Top 7 Mistakes Made When Buying A Regenerative Thermal Oxidizer
Regenerative Thermal Oxidizers require more knowledge about the aspects of the process stream and therfore there are more mitakes likely to occur.
1. Inexact material for the chemical composition of the waste-gas stream. Choosing materials that are right for the application will promote equipment life and regenerative thermal oxidizerdependability.
A. Skin or Shell Material Selection (Metal Type i.e. Carbon, Stainless Steel, Inconel, Thickness 3/8″)
B. Valve Selection (Poppet Valves vs. Butterfly) Opt for the butterfly valves for their reliability, costs a little more to construct.
C. Heat Recovery Bed Support (Quanity thereof, Material, Thickness) Reinforcement provides a stable ceramic media bed to prevent media breakage.
D. Paint (High Temperature vs. Hot Dipped Galvanized Metal) High temperature paint will have to be applied each year in an effort to prevent rusting out.
E. High Quality Solenoids, Compressors, etc. This is the heart of the valve system, buy high quality.
2. Characterization of the Plant Process Stream.
A. Misrepresentation or making an educated guess of the density of plant waste-off gases. It is extremely important to know the amount of VOC’s, HAP’s or other gases that the regenerative thermal oxidizer system will be processing. This is especially important when the off gases contain halogens or H2S. Specify the amount lbs. per hour or ppmv, allowing for equipment design and assure proper thermal oxidation process.
3. Plant’s required Vacuum Pressure or the amount of VOC’s.
A. This is a very common occurrence in the industry. Either the OEM builds a system to fit a budget as part of the available capitol or the plant tries to get by with less. Either way, when start uo occurs the real problems will begin. Process waste-off gas amount is to great, inadequate vacuum pressure on process line, or the system operates outside design considerations.
4. Sizing the Regenerative Thermal Oxidizer Heat Recovery System.
A. A common problem is when equipment companies size the heat recovery system for normal plant VOC volume and not for high loading or spiking conditions that may exist in the plant from time to time. Often the designer will manufacture a thermal oxidizer system for the average VOC loading condition, only to find that the plant has frequent spike conditions. The regenerative thermal oxidizer system should be able to handle these frequent spikes. These spikes can be addressed by use of a hot air by pass system which operates during these spike phases. Afterwards when normal VOC conditions return the system will again be running at maximum heat recovery efficiency. When spikes in the process flow occur your heat recovery efficiency will not be an issue.
5. Incorrect Heat Recovery Media or Heat Recovery Media Placement.
A. Incorrect media sizing or type can result in system fouling (plugging) or loss in thermal efficiency. Improper media placement can result in inefficiencies by means of the process stream channeling. Proper media size and media protection can protect the media material and give the system better thermal efficiency. Often air pollution manufactures may specify ceramic media that is in stock or readily available and quality is inferior.
6. Improper Plant Particulate Filtration.
A. Poor or lacking maintenance of upstream particulate removal. This is very common issue when the plant maintenance department fails to maintain proper filtration of the plant process gases going to the regenerative thermal oxidizer. Poor filtration or lack of equipment in many off gas processes will result in early media replacement or continual media cleaning.
7. Compliance Testing.
A. Testing the regenerative thermal oxidizer equipment above the permit requirement. Often companies wish to run the system at higher destruction. This is great; however testing above the permit level can cause a new set of problems. You may be required to operate the regenerative thermal oxidizer equipment on an established baseline. After a period of time the thermal oxidizer may be running in compliance with the original permit, but fails to be in the higher baseline due to aging of valve seals or particulate within the media. At this point you may be out of the established baseline compliance.

2pc Professional Tire Valve Core Removal Tool $4.39 The valve core is a critical component of your tires. It’s a small metal spring-loaded device that fits inside the stem; it allows air in when you attach a chuck to inflate the tire and prevents air from escaping during normal operation. Removing/installing the core without the proper tool can easily damage the core and or stem inner-threads and prevent proper functioning – which means you eithe… |
