Catalytic Oxidizers

Callidus Catalytic Oxidizers can be used

in cases where the organic level is low

and the ume stream is ree rom dust or

substances potentially poisonous to the

catalyst. Catalytic oxidation is generally

carried out at 550F to 850F and requires

substantially less uel than thermal systems.

Destruction eiciencies greater than 99.99

percent may be required or some organic

wastes. This is achieved by operating

the oxidizer at a higher temperature with

minimal auxiliary uel. Waste heat boilers

or hot oil heaters can be used downstream

to recover heat or other plant operations.

Tail Gas Thermal Oxidizer

Tail Gas rom Sulur Recovery Units

contains a variety o sulur compounds,

which are destroyed in a Callidus Tail Gas

Thermal Oxidizer. Typical oxidizing

temperatures vary rom 1200F to 1500F,

with residence times o 0.6 to 1.0 second.

System designs or both natural or orced

drat are available.

Generally, regulations require H2S in the

lue gas to be 10 ppmv or less; but in

certain cases, levels as low as 2 ppmv

can be achieved.

Downired Thermal Oxidizer Systems

Thermal destruction o aqueous or organic

waste streams containing inorganic or

organic alkali metal salts requires that the

thermal oxidizer be downired to prevent

accumulation o molten salts in the oxidizer

urnace. Because molten salts tend to

destroy reractory, the Callidus design

minimizes salt contact with reractory lining

which improves reractory lie.

Particulatesentrainedinthefluegasare

removed by either a wet or dry lue gas

clean up system depending on the required

emissions rate. In the Callidus wet system,

salt or ash-laden lue gas rom the oxidizer

irst enters the quench system located

directly below the thermal oxidizer. Here

the hot gas is quenched to its adiabatic

saturation temperature by water injection

or by a Callidus high eiciency submerged

quenchsystem(patentpending).

Then, the saturated lue gas lows through

awetventuriscrubberand/orWESP(Wet

to a packed column scrubber, i required, or

vented to the atmosphere through a stack.

In the Callidus dry system design, lue gas

rom the oxidizer is typically cooled by air

and/or water injection beore being sent to a

baghouse or an electrostatic precipitator or

particulate removal.

Halogenated Waste

Thermal Oxidizer Systems

Callidus has extensive experience in

halogenated organic waste oxidation. The

most common halogen is chlorine. Thermal

oxidation o chlorinated hydrocarbons

produceshydrogenchloridegas(HCl)

and some ree chlorine, which must be

removed. The quantity o HCl in the lue gas

determines whether a single or two-stage

HCl removal system is used. Either an

HCl absorber or a caustic scrubber is used

when a small quantity o HCl is present. A

two-stage system is oten used to reduce

caustic usage when the lue gas contains a

signiicantly large quantity o HCl.

Callidus Halogenated Waste Thermal

Oxidizer Systems are capable o destruction

eiciencies up to 99.99 percent. Operating

temperatures can range rom 1500F to

2200F with residence times o 1.0 to 2.0

seconds depending on the destruction

eiciency required.

Low NOx deNOxidzer Systems

Thermal oxidation o nitrogen-bearing

wastes require a specialized combustion

approach. Single-stage combustion o these

wastes can produce NOx emissions in

excess o those allowed by most regulatory

agencies. To maintain NOx emissions within

acceptable limits, Callidus uses a three-

stage combustion process to destroy these

wastes.

The waste is burned in the irst stage under

substoichiometric, or reducing conditions.

The high temperatures and lack o oxygen

in the irst stage cause the nitrogen-bearing

compounds to orm elemental nitrogen

rather than NOx.

In the second stage, lue gas rom the irst

stage is cooled to approximately 1400F by

injection o water, steam, or cooled recycled

lue gas.

The combustion process is completed in

stage three where the lue gas is oxidized

at a temperature o 1700F to 2000F with

excess oxygen present. NOx in the inal lue

gas typically ranges rom 80 to 200 ppm,

depending on the waste composition. A

destruction eiciency o 99.99 percent can

be achieved or most compounds.
