The vapor leaving the top of a distillation column goes to a condenser in which either total or partial condensation takes place. If a total condenser is used, a portion of the condensate is returned to the top of the column as reflux and the remaining liquid is taken off as the overhead product (or distillate). Vapor from top of column Reflux (liquid) PARTIAL CONDENSER Cooling fluid Overhead product (vapor) REFLUX DRUM If a partial condenser is used, the liquid condensate is returned as reflux and the uncondensed vapor is taken off as the overhead product. The overhead product from an n-butane-n- pentane distillation column is 93 mole% butane. The temperature of the cooling fluid limits the condenser temperature to 39 C or higher. Using Raoult's law, estimate the minimum pressure at which the condenser can operate as a partial condenser (i.e., at which it can produce liquid for reflux)

If a total condenser is used, a portion of the condensate is returned to the top of the column as reflux and the remaining liquid is taken off as the overhead product (or distillate).

The overhead product from an n-butane-n- pentane distillation column is 93 mole% butane. The temperature of the cooling fluid limits the condenser temperature to 39 C or higher.
