To handle a light solvent load with optimum efficiency, Glenro developed
this 1800 SCFM catalytic oxidizer. Glenro’s customer uses the system to
destroy a combination of Hexane, MEK, Ethyl Acetate and Toluene present in
manufacturing exhaust. Because the solvent load is only about four pounds
per hour, a catalyst chamber is used to initiate combustion of the VOCs. As
the system reaches operating temperature and the VOCs serve as fuel for
their own destruction, the gas-fired burner automatically throttles back.
Heat from the oxidizer’s exhaust is returned to incoming air, which reduces
operating costs. The result is a very efficient (98% destruction) system
that helps the customer comply with VOC abatement regulations.

Paterson, NJ - As manufacturers nationwide begin to pay closer attention to
VOC abatement issues, Glenro Inc. has developed a new catalytic oxidation
system that destroys solvents in process exhaust with 98 percent
efficiency. The new 1800 SCFM oxidizer system has just been placed in
service, where it destroys a four pound-per-hour load of Hexane, MEK, Ethyl
Acetate and Toluene for a major manufacturer.
The oxidizer system measures twenty feet long by five feet wide by nine
feet high, including the heat exchanger, ductwork, supply blower and steel
skid. The system is built predominantly of heavy-gauge 304 stainless steel,
and is extensively insulated. This oxidizer was custom designed and
manufactured for the customer’s specific process requirements.
Fume oxidation systems are designed to eliminate organic hydrocarbons in
manufacturing exhaust air streams prior to discharge into the atmosphere,
in accordance with federal, state and local environmental regulations. In a
catalytic oxidizer system, solvent-laden process exhaust air is ducted into
the oxidizer’s inlet. The air is preheated through a heat exchanger. It is
then routed through the burner chamber, where its temperature is raised
prior to entering the catalyst chamber. In the catalyst chamber, VOCs in
the exhaust air are burned to harmless by-products of combustion. Catalytic
oxidizers are used where process exhaust solvent loads are low, as the
catalyst allows the VOCs to be destroyed with a minimum of additional
energy. The new Glenro oxidizer system also includes an exhaust heat
recuperation subsystem, which returns heat to the incoming air stream,
further reducing the need for added energy. As the burning VOCs begin to
serve as fuel for their own destruction, the oxidizer’s gas-fired burner
automatically throttles back for even greater efficiency.
Headquartered in Paterson, New Jersey, Glenro Inc. provides process heating
engineering and equipment for a wide range of industries and applications.
Equipment includes hot air impingement dryers, flotation dryers, infrared
predryers and ovens, catalytic and thermal fume oxidizers, and turnkey
coating systems that include coaters, material handling, dryers, oxidizers
and heat recovery. Glenro serves customers through a nationwide network of
sales offices.
