India’s phosphate production is using increasing volumes of sulphuric acid, but new domestic smelter and sulphur burning acid capacity may mean reduced imports in future.

A sulphuric acid plant in Northwest China is looking to capture its low-grade heat for re-use. With the support of Alfa Laval’s semi-welded plate heat exchangers and energy recovery expertise, in winter, all of the recovered low-grade heat could be put back into their system with 30% being used in production and the remaining 70% going to heating. During the summer, 14% of the energy that is no longer needed for indoor heating could be used to preheat boiler feedwater. This would enable them to significantly reduce the amount of fossil fuels used in production, without redesigning their entire factory footprint.

Condensate formation in sulphuric acid plants can cause severe corrosion problems leading to high maintenance and plant downtime. Santhosh S . of Metso Outotec discusses the importance of carrying out regular monitoring and maintaining accurate and detailed data about condensate to increase equipment life and avoid downtime. Different sources of condensate formation in the plant are discussed as well as the typical locations in the plant where the condensates end up.
