Hydrocarbon Processing: Non-phosphorus corrosion inhibitor optimizes cooling tower uptime for environmental compliance

Cooling water systems play a critical role in the efficient operation of hydrocarbon processing facilities. Ensuring that these systems efficiently cool and condense the various process streams is essential to minimizing operating costs and maximizing plant performance and profitability. Common challenges to maintaining these systems at peak performance come in the form of corrosion, pitting and buildup of mineral scale on heat exchanger surfaces.1,2 If left unchecked or poorly controlled, corrosion and pitting shorten the lifetime of the system equipment, while scaling decreases the efficiency of heat flow across the metal surfaces. Corrosion inhibitors are a commonly deployed solution to mitigate corrosive attack. These chemicals contain targeted functional moieties that assemble on the metal surface of a heat exchanger and other cooling tower structures. Once at the surface, the inhibitors may disrupt the electrochemical reactions occurring at the cathode or anode, or form a passivation layer that…
