Electrical Resistance corrosion probes have been used successfully as chemical process indicators and controls in production plants where conductivity, moisture, and pH controls have previously proven ineffective. Examples showing the effectiveness of corrosion sensors in these uses include (1) the control of an acid-saturated organic neutralization where pH control was ineffective because the organic constituent fouled the pH electrode, (2) a brine recovery column where pH control was inadequate to maintain the brine sufficiently neutral for the removal of organics by stripping in a carbon steel column, (3) an anhydrous acid gas facility where corrosion probes were used to assure the dryness of the gas before it entered a steel distribution system, and (4) an anhydrous halogenated organic production plant where corrosion probes were installed for water detection as well as equipment protection.
