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.
