Abstract: The invention relates to a method and apparatus for separating two phases from each other. According to the invention, a stream made up of at least two phases is directed to a separation apparatus, which comprises a separation container (25) and cyclones (26) arranged in the flow direction in parallel and in succession, the cyclones having each an elongate separation chamber wherein the phases are separated from each other. According to the invention, the cyclones used are multi-inlet cyclones (26), the total number of which is at least 10. The stream to be treated is directed to each multi-inlet cyclone (26) in a substantially radial direction. Through the placement of a large number of multi-inlet cyclones in parallel, a purification element resembling a filter is obtained.

Abstract: The invention relates to a catalyst feeding system fortank containing solid catalyst mixed with a carrier fluid. The tank system comprises a cylinder tank and a float (1) slidable in the cylindertank, and the catalyst mixture is fed into and dosed out of the cylinder tank on one side of the float. The cylinder tank is provided with a radar level gauge (8) for determining the position of the float (1) in the cylindertank. By means of the radar level gauge, the position of the float and thus the dosing of the catalyst can be measured reliably.
