Regenerative Thermal Oxidation Defined

Thermal oxidation is a means typically used to regulate emissions of Unstable Natural Compounds (VOCs) from process industries. Oxidation of the VOCs happens when sufficiently high temperature (1,four hundred° F.), adequate residence time, and turbulence are present to break the molecular bonds of any hydrocarbon to ultimately convert the hydrocarbon to carbon dioxide and water. With rare exception, thermal oxidation produces no harmful byproducts nor is there any hazardous waste to deal with or dispose of. Though thermal oxidation is an easy process capable of very high VOC destruction efficiency, the fuel consumption and value to heat the VOC laden process could be severe.

A Regenerative Thermal Oxidizer, or RTO, builds on the thermal oxidation working ideas, but at enormously enhanced fuel efficiency. An RTO consists of or more heat exchangers related by a common combustion chamber or zone. The heat exchangers include beds filled with media which will permit air to pass while serving as a mass to store heat. The media material choice, size, and shape can range tremendously and substantially impact the design and utility efficiency of the RTO.

The flow by means of the heat trade beds is reversed at regular intervals to preserve the heat of combustion within the RTO. Depending on the application, as much as ninety five% of the heat combustion may be recovered and recycled representing an enormous fuel financial savings advantage relative to traditional thermal oxidization.

In comparison to each thermal and catalytic oxidation, RTOs have the advantage of the VOC application flexibility and destruction capability of a thermal oxidizer with better fuel effectivity than a catalytic oxidizer, without the risk of poisoning or fouling expensive catalyst.

The 3-bed RTO is just like the two-bed RTO. The VOC laden air stream enters the first heat change bed the place the stream passes directly by the media the place it is preheated in route to the combustion chamber where a burner adds any heat necessary to reach optimum combustion temperature and complete the oxidization process. The bed which was the final inlet bed will always be purged with clean air earlier than changing into the outlet bed. The dirty air from the final inlet bed must be cleaned out in an effort to achieve high destruction efficiency.
