3.11.3 Arrangement I

 Gases are both introduced and vented from the top of the tank. This is the simplest arrangement. Gas replacement is by the dilution method. The incoming gas should always enter the tank in such a way as to achieve maximum penetration and thorough mixing throughout the tank. Gases can be vented through a vent stack on each tank or through a common vent main. (See figure 11).
