9- When the liquid flow rate in the column is increased, which of the following does not occur. A column packed with 25 mm ceramic Raschig rings is used to absorb sulfur dioxide from the air by scrubbing the gas with pure water at 30 C and 1 atm. The entering gas contains 25 mol % SO2, and the leaving gas contains 1 mol % SO. Pure water is used as the liquid stream at the inlet. The water flow rate is 10 kg/s. The inlet gas stream flow rate is 1000 m/h. The height of the overall gas-phase transfer unit is HOG=0.65 m. The equilibrium relationship at the operating conditions can be expressed as y = 43x NOTE: Perform your calculations using the Wigand simplification. A larger diameter column is required. None All Fixed costs increase. Operating expenses increase A shorter column height is required
