# Operating line and equilibrium line in absorption

- - 5. The construction of the two operating lines and the q-line is performed in Excel as follows: 1. 0 percent is to be absorbed, and the concentr mole percent acetone. 1) operating line lies below the equilibrium line. . There are three important elements in an operating dia- gram: the equilibrium line, the operating line, and the tie lines. 0 mol % ammonia. Operating lines and equilibrium curves for the absorption process at 40°C and the desorption process at 110°C of the 60w% IL solution. . . 5. The entering gas contains 30 mole percent acetone, and the entering oil is acetone free. 15a. com. . . The intercept of the rectifying lie on the y axis is, xD/(R+1) = 0. Below the operating line G. . Of the acetone in the air 97 percent is to be absorbed, and the concentrated liquor at the bottom of the tower is to contain 10 mole percent acetone. lie on the equilibrium line. 05 0. I only b. 6. . . . , 4) line can be either above or below the equilibrium curve. . e. Tiller-Tour Equation simplified Kremser-Brown Absorption equation Operating Line (1) Y1. 16. Equation of the operating line of the absorption for real compositions in gas and liquid:. 1 xN. 5-2), at the bottom concentrated end tray, the slope my or tangent at the point X1 on the equilibrium line is used. For the following conditions, determine the number of equilibrium stages required for countercurrent flow of liquid and gas,. A gas stream containing 8 mol% species A is sent to an absorption column (operated at 10 atm) that uses water as absorbent. In case of Absorption system the equation used is : 10. . In absorption and desorption the potential for the mass transfer is determined by the deviation from the phase equilibrium (Figs. expresses liquid and gas ratio: ( ) 1,2 GS LS S S m m g G L Fig. The operating line can be plotted on an arithmetic graph along with the equilibrium curve as shown below The operating line must lie above the equilibrium line in order for absorption to take place. 013 x 10 5 Pa pressure. 0. Assume for both operating lines that x in = 0 and x out = 0. Exercise 1. . 013 x 105 Pa pressure, where water containing 0. . In each tray, the liquid is brought into intimate contact of gas and equilibrium is reached thus making an ideal stage. 0204 0. 34 steps (analytical). On each stage, the liquid and vapor streams are in VLE, so the stream has a liquid composition and a vapor composition. 1. . from line DE to DF. Separation methods by property. . . Vapor mol fraction. Assuming that the water flow rate is 120 times the gas stream flow rate, constant molar overflow (CMO), and linear equilibrium line in the composition range of interest, use the graphical method to determine the number of. Under the influence of these factors mentioned above, the effect of flow rate of rich solution on the RHD is not significant. . . met_scrip_pic ge washer lid lock bypass 3 wire. y>
