FIELD: neutralizers.
SUBSTANCE: invention relates to the neutralization of hydrogen sulphide and various mercaptans present in hydrocarbon media. The invention relates to a hydrogen sulphide neutralizer, including polyamine, synthesized on the basis of urea-formaldehyde concentrate and ammonia water 10-55 wt.%, aliphatic alcohol 3-30 wt.%, nonionic surfactant in the form of neonol AF 9-12 in the amount of 1-4 wt.%, organic base – a mixture of spent N-methyldiethanolamine and monoethanolamine 3-15 wt.%, sodium or potassium hydroxide 0.05-0.5 wt.%, the rest is urea-formaldehyde concentrate KFK-85.
EFFECT: optimization of the composition of the neutralizer of hydrogen sulphide and mercaptans in produced oils while maintaining the high efficiency of their purification at the required level.
