Summary of the lecture
This course is based on Materials Selection for Desalination Plants: A Guide to the Use of Nickel-Containing Alloys (No. 11029), published by the Nickel Institute.
It provides practical guidance for engineers, materials specialists, and plant personnel involved in the design, construction, operation, and maintenance of desalination facilities. The publication explains how different alloys—particularly stainless steels, duplex and super duplex grades, nickel-containing alloys, copper alloys, and titanium—perform in the aggressive environments found in seawater reverse osmosis (SWRO), multiple effect distillation (MED), and multi-stage flash (MSF) plants.
The guide focuses on corrosion mechanisms, fabrication considerations, and real-world service experience, with the goal of supporting informed material selection that improves reliability, minimizes corrosion-related failures, and optimizes lifecycle cost in desalination systems.
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.
