摘要
A method and apparatus for the recovery of heat from a sulfuric acid process are provided. Sulfur trioxide is absorbed into hot concentrated sulfuric acid, acid having a concentration greater than 98% and less than 101% and a temperature greater than 120° C., in a heat recovery tower and the heat created by the exothermic reaction is recovered in a useful form in a heat exchanger.
