The membrane's ability to selectively sorb components allows concentration factors ranging from 10 to 10,000 depending on the compounds, the membrane type, and process conditions chosen. These systems are not readily scaled down to handle low flows or intermittent streams. In the well stripping systems usually pull the VOC's out of the well into above ground strippers and or carbon based absorbers. AMT has engineered membrane based strippers as in-pipe devices suitable for placement either directly in the well, or above ground. The membrane units can remove the bulk of the contaminants with a vacuum source followed by recovery via condensation, catalytic combustion, or carbon absorption of the remaining balance.
Many industrial processes release toxic organic vapors.
These volatile hydrocarbons, fluorocarbons, or other greenhouse gases are often also carcinogenic and contribute to photochemical smog. Removal and recovery of these VOC's from Vent streams can be accomplished with AMT's membrane gas separators. The small permeated gas stream can be readily condensed for recovery, recycle or disposal.
