D. interface gas phase liquid phase all 'a', 'b' & 'c' _column is used in gas absorption process. A. Wetted wall B. Seixe/perforated tray C. Bubble cap D. Packed 26. Absorption (liquid-gas system) with evolution of heat as compared to isothermal absorption results in decreased solute solubility. large minimum liquid to gas (L/G) ratio. large number of trays. all (a), (b) and (c). Which of the following is not fixed by the process requirements, in the design of absorbers ? A. Flow rate of the entering gas. B. Composition of the entering liquid. C. Terminal concentrations of gas stream. D. None of these. A. B. C. D. Pick out the wrong statement: A. Absorption factor is constant, when the equilibrium and operating lines are straight. B. In case of a stripper, the equilibrium curve is always below the operating line. C. In case of an absorber, the operating line is always above the equilibrium curve. D. In the absorption of low solubility gases, the liquid film is the controlling resistance. Pick out the wrong statement A. Co-current absorbers are usually used, when the gas to be dissolved in the liquid is a pure substance. B. In case of gas absorption, HETP is equal to HTU, when both the operating line & the equilibrium lines are parallel. C. Hatta number is important in case of gas absorption with chemical reaction. D. In actual practice, absorption is an en-dothermic process, while stripping is an exothermic process.
