Method for recognizing liquid drops in flow of gas in direct contact apparatuses e.g. columns, involves measuring capacitance of capacitor, and closing presence or absence of liquid drops in flow of gas based on measured capacitance

摘要

The method involves applying voltage at two electrodes (3a, 3b) of a capacitor (11). The capacitor comprises a dielectric unit. Capacitance (C) of the capacitor is measured. Presence or absence of liquid drops (5) in flow of gas is closed based on the measured capacitance. The measured capacitance is compared with a given capacitance (T). Number, density, distribution, average size and/or maximum size of liquid drops are measured and displayed on an output apparatus. The capacitance of the capacitor is repeatedly measured at regular time interval. An independent claim is also included for a device for recognizing liquid drops in flow of gas.
