Single-entry separator with a product recycle

2 Single-entry separator with a product recycle 

The molar fresh feed supply rate to both separators is While this is the actual feed flow rate into the notuecycle separator, the actual feed flow rate into the recycle 

A light component mass balance for the actual feed stream in the recycle separator leads to 

the apparent values indicate a better quality of separation accompanied by a lesser amount of product stream 1. For a better picture, let us compute the extent of separation with recycle and without recycle  

Since all the mixtures are dilute in species 1, we may assume that
