GLRPPR Sector Resource: Nitric Acid Pickling Bath Recovery

Title:
Nitric Acid Pickling Bath Recovery

Abstract:
Gerlin Inc., located in Carol Stream, IL manufactures stainless steel pipe fittings and flanges. As part of Gerlin’s process, stainless steel parts undergo a pickling bath step to provide the parts the required surface quality. The bath becomes depleted in 6-8 weeks and is recharged seven times per year. Gerlin’s waste disposal costs run $18,000 per year and fresh chemical make-up costs are $13,000 per year. Besides becoming depleted, the pickling process is also a bottleneck in Gerlin’s operation. WMRC engineers developed a pilot project using diffusion dialysis acid recovery technology to assist Gerlin. (PDF Format; Length: 1 page)
