VOC Absorption

What is absorption ?

  • Absorption is a mass transfer operation in which one or more soluble components of a gas

  • mixture are dissolved in a liquid that has low volatility

  • The pollutant diffuses from the gas into the liquid

The suitability of gas absorption as a pollution control method is generally dependent on the

following factors

  • Availability of suitable solvent

  • Required removal efficiency

  • Pollutant concentration in the inlet vapor

  • Capacity required for handling waste gas

  • Recovery value of the pollutant(s) or the disposal cost of the spent solvent

Physical absorption depends on properties of the gas stream and solvent

  • Density and viscosity

  • Specific characteristics of the pollutant(s) in the gas and the liquid stream

  • Absorption is enhanced by greater contacting surface, higher liquid-gas ratios, and higher concentrations in the gas stream

2
Blower

  • Extracts gas stream from Tank

  • Creates positive pressure in the scrubber

Scrubber

  • Liquid- Gas interface

  • Extracts VOC and HAPS from gas stream

  • Enriches  liquid absorbent (Plant based lean oir or Diesel Oil

  • Generates “scrubbed” air stream vents to the atmosphere

NanoVapor Vapor Absorption System –VAS- 
versus others

  • When searching for air compliance solutions, there are a number of options that might qualify as a BACT (Best Available Control Technology).

  • Conventional wet scrubbers, carbon absorption systems, thermal oxidation, and flaring—the historically default technologies—are often operationally or economically unviable.

NanoVapor  Patented VAS combines   innovative, non-traditional technologies to meet the challenges of the new, more stringent 21st-century environmental compliance regulations
