Application of Analog Computers for the Measurement and Evaluation of Residence Time Distribution

Abstract

The authors described a measurement and calculation method which enables direct contact to be made between any operational unit and an analog time distribution in the case of absorbers is discussed as an example. In connection with the above, the expressions which became usual in connection in with residence time distribution are modified and transformed in such a way as to obtain quantities everywhere which can be directly fed into an analog computer. An advantageous property of the method is its high speed, because calculation can be carried out simultaneously with the experiments. In addition, any other variable which is convertible to an electric tension can be directly fed into an analog computer. For example, a chromatograph can be directly connected to an analog machine. Accordingly, concerning its technical utilization the method is also universal.
