Dehydration by Air Stripping of Biokem

Dehydration by Air Stripping of Biokem

• An alternative technology to vacuum dehydration
  is dehydration by air stripping (Figure 4), a
  process that removes water as well as gaseous
  contaminants in the oil.

• Not only does it remove free and emulsified
  water, but also dissolved water down to less than
  100 ppm.

4

• Because of its ability to degas, it is also
  suitable for removing hydrocarbons in seal oil
  systems.

• Air stripping works by drawing air or nitrogen
  gas into a stream of heated oil, which mixes in
  and absorbs the water and gasses within the oil.
  The oil/air is then expanded to release the air
  or nitrogen, which takes the impurities with it.

6

• Generally, the water removed will be of a
  reasonable quality, sufficient to allow it to be
  drained off in the normal network without special
  disposal requirements.

• The exhaust air and gasses are also controlled to
  minimize the oil vapour released.

• Just like vacuum dehydrators, cost is an issue
  with air stripping. However, its advantage is
  that it costs less to maintain than a typical
  vacuum dehydrator because it has fewer moving
  parts.

11

• The fact that it can also remove other gaseous
  impurities, as well as dissolved water, makes air
  stripping technology an effective alternative to
  vacuum dehydration.
