The invention claimed is: 1. Separation device for separating a liquid/gas mixture in a heavy fraction mainly containing liquid and a light fraction mainly containing gas, comprising: a separation vessel comprising at least one inlet, at least a first outlet for the discharge of the heavy fraction
The invention claimed is: 1. Separation device for separating a liquid/gas mixture in a heavy fraction mainly containing liquid and a light fraction mainly containing gas, comprising: a separation vessel comprising at least one inlet, at least a first outlet for the discharge of the heavy fraction and at least a second outlet for the discharge of the light fraction, an inlet device connected to the inlet for admitting the gas/liquid mixture to the vessel and for distributing the admitted gas/liquid mixture in the vessel, wherein the inlet device is a vane type inlet device, comprising an elongated support structure and a plurality of curved guiding vanes placed one behind the other and attached to the support structure, the guiding vanes being arranged so as intercept and deflect the admitted gas/liquid mixture sideways, a separator for further separating the mixture into the heavy and light fraction; an agglomerator for agglomerating the liquid in the gas/liquid mixture, wherein the agglomerator is arranged in and/or below the inlet device and downstream of the inlet. 2. Separation device according to claim 1, wherein the agglomerator is arranged between the vanes. 3. Separation device according to claim 1, wherein the agglomerator is arranged downstream of the guiding vanes. 4. Separation device according to claim 2, wherein the inlet device is arranged substantially horizontally in an upright separation vessel and the guiding vanes are arranged so as to deflect the incoming mixture substantially horizontally. 5. Separation device according to claim 1, wherein the inlet device is a cyclone type inlet device. 6. Separation device according to claim 1, wherein the separation vessel comprises a bottom part for collecting the heavy fraction and wherein the agglomerator is arranged between the inlet device and the bottom part. 7. Separation device according to claim 6, wherein the agglomerator is arranged over substantially the full cross-section of the separation vessel. 8. Separation device according to claim 6, wherein the agglomerator is arranged over only a part of the cross-section of the separation vessel. 9. Separation device according to claim 6, wherein the agglomerator is arranged along those parts of the vessel wall that are situated sideways of the inlet device. 10. Separation device according to claim 1, wherein the agglomerator is attached to a separate support arranged in the vessel. 11. Separation device according to claim 1, wherein the separator comprise one or more cyclone separators. 12. Separation device according to claim 1, wherein the agglomerator is arranged substantially vertically in the separation vessel, the agglomerator being attached to a support structure. 13. Separation device according to claim 1 wherein the agglomerator extends at an angle between +/-90 degrees relative to the vessel wall. 14. Separation device according to claim 1 wherein the agglomerator is formed by a strip of wire mesh arranged along the inner perimeter of the vessel wall. 15. Inlet device for pre-treatment of a gas/liquid mixture to be separated in a separation vessel, the inlet device being mountable on the separation vessel including at least an inlet for admitting the gas/liquid mixture to a bottom part of the vessel, means for separating the gas/liquid mixture in a heavy fraction mainly containing liquid and a light fraction mainly containing gas, a first outlet for discharging the heavy fraction and a second outlet for discharging the light fraction, the inlet device comprising: an elongated support structure to be connected to the inlet, the support structure being provided with at least a partly open side; a plurality of curved guiding vanes placed one behind the other and arranged at least partly within the support structure, the guiding vanes being arranged so as intercept and deflect the admitted gas/liquid mixture towards the bottom part of the separation vessel; and one or more agglomerators arranged between the guiding vanes for agglomerating the liquid in the gas/liquid mixture. 16. Inlet device according to claim 15, wherein said one or more agglomerators are arranged downstream of the guiding vanes, the agglomerators being attached to the inlet device. 17. Inlet device according to claim 15, wherein said one or more agglomerators are attached to said support structure of the inlet device. 18. Inlet device according to claim 15, wherein the one or more agglomerators are arranged on the face of the outflow area of the guiding vanes. 19. Inlet device according to claim 15, wherein the one or more agglomerators protrude a predetermined distance from the trailing ends of the guiding vanes. 20. Inlet device according to claim 19, wherein the determined distance is between 0 and 500 mm. 21. Inlet device according to claim 15, wherein the leading end of a guiding vane makes a sharp angle with the direction of the flow of the admitted liquid/gas mixture. 22. Inlet device according to claim 15, wherein the guiding vanes are placed at such a distance from each other that a substantially uniform distribution of liquid and gas is obtained. 23. Inlet device according to claim 22, wherein the distance between successive guiding vanes increases in the direction of the liquid/gas flow. 24. Inlet device according to claim 15, wherein the support structure comprises a top plate and a bottom plate between which the guiding vanes are arranged, the guiding vanes being maintained between the borders of the top and bottom plate. 25. Inlet device according to claim 15, wherein the guiding vanes are arranged in pairs opposite each other, so that each pair deflects part of the admitted liquid/gas mixture towards two opposite sides. 26. Inlet device according to claim 15, wherein the one or more agglomerators comprise a wire mesh. 27. Method for admitting gas/liquid mixture to a separation vessel and subsequently distributing the liquid and gas in the vessel, the gas/liquid mixture being passed through a device as claimed in claim 1. 28. Method for treating a gas/liquid mixture in a separation vessel according to claim 1, comprising the steps of: feeding the gas/liquid mixture through a wire mesh into the lower compartment of the vessel; guiding a part of the mixture through one or more cyclone separators in the upper part of the vessel and carrying the separated liquid part back to the lower compartment and carrying the separated gas part to the second outlet; discharging the mixture from the lower compartment from the first outlet; discharging the mixture from the upper compartment from the second outlet. 29.
