Regenerative Thermal Oxidizer Design

This voc abatement technology utilizes ceramic media packed into vertical canisters as a high efficiency heat exchanger.

Regenerative thermal oxidizer design.

A regenerative thermal oxidizer utilizes a unique regenerative style heat exchanger. The basic rto design concept. A regenerative thermal oxidizer rto is a piece of industrial equipment used for the treatment of exhaust air. They achieve emission destruction through high temperature thermal oxidation a process that employs a combination of temperature residence time turbulence and oxygen to convert pollutants into carbon dioxide and water vapor.

A regenerative thermal oxidizer also known as an rto is a type of air pollution control equipment designed to decompose volatile organic compounds vocs hazardous air pollutants haps and other airborne solvents into innocuous co 2 and water vapor by heating the exhaust air to a very high temperature over 1400 f. The ship shore regenerative thermal oxidizer rto converts volatile organic compounds vocs into carbon dioxide and water. It then uses this captured heat to preheat the incoming process gas stream and destroy air pollutants emitted from process exhaust streams at temperatures ranging from 815 c 1 500 f to 980 c 1 800 f. Heat recovery may either be recuperative or regenerative.

The percentage of heat recovery in the design of thermal oxidizers generally increases with decreasing inlet voc hap concentration. Designed to reduce complexity the cleanswitch regenerative thermal oxidizer rto provides cost effective benefits with its flexible modular design. The epsilon regenerative thermal oxidizer rto from dürr megtec is a modularized multi canister thermal oxidizer offering a highly flexible design that makes it appropriate for many applications where volatile organic compounds vocs and hazardous air pollutants haps must be managed and odor control requirements must be met. In recuperative heat recovery heat is recovered by passing the hot exhaust gases through a non contact air to air heat exchanger to heat the incoming air to the oxidizer.

The system is a type of thermal oxidizer that uses a bed of ceramic material to absorb heat from the exhaust gas. Units up to 65 000 scfm are supplied. This heat exchanger is comprised of ceramic material which can come in the form of saddles or honeycomb blocks. Regenerative thermal oxidizer rto regenerative thermal oxidizers from the cmm group are designed to destroy air pollutants emitted from process exhaust streams at temperatures ranging from 815 c 1 500 f to 980 c 1 800 f.

Regenerative thermal oxidizers destroy voc emissions by creating a chemical reaction within the air pollutant and oxygen at elevated temperatures. These regenerative heat exchangers can achieve considerably higher thermal efficiencies than a shell and tube or plate style. This reaction destroys voc emissions in the air stream by converting them to gas water and heat. Three critical interdependent factors control the rate of reaction.
