This paper discusses the experience with selected practices in the life cycle of a gas plant and their impact on equipment damage mechanisms, corrosion rates and eventual life expectancy of the plant. A number of selected practices at the design, construction, operation and maintenance phases are evaluated. Alternative options to each practice are discussed and the potential effect of selected practice on type and severity of damage mechanisms experienced are outlined. Design practices discussed include material selection, solvent selection and equipment sizing. The construction practices include welding, heat treatment, and project quality control. And the operation practices include raw gas composition, solvent circulation and testing, and corrosion monitoring. Maintenance cycles as well as maintenance practices are also examined.
