ABSTRACT:
A control system for blending a rich stream with a diluting stream to obtain a blended stream comprises obtaining values for specific gravities of the rich and diluted streams, a ratio of densities of primary and secondary components in the rich stream and value corresponding to the concentration of primary component in the rich and the blended streams. Additional elements are utilized to obtain actual volumetric flow rates for the rich stream as well as the specific gravity of water in the rich stream and the diluting stream. An algorithm is utilized to manipulate the foregoing values and obtain a desired value for the diluting stream volumetric flow rate and control the flow rate accordingly.
