22-07-2018·We keep on diluting it till the time the oxygen in the tank is less than 8% by volume. Usually this is achieved with 3-4 air changes. For example, let us say that the tank is of 4000 m3 capacity. This means that when we have diluted the air inside the tank with about 12000 m3 of inert gas, it would have around 8% of oxygen by volume.
