Use simulation program to solve this Example 6.1 with L' - 270 kmol/h

EXAMPLE 6.1 Recovery of Alcohol. In a bioprocess, molasses is fermented to produce a liquor containing ethyl alcohol. A CO CO2-rich vapor with a small amount of ethyl alcohol is evolved. The alcohol is recovered by absorption with water in a sieve-tray tower. Determine the number of equilibrium stages required for countercurrent flow of liquid and gas, assuming isothermal, isobaric conditions and that only alcohol is absorbed. Entering gas is 180kmol/h;98%CO2,2% ethyl alcohol; 30C, 110kPa. Entering liquid absorbent is 100% water; 30C,110kPa. Required recovery (absorption) of ethyl alcohol is 97%
