STORAGE TANKS

storage_tanks

Humidity air results in cooling tanks for condensate and thus to considerable degradation of the substance contained. For example, biological fuels create bacteria, algae, mildew and sulfuric acid by moisture thats leading to the destruction of the tank. For the ventilation of tanks GIEBEL has developed special tank vent dryer. Humidity air is dried and filtered.

The tank can breathe and dry supply air ensures a constant quality of the storage medium. With the right accessories also without vapor return during the filling, overpressure can be successfully avoided.

FORMATION OF WATER IN STORAGE TANKS

Ambient air enriched
with humidity
-> medium is taken from the tank
-> level decreases
-> pressure compensation by incoming air

-> incoming air
air humidity corresponding
ambient air!
Tank is refilled

pressure compensation by
escaping humid air
Cooling of the
ambient air below
dew point

-> formation condensed water inside
-> droplets form and
water flows into the
storage medium

FUNCTIONAL STORAGE TANKS - HUMIDITY AND DEW POINT

Remove the storage medium from the tank

inlet of
moist supply air into
the tank!
absolute humidity
content of water vapour
relative humidity
percentage of maximum humidity

water content:
at 25°C and 90% RH -> 20.7 g/m³
at 20°C and 80% RH -> 13.8 g/m³
at 15°C and 60% RH -> 7.7 g/m³

DAMAGE CAUSED BY WATER

Diesel-Pest
Clogged filters
Quality reduction of the medium
Destruction of the storage medium and refilling

AVOIDANCE OF WATER IN THE STORAGE TANK

Tank WITH Adsorber

-> Use of an adsorber
with desiccant
Ambient air enriched
with humidity
-> medium is taken from the
tank
-> level decreases
-> pressure equalization by
incoming air
-> moisture is separated

-> incoming
air humidity towards 0%rh!
-> tank is filled again

-> pressure compensation by
outflowing dry
air
Cooling of the
ambient air below
dew point

-> no condensation water in the
interior
-> no water drops
-> no water in the medium

Adsorber lowers the air humidity to below 2%RH
and the dew point to below -40°C
Humidity after Adsorber
average 10% rH
Content of water: 1,7 g/m³
Dew point: -12,5°C

MOUNTING ADSORBER

combined unit:
adsorber with venting system as combined unit on the venting pipe
Single installation:
Adsorber at working height next to the tank (possibly inside the building) and venting system outside on the vent pipe
