The CS2-air mixture is fed into the absorption column at a flow rate of 52.5 kmol/h, at 30 °C and 1 atm pressure. The partial pressure of CS2 in the incoming gas mixture is 135 mmHg. In order to reduce the CS2 content of the gas stream leaving the absorption column to 0.7%, the washing oil absorption liquid containing 0.2 mol% CS2 is fed to the column at a speed of 220 kmol/h. If the balance equation is ye=2.5xe, find the ideal number of steps using the graphic method.
