Abstract

The efficiency of the existing air separation plants can be essentially increased at the cost of additional separation of waste fraction. Various diagram designs of nitrogen plants have been considered which allow to carry out the recirculation of a portion of waste fraction through distillation unit and in doing so to increase the degree of nitrogen recovery. Thermodynamic analysis of nitrogen plant diagrams considered has been performed and on the basis of it the most efficient approaches are proposed for new designs and introduction in industry.
