Abstract: A method of inhibiting corrosion of a metal surface in contact with an aqueous medium is provided. The method may include contacting the metal surface with a corrosion inhibitor composition where the corrosion inhibitor composition may include a phosphino succinic oligomer (PSO); an azole; and a molybdate. The disclosed corrosion inhibitor composition is especially useful for inhibiting corrosion in mixed metallurgy systems.

Abstract: The disclosed systems and method for evaluating the integrity of media pads within an adiabatic cooling system includes at least one media compartment containing at least one media coupon that is representative of at least one of the media pads. The system is adapted to be fluidly coupled to a source of representative process water and to provide such water to the at least one media compartment. A source of airflow fluidly is also coupled to the at least one media compartment. The flow of representative process water and airflow to the media coupon within the media compartment simulates the operation of the adiabatic cooling system. The at least one media coupon may then be analyzed as representative of media pads within the adiabatic cooling system.
