Abstract

In this investigation, the dynamics of a reboiler-condenser pair, with the reboiler operating under condensate control, were analyzed both theoretically and experimentally, and the results of the two analyses compared.

The theoretical analysis was performed using the standard method of Laplace transform transfer function synthesis.

The experimental study consisted of a frequency response analysis of the system response to sinusoidal variations of the steam condensate rejection rate.

Two mathematical models were developed, one quite rigorous but extremely cumbersome, the other neglecting all but the most important factors for the sake of simplicity.

The experimental data (in the form of Bode plots) were found to be in good agreement with the simplified mathematical model. The more rigorous model proved to be too difficult of manipulation for a complete analysis.
