Benefits of Renting vs. Owning Air Pollution Control Equipment
We have a ready to use air pollution control fleet or can design a specialized system for your plant operations. Some of the available systems include:
Granulated Activated Carbon (GAC) Systems, Biological Oxidation Systems, Wet Scrubbers, Regenerative, Catalytic and Direct Fired
Thermal Oxidizers. Rentals range from 6 months to 5 years with flexible options.
|Wastewater Ceramic Media Change-Outs
Wastewater treatment facilities are required to
remove VOC’s contained within the treatment of
water. These facilities introduce water vapor
through large sumps or knock-out tanks to remove
the vast majority of the liquids while sending the
emissions to the regenerative thermal oxidizer
system. The forced air subjected to the regenerative
thermal oxidizer system is saturated with higher
humidity and generally lower VOC content which
consequently reduces heat retention in the lower
areas of the heat recovery bed. Higher humidity
reduces the thermal efficiency of the overall system
and will requires more energy or fuel to sustain the
thermal operating temperature. It is important to
recognize that systems having high humidity will
have higher operating and exhaust temperatures,
so design is an important factor in the systems
overall success. Below we have listed several other
items to reduce operating costs and thermal effects
within the regenerative thermal oxidizer system.
Vertical structured ceramic media reduces clogging and downtime in Regenerative Thermal Oxidizers.
RTO's operate at their highest efficiency when equipped with high-quality structured ceramic media
packing; the structured material within the Heat Recovery Chamber sustains the most favorable
temperature for the oxidation process. Many older Regenerative Thermal Oxidizer systems were
installed with saddle or random packing, these packing’s rapidly become clogged with salts and
siloxane, which cause very costly shutdowns and quarterly clean outs or washouts. We use ceramic
structured packing engineered to resist particulate matter and plugging while increasing system
uptime. Ceramic structured media packing is composed of larger openings which run vertically within in
the Regenerative Thermal Oxidizer bed, eliminating any horizontal surfaces that may create resistance
to vapor flow. This vertically structured construction radically reduces the channeling of vapor and
provides for more efficient contact with the ceramic media surface. This increased effectiveness offers
reductions in fuel consumption with the prospect to increase flow through the Regenerative Thermal
Oxidizer Heat Recovery Chamber over ceramic saddle packing’s. The deficit of horizontal surfaces
also minimizes the packing's ability to entrap particulate matter such as silica powder from the
incoming process air, while reducing the pressure drop across the Heat Recovery Chamber.
After replacing existing ceramic random packed Regenerative Thermal Oxidizer beds with vertically
structured ceramic structured media, wastewater applications will observe a decrease in system
pressure drop of approximating 22% while noticing improved efficiency, resulting in significantly lower
electrical and fuel costs.
American Environmental Fabrication & Supply offers engineering expertise and experience in ceramic
media packing installations and retrofits.
If your application has high silica content, larger 2" ceramic saddles should be used to
mitigate any bed plugging.
