Abstract:
1. A process for cooling an acid that is withdrawn from an absorption apparatus of a sulfuric acid plant, the method comprising: pumping the acid to be cooled from an acid pump tank and supplying the acid to a shell space of a heat exchanger; supplying water as a heat transport medium to heat transfer elements disposed in the shell space so as to at least partially convert, by heat transfer from the acid, the water to steam; supplying the acid which was cooled in the heat exchanger back to the absorption apparatus; separating the water from the steam in a steam drum; recirculating the separated water to the heat exchanger using a pump; and simultaneously monitoring process water supply, loading of the plant and concentration of the acid so as to detect a leakage.
