High pressure / high temperature dynamic multiphase corrosion-erosion simulator

Abstract

A system for measuring corrosion and corrosion-erosion rates in a high temperature, high pressure multiphase dynamic environment includes a plurality of ring-shaped test coupons disposed within a test vessel in a vertical arrangement relative to one another. A test fluid mixture is added to the vessel and the temperature and pressure are maintained such that the mixture exists in a multiphase condition that has a vertical stratification such that each test coupon is exposed to a different phase and/or combination of phases of the fluid. Impellers can be used to stir the fluid to provide a dynamic environment. The fluid can include particulate matter to simulate real world test conditions. Separator plates can be disposed at different vertical locations within the vessel to maintain separation between various phases of the fluids and further restrict particulate matter from migrating between sections of the test system.
