Concentrators are used as an emission control device to allow higher volumes of waste gas to be collected
on an adsorbent for future destruction. Concentrators allow the lower concentrated VOC's to be collected
and then exhausted at smaller volumes at higher concentration levels. Generally, concentration levels are
operated around ten times the waste gas concentration, but this value may be increased depending on the
application. Therefore by using a concentrator many regenerative thermal oxidizer systems are allowed to
operate without or with minimal amounts of auxiliary fuel. Concentrators reduce the operating cost by
loading the VOC's at a higher concentration. The reduced concentrated volume from the concentrator
reduces the size of the oxidation equipment.
The ReGen Series uses the thermal oxidizer exhaust heat as a mechanism to thermally swing the
temperature of the adsorbed VOC and boil it from the adsorbent. This cycling occurs after the adsorbent
has adsorbed the VOC's. This has become to be known as a thermal swing regeneration adsorbent
system. It is so named because the temperature is usually swung between ambient and 250F to 350F in
the regeneration process.
VOC's in the waste gas stream are first processed into one
of the adsorption units (two are usually used, but any number
above two may be used), while one of the adsorption beds is
being thermally regenerated. Hot air flows into the adsorber;
this process heats the adsorbent, and thus boils off the VOC.
The condensed VOC vapor may now be processed to the
thermal oxidizer for thermal destruction at a higher
concentration rate and higher inlet temperatures. This process
reduces the amount of auxiliary fuel required to sustain the
set point destruction temperature of the system.
After the VOC's are removed, cooling air from a blower is admitted in place of the heated air. When the
adsorbent has cooled to ambient conditions, the “conditioned” adsorption capacity has been restored, and
the adsorption bed is now considered regenerated. Regeneration equipment may be designed to occur
between one and eight hours depending on the size of adsorption equipment. Regeneration may be at
either a preset time based on the average VOC concentration according to the design parameters or a
sensor which monitors any possible breakthrough conditions. A predictable air flow and concentration
would allow the regeneration to occur at a given time before any possible breakthrough occurs. The
PLC controlled timer will avoid any possible breakthrough emissions. A sensor controls the regeneration
process and monitors the evacuation process until no VOC's are present in the effluent exhaust from the
adsorbent bed to the thermal oxidizer.
Prior to any possible breakthrough of emissions, the PLC based timer should be used as the principal
control mechanism, VOC sensors are used as a failsafe mechanism to sense the process exhaust and
therefore any VOC's which would present themselves to the failsafe sensor would start the regeneration
cycle on the adsorption bed. While in greater concentrations some VOC's may minimally pass through the
adsorption bed before the sensor triggers the start of the regeneration cycle. This amount is trivial and
should not be considered a violation of your permitting requirements. However when an event occurs the
sensor collects the VOC amount and data logs this information for reference use. Both the automated
timer and a sensor should be used. Thermal regeneration becomes more practical when VOC have lower
vapor pressures.
Concentrators allow the size of the purification unit to be reduced by a factor of 10, minimizing investment
and operating costs. On higher flows i.e. 100,000 SCFM the facilities can reduce the cost of equipment to
a 10,000 SCFM RTO system. When evaluating this reduction, the estimated equipment cost for a
Regenerative Thermal Oxidizer with a size of 100,000 SCFM may cost as much as $3,000,000.00 when
compared to a 10,000 SCFM system with a cost of approximately $300,000.00. Should your plant have
higher process streams it may be a practical alternative in reducing operating and equipment costs.
