A 3.00 x 104 -liter storage tank was taken out of service to repair and reattach a feed line damaged in a collision with a tanker. The tank was drained and then opened several days later for a welder to enter and perform the required work. No one realized, however that a large volume of liquid nonane (C9H20) remained in a collection sump at the bottom of the tank after the draining had been completed. Nonane has a lower explosion limit of 0.80 mole% and an upper explosion limit of 2.90 mole%* (i. e., nonane-air mixtures at 1 atm can explode when exposed to a spark or flame if the nonane mole fraction is between the two given values). Use the Antoine equation to estimate the temperature at which the system would have to equilibrate in order for the gas in the tank to be at the lower explosion liimit (P=1 atm).
How many liters of liquid nonane would be required to evaporate in order to meet the lower explosion limit?
Use the Antoine equation to estimate the temperature at which the system would have to equilibrate in order for the nonane in the tank gas to reach a mole fraction of 0.012?
