Design a vertical shell and tube condenser for the duty given in question 12.7. Use the same preferred tube size.

Data from 12.7

A condenser is required to condense n-propanol vapor leaving the top of a distillation column.  The n-propanol is essentially pure and is a saturated vapors at a pressure of 2.1 bara. The condensate needs to be sub-cooled to 45°C.  Design a horizontal shell and tube condenser capable of handling a vapor rate of 30,000 kg/h. Cooling water is available at 30°C and the temperature rise is to be limited to 30°C. The pressure drop on the vapour stream is to be less than 50 kN/m², and on the water stream less than 70 kN/m². The preferred tube size is 16 mm inside diameter, 19 mm outside diameter, and 2.5 m long.  Take the saturation temperature of n-propanol at 2.1 bar as 118°C. The other physical properties required can be found in the literature or estimated.
