Abstract
An apparatus and method for scrubbing or removing ammonia fumes by passing the ammonia vapor through a shower of ammonia-absorbent liquid such as water in a chamber are disclosed in this invention. The ammonia vapors are absorbed by and enter into solution with the liquid, the clean air is discharged into the atmosphere, and the solution of ammonia and liquid is disposed of in an appropriate manner. Preferably, a portion of the solution is recirculated to absorb additional ammonia in the chamber while the balance is discharged; and fresh make-up liquid is added to prevent the solution from becoming fully saturated with ammonia or from losing its effectiveness in the scrubbing process. The apparatus includes a cabinet, air transfer means, a shower chamber and means for producing a dense shower of liquid droplets, liquid circulator and discharge means and control mechanism to maintain absorbent liquid within the system.
