Q1. For vessels being filled with liquid, volatile emissions are generated from two sources, as shown in Figure 1. These sources are evaporation of the liquid and displacement of the vapor in the vapor space by the liquid filling the vessel. Railroad cars are being splash-filled with Heptane. The A gal cars are being filled at the rate of one every B hr. The filling hole in the tank car is C inch in diameter. The ventilation rate is estimated at D ft/min. The temperature is E °F and the pressure is 1 atm. Total Source = Evaporation + Displaced Air Liquid Filling Vapor Evaporation Liquid Drum or Vessel Fig 1. Evaporation and displacement from a filling vessel a) Assume suitable displacement term and calculate the concentration of Heptane vapor as a result of this filling operation. b) Recommend the suitable concentration level and concentration range as per industry safety standards with justification.
