Condenser Liquid Level Influence in a Cryogenic Distillation Column Operation

Abstract

The behaviour of the cryogenic distillation column at the influence of an external factor has been studied. For this, it was analyzed the non steady state for the column when exist a variation in the control system from the cooling circuit of the cryogenic distillation plant. It determine the fluctuation of the hydrogen level from the cryogenic distillation column condenser. The column has H height and N_T theoretical stages, with the feed stream bicompound mixture of tritium and deuterium. The mathematical model for the simulation of the process is based on the equations of balance on the column, for the stages and for the condenser. The column is operated at total reflux. The variation of the level from condenser was considered as a sinusoidal function. The results were represented in specific diagrams and plots. The results followed concentrations profiles at any moment of time. Each parameter can offer information about the behaviour of the distillation column operated at total reflux with sinusoidal oscillation of the liquid level in condenser.
