Containers with …

… a hygroscopic substance

… a long storage time


Formation of Condensation 1

11

Ambient air enriched with

moisture



12

• Medium is removed from

the tank

• Level drops

• Pressure equalization by

incoming air

→ Inflowing air humidity

according to ambient air!



13

→ Moisture contaminates

substance


Damage as a result

14

• Crystallization and curing

• Clogging of pipes and

nozzles

• High maintenance costs

• Quality loss of the final

product






GIEBEL FilTec GmbH


Problem Solving Adsorber

16

Adsorption of water,

thereby lowering the

humidity and the dew

point.

→ Protection of the

substance contained!


Prevention of Condensation 1

17

Container WITH Adsorber

→ Use of an adsorber with

desiccant



18

Ambient air enriched with

moisture



19

→ No water in the

container!

→ No loss of quality of the

substance

Adsorption

25

• Water molecules are bound in the pores

• Adsorption based on attractions (Van der Waals forces)

• Van der Waals forces are again soluble → Desorption

• Maximum load, until equilibrium!

Air Drying

28

Substance is removed:

Air is sucked in and flows through adsorber

→ absolutely dry air
