Stabilization system for flow of organic phase of the cascade of columns with frequency control of pumps
A.G. GORUNOV, K.A. IVANOV

The operation of the Stabilization system for flow of organic phase of the cascade of extraction columns, which includes the bypass control of the flow rates and levels in buffer tanks with the use of the submersible centrifugal pumps and constant speed actuators. The system of frequency control of the submersible centrifugal pump with adaptive control of the liquid level in the buffer tank was proposed to reduce low-frequency and high-frequency oscillations of the flow rate of the organic phase. The results of industrial tests of the developed system were presented. Key words: extraction cascade, column, organic phase, centrifugal pump, bypass control, frequency control, adaptive system.
