methanol is fed to a column with a liquid feed fraction with a flow rate of 14460 kg/st methanol and 10440 kg/st water. The q value of this feed is given as 1.12. It is desired to obtain upper and lower products containing 99% mol methanol and 99% mol water, respectively. since the rate of rifling for this process at a pressure of 1 atm is R:1, the;
a) The amount of distillate and sub-product,
b) The theoretical number of shelves required for this column,
c) Find out which shelf the feed should be made from.
