Abstract
Highly exothermic reactions in a Sulphuric Acid Plant are sources of energy that can be used effectively in metallurgical facilities. Unfortunately, this aspect does not receive the attention that it deserves while designing smelting and/or hydrometallurgical plants. High temperatures in gas circuits allow heat recovery as steam which is a very valuable source of energy. Over the last two decades, development of higher quality materials of construction has allowed the operation of acid circuits at high temperatures, resulting in increased opportunity for heat recovery as steam. This paper discusses various options for recovering heat and utilizing it effectively in metallurgical facilities.
