Title: CORROSION INHIBITOR COMPOSITIONS AND METHODS OF USING SAME
Abstract:
We disclose the use of an aliphatic tertiary amino functional compound to suppress H2S formation of a sulfur-based corrosion inhibitor during storage of the sulfur-based corrosion inhibitor in a substantially enclosed container. Thus, disclosed herein is a stabilized corrosion inhibitor composition comprising a sulfur-based corrosion inhibitor and an aliphatic tertiary amino functional compound. Also disclosed herein is a method of storing a corrosion inhibitor composition by combining a sulfur-based corrosion inhibitor and an aliphatic tertiary amino functional compound to form a stabilized corrosion inhibitor composition; and storing the stabilized corrosion inhibitor composition in a substantially enclosed container for a storage period, wherein substantially no H2S is formed within the container during the storage period.
