In this work we explore association of thermodynamic criterion with total purity of separation and stream product slate in complex distillation column static conditions in ethylene production.The surfaces of first and second criteria were formed in plane stream product slate – bottom reboiler evaporative rate for base rate and composition of supply as well as for changing rate feed.We analyzed surfaces of criteria variation in independent section under the conditions of ranging of stream product slate and bottom reboiler evaporative rate. It is determined that maximum of stream product rate with minor variation of quality can be reached according to maximum of thermodynamic criterion for allowed limit of column work. The characteristic change of criterion total purity of separation differs from characteristic of thermodynamic criterion.
