Example of a material balance on a distillation column used to separate two distinct streams, a vapor and a liquid phase. Both streams include recycle components back into the distillation column.

This problem is not correct. You have labeled the 'top-product' as having .98 and .02 composition when the problem states that the vapor leaving the condenser (170kmol/h) is the one with that composition. That changes the whole problem as finding n1 isn't as simple as plug and chug.

The problem is fine as is.  The composition leaving the condenser into the column will be the same composition of the distillate since we are using a total condenser. All the liquid must have the same composition.

Summarized the whole course in one example thanks :)
