MODEL EVALUATION FOR MASSTRANSFER OPERATING LIMITING BEHAVIOR OF TECHNOLOGICAL PROCESS

The structure of model for the description of mass-transfer operating limiting behaviors of technological process proceeding in rectification columns is offered. These processes are characterized by excessive ablation of a liquid on overlying steps of division and decrease of mass-transfer efficiency. The model basis is made by nonlinear algebro-differential system, considering a division stage efficiency reduction because of liquid ablation.

Keywords: mass-transfer processes, rectification column, operating limiting behavior, stage efficiency.
