Abstract
A device for reducing evaporation of volatile organic compounds (VOC) during filling of a substantially liquid petroleum product into a storage and/or transportation tank (18) via a down pipe (14), wherein the down pipe (14), which has a non-constricted flow-section, is provided with an inlet (22) for gas at its upper portion, the inlet (22) being arranged to enable inflow of gas due to the underpressure being formed in the upper portion of the down pipe (14) when the petroleum product flows down through the down pipe (14).
Claims3
A device for reducing evaporation of volatile organic compounds, so-called VOC, during filling of a substantially liquid petroleum product into a storage and/or transportation tank (18) via a down pipe (14), and where the down pipe (14) is provided with an inlet (22) for gas at its upper portion, characterised in that the down pipe (14) from a loading point (8) has a non-constricted flow-section through its upper portion.
