Method of optimizing the operation of two or more compressors in parallel or in series. Known methods of this type assume that the compressors are similar and attempt to optimize their operation by balancing the outputs of or the loads on the individual compressors. Although this approach is satisfactory within its limitations, it cannot be employed with compressors that are dissimilar. The new method is intended to ensure economically optimized operation of two or more similar or dissimilar compressors in parallel or in series. The new method is essentially characterized in that the operating points of each pair of compressors are mutually and incrementally displaced without affecting the total operation parameters. The affect of the displacement on the total constraint is monitored. When the variation is occurring in the direction of optimization, it is continued in the same direction. Otherwise, the pressure that the operating points are displaced in is reversed. The procedure gradually shifts the compressors over to the optimal combination of operating points. The new method can be employed to operate any type of compressor in parallel or in series in many technical fields-the chemical industry, the iron-and-steel industry, etc.
