 Using a rectifying tower to purify a binary system. The concentration

Using a rectifying tower to purify a binary system. The concentration of the product (XD,5is, originally 0.9 , we want to increase its concentration (XD) to 0.999 by rising the number of plates. If the reflux ration RD=1.5, and the equilibrium line is similar to the linearity (y=0.4x+0.59) 1) What is the ideal number of plates needed to be added? Ans: 10.48 2) If Murphree efficiency NM=0.7, what is the actual number of plates needed? (Overall efficiency can't be applied) Ans: 15.93
