Metso delivers scrubbers to India for SO₂ emissions reduction

Metso will deliver four Peracidox™ scrubbers to Hindustan Zinc to minimize sulfur dioxide emissions at their plants. The scrubbers will be installed at the sulfuric acid plants at the company’s zinc smelters in Chanderiya and Debari in India.

Metso has delivered numerous Peracidox™ scrubbers around the world. The ones to be delivered to Hindustan Zinc have been customized for the Indian market to comply with the stringent local environmental regulations and to meet the needs of the Indian customers,” says Hannes Storch, Vice President, Metals and Chemical Processing at Metso. Metso’s Peracidox™ scrubber efficiently reduces the residual SO₂ of tail gases, minimizing emissions. The solution, an oxidative removal process, features high removal efficiency and ease of control with minimized mechanical equipment. It can be installed as part of a new plant or in existing ones. The Peracidox™ scrubber can be used, for example, to reduce SO₂ emissions downstream in existing sulfuric acid plants.
