Abstract

Corrosion in aqueous alkanolamines, physical solvents, or combination of alkanolamines and physical solvent solutions used to remove acid gases from natural gas, synthetic gas, or light hydrocarbon streams can be reduced by addition of mixtures of oxygen scavengers or mixtures of oxygen scavengers and sodium molybdate. The oxygen scavengers must be promoted to reduce metal surfaces in contact with the solutions to a more passive, harder and insoluble form at the operating temperature of the treating system. The sodium molybdate provides additional passivation especially in the imperfections on the surface of the metal where corrosion accelerates

Claims (4)

1. ~A method of reducing suspended or soluble iron or other metals in gas or light hydrocarbon treating solutions utilizing alkanolamine aqueous solutions or physical solvents or combinations thereof by adding to the treating solution in a concentration of from 0.001 to 50,000 ppm sodium molybdate.
2. ~The method of claim 1 wherein sodium molybdate is added in a concentration of from 1 to 5,000 ppm to the treating solution.
3. ~The method of claim 1 wherein sodium molybdate is added in a concentration of from 1 to 500 ppm to the treating solution.
4. ~The method of claim 1 wherein sodium molybdate is added in a concentration of from 1 to 50 ppm to the treating solution.
