FIELD: chemistry.
SUBSTANCE: invention relates to a hydrogen sulphide and light mercaptan neutraliser which contains, wt %: nitrogen-containing organic base and/or alkali metal hydroxide 0.05-15, paraformaldehyde 1-45 and formalin-methanol mixture - the balance. The invention also relates to a method of purifying oil, gas condensate and fractions thereof from hydrogen sulphide and light mercaptans.
EFFECT: high efficiency of the neutraliser, having high processability and neutralising power, and which provides high degree of purification of hydrocarbon media from hydrogen sulphide with low specific consumption of the neutraliser.
