1,500 t/a of tetrabutylammonium acetate, which has its own dedicated production line. ⑥A new production line with a capacity of 0.5 t/a for dibutyldicyclohexyl-18-crown-6 and 0.5 t/a for dicyclohexyl-18-crown-6 will be built on the available space in Workshop 3 for synthesis, utilizing a fixed-bed continuous production process. At the same time, the existing production capacity of 18-crown-6 will be reduced from 100 t/a to 98 t/a to ensure that pollutant emissions from the synthesis Workshop 3 do not increase.
