In the manufacture of methyl ethyl ketone (MEK) from 2-butanol, the reactorproducts are precooled and then partially condensed in a shell and tube exchanger.A typical analysis of the stream entering the condenser is, mol fractions: MEK0.47, unreacted alcohol 0.06, hydrogen 0.47. Only 85 per cent of the MEK andalcohol are condensed. The hydrogen is non-condensable.The vapours enter the condenser at 125ŽC and the condensate and uncondensedmaterial leave at 27ŽC. The condenser pressure is maintained at 1.1 bara.Make a preliminary design of this condenser, for a feed rate of 1500 kg/h. Chilledwater will be used as the coolant, at an inlet temperature of 10ŽC and allowabletemperature rise of 30ŽC.Any of the physical properties of the components not available in Appendix C,or the general literature, should be estimated.
