Thread Content

Project Name: Tangshan Sanyou Electronic Chemicals Co., Ltd.’s project to produce 3,000 tons of electronic-grade hydrochloric acid, 6,000 tons of electronic-grade nitric acid, 12,000 tons of electronic-grade resist diluents, 8,500 tons of electronic-grade propylene glycol methyl ether, and 3,700 tons of electronic-grade propylene glycol methyl ether acetate per year. Launch Date: March 4, 2026. Location: Hebei Province. Industry/Project Type: Chemicals and Pharmaceuticals/Chemical Raw Materials and Chemical Products/Chemical Raw Materials. Project Owner: Tangshan Sanyou Electronic Chemicals Co., Ltd. Total Investment: 690.12 million yuan. Current Progress: Tendering for engineering design. Construction Location: Tangshan City, Hebei Province. Scope of Construction: This project involves the construction of Workshop 4 for wet electronic chemicals, Workshop 5 for wet electronic chemicals, a loading station for resist diluents, loading stations for nitric acid and hydrochloric acid, storage areas for propylene glycol methyl ether and propylene glycol methyl ether acetate, storage areas for nitric acid and hydrochloric acid, and Warehouse 1 of Class D. Expansion of ultrapure water system (including power distribution room), raw material unloading area, and by-product loading area. Expansion of existing public and auxiliary facilities in the power workshop, such as closed-loop water systems, nitrogen, chilled water, and sewage treatment units. The wet electronic chemicals workshop 3 was upgraded and modified, including modifications to the filling process to add a filling system for 200-liter drums of electronic-grade resist diluents, propylene glycol methyl ether, and propylene glycol methyl ether acetate, as well as improvements to the exhaust gas treatment system. The existing wet electronic chemicals filling workshop is being upgraded, with the addition of a filling system for 200-liter barrels of electronic-grade hydrochloric acid and nitric acid. About 230 additional sets of equipment have been added. Progress milestone: February 26, 2026 – Design phase for Tangshan Sanyou Electronic Chemicals Co., Ltd.’s project to produce 3,000 tons of electronic-grade hydrochloric acid, 6,000 tons of electronic-grade nitric acid, 12,000 tons of electronic-grade resist diluents, 8,500 tons of electronic-grade propylene glycol methyl ether, and 3,700 tons of electronic-grade propylene glycol methyl ether acetate per year (engineering design bidding)
