ABSTRACT:
Leakage is detected between a process fluid and a temper fluid, or from a process fluid to a temperature-conditioning fluid, wherein one but not both of said A and said B fluids is an industrial process fluid and wherein at least one of said A and said B fluids is a gaseous stream, in an industrial process. The industrial process includes an A and a B fluid, and one of the A and B fluids receives heat from or transfer heat to the other of the A and the B fluids by an indirect contact method, and one but not both of the A and the B fluids is an industrial process fluid. In particular, the A fluid is a temperature-conditioning fluid that receives heat from a process fluid, for instance wherein the A fluid is the water of a waste-heat boiler and the B fluid is a gaseous process stream.
