Images of a Dual Stage DESOZONE Odor Control
System
The images to the left are of a DESOZONE dual stage odor
control system. Dual stage refers to the two integrated
scrubbers that are oriented in series. In this particular
system the first stage is alkaline and the second stage is
acid, but they could both be alkaline depending on the
application for the system. In this case the first stage has
been selected for removal of hydrogen sulfide while the
second stage is designed to remove ammonia. The first
photo shows the DESOZONE system under test from the
alkaline scrubber side. You can follow the overall process by
referring to the DESOZONE process diagram.
The second image down shows the two scrubber stages.
The grey PVC pipes are the spray bars. The bottom bars
sprays a dilute solution of sodium hydroxide over the
scrubber packing in the first stage. The top PVC pipe sprays
a dilute solution of sulfuric acid. The spray bars are driven
by pumps on each side of the unit. In the top image you can
see a blue centrifugal at the bottom left hand side of the
system. This is the sodium hydroxide pump. It is located next
to a small rectangular tank that holds the concentrated
sodium hydroxide solution. A pH controller/metering pump
adds sodium hydroxide to maintain the pH of the scrubbing
solution being sprayed over the packing. A similar system for
the acidic stage is employed on the opposite side of the unit.
The blue motor on the top left hand side of the third image
drives the blower. The contaminated air first passes along
the length of the alkaline scrubber on the left hand side of the
DESOZONE unit. When the air reaches the end of the
scrubber it passes through a demister and then is directed
back through the acidic stage of the unit. The air passes
through another demister and the exits through the opening
shown in the picture near the center of the right hand side of
the DESOZONE system. The air is now free of odor and can
be vented to the atmosphere.
The fourth picture shows the inside of the control cabinet. In
addition to the power supply unit and controls, this cabinet
also contains the ozone generator. The ozone is mixed with
the sodium hydroxide the oxidize the hydrogen sulfide and
other species (such as mercaptans). The blue canisters are
air filters for removing oil and particles from a compressed air
stream. The metallic cylinder is an water cooled ozone
generator which converts a portion of the oxygen in air to
ozone. In between the filters and the ozone generating cell
are pressure regulating valves and a membrane type high
pressure air dryer.
