b- Start Manuel and Faustina adjust the steady state operating conditions of a stripping column to 2.01 atm(gauge) and 145C. A liquid stream consisting of 20.7 mole% n-octane (Cg His) and the balance a heavy hydrocarbon is fed at 2070 mol/hr to the top of a stripping column. The liquid stream is contacted with an upward-flowing gas stream, which enters the columnas pure nitrogen (N2) at 474K and 106 kPa. The residual liquid leaves the bottom of the column containing all of the heavy hydrocarbon and 7.39% of the n-octane entering the column. The exiting gas is in equilibrium with the entering liquid. Determine the following three unknowns. Mole fraction of n-octane in the exiting gas - Ex: 0.158 Total flow rate of the exiting liquid stream = Ex +490 mol/hr Volumetric flow rate of nitrogen entering EX: 1450 L/min 1 Check Next b- Start Manuel and Faustina adjust the steady state operating conditions of a stripping column to 2.01 atm(gauge) and 145C.
