625 million yuan low-carbon project for inorganic acid compounds in Putian, Fujian

Thread Content

Project Name: Low-Carbon Project for Inorganic Acid Compounds
Launch Date: November 06, 2025
Region: Fujian
Industry/Project Type: Chemicals and Pharmaceuticals/Chemical Raw Materials and Chemical Products/Chemical Raw Materials
Project Owner: Wanrong Industrial Co., Ltd., Xiuyu District, Putian City
Total Investment: 625 million yuan
Current Progress: Project registration completed
Construction Location: Shimen’ao Industrial Park, Dongzhuang Town, Xiuyu District, Putian City, Fujian Province
Construction Content: Utilize the high-temperature heat energy from inorganic acid production processes as well as the medium-temperature heat energy generated from SO2 conversion to achieve recycling of medium-pressure superheated steam. By achieving energy savings and reduced consumption, energy losses that occur during the conversion of thermal energy into electrical energy and then into mechanical energy are avoided. At the same time, advanced domestic low-temperature heat recovery systems are fully utilized; the low-pressure steam generated can be entirely recycled into the low-pressure steam network, where it is preheated using some of the heat produced by the conversion of SO2. This results in a steam recycling system for the entire inorganic acid production process, thereby achieving a low-carbon cycle. Area of the main building: 2,500 square meters; additional production capacity (or functional use): establishment of a steam recycling system.
