Gas purification techniques

Condensation

The advantage for the use of a condenser is:

• Well to separate large dirt freight

The disadvantages for the use of a condenser are:

• Cooling water is necessary so that an air cooler or cooling tower must be
  placed
• Variable output at variable gas composition and fluid level

Condensation is mainly applied at wet fragrance charged degassing or at very high solvent concentrations(> 50 g/Nm³). At solvents one will generally concern to cryocondensation.                                                                                                                                           Applications are find in:

• Degassing in feeding sector
• Degassing of indirect installations: these degassing do not exist from with a small quality condensable
  gases so that large of acts the gas volume to treat

Condensation as a preprocessing is also generally used to catch the
largest part from the pollutants. Another technique becomes then come up in series to the standards
or the fragrance embarrassment to raise. These in series technique are then less charged so that the costs
are generally lower.
