The use of a qualitative method of control for some process parameters of distillation desalting plants

The advantages and drawbacks of the quantitative (by means of change of the pressure pipeline characteristics or other effects on the liquid flow at constant rotational speed of the centrifugal pump impeller) and qualitative (by means of change of rotational speed of the pump impeller) method of some process parameter control (liquid flow rates and its levels in the apparatus in the distillation desalting plants) are considered. The results of stand and industrial-scale tests of the qualitative method for flow control with nominal flow rate of 1,5 and 230 m3/h are given. It is found out that the use of the qualitative method of control characteristics, to simplify the desalination installation process diagram, sharply decrease power consumption.
