含丙酮蒸氣的摩爾分數為0.02,所以Y1=0.02/0.98=0.020408163;99%的丙酮被吸收,即吸收率為0.99,所以Y2=0.02*0.01/0.98=0.000204082由於用清水吸收,所以X2=0所以最小液氣比=(Y1-Y2)/((X1*)-X2)=m*回收率=1.75*0.99=1.7325因為吸收劑的實際用量為最小用量的1.4倍,所以實際液氣比=1.4*1.7325=2.4255所以L/V=2.4255又混合氣的摩爾流率為0.03kmol.s-1.m-2,所以V=0.03*0.98=0.0294所以L=2.4255*V=2.4255*0.0294=0.0713097(單位為單位截面積的單位)由L/V=(Y1-Y2)/(X1-X2)=(0.020408163-0.000204082)/X1所以X1=0.008329862Z=(V/KYa)*(Y1-Y2)/Ym 其中V已經表示單位截面積的mol流量Ym=((Y1-Y1*)-(Y2-Y2*))/ln((Y1-Y1*)/(Y2-Y2*))由X2=0得Ym=(Y1-Y1*-Y2)/ln((Y1-Y1*)/Y2) =(0.020408163-0.008329862*1.75-0.000204082)/ln((0.020408163-0.008329862*1.75)/0.000204082) =0.001678443所以Z=(0.0294/0.022)*(0.020408163-0.000204082)/0.001678443 =16.08633666m
