FIELD: chemistry.
SUBSTANCE: invention concerns preparation of market-grade oil, particularly method of hydrosulfide and light mercaptans neutralisation in market-grade oil by feeding hemiformal solution via perforated disperser in the form of perforated tube with orifices installed in technological pipeline site after demineralisation process and before end separation aggregate. Also invention concerns hemiformal and hydrocarbon nitrocompound mix composition for hydrosulfide and methyl-ethyl mercaptans neutralisation in market-grade oil.
EFFECT: possible neutralisation of hydrosulfide and mercaptans in market-grade oil without ballast formation and preparation process disruption.
