VOC Thermal Oxidizer

Virtually maintenance-free elimination of
Volatile Organic Compounds in exhaust gasses
Despatch’s VOC Thermal Oxidizer was designed to eliminate over 99%
of Volatile Organic Compounds (VOCs) from gasses exhausted during
the drying step of solar cell manufacturing.
The solar cell manufacturing process creates unwanted environmental
pollutants which are byproducts of the drying process, and contain the
non metallic ingredients found in the paste material such as ethanol,
Texanol™ and terpineol. These pollutants can condense inside facility
ductwork and create hazardous conditions. Destroying the VOCs using
the Oxidizer eliminates the need to collect and dispose of this waste in a
separate process. The exhaust exiting from the VOC Thermal Oxidizer
contains only small amounts of CO2 and water vapor.
In industries that emit VOCs and have established pollution control
technology criteria, Thermal Oxidizers satisfy Best Available Control
Technology (BACT) and Lowest Achievable Emission Rate (LAER).

FEATURES AT A GLANCE

u

Exhaust contains only CO2 and water vapor

capture or destruction of VOCs including
TA Luft regulation of Germany
Eliminates need for handling and disposal of
waste product collected in VOC condensers
Fits on top of CDF dryer - no additional
footprint required

The operation of the VOC Thermal Oxidizer is based on the
principle of combustion which is the most commonly used
method to control emissions of organic compounds and is
used in a variety of industries. Combustion systems are
simple and have very high destruction efficiency.
The VOC Thermal oxidizer maintains a temperature of
760°C (1400°F) to ensure destruction of all VOCs. The
oxidation process releases heat and thereby contributes to
maintaining the temperature of the oxidizer.
