Design a distillation column to separate ethylene oxide from ethylene
oxide water system. In this system a small amount of ethylene and traces of
acetaldehyde and formaldehyde are present. Comparing with the quantities
of the ethylene oxide and water present in the system, the amount of
ethylene and others are negligible. So it is considered as a binary system.
The distillation column operates at a pressure of 1 atmosphere pressure
(absolute). The feed entering is a mixture of 193.18 Kg moles of water,
95.133 Kg moles of ethylene oxide. The distillate is 99.9-mole % pure
ethylene oxide and the residue will contain 0.1 mole % ethylene oxide.
