Callidus Tail Gas Thermal Oxidizers –  DRE range of 99 – 99.999, effectively destroying sulfur components found in sulfur recovery unit tail gas. Callidus thermal oxidizer 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 both natural or forced draft are available.

Typical Equipment

  • DeNOx Systems

  • Castable or brick refractory
  • Natural draft/ forced draft
  • Heat recovery (optional)
  • Stack

Typical Waste Streams

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.

Typical Equipment

  • High-intensity burner
  • Brick lined furnace
  • Forced draft
  • Heat recovery equipment
  • Multi-stage process

Typical Waste Streams

  • Ammonia vents
  • Acrylonitrile vents
  • Nitrogen bound organic wastes
  • SWS streams
  • Carbon fiber plant wastes

Typical Installation

  • Petrochemical plant in India
  • 10-60 MM BTU/hr
  • 0 seconds residence time
  • 2200˚F/1600˚F operating temperatures

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 down-fired 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.

Typical Equipment

  • Low emission burner
  • Low porosity brick refractory
  • Forced draft
  • Adiabatic quench
  • Particulate removal
  • Acid Removal
  • Dioxin/Furan Abatement equipment

Typical Waste Streams

  • Ethylene plant blowdown
  • Caustic waste streams

Typical Installation

  • Chemical plant
  • 5 to 150 MMBTU/hr burner firing range
  • 0 seconds residence time
  • 1650˚F-1800˚F operating temperature

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. Either an HCl absorber or a caustic scrubber is used when a small quantity of HCl is present. A two-stage system is often used to reduce caustic usage when the flue gas contains a significantly large quantity of HCl.

Typical Equipment

  • Medium intensity burner
  • Forced draft
  • High alumina brick refractory
  • Heat recovery equipment
  • HCl recovery/scrubber

Typical Waste Streams

  • PVC plant vents
  • VCM waste liquids
  • Pharmaceutical vents
  • Bromine liquid wastes

Typical Installation

  • Chemical plant
  • 10 to 50 MM BTU/hr burner
  • 0 seconds residence time
  • 1800˚F operating temperature
