FIELD: oil and gas industry.
SUBSTANCE: method of removing sulphur oxides from ozonized petroleum or gas-condensate feedstock is carried out by rectification under vacuum with residual pressure of 58.0-95.5 kPa, in the presence of a stripping agent supplied to a column in the amount of 0.8 -2.5% moll. per feedstock, wherein exhaust of vacuum-creating booster steam jet pump is condensed, cooled and the resulting water steam condensate is used for absorption of sulphur oxides.
EFFECT: increased efficiency of sulphur oxide separation from ozonized hydrocarbon mixture by rectification method under vacuum.
