摘要：
The invention relates to a system and a method for control of emission of volatile gases (VOC) from a holding tank (80) for crude oil during unloading, loading and transport/holding of the oil, such as in an oil tank on board an oil tanker, in which a blanket gas is used to regulate pressure and amount of combustible gas and to prevent ingress of oxygen into the mentioned holding tank for crude oil. The system comprises a recovery device (50) for recovery of hydrocarbon gas from the holding tank (80) for crude oil, a storage tank (18) for liquid hydrocarbons under pressure, supplied from the recovery device (50), and that liquid hydrocarbons are fed to an evaporation device (70) set up to convert liquid hydrocarbons to gas form, for use as blanket gas in a holding tank (80) for crude oil.
