Details : An absorber is used to remove acetone from a nitrogen carrier gas. The

feed, with acetone weight fraction $0\mathrm{.}213,$ enters at a rate of $500k\frac{g}{h}.$ The

absorbing liquid is water, which enters at a rate of $1000k\frac{g}{h}.$ The exit gas

stream is $0\mathrm{.}8wt\%$ acetone and $2\mathrm{.}9\%$ water vapor. The liquid stream

containing water and acetone from the absorber is fed to a distillation unit. If

the distillate product contains $98\mathrm{.}0\%$ of the acetone coming from the

absorber and its weight fraction in the stream is $0\mathrm{.}991,$

Task :a$)$ Draw a detailed flowsheet of the process, identifying all the in$-$ and

outflows.

b$)$ Find the flowrates of the gas and liquid outlet streams from the absorber$.$

c$)$ What are the distillate and bottoms product flowrates?

d$)$ Discuss your results. State whether they are reasonable.

e$)$ Give information about the gas absorption unit operation$($including

references$).$
