Pure water (water) Vapor stream (inert, Soy, water) Part 1: Sulfur dioxide (SO2) is a toxic gas emitted by the burning of fossil fuels, and must be removed from stack gas in order to comply with environmental regulations and minimize negative health impacts of this pollutant. A counter-current scrubber can help accomplish this. The scrubber operates at atmospheric pressure and 25 C and uses pure liquid water to selectively absorb SO2 from stack gas. The liquid and vapor streams leaving the scrubber are in equilibrium. The liquid stream leaving contains only water and SO2. The gas stream leaving contains inert gas, SO2, and water vapor. The process flow diagram is given at right F Scrubber Liquid stream (S0, water) Stack gas (inert species, so) The volumetric flow rate of the stack gas to be processed is 5.0 L/min and contains 1.6 mol % SO2. Since SO2 is the only component in the stack gas that absorbs in the water, you can consider the other components of the stack gas as inert. At the operating conditions the Henry's Law constant for SO2 is 3.2x104 mmHg/mole fraction. For all parts of the problem, assume that the vapor phases are an ideal gas and the liquid phases are ideal solutions. a) Rewrite and label the process flow diagram with all relevant variables b) Write out all of the equations that need to be solved to determine the unknown variables, list the values of any variables given in the problem statement, and look up any relevant data that you need. You do not need to solve the equations at this stage. c) Perform a degree of freedom analysis to show that there is one degree of freedom for this problem.
