<p>The present invention is directed toward the dampening of concentration variations in fluid streams, especially concentration variations that are substantially sinusoidal, by subjecting such streams to a plurality of backmixing steps whereby such concentration variations are reduced. In one embodiment of the present invention, there is provided a surge drum (10) that is divided into a predetermined number of mixing stages (14,15,16,17), each of which is provided with means (18,19, 20,21) to create a fluid jet stream at substantially the inlet of the mixing stage and baffle means (21,22,23,24) positioned with respect to the respective inlet jet (12,18,19,20) for reversing the flow of the jet.</p> |
