ABSTRACT:
Process and apparatus for the preliminary determination of the efficiency of the trays of distillation and/or absorption columns in order to establish the actual tray number of the columns, as well as for those columns the tray number of which was determined thereby. Each column section of different geometry or load is loaded with a set of trays (12) with air water system consisting at least of two trays having identical geometry (13,13a) and one air distributor (14). On the basis of the recognition that each set of trays (12) may be regarded as a cascade consisting of mixers which include series-connected mixers formed from the trays (13,13a), the liquid content of which is mixed by ascending vapor, or gas, in this case by air. The residence time-spectrum of the water soluble non-volatile substance (tracer) admitted into water and conducted to the upper or intermediate tray of a set of trays (12) to be tested, is measured in such a way that on the basis of the measured residence time-spectrum the tray efficiency valid for air-water system and the tray number valid for the separating system of distillation and/or absorption columns can be calculated--instead of estimation--as a result of which overestimation of the exact tray number of the complete distillation and/or absorption units is no longer necessary.
