![]() ![]() Other areas that are affected include heat exchanger tubes near the inlet nozzle, the amine contactor near the sour gas inlet, and the amine regenerator near the rich amine inlet. Areas that are subject to erosion-corrosion include the piping from the amine contactor pressure let-down valve to the rich amine flash drum, the piping from the rich amine flash drum level control valve to the amine regenerator, and the lean amine pump (see Figure 3-1). Erosion-corrosion removes the protective iron sulfide, carbonate, or oxide film protecting the piping and equipment from corrosion. Nielsen, in Gas Purification (Fifth Edition), 1997 Erosion-CorrosionĮrosion-corrosion is caused by high amine solution velocities, solution turbulence, and impingement of gas and amine on metal surfaces.
