Solve step by step, please. (Destillation and Extraction).

The supply of hydrocarbons to a distillation column is at its bubble point at 300 psia with molar fractions: C 2=0.08,C3=0.15,nC4=0.20,nC5=0.27,nC6=0.20,nC7=0.10. Determine: (a) The column pressure and condenser type, if the design indicates that if the equipment pressure at its point of spray is
