It was analyzed the behavior of the cryogenic distillation column at the influence of an external factor. So, it was considered the non steady state for the column when exist a variation in the control system from the cooling circuit of the cryogenic distillation plant, which determine the fluctuation of the hydrogen level from the cryogenic distillation column condenser. The column has H height and NT 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 results were represented in specific diagrams and plots. Each parameter can offer information about the behavior of the distillation column operated at total reflux with sinusoidal oscillation of the liquid level in condenser.
