"Chromium salt is one of the eight basic chemical raw materials, which is indispensable to the national economy. In the national economy, it is related to 10% of industrial products." In 2009, the board of directors decided to use the self-developed pneumatic fluidized tower technology to produce Sodium chromate, committed to the development of advanced production methods, successfully developed pneumatic fluidized tower - continuous electrolysis - wet iron oxide powder clean and environment-friendly process. ※ 2009 Board of Directors Resolution on Pneumatic Fluidization Tower Development Strategy ※ March 11, 2011 "Pneumatic fluidization tower continuous liquid phase oxidation production of chromate (sodium, potassium)" identified by China Petroleum and Chemical Industry Association expert group as "production technology and equipments achieves international advanced level" ※ 2011 National Development and Reform Commission No.9 Order "Catalog of Industrial Structure Adjustment Guidance Catalog (2011)" ※ 2011 Ministry of Industry and Information Technology Energy Conservation Division (2011) circular 381 "chromium salt industry cleaner production implementation plan" for promotion of clean production technology, our technology is recommended to accelerate the industrialization of demonstration applications. ※ November 13, 2013 Gansu Industry and Information Technology Commission experts group identified “continuous liquid phase oxidation system for producing sodium dichromate technology by Pneumatic fluidized tower” for the international leading level ※ April 26, 2014 Gansu Industry and Information Technology Commission experts group identified “ion-exchange membrane continuous electrolytic sodium dichromate technology” for the leading domestic level ※ November 11, 2014 Gansu Industry and Information Technology Commission experts group identified “wet iron oxide powder technology” as international advanced level and “iron oxide red technology” as domestic leading level, successfully solved the global problem of chromium residue, the chromium residue from hazardous waste Into a general industrial solid waste ※ April 20, 2016 Gansu Baiyin 100,000 tons / year sodium dichromate and supporting clean production project commemorative ceremonyPatent show
