A floating roof is used for light products to minimize evaporation losses. If that light fluid is moreover to be kept absolutely dry (methanol, ethanol, MTBE, et cetera) then an internal floating roof tank is used instead of an external floating roof tank so as to avoid any possibility of contamination by rain water.

Hi,
In addition to the reason rightly mentioned by Ping Pong, using IFR instead EFR could be due to controlling the flammable/toxic vapors emission from rim vent/PVRV on the floating roof by upper fixed roof and then conducting them to a safe location...
