A condenser is required to condense n propanol vapour leaving the top of adistillation column The n-propanol is essentially pure and is a saturated vapour at a pressure

A condenser is required to condense n-propanol vapour leaving the top of adistillation column. The n-propanol is essentially pure, and is a saturated vapourat a pressure of 2.1 bara. The condensate needs to be sub-cooled to 45ŽC.Design a horizontal shell and tube condenser capable of handling a vapour rateof 30,000 kg/h. Cooling water is available at 30ŽC and the temperature rise is tobe limited to 30ŽC. The pressure drop on the vapour stream is to be less than50 kN/m2 , and on the water stream less than 70 kN/m2. The preferred tube sizeis 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 118ŽC. The otherphysical properties required can be found in the literature, or estimated.
