    Hi can anyone help with the following question:

    A mixture of 60% w/w methanol and 40% w/w water is separated, from a feed of rate 32 kg s-1, in a distillation column. The distillate product, D, recovered from the condenser contains 99% w/w methanol and the bottoms product, B, from the column contains 96% w/w water. The vapour stream entering the condenser at the top of the column is 35 kg s-1. A portion of the distillate from the condenser is returned to the column as reflux, R, the remainder of the product, D, is withdrawn from the process. Assuming that all the vapour from the top of the column is totally condensed, calculate the:
    (i) mass flow rate of the distillate D and bottoms product B;
    (ii) reflux ratio, R/D.

    Thanks
