FIELD: oil production and oil processing industries.
SUBSTANCE: neutralizing composition contains 16 to 35% of alkali metal nitrite (preferably sodium nitrite), 3 to 30% of nitrogen-containing basic and/or alkaline reagent (monoethanolamine, tricthanolamine, methyldiethylethanolamine, and/or ammonia), and water to 100%).
EFFECT: increased neutralization efficiency in crude oil and petroleum products, lowered acidity and corrosive activity of treated medium, and increased assortment of accessible, inexpensive, and process-adaptive neutralizers.
