FIELD: crude oil treatment.
SUBSTANCE: invention relates to process wherein high-sulfur oils and gas condensate with high levels of hydrogen sulfide and mercaptans are prepared for transportation. Process consists in multistep separation including vacuum separation of hydrogen sulfide. Separation is carried out at pressure allowing separation no more than 90% of total hydrogen sulfide, after which oil is supplemented by effective amount of neutralization reagent and resulting mixture is then kept at 15 to 65°C over a period of time long enough to neutralize hydrogen sulfide still contained in oil to desired level.
EFFECT: lowered residual content of hydrogen sulfide and mercaptans in commercial crude oil to existing requirements without treatment loss.
