A simplified mathematical model is developed for the pressure response to vapor and liquid flow rate disturbances in the bottom of a distillation (or absorption) column in the case of trays without downcomers. Transient responses to step disturbance and frequency functions have been computed for columns with tray numbers up to 100. The responses for small tray numbers, or for more than 15 trays but low frequencies can be approximated by first-order behavior. In the case of high tray numbers resonance effects appear in the frequency response.
