FIELD: oil and gas processing.
SUBSTANCE: neutralizer contains 30-60% formalin, 0.1-3% alkali metal (sodium) hydroxide and/or carbonate, 5-35% bactericidal agent, preferably Baktsid, Sontsid, or Sulfan, and tertiary aminoalcohol (triethanolamine and/or methyldiethanolamine) to 100%. Neutralizer may further contain urotropin in amount from 5 to 22%. With such composition, effective neutralizer is characterized by high processability (low freezing temperature) and reactivity, which favors high degree of purification of crude oil, petroleum products, and hydrocarbon gases polluted by hydrogen sulfide and light mercaptans.
EFFECT: enhanced neutralization activity accompanied by bactericidal activity and anticorrosion effect in hydrogen sulfide-containing media.
