Chemical Engineering Assignment [ Separation Process]

i want the sizing(height, number of trays and diameter) of the absorber column (using water to remove co2 from the incoming raw biogas) and the stripping column( which uses air to strip out the co2 and recycle the clean water to the absorber). For determining the number of trays i need the equilibrium data for co2-water system at 20 degrees celcius and 10 bar. i.e the mole fractions of co2 in liquid and vapor phase to draw my eqilibrium data and the operating line and then calculate the number of stages from there. I am basically sizing a water scrubber (absorber) to remove carbon-dioxide and purify raw biogas. The incoming raw biogas mainly consists of methane, carbon-dioxide and trace of other gases after a preliminary removal of hydrogen sulfide. So in this purification process, i need to size the absorber and stripping tower (tower height, number of trays, tower diameter). The absorber will be using water to lower the concentration of carbon dioxide while increasing the methane content in the biogas and the stripping tower will be using air to regenerate the water which is recirculated back into the absorber. I just need help with steps on how i can proceed with the sizing of the water scrubber. I have looked for the equilibrium data for co2-water system everywhere but i cannot seem to find it. Different books give the data for so2-water,ammonia-water system. Operating temp of the column is 20 degrees celcius and operating pressure is 10 bar. The process is outlined in slide number 22 in the powerpoint under carbon dioxide removal. ONE WEEK DEADLINE AND PLEASE BID REASONABLE . I AM A STUDENT Thanks
