Frequently Asked Questions

Will Iono2x "True NTP" systems eliminate all types of odor?

"True NTP" IonO2x Odor Elimination Systems are designed to oxidize low concentrations of odor active Volatile Organic Compounds (VOCs) contained in large volumes of process & building exhaust gas streams. IonO2x systems will eliminate >90% of the odor (as measured by comparison of the before and after treatment samples). To date, IonO2x systems have primarily been used to treat odors from animal feed and pet food processing factories. However, the technology is effective in treating odors associated with tobacco leaf drying and processing, human sewage treatment plant exhaust gases, composting exhaust gases, deep fryers, meat smoking, and VOCs produced from many types of paint and various industrial processes. In all cases, the concentration of VOCs in the gas stream to be treated must be well below the Lower Explosive Limit (LEL) because IonO2x systems produce high temperature electron streamers which can be an ignition source.

How can the effectiveness of Iono2x "True NTP" be verified for specific applications?

The effectiveness of IonO2x "True NTP" Odor Elimination Technology can be verified by pilot testing. There is no charge for the technician's time or the use of the pilot system, but the client is responsible for paying the shipping cost of the pilot system (to and from site), the travel, hotel, meals & car rental for the IonO2x technician. The client is also responsible for paying for odor analysis of before and after treatment samples. In addition to determining the odor elimination effectiveness, pilot tests help determine the amount of energy required to accomplish effective odor elimination/VOC oxidation. This information is then used to size a full scale IonO2x "True NTP" Odor Elimination/VOC oxidation system for the application.

What is the maximum water vapor content in the treated waste stream?

IonO2x "True NTP" Odor Elimination Systems can treat air streams with up 50% water vapor by volume. Typical dryer exhaust gases contain 35% or less water vapor. IonO2x systems perform very well on typical dryer exhaust air applications. IonO2x systems eliminate odor by oxidizing the VOC compounds within the exhaust gas stream. The desired end products of the oxidation reactions for pure hydrocarbon compounds are water (H2O) and carbon dioxide (CO2). (Some VOC compounds are not pure hydrocarbons and as such the end products of the oxidation reaction will not be water and carbon dioxide. This is one of the reasons pilot testing is recommended for new applications, because it allows the total odor reduction possible via IonO2x "True NTP" technology to be verified in advance). Oxidation reactions require "oxygen" as one of the reactant compounds. If the gas stream does not contain any diatomic oxygen (i.e., the waste stream is 99% water vapor and 1% various odorant compounds), there will be no diatomic oxygen available for conversion to rapid oxygen species, and as such, oxidation reactions cannot occur. The upper limit for water vapor concentration for most applications may be much higher than 50%. However, at this time, we are not prepared to state that IonO2x "True NTP" technology will provide effective odor elimination at water vapor concentrations above 50%.

What is the maximum exhaust air temperature that can be treated with Iono2x systems?

Standard temperature IonO2x "True NTP" Odor Elimination Systems can continuously treat exhaust air streams with a temperature of less than or equal to 203 degrees Fahrenheit (95 degrees Celsius). For higher temperature exhaust gas streams, high temperature IonO2x Odor Elimination Systems can be provided, rated to treat exhaust gases with a temperature of 455 degrees Fahrenheit (235 degrees Celsius). Alternatively, the treated gas can be combined with volumes of lower temperature exhaust gas streams (e.g. from coolers or odorous building ventilation exhaust air) to reduce the combined gas temperature that is to be treated with the IonO2x true NTP system. Please consult with our technical staff to obtain a recommendation on how to best proceed with eliminating odor from high temperature exhaust gas streams.

Does the waste gas stream require particulate removal pre-treatment prior to being treated by an Iono2x system?

If the maximum size particle is less than 1/8 inch in diameter and the total dust loading is less than 50 grains per cubic foot, then no dust removal preā€treatment is necessary. In many applications, particulate removal via a properly functioning, standard pressure drop cyclone (with a design pressure drop of 4 to 5 inches of water column) is recommended. If the treated gas stream contains significant volumes of fine powder or dust, then pre-treatment with a reverse pulse jet baghouse or wet venturi scrubber may be required. Please consult with our technical staff to determine whether particulate removal pre-treatment is required.

What system supply voltage is required for Iono2x "True NTP" equipment?

Depending on the system size, IonO2x "True NTP" Odor Elimination Systems operate at various voltages ranging from 120 volt, single phase, to 575 volt, three phase power. Small systems (less than 1500 watts) can be powered at 120 to 240 volts single phase. For larger systems the typical system supply voltage can be 380 volts, 480 volts, or 575 volts, three phase power. The supply voltage frequency can be either 50 or 60 Hertz. Please confirm the system power supply voltage when requesting a system quotation.

What is the typical power consumption for odor elimination applications?

For most odor elimination requirements, IonO2x "True NTP" Odor Elimination Systems will have a power demand ranging from 0.8 watts per CFM to 1.5 watts per CFM of exhaust gas treated. The amount of power actually used may vary depending upon both the concentration and the chemical bond energies of the compounds requiring oxidation. For VOC/odor sources that have not previously used Iono2x technology, pilot testing may be recommended to confirm odor elimination effectiveness and full scale system power requirements.
