Extracted text: Carbon disulfide (CS2) is to be recovered from a gas containing 18.0 mole% CS2, 17.22% O2 and 64.78% N2. The gas is fed to a continuous absorption tower, where it contacts liquid benzene which absorbs CS2 but not O2 nor N2. Benzene (CoHe) is fed to the column in a 2:1 mole ratio to the feed gas. Due to the volatility of benzene, some of it evaporates and joins the exiting gas stream. Given that the gas leaving the absorber contains 2% CS2 and 2% benzene: 1. Draw the flow diagram for the process indicating the process unit and the components of all input and output streams. 2. Calculate the fraction of the CS2 fed to the column recovered in the liquid output stream, the mole fraction of CS2 in this stream, and the fraction of benzene fed to the column lost in the vapor product.
