Overview of Catalytic Recuperative Oxidizer

Image
Epcon’s Catalytic Oxidizers destroy toxic Volatile Organic Compounds (VOCs) that are discharged in industrial process exhausts. The catalytic reactor achieves destruction of the organics by the process of oxidation. The catalyst oxidizes the hydrocarbons to carbon dioxide and water vapor at significantly lower temperatures than thermal oxidizers . How the Catalytic Recuperative Oxidizer Works? The Catalytic Oxidizer is designed based on volume of airflow, organic vapor concentrations and desired destruction efficiency. During operation, VOC-laden air is drawn into the system fan and is discharged into the system's heat exchanger. The air is preheated through the tube side of the heat exchanger and then passes the burner, where the contaminated air is raised to the operating temperature. As the VOC-laden air passes through the catalyst, an exothermicreaction takes place as the VOCs are converted to carbon dioxide and water vapor. The hot, purified air then passes on the shell si

Catalytic Oxidizers Vary in Design & Quality

A common misconception is that you've seen one catalytic oxidizer for air pollution, you've seen them all.   The reality is these systems can vary greatly.  In most cases, a control system automatically unlocks the process, energizes the blowers, and purges the system with fresh air prior to igniting the burner and bringing the system up to its optimum operating temperature. Once heated, the air stream laden with VOCs enters the oxidizer's mixing chamber. It's best that a thorough mixing occurs to insure temperature uniformity. Certain basics do apply for all catalytic oxidizers. In general, the catalytic treatment of volatile organic compounds (VOCs) and other air pollutants,   happens over a customized precious metal catalyst bed withing the combustion chamber. During the oxidation process the harmful compounds are broken down to carbon dioxide, water vapor, and usable heat. These relatively harmless byproducts are often released into the atmosphere and the thermal e

A Case for Thermal Deoiling

Image
The Problem A major Air Conditioning company needed an alternate technology for degreasing evaporator fins. They had, until recently, been deoiling metal parts in a conveyorized solvent based vapor degreasing line. The degreasing technology being used over the years to clean these fins was inefficient and additionally costing millions of dollars a year for water, chemicals and the disposal. In aqueous and solvent based cleaning methods there are not only costs associated with purchasing chemicals, but also disposal costs, high operation and maintenance costs and risk management costs. At the same time, the costs of compliance with rules and regulations governing industrial hygiene, safety and the environment was forcing the manufacturing to reevaluate cleaning methods. Epcon had an initial meeting and proposed a Thermal Cleaning technology –a thermal Deoiler. The Process Thermal Deoiling is a process that uses indirectly heated dry air to clean parts contaminated with oils

Epcon’s Technologies is the Bridge Success

Epcon has been in the business of manufacturing, selling, and developing patented technologies relevant to recuperative thermal oxidizers and regenerative thermal oxidizers since 1977, long before Climate Change was widely accepted corporate agenda. But as environmental concerns within ESGs reporting have steadily been mounting, so have the efficiency of technologies our oxidizers and pollution abatement systems.   Our systems rely upon the concept of a chemical reaction – one involving organic hydrocarbons being processed. In this oxidation process, the volatile organic compounds and pollutants within the air stream – are broken down from their original constituents and reformed into new compounds. Heat and oxygen are used to breakdown the hydrocarbons, thus the term Thermal Oxidation. In deciding how to best apply one of our state-of-the-art Thermal Oxidizers into an existing industrial process, complex factors such as volumetric flow, volatile organic compound loading, and conc
