Task absorption

Calculate the diameter and height of the absorber nozzle for capturing component A from the air by the absorber B. Also calculate the absorption flow rate in m3/h, if the flow rate of the gas mixture under operating conditions V (m3/h) with the concentration of component A un (%, volume), the degree of capture is  ( % ). The concentration of component A in the absorber B at the inlet to the absorber Xn = 0, and at the outlet is n % of the maximum possible under these conditions, i.e. from the equilibrium with the incoming gas. The equation of the equilibrium line has the form Y* = f(X), where Y[kmol A/kmol of air], X [kmol A/kmol B]. The gas velocity in the absorber w (m/s), the mass transfer coefficient KX [kmol A/(m2 ч h км kmol A/kmol B)], the wettability coefficient of the nozzle  = 0.88. As a nozzle, ceramic Raschig rings with a size of 25x25x3, a pressure in the column P (MPa) and a temperature of 20 oC are used. Give a schematic diagram of the absorber and a Y-X phase diagram. (The initial calculated data are given in Table 3)

Additional information:

The initial data for the 12 options are given in the picture, there are other options available. The solution is made in the Word editor with a set of formulas. The task is performed as part of the control work on buttermilk in Omsk. After payment, we guarantee to receive a file with this task.
