6-39. The air in a 55-gal drum must be flushed and inerted with nitrogen before the drum is filled with a flammable liquid. This is accomplished by placing a nitrogen lance through the hole of the drum reaching to the bottom. A constant flow rate of nitrogen is used to achieve the inerting. a. Show that the concentration of oxygen in the drum is represented by Vac --KQ.C. di where C is the concentration of oxygen in the drum (mass/volume), k is the nonideal mixing factor (0.1

Question
6-39. The air in a 55-gal drum must be flushed and inerted with nitrogen before the drum is filled with a flammable liquid. This is accomplished by placing a nitrogen lance through the hole of the drum reaching to the bottom. A constant flow rate of nitrogen is used to achieve the inerting. a. Show that the concentration of oxygen in the drum is represented by --KQ.C. di where C is the concentration of oxygen in the drum (mass/volume), k is the nonideal mixing factor (0.1 <k< 1), and Q, is the volumetric flow of nitrogen (volume/time). b. Show that the time required to reach a target concentration C, from an initial concentration C, is given by (2) In (C.). c. Estimate the time it will take to inert a drum to 1% oxygen using 75 L/min of nitrogen. Use k as a parameter.
