M. Technologies specializes in the
installation of ammonia-based systems. This is
especially important due to ammonia’s unique characteristics, which
requires careful selection of components and proper installation to insure
safe and optimum operation.
offer a variety of ammonia scrubber units that meet and exceed the
requirements of our customers. The scrubbers vary in size and capacity.
Recovery Unit Operation Overview
gas stream containing ammonia enters at the bottom of the recovery
vessel (through a sparger) and flows upward. The scrubbing liquid
(water) enters via a spray nozzle at the top of the vessel and flows
removal of the ammonia will take place in the fluidized bed. The
bottom portion of the vessel will drain continuously into a
weak solution of ammonium hydroxide is then re-circulated through the
top of the unit for further scrubbing.
temperature of the saturated ammonium hydroxide solution is measured
on the discharge side of the pump. When the temperature reaches the
specified limit, the unit will pump out the saturated solution into a
holding tank for neutralization and fresh water is introduced back in
the recovery system.
disposal of this weak solution (below pH of 10) is not acceptable,
then the solution can be neutralized using Citric Acid, then discharged to the waste treatment facility or contained for
off-site disposal. The neutral solution is ammonium citrate dibasic,
which is a stable, non-toxic salt.
