A Pueblo's water is contaminated with 1,1,2-trichloroethane (TCA). The environmental manager of the Municipality and his team decide that the most appropriate technology to remove TCA is air stripping, so they hire your company to design a packed tower. The contaminated water has 207 g/L and it is required to meet the treatment objective of 5 g/L and the flow of contaminated water is 0.0131 m3/s. The temperature of the contaminated water is 18 C. The packed tower has the following parameters (provided by the environmental manager): = Tower diameter, d=1.2 m Volumetric flow of air, Qa=0.630 m3/s Packing height, Z=8.8 m Gasket type = Plastic saddles 2". Liquid mass transfer coefficient, kL = 1.97x10-4 m/s Gas mass transfer coefficient, kG = 1.04x10-2 m/s Packing wetted area, aW = 59.2 m2/m3 Air density at 18 C, G=1.21 kg/ m3 Density of water18 C, L=0.9985 g/mL Molecular weight of TCA = 133.41 1) Estimate the Henry constant for TCE at 18 C. 2) Calculate the liquid loading rate in the tower, in units of kg/m2-s. Is it a reasonable value? Explain briefly. 3) Calculate the concentration of TCE that would be expected in the effluent water under the treatment conditions. Is the treatment goal achieved? 4) Estimate the pressure drop across the tower. (Hint: use the Eckert curve). Is the value acceptable? Explain briefly
