Question: The plant has a methanol storage tank with a capacity of 2 x 106 liters. The average temperature of the liquid in the tank is 40oC. The remainder of the tank is filled (padded) with nitrogen at 1 atm absolute to reduce the explosion hazard. This nitrogen can be assumed to be saturated with methanol vapor. The volume of liquid methanol in the tank increases from 800,000 to 1,200,000 liters twice a day, and, in the process, expels nitrogen from the tank. How much (kg/day) methanol would be emitted to the atmosphere if there is no emission control device on the tank? Propose two different schemes to reduce these vapor emissions.  Edit
