The CPI recuperative catalytic oxidizer is designed to treat hydrocarbons, volatile organic compounds (VOC), hazardous air pollutants (HAP), noxious and odorous emissions. No other manufacturer offers you the extensive knowledge - in both oxidizers and catalyst technologies - necessary to achieve the most complete and cost effective elimination of VOC's.

Catalytic Oxidizer Process

CPI designs each recuperative Catalytic Oxidizer based on the exact needs of your application. With 50+ years of catalyst manufacturing as a basis of our expertise, you can be assured that your CPI Catalytic Oxidizer will be designed with the most appropriate enzyme product for your needs. The CPI Catalytic Oxidizer is applied to a broad range of industrial processes. The CPI Catalytic Oxidizer combines a low-temperature oxidation catalyst, our unique primary heat exchanger, and an efficient combustion system all in a convenient integrated package. These systems are easy to install, provide very high removal efficiency, and offer very low operating cost. With zero moving parts in the reactor, the CPI Catalytic Oxidizer provides the highest uptime reliability.

How A Catalytic Oxidizer works

Catalytic treatment of VOC's and other air pollutants works by reacting the harmful air pollutants over a specially designed catalyst where VOC's are converted to CO2, water vapor (H2O), and usable heat. These harmless byproducts are passed through a heat exchanger where the gas streams energy is transferred to the incoming exhaust.

VECTOR Catalytic Oxidizer Process

Catalytic Oxidation Process

The Catalytic Oxidation Process starts by incorporating a booster fan to draw one or more VOC-laden exhaust from your process lines into the system. From there, your process VOC laden exhaust is directed to our unique stainless steel primary air-to-air heat exchanger where energy is transferred to the process exhaust before passing through to the preheat burner. The main heat exchanger can eliminate the auxiliary fuel required for operation.

A pre-heat burner is used to maintain the desired catalyst inlet temperature precisely. The burner is designed to promote mixing of the exhaust gasses with oxygen when fired through our specialized burner plenum. This innovative design provides the highest degree of flame impingement and high-velocity mixing, leading to airflow and temperature uniformity for which the CPI Catalytic Oxidizer is known.

The pre-heated exhaust stream enters the catalyst bed and reacts with any of the specially selected catalysts where an exothermic reaction occurs, leading to complete combustion of the VOC's. The Catalytic Oxidizer can be designed for use with Catalytic Oxidation systems represent cost-effective air pollution control alternatives. The oxidation of hydrocarbons (VOC's) results in harmless byproducts, water vapor, and useable heat. The catalyst induced ionization level for most VOC's occurs at temperatures between 400 F and 750 F. This is sufficient to achieve conversion of VOC/HAP pollutants in excess of 99%.

Here the hot – cleaned exhaust is sent to the primary heat exchanger to give its heat up to the incoming exhaust gas for pre-heating purposes. After the primary heat exchanger, the cleaned exhaust is sent to atmosphere or to auxiliary heating systems such as; secondary air to air recovery, air to water recovery, or directly back to the process in a closed loop direct recirculation process.

Catalytic Oxidizer Integrated Design

Catalytic Oxidizer Integrated Design

Integrating all the major components into one unitized system saves on field installations, improves reliability, and lowers the overall costs of air compliance. The CPI Catalytic Oxidizer utilizes only the highest quality components. From the all stainless steel mixing and combustion chamber, the heavy-duty, heat exchanger, the specialized burner system, to the catalyst system, each component is contained within a well insulated, maintenance-free exterior designed for long life and low costs.



Each CPI Catalytic Oxidizer is custom engineered and built for maximum performance and flexibility. Therefore, the catalyst is selected based on the ability to provide the highest performance and longest life. The catalyst choices can include platinum group metals on a pourable bead or a monolith support. Each group offers individual benefits for each application. For beaded catalyst products, poison-resistant catalyst provides resistance to many common contaminates while low-temperature formulations allow minimal fuel input. The most noticeable advantage about CPI Oxidizer is found in the innovative, split-bed containment system. The catalyst is contained in a specially developed catalyst tray that offers partial catalyst replacement, faster inspections, cross-sectional analysis, and longer life. Monolith Catalyst groups are used for general industrial applications or for specialized emissions such as halogenated VOCs and others.
