1. Gas absorption with a first order reaction: CO2 is absorbed into a liquid under conditions such that the liquid side mass transfer coefficient is 2 × 10-4 m/s. The diffusion coefficient of CO2 in the liquid is 2 × 10-9m²/s. The interfacial concentration of CO2 can be found using the Henry's law. Henry coefficient for CO2 is 0.0315 bar m³/mol when expressed as p = HC at equilibrium, the C being the concentration in the liquid. The pressure is 1atm and temperature is 300K. Assume that CO2 reacts with a dissolved solute in the liquid with a rate constant of 1s¹. Also assume that the bulk concentration of CO2 is zero. a. Find the Hatta number. b. Find the flux of CO2 at the interface c. Find the flux of CO2 going into the bulk liquid. d. What percentage of CO₂ reacts in the film itself?

Normal butane is catalytically isomerized to isobutane. A fresh feed stream containing pure n-butane at temperature T, is mixed adiabatically with a recycle stream containing n-butane and isobutane, and the combined stream is fed to the reactor, where some but not all of the n-butane in the feed is converted. The reactor effluent is pumped to a distillation column. The overhead distillation product contains primarily isobutane and a small amount of n-butane. The bottoms product, which also contains both species, is the stream recycled to the reactor. The streams leaving the distillation column are at different temperatures. a) Determine the number of degrees of freedom associated with the feed mixer, the reactor, the distillation column, and the entire process. Include all unknown process stream temperatures and process unit heat duties in your analysis. b) Suppose a single-pass conversion of 35.0% is attained in the reactor, the overhead distillation column product contains 88.5 mole…

An inlet water solution of 800kg/h containing 12.0 wt % acetone is extracted with the solvent trichloroethane containing 0.5 wt % acetone in a countercurrent tray tower at 250C. The trichloroethane is essentially immiscible with water up to a concentration of acetone in water of 27 wt %. The exit concentration in the water stream is set at 1.0 wt % acetone. The equilibrium data is tabulated in Table 1.
