Patent number: 6279514Abstract: The invention provides a heat recovery method for use in sulfuric acid production plants by which the heat generated in the step of drying SO2 gas or the step of drying air, and the step of absorbing sulfur trioxide in the plant is effectively utilized for heating the water to be supplied to a boiler although the heat is conventionally discarded because of the difficulties encountered in using the heat effectively. The boiler water to be supplied is heated by utilizing the heat generated by drying and/or absorption in a drying tower of the plant for drying sulfur burning air or the sulfur dioxide and/or in an absorption tower of the plant for causing circulating concentrated sulfuric acid to absorb sulfur trioxide produced by the conversion of the sulfur dioxide.Type: GrantFiled: August 7, 2000Date of Patent: August 28, 2001Assignees: Hitachi Zosen CorporationInventors: Timothy J.
