Abstract:
1. A device for condensing volatile organic compounds (VOC) from a storage or transport tank into oil from the same or another storage or transport tank via a downcomer directing flow, wherein the upper part of the downcomer, which upper part defines a flow path having a cross sectional area perpendicular to the direction of flow that is substantially unreduced, is connected to a gas pipe, the gas pipe communicating with the flow path, and where the upper part of the downcomer is arranged at a sufficient height above the upper part of the storage or transport tank to cause an inflow of gas from the upper part of the storage or transport tank to the flow path due to the underpressure being created in the upper part of the downcomer when oil flows down through the downcomer.
