A wet binary gas mixture at a rate of 10 k-mol/h containing 5% A by volume washing in a walled column with a liquid at a rate of 20 k-mol/h at 38 C and 1 bar pressure. The A content of the gas will be reduced to 0.5% by volume. Wet wall column - high heat of absorption due to 322 mm 6 m long steel pipes (tubes) Multi-pipe heat changer. The number of tubes required to achieve the specified absorption. find it. The equilibrium relationship of the system can be given as y*= 0.5 x under operating conditions. Here y and x is the mole fractions of component A in gas and liquid phases. Gas and liquid phases are air and liquid phases, respectively. Assume that they have the physical properties of water at 38 oC. liquid phase units Total mass transfer coefficient in Kx = 2.06 10 -4 k-mol/m2 s can be taken.
