Regenerative Catalytic Oxidizer
Regenerative Catalytic Oxidizers are designed for plant processes where the waste gas stream
has VOC loading high enough to meet the energy requirement of regenerative catalytic systems for
fuel-free operation. However, VOC’s low enough to make a regenerative thermal oxidizer to costly
to operate. In that case a Regenerative Catalytic Oxidizer may offer the lowest equipment
operating costs.

With the rising costs of utilities, air pollution control manufactures along with industry has a
desire to create a high breed. This has led plant operators and air pollution control equipment
suppliers to seek diverse technologies to reduce operating costs associated with air pollution
emissions.
Although, the regenerative thermal oxidizer (RTO) generally is considered the
most energy-efficient volatile organic compound (VOC) control technology available
, it can
be expensive to operate when handling large airflows and lower volatile organic compound
concentrations.

Recent maximum achievable control technology (MACT) standards promulgated by the
Environmental Protection Agency (EPA) have allowed for emission reduction
as low as 90 percent
for hazardous air pollutants (HAP's)
on some applications (review if your plant qualifies, such as
wood manufactured products). This has opened the door for alternative technologies that typically
achieve higher destruction and removal (DRE) efficiencies in excess of 98 percent.

Regenerative catalytic oxidizer (RCO) is a common alternative to a regenerative thermal
oxidizer
currently used for many types of applications. Both the technologies can be suitable for a
range of applications; however there is marked differences between the two technologies. We will
describe the benefits of using regenerative catalytic thermal oxidizers.

How would you define a Regenerative Catalytic Oxidizer?

The pure definition would be defined as a regenerative thermal oxidizer with a catalyst layer
located within the heat recovery exchange bed
, this layer allows the system to run at a much
lower temperature. These regenerative types of thermal oxidizers may require additional fuel for
operation, however a Regenerative Catalytic Oxidizer reduces operating temperature and provides
substantial savings in fuel costs.
New developments in heat exchange media designs allow for
much lower
technologies, resulting in less electrical usage and smaller fan requirements.

Other advantages in the designs of regenerative catalytic oxidizers are they can be
designed to
operate as both a regenerative thermal oxidizer or regenerative catalytic oxidizer
and be
capable of changing over to either method of treatment.
RCO's provide the ultimate flexibility to
increase the operating temperature if the catalyst has had any degradation or fouling
.

Oxidizing temperatures on the
regenerative catalytic oxidizer vary between 550F to 800F.
Studies are based on system designs with a
minimum destruction efficiency of above 98%.

The lower operating temperatures for regenerative catalytic oxidizers have resulted
in systems
that require no auxiliary fuel
, producing the lowest operating cost. Recent environmental
changes in the level of destruction efficiency may allow you to benefit from these new standards.
These savings will allow you to
reduce operating costs by approximately 50% over standard
regenerative thermal oxidizer units
while maintaining the ability to achieve higher destruction
efficiency and temperatures.
