In a stripping process for the removal of TCA from wastewater (very dilute, 50 mg TCA/L), air is bubbled into the water to transfer the TCA from the liquid phase to the gas phase. This process is carried out at 20 C and 1.25 atm. At 20 C, H- 400 atm when Henry's law is defined by pa H' x xa for the TCA-water system. dilute, 50 water to transfer the T i. What would be the Henry's constant based on the mole fractions of TCA in gas ii. what is the Henry's constant based on the partial pressure ofTCA in the gas iii. If ku in the gas film is 0.01 m/s, what is ko? What is ky? and liquid? phase and the molar concentration of TCA (k mol/m3) in the liquid phase? iv. If k in the liquid film is 0.01 m/s, what is kx?
