Problem 13.3: The fugacity coefficient of CO2 in liquid n-pentane at 344.15 K, 2.93 bar approaches the value ? = 39.2. Use this information to calculate Henry's law constant for this system. Problem 13.4: A chemical process produces a waste stream that is mostly air but contains dimethlyamine (DMA) at a mol fraction of 0.01. To satisfy emission standards, the gas stream must be purified to contain no more than 100 ppm of DMA. To achieve this concentration, the gas is passed through a liquid scrubber in which water is sprayed from the top of the tank while the gas rises. During the contact between the drops and the gas, some DMA is transferred to the liquid phase. The inlet water contains no DMA and the exiting streams may be assumed to be in equilibrium with each other. The process is operated at 25 °C, 1 bar. a) Calculate the required flow rate of water to achieved the desired purification. Report the result in kg of water per kg of air. b) If the water flow rate must remain less than 50 kg water/kg of air, what is the required pressure? c) Critique the assumption that the exit streams are at equilibrium. Additional data: Henry's law constant for DMA at 25 °C is 1.84 bar.
