Tianjin Huanbo New Materials Co., Ltd. High Purity Chemicals (Electronic Grade Chemicals) Production Phase II Project

Second Announcement of Environmental Impact Assessment

Release date: May 25, 2023

1、 Name and Overview of Construction Project

Project Name: Tianjin Huanbo New Materials Co., Ltd. High Purity Chemicals (Electronic Grade Chemicals) Production Phase II Project

Construction unit: Tianjin Huanbo New Materials Co., Ltd

Construction nature: renovation

Construction location: Within the existing factory area of Tianjin Huanbo New Materials Co., Ltd., No. 67 Gangshi Street, Dagang Petrochemical Industrial Park, Tianjin

Construction Content: Tianjin Huanbo New Materials Co., Ltd. plans to invest 100 million yuan in the construction of the "Tianjin Huanbo New Materials Co., Ltd. High Purity Chemical (Electronic Grade Chemical) Production Phase II Project". The main construction content is to rely on the existing sulfuric acid production unit area, SO3 greenhouse, and electronic grade sulfuric acid workshop, add an electronic grade sulfuric acid production line, and support the construction of factory pipelines and finished product storage tanks, By utilizing the primary conversion flue gas produced by the existing annual production line of 200000 tons of sulfur based sulfuric acid, the existing product structure can be adjusted by adjusting some of the flue gas used in the existing industrial acid production line to the electronic grade sulfuric acid production line of this project. After the completion of this project, the existing industrial sulfuric acid (98% industrial grade) production has decreased by 29400 tons/a, and a new high-purity sulfuric acid (electronic grade sulfuric acid) has been added by 30000 tons/year. Among them, the annual production of E3 grade and above electronic grade sulfuric acid is 27500 tons/year, 96.5% E4 grade electronic grade sulfuric acid is 10000 tons/year, and 96.5% E5 grade electronic grade sulfuric acid is 1500 tons/year, totaling 30000 tons/year of electronic grade sulfuric acid..
