MDEA (methyldiethanolamine) is a concentrated amine that is used as a pH buffer/corrosion inhibitor. MDEA is soluble in water and alcohols (glycols). MDEA is used in process water and glycol systems to maintain a neutral-to-slightly alkaline solution to keep the corrosivity in the system at a minimum. It is also excellent for mixing into diethylene glycol (DEG) in connection with hydrate inhibition. MDEA is applied until the required pH is achieved. Nitrite-base products should not be used in connection with this product since potentially hazardous nitrosamines can be formed.
