Callidus Tail Gas Thermal Oxidizers
Callidus Tail Gas Thermal Oxidizers, with a DRE range of 99 – 99.999, effectively destroy sulfur components found in Sulfur Recovery Unit tail gas. This technology balances desired H2S destruction efficiencies, NOx formation and minimized CO production to meet environmental regulations.
Typical oxidizing temperatures vary from 1200˚F to 1800˚F, with residence times of 0.6 to 1.0 second. System designs for natural or forced draft are available.
Callidus De-NOxidizer System
Thermal oxidation of nitrogen-bearing wastes requires a specialized combustion approach. Single-stage combustion of these wastes can produce NOx emissions more than those allowed by most regulatory agencies. To maintain NOx emissions within acceptable limits, our De-NOxidizer system uses a multi-stage process to destroy wastes with a 99-99.999 DRE range.
Callidus Down-fired Thermal Oxidizers
Callidus Down-fired Thermal Oxidizer systems, with a DRE range of 99 – 99.999%, routinely meet or exceed 99% destruction efficiencies for most waste components. Aqueous or organic waste streams containing inorganic or organic salts require that the Thermal Oxidizer be downfired to prevent the accumulation of molten salts in the oxidizer furnace. Because molten salts tend to destroy refractory, our design minimizes salt contact with refractory lining, which improves refractory life.
Particulate matter emission rates may vary from as low as 10 mg/DSCM to as high as 110 mg/DSCM. The emission rate to some extent determines the type of particulate removal system necessary.
Callidus Halogenated Waste Thermal Oxidizers
Callidus Halogenated Waste Thermal Oxidizer Systems are capable of destruction efficiencies of 99-99.999 percent. Operating temperatures can range from 1500˚F to 2200˚F with residence times of 1.0 to 2.0 seconds depending on the destruction efficiency required.
Callidus Fume Thermal Oxidizers
With destruction efficiencies typically between 99 to 99.99 percent, Callidus Fume Thermal Oxidizers thermally treat organic fumes in air or inert gas streams at temperatures between 1400˚F and 1600˚F.
Callidus Catalytic Oxidizers
Callidus Catalytic Oxidizers can be used in cases where the organic level is low, and the fume stream is free from dust or substances potentially poisonous to the catalyst. Catalytic oxidation is generally carried out at 550˚F to 850˚F and requires substantially less fuel than thermal systems.
Destruction efficiencies greater than 99.99 percent may be required for some organic wastes. This is achieved by operating the oxidizer at a higher temperature with minimal auxiliary fuel. Waste heat boilers or hot oil heaters can be used downstream to recover heat for other plant operations.
Callidus Thermal Oxidizer Burners
Callidus Thermal Oxidizer burners offer high stability, exceptional reliability, low maintenance costs and a range of emissions performance for your thermal oxidation systems. The proven design used in Callidus Thermal Oxidizer burners help provide greater stability and lower NOx emissions. These burners are based on Next Generation CUBL technology, which combines the conventional bluff body eddy zone with stabilization channels, notches, ledges and stagnation zones.
Callidus Thermal Oxidizer Burner Ignition
With proven reliability and stability, Honeywell UOP Callidus Thermal Oxidizer pilots are an integral part of your thermal oxidizer system. Our pilots are ignited in our U.S. test facility before they ship, reducing site problems and helping maintain site schedules. Our latest technology, the Scepter Pilot, is ideal for the challenging conditions including rain and steam. We also offer a portfolio of traditional pilot technologies, so you can select the best solution for your unique needs.
