#Innovative Solution for Regenerating Spent Hydrochloric Pickling Acid in Stainless Steel Processing

The regeneration of hydrochloric acid in stainless steel pickling poses a major challenge due to the high concentration of ferric chloride (FeCl3), complicating conventional recovery methods. SUSTEC’s REGMAX-CL technology offers an efficient solution, fully recovering hydrochloric acid while reducing environmental impact.

Technology Background

*Hydrochloric acid and hydrogen peroxide in stainless steel pickling: Mechanisms

Stainless steel requires surface treatment to remove impurities formed during the manufacturing process. Pickling is a critical step that removes oxide scales, residues and contaminants, thereby restoring the corrosion-resistant properties of the material. Some stainless-steel manufacturers use hydrochloric acid (HCl) as a pre-pickling agent due to its effectiveness in dissolving oxide scale. When combined with hydrogen peroxide (H₂O₂), pickling efficiency and surface quality are further enhanced. This article examines the mechanisms and benefits of using HCl and H₂O₂ in stainless steel pickling.

REGMAX: Improving the Energy Efficiency of Stainless Steel Pickling

01-2020 mission-innovation.net - Mission Innovation Breakthroughs - The REGMAX® technology has the potential to eliminate waste acids from the global stainless steel industry and to recover more than 350,000 liters of waste acid every hour, which will equate to more than 400 MW in energy savings. Its implementation could be accelerated by placing pressure on the stainless steel industry to use the technology or providing funding for smaller plants to make the return on investments more attractive.
