Ammonia scrubber

Mechanism

  • Spray towers are very simple, low-energy wet scrubbers.
  • In these  scrubbers,  the particulate-laden gas  stream is  introduced into a chamber where it comes into contact with  liquid  droplets  generated  by multiple spray zones. 
  • These scrubbers are also known as pre-formed spray  scrubbers, since  the liquid  is  formed  into  droplets  prior  to contact with  the gas stream.
  • The size of the droplets generated by the spray nozzles is controlled to maximize liquid-particle contact and, consequently, scrubber collection efficiency.
  • Spray towers are cylindrical or rectangular chambers that can be installed vertically or horizontally. In vertical spray towers, the gas stream flows up through the chamber and encounters several sets of spray nozzles producing liquid droplets.
  • A de-mister  at  the  top  of  the  spray  tower removes  liquid  droplets  and  wetted  PM from  the  exiting  gas   
  • Scrubbing liquid and wetted PM also drain from the bottom of the tower in the form of slurry. Horizontal spray chambers operate in the same manner, except for the fact that the gas flows horizontally through the device.

Spray Tower applies to all kinds of harmful gases, such as H2S, SOX, NOX, HCL, NH3, CL2, etc. in the following industries

  • The chemical industry, to separate dust and aerosols
  • The metal industry for various types of waste gases
  • Waste incineration installations
  • Gasification processes
  • Potato-processing industry for the removal of starch
  • Glass industry
  • Melting processes in metallurgy
  • Foundries
  • Sintering processes
  • Drying processes
  • Fertilizer production
  • Pharmaceutical industry
  • Plastics industry
