JSW commissions second acid regeneration plant at Vasind Works

India's JSW Steel Coated Products has commissioned a second acid regeneration plant supplied by Andritz at its Vasind Works in Maharashtra.

The new plant has a processing capacity of 6,400 liters of spent pickling acid per hour and was installed to support a new pickling line with an annual processing capacity of 1.3 mln tons.

The acid regeneration technology enables the recovery and reuse of spent hydrochloric acid while producing iron oxide as a by-product for industrial applications. Regenerated acid now covers around 99pct of the pickling operations' acid requirements, reducing waste generation and the need for fresh acid.

The new facility has achieved stable operations following start-up and performance validation. The two Andritz acid regeneration plants now support the pickling operations at Vasind Works.

JSW Steel Coated Products, a wholly owned subsidiary of JSW Steel, has downstream manufacturing capacity of around 5.2 mln tons per year. The company produces cold-rolled, galvanized, galvalume, color-coated and tinplate products at facilities in Vasind, Tarapur, Kalmeshwar and Khopoli in Maharashtra, Bawal in Haryana, Rajpura in Punjab, Dhar in Madhya Pradesh and Pulwama in Jammu and Kashmir.
