The feedstock simulated in this process is a binary mixture of butane (40%) and pentane (60%). Most educational programs use propylene glycol, water, or red dye to simulate these feed mixtures. Flow rates are controlled to the distillation column at 200 gallons per minute (gpm) or hour (gph).

During the dyeing processes, the concentrations of dye in the liquor and on the fibre surface at a particular point at any time may not be at equilibrium with each other a dynamic model is therefore required which represents the time dependency of the concentrations of the dye on the fibre surface. To simulate the textile dyeing processes of various systems it is desirable to build a general expression describing the relationship between the amount of dye adsorbed on the surface of the fibres and the amount of dye remaining in the liquor.
