halogenated hydocarbon thermal oxidizer

Halogen-based wastes are an unavoidable reality of the petrochemical and plastics industries. You want them to be treated and eliminated as efficiently and effectively as possible. As a global authority in thermal oxidizer and incineration solutions, Zeeco is uniquely positioned to help you destroy halogenated hydrocarbons— quickly, smoothly and cost-effectively.

Zeeco engineers have extensive experience designing, installing, and servicing Halogenated Hydrocarbon Thermal Oxidation systems around the world. Halogenated Hydrocarbons are those compounds containing chlorine, bromine, fluorine, and iodine. Our solutions thermally treat gaseous and liquid wastes containing halogenated compounds with a proven removal efficiency greater than 99.9 percent.

We offer two primary systems for halogenated waste destruction. Using chlorine as an example, both systems begin with direct fired thermal oxidization followed by downstream removal of the resulting hydrochloric acid (HCl) and free chlorine (Cl2). For smaller systems, removal can usually be accomplished with a single stage caustic scrubber, while larger systems require a two-stage packed column absorber/scrubber for full environmental compliance.

Dynamic testing, dramatic results.

Zeeco’s engineering group goes the extra mile with each and every Halogenated Hydrocarbon System. We use advanced Computational Fluid Dynamics (CFD) modeling to simulate your unique process conditions against actual equipment design. Rather than relying on past experience and traditional design rules, this allows us to predict what cannot otherwise be seen or anticipated. The result? A system that performs better and lasts significantly longer.

Our Combustion Research and Testing facility was the first in the world to become ISO 9001-2000 certified, and our staff stays ahead of rapidly changing emission requirements. With 15 full-scale combustion test furnaces, Zeeco is capable of testing a wide variety of combustion systems under simulated field conditions. A multi-stream incineration system allows us to test the most complex situations in a controlled environment.

Typical Performance

  • Residence time = 2.0 seconds
  • Operating temperature = 1800 to 2200°F (982 to 1204°C)
  • Waste Destruction Efficiency (DRE) > 99.9999%

Typical Applications

  • Vinyl Chloride Monomer (VCM) / Ethylene Dichloride (EDC)
  • Carbon tetrachloride (CCl4)
  • Polyvinyl Chloride Biphenyls (PCB’s)
  • Brominated waste streams

Design Features

  • For small systems involving small amounts of HCl, a single stage caustic scrubber is typically sufficient for environmental compliance.
  • For larger systems, Zeeco recommends a two-stage absorber/ scrubber, where HCl can be recovered as a liquid byproduct.
  • Waste heat recovery can be supplied via a firetube-style boiler integrated between the thermal oxidizer and the packed column.
