What you will learn
• Understand the fundamental desalination processes—seawater reverse osmosis (SWRO), multiple effect distillation (MED), and multi-stage flash (MSF)—and the corrosive environments associated with each system.
• Explain the corrosion mechanisms affecting materials in desalination service, including pitting, crevice corrosion, stress corrosion cracking, galvanic corrosion, and erosion–corrosion in seawater and brine environments.
• Differentiate the performance and application limits of carbon steels, stainless steels, duplex and super duplex stainless steels, nickel-containing alloys, copper alloys, and titanium in desalination plant components.
• Evaluate how operating conditions such as temperature, pressure, chloride concentration, redox potential, flow velocity, and oxygen content influence material selection and corrosion resistance.
• Identify appropriate materials and fabrication practices for key desalination plant equipment, including pumps, piping, valves, filters, heat exchangers, membrane pressure vessels, and energy-recovery systems.
• Interpret service experience, corrosion data, and comparative alloy guidance to make informed, reliable, and cost-effective materials-selection decisions for desalination facilities.
