FIELD: petroleum products storage. SUBSTANCE: method consists in that light fractions are trapped by way of mixing oil tank gas with a portion of crude oil (from 1 to 15 t per hour), cooling the mixture, separating the phases, and directing saturated crude oil phase by gravity back into the tank or into crude oil stream from the tank. Mixing of tank gas with crude oil is carried out in countercurrent in a pipeline, crude oil being preliminarily cooled and then sprayed in gas stream. EFFECT: reduced loss of light hydrocarbons. |
