New Class of "Green" Corrosion Inhibitors: Development and Application

Use of chemical corrosion inhibitors is common in production and processing operations. Particularly challenging is the development of new chemistries, which maintain good protection of materials under a variety of conditions while being environmentally acceptable. This paper illustrates patented work in the chemistry of Alkylpolyglucosides (APGs) and their synergistic effect with polyaspartates. This inhibitor class demonstrated good general inhibitor performance in several oilfield brines, showed good filming characteristics under conditions of shear, and provided an excellent environmental profile.
