Özet:

 

The binary system of methanol-tert-buthanol was studied at  atmospheric pressure in a 53-tray, 35 mm inside diameter sieve tray  distillation column.  The column had a vertical thermosiphon reboiler  and an overhead condenser.  During the continuous distillation, the  effect of the reflux flow rate and vapour flow rate to the column as  rectangular pulse input variables were investigated in the frequency  domain.  The experimental rectangular pulse input x(t) and output y(t)  of the column were entered into a Pulse Test Program.  The real and  imaginary roots, log modulus phase angles and steady state gains (K)  were calculated by the program.  Then, Bode plots were drawn.  The  time constants and time delays were calculated from the Bode plots.   The open-loop transfer functions of the top and feed plate were  derived.  The transfer functions and initial parameters of the column  were entered into a commercial simulation program.  The experimental  and simulation results were compared.
