1) MTBE Evaporation (Fick's Law)
An open tank, 12 ft in diameter, contains methyl tert-buytl-ether (MTBE) at 25°C that is exposed to air.
Above the liquid MTBE surface is a stagnant air film 1.00 in thick. If the pressure is 1 atm and the air
temperature is 25°C what is the loss of MTBE from the tank (through vaporization and diffusion into the
air) in Ibs/day?
Specific data and assumptions:
Specific gravity of MTBE at 60°F = 0.740
MTBE vapor pressure at 25°C is 245 mmHg (Note: Check / Confirm this value)
Diffusivity (MTBE in air) at 25°C is 0.0800 cm²/s (Note: Check / Confirm this value)
The concentration of MTBE (above) the stagnant air is negligible (~zero)
How accurate is the solution based on the assumed values provided?
