Solve Example 17.9 from Textbook By taking SO2 Feed = 8000 kg/h and 98% sulphur recovery. Sulphur in the feed gas is 10% (v/v). Use the same solubility data Example 17.9 Sulfur dioxide produced by the combustion of sulfur in air is absorbed in water. Pure SO2 is then recovered from the solution by steam stripping. Make a preliminary design for the absorption column. The feed will be 5000 kg/h of gas containing 8% v/v SO2. The gas will be cooled to 20 C. A 95% recovery of the sulfur 9814 dioxide is required. 107. 0.05 0.1 0.15 0.5 0.7 1.0 1.5 SO2 % w/w solution Partial press. gas mmHg 0.2 8.5 0.3 14.1 1.2 3.2 5.8 26 39 59 92 Determine the following: Slope of equilibrium line (m) Ratio of y1/y2 = p1/p2 = Optimum Nog (From figure 17.49) Estimation of Column Diameter Gas flow rate = Liquid flow rate = Packing factor Fp = Gas density = FLV = % Flooding = Vw= Column Cross section area (Ac) = Column Diameter = Estimation of HOG Schmidt Number for vapor (SCV) = Schmidt Number for liquid (SCL) = HG = HL = HOG Estimation of the Column Height Z=
