ABSTRACT:
A method of separating volatile organic components, so-called VOC, from crude oil, where, as it is loaded onto a ship, the crude oil is passed into a process vessel (2) in which is established a negative pressure adjusted according to the vapour pressure of the oil, from where the liquid phase of the crude oil flows to the ship's cargo tanks, while the gas phase, the VOC, is extracted from the process vessel (2).
