As it was shown in the design set up, the design project contains some parts of typical plant unit operations that could be designed by the given data’s. In this paper the design analysis begins from the distillation column, by collecting data’s such as the vapor liquid equilibrium of the mixture and the physical properties of the mixture from chemical engineering handbooks [Perry].The McCabe Thiele method is used to determine the number of theoretical stages by plotting the operating and stripping line .The column diameter, perforations and tray spacing also designed.
Next, the heat exchanger design was done (U-tube) for heating purpose. By using a steam as a heating media and the type of material of construction, tube side and shell side pressure drops, generally thermal and mechanical designs is done. Similar procedure was followed for heat exchanger two (condenser).

Chapter Summaries
The Introduction chapter sets the context for the design project, outlining the scope of the work and the key data sources used. It highlights the use of the McCabe Thiele method for distillation column design, the principles of heat exchanger design, and pump selection considerations based on Bernoulli's equation. The chapter also emphasizes the focus on practical design solutions while acknowledging the economic cost considerations are not addressed.
The Pre-heater design chapter details the calculation of heat load, steam flow rate, and overall heat transfer coefficient. It describes the selection of pipe materials and dimensions, and the determination of tube and shell side convective heat transfer coefficients.
The Pump selection chapter introduces the use of Bernoulli's equation to calculate the required pump power. It addresses head losses due to pipe roughness, fittings, and heat exchanger pressure drops, and concludes with the verification of the net positive suction head (NPSHA) against the net positive suction head required (NPSHR).
