Green Corrosion Inhibitor Achievements - Assessment of Performance vs. Reality of Regulation

摘要

Development of more environmentally acceptable corrosion inhibitors is a challenge. As a result of their chemistry, the products used for oilwell stimulation have active ingredients that may be harmful if discharged to the marine environment. This paper will focus on the technical achievements of recent corrosion inhibitor developments vs. the traditional inhibition with amines and acetylenic alcohols for inhibition of acid stimulation fluids. The decisions mandated by OSPAR are reviewed and the recent changes in regulations are highlighted. Alternative amine inhibitor intermediates that have been used will also be discussed in view of performance vs. OSPAR regulations.
