Q: What is an oxidizer?
A: It is a treatment unit (Thermal or Catalytic) that will convert an exhaust gas stream containing volatile organic containments known as VOC's to the products of CO2 (Carbon Monoxide) and H2O (Water). Both are inert and do not harm the ozone layers of the earth's protective atmosphere.
|
Q: What types of oxidizers are available?
A: There are four general types of oxidizers available. They are straight thermal, recuperative, catalytic and regenerative. The selection of which one is best suited for a given application is determined by the flow rate, the concentration of (VOC's) organics in the waste stream, the hours of annual operation, and the process requirements.
|
Q: What is heat recovery?
A: Heat recovery is the method of transferring heat energy, generally in the form of stack gas exhaust, and transferring that waste energy into the process with the purpose of reducing the auxiliary gas input requirements. The goal of recovery is to lower operating fuel requirements.

Q: How can I lower my natural gas and energy bills?
A: Generally, we see that most US process manufacturing plants were constructed in an era when natural gas was so inexpensive that stack gas temperatures are in the 1000F range, so a simple evaluation inspection program (known as an audit) can generally establish where savings are available and some practical engineering can recommend conservation options.

Q: How can I reduce my current NOx (Nitric Oxide) levels?
A: Several technologies exist today to reduce stack NOx levels. The first step is to determine the source. Is it from a fuel combustion source or is it from a chemical cleaning source? One solution is to install a SCR (Selective Catalytic Reduction System). SCR units provide an effective, affordable solution to NOx emissions restrictions for gas turbine and industrial furnace applications. These units function by reacting ammonia with the nitrogen oxides (NOx) to reduce them back to elemental nitrogen. These systems can utilize ammonia in virtually any form, including anhydrous (gas), aqueous (liquid), or by the generation of ammonia from urea (solid or liquid). Another solution maybe to modify the combustion NOx generating source to a lower multi stage combustion design. |
Q: What is MACT?
A: This is an acronym developed from Maximum Achievable Control Technology. This is an emissions standard determined by averaging a given set of reported emission values for a certain industry. This may apply to VOC's (Volatile Organic Compounds), CO (Carbon Monoxide), and HAP's (Hazardous Air Pollutants). |
Q: Where can I get confidential support on modifying my federal or state permit?
A: Over the last 25 years in the environmental air emission business, KEC has developed numerous relationships with a range of experts focused on many of the NOx - VOC - PM - 10 permit applications. Contact us today to discuss your specific situation.
|
Q: Is there a source of natural gas price comparisions available?
A: Yes, KEC can provide a source that will match consumption to a competitive source.
