4- 25 4.35 a. Overall objective : Separate components of a CH 4 -CO 2 mixture, recover CH 4 , and discharge CO 2 to the atmosphere. Absorber function : Separates CO 2 from CH 4 . Stripper function : Removes dissolved CO 2 from CH 3 OH so that the latter can be reused. b. The top streams are liquids while the bottom streams are gases. The liquids are heavier than the gases so the liquids fall through the columns and the gases rise. c. 100 0300 0700 mol / h molCO / mol molCH / mol 2 4 . . ± . . n 1 0010 0990 mol / h molCO / mol molCH / mol 2 4 bg ± . . n 2 0005 0995 mol / h molCO / mol molCH OH / mol 2 3 ± ± n n 3 4 molCO / h molCH OH / h 2 3 ± / ± n n 5 6 mol N h molCO / h 2 2 ± / n 5 mol N h 2 Absorber Stripper Overall : 3 unknowns ( ± , ± , ± nnn 156 ) Absorber : 4 unknowns ( ± , ± , ± , ± nnnn 1234 ) – 2 balances – 3 balances
