Pickling passivation is a key process in the stainless steel production process, but every ton of stainless steel produced approximately 60 kg of waste sulfuric acid with a concentration of 20%, which poses a risk of environmental pollution

Pickling passivation is an important means to make the surface of stainless steel smooth and clean.

In response to the above-mentioned industry needs, Qi Tao’s team, a researcher from the Resource and Environmental Green Process Engineering Research Department of the Institute of Process Engineering, has developed a new acid complex precipitation technology and established a complete new process for the cleaning and treatment of waste sulfuric acid in the stainless steel pre-washing section.

After the promotion and application of new technologies for the clean recovery and recycling of waste acid from stainless steel washing, it will increase the economic, environmental and social benefits of stainless steel production enterprises, promote the upgrading of the stainless steel industry, and help the sustainable development of China's industrial greening
