We love to share our knowledge of thermal and regenerative thermal oxidizers to help business owners and future owners navigate the sometimes confusing world of oxidizers. Below are some of the questions Kono Kogs deals with on a daily basis. If you don’t see what your looking for don’t hesitate to contact us and we will be happy to answer any of your oxidizer questions.
We are buying this new piece of process equipment, do we have capacity in the existing oxidizer or what changes do we need to make to have the capacity?
We can evaluate the existing oxidizer capacity and the requirements of the new process and determine the best approach to upgrade the oxidizer. This could include new heat exchanger media, a larger fan or possibly both. We would also evaluate things like the burner system and combustion chamber size to verify it can provide the required destruction levels.
We changed our process to be more water based and less solvent based and now my oxidizer is burning a lot more gas. Is there anything we can do to reduce the amount of gas used?
Yes, we can evaluate the heat exchanger whether it be metal or ceramic media and determine whether it can be upgraded to more efficient type. Or maybe catalyst could be added in this case. In some cases it may be better to replace the current oxidizer with something more efficient. In that case we can look at our inventory and determine whether we have something that will provide better gas efficiency. If not, we can also recommend something new.
We just did our state emissions test and the capture efficiency was very low. What can we do to get it up to where we need it to be?
We can come in and evaluate the current system by taking flows and readings at certain points of the system. Then we can determine whether the current system is optimized. If it isn’t we can recommend how to do that. If area capture hoods or enclosures need to be added we can recommend that as an option as well. We can also provide these things on a new system.
Our oxidizer didn’t pass the emission test and the state is going to fine us and shut us down. We need some help as soon as possible. Can you help?
Yes we can come out and help to determine what the problem is. Whether it be switching valves leaking; a leaking heat exchanger; poor air flow distribution; or poor catalyst performance. We can do a thorough evaluation and provide a turnkey solution in a short period of time and help to keep you in operation.
Our heat exchanger media is plugging up due to particulate. How do we alleviate this problem and deal with it?
Provide us your particulate description, or send us a sample. We can recommend a cleaning cycle and procedure, new more plug-resistant media, upstream filtering, and/or regular media change outs. A site visit will be needed to fully evaluate the issue.
Our oxidizer is in poor shape can it be repaired?
Our experience is that regenerative thermal oxidizer (RTOs) systems less than 20 years old are good candidates for rebuild/repair/upgrade rather than for replacement. Replacement costs including removal of existing, capital cost of a new system and shipping, ductwork, mechanical assembly, etc. add up quickly making it more cost effective to repair the system, upgrade the PLC, and/or add energy saving updates. Thermal recuperative oxidizer systems on the other hand usually are not cost effective to repair for long term use, but simple repairs may help limp these systems along until a replacement can be budgeted for. Catalytic recuperative oxidizers can be repaired, but the cost of catalyst replacement may justify replacement of the system if the catalyst has a history of contaminating quickly. Contact us and we can visit to make an evaluation. We want long term relationships with our customers so we provide our best evaluation of the total cost of ownership of each option so you can make an objective decision.
Can we install catalyst in our RTO?
We can do a poison test on the catalyst and your process. By doing that test and reviewing your specific process conditions we can determine whether catalyst is both cost effective and whether it will be poisoned in a short period of time.
We have hot spots on the outside of our RTO. Can you fix this?
Yes we have a team of experienced insulators we can bring in and repair your oxidizer.
We are adding a new process line and we are looking for someone to help us with a turnkey approach or maybe just size ductwork to the oxidizer. Can you help?
Yes we can help with either one of these scenarios. We have extensive experience both sizing ductwork for your local contractor to put in or providing entire turnkey solutions.
Our oxidizer is faulting out and it just isn’t reliable, how can we fix this issue?
We can come in and evaluate the controls and make recommendations for changes to alleviate this situation. Your oxidizer shouldn’t be dictating your production.
