Abstract
A computer program is presented which develops for a multicomponent distillation column a composition and temperature profile as a function of time from initial start-up to steady-state conditions.
The program is written in Kingston Fortran II language for use on an IBM 1620 II machine. It is a Thiele-Geddes type solution, i.e. the total number of plates, feed plate, overhead and bottoms split are specified and the solution gives plate. compositions and temperatures. The material balance at any time is based on the composition at the previous time, increased (or decreased) by the net quantity added and removed as a result of the flows of the vapor and liquid streams to and from the plate. The ratios between the mass fractions interchanged are established by the overall material balance in the column.
The program assumes constant molal overflow and that equilibrium is established on each plate. Equilibrium relationships are calculated from K value data taken from the literature.
