FIELD: chemistry. ^ SUBSTANCE: hydrogen sulphide neutraliser contains carbamide-formaldehyde concentrate (CFC) 45-99 wt % and organic amine 1-55 wt %. Another version of the neutraliser is described, additionally containing an organic solvent, mainly aliphatic alcohols C1-C5 and/or ethyl-, butyl butyl cellosolves, inorganic base (preferably sodium or potassium hydroxide), and a bactericide preparation (preferably Bakcid or Soncid). ^ EFFECT: increased effectiveness of neutraliser, with high manufacturability and reaction capacity, and which provides for high degree of purification of hydrocarbon and aqueous media from hydrogen sulphide. ^ 8 cl, 13 ex, 2 tbl |
