Acid Management for Carbon Steel Pickling Zero Effluent Design

Acid Management for Carbon Steel Pickling Zero Effluent Design
Zero Effluent for Pickling Lines & Acid Regeneration has been developped by TENOVA to reduce costs and environmental impact. Many years of experience and know-how in the field of acid regeneration and pickling lines for steel strip enabled Tenova to develop a complete compact package to provide optimised, tailored and an all-comprehensive solution for pickling lines with dedicated acid regeneration units. The increasing market demand for small size and low cost pickling lines, as well as increasing costs for energy, water and environment requires a new approach and a new concept for this kind of application. In a conventional design, the excess rinse water containing chlorides is sent to a plant for neutralization which are losses and lead to: 1) costs for fresh make up acid 2) water costs (demi water or condensate) for rinsing use 3) costs for neutralisation 2012 SEAISI Seminar
