Barrel & IBC.

During storage and processing of substances in barrels and IBC containers, moist air from the environment is attracted. This humidity contaminates the storage medium. For example, crystallization occurs with isocyanate, oils become saturated with water, and biological fuels form bacteria and sludge.

Various respiration dryers from GIEBEL can be used to protect hygroscopic substances in barrels and IBCs. Whether upright or horizontal barrels, whether plastic or stainless steel IBCs, whether container breathing or active substance removal – a properly designed barrel ventilation filter ensures dry and clean supply air.

Damage caused by water

  • Crystallization and curing
  • Clogging of pipes and nozzles
  • High maintenance costs

How adsorbers work on barrels & IBC

The following graphics show in 3 steps, what happens inside a barrel or IBC without and with an adsorber when the ambient air is enricht with moisture. Just move the handle over the pictures to see the differences.

Left: IBC without an adsorber. Ambient air enriched with moisture.
Right: IBC useing an adsorber with desiccant. Ambient air enriched with moisture.

Left: When medium is taken from the IBC, the level decreases and pressure is compensated by incoming moist air.
Right: When medium is taken from the IBC, the level decreases and pressure is compensated by incoming air. The adsorber seperates moisture up to 2% rH (10% rH on average).

Left: Moisture contaminates substance in IBC.
Right: Moisture remains in the dessicant of the adsorber. No water in the IBC and no loss of substance quality.

Humidity and dew point

Absolute Humidity
Content of water vapor
Relative Humidity
Percentage to maximum humidity

Example
Temperature = 20°C
Air humidity = 80% rH

Water 13.8g/m³
Dew point 16,4°C

Permissible temperature range = 3,6°C

Humidity after adsorber installation
Average 10% rH
Content of water: 1,7 g/m³
Dew point: -12,5°C
