It is envisaged to eliminate these light constituents by distillation . A study of the operating conditions of the process can be done in pseudo-binary: we assimilate the C7 cut to n-heptane and the light ones to ethane. We wish to construct the diagrams [T-x-y] and [x-y], [h-x-y] of the ethane-n-heptane binary under a fixed pressure of 13.78 bars.
