High pressure / high temperature dynamic multiphase corrosion-erosion simulator

A method of performing high pressure, high temperature dynamic multi-phase testing system for testing corrosive and corrosive-erosive environments in a test vessel, comprising the steps of:

• preparing a test system, the test system including:
• a plurality of ring-shaped test coupons;
• a casing defining an inner section;
• a plurality of spacer rings disposed vertically relative to one another and supported by the casing;
• wherein at least a first, second, and third ring-shaped test coupons among the plurality of ring-shaped test coupons are each disposed between at least two of the plurality of spacer rings, wherein the first, second, and third ring-shaped test coupons are disposed at a respective an upper section, middle section, and lower section of the casing;
• and
• a plurality of separator plates, wherein one of the plurality of separator plates is disposed between the upper and middle section of the casing and another of the plurality of the separator plates is disposed between the middle and lower section of the casing;
• a rotor shaft disposed within the housing and arranged to turn within the test fluids;
• first and second impellers supported by the rotor shaft and positioned to stir the test fluids within the housing,
• providing a test fluid mixture that is at a different phase at different locations within the system and which is in surrounding relation to the plurality of ring-shaped test coupons, wherein the separator plates are configured to maintain a separation between each of the phases of the multi-phase test fluids so that each of the ring-shaped test coupons is exposed to a different phase or combination of phases of the test fluids;
• maintaining, for a period of time, a temperature and pressure within the test vessel, wherein the temperature and pressure simulate a severe environment;
• and
• inspecting the plurality of ring-shaped test coupons for corrosive and corrosive-erosive effects.
