AIR pollution control specialist AirProtekt
has supplied, installed and commissioned
turnkey air pollution control equipment to
abate VOC fumes and odours from three
solvent based spray painting booths and
baking ovens at an aircraft component
finishing facility.
The Honeycat® concentrator catalytic
oxidation air pollution control and energy
saving system treats the exhaust gases
from the component finishing process
to give a maximum running flowrate of
12,000Nm3 hr-1 at a temperature of 20°C
with a normal VOC concentration of 170mg
Nm-3 MEK, xylene and toluene. The solvent
laden gases are ducted and pulled through
a rotary honeycomb zeolite wheel.
The solvent from the process stream is
adsorbed onto the hydrophobic zeolite in
the honeycomb wheel. The clean gases
are then transported into the main process
fan inlet and pass via an exhaust stack to
atmosphere. The concentrator’s honeycomb
wheel zeolite rotor is continuously rotating
to adsorb the VOCs, which then pass into
the regeneration zone where the VOCs are
removed by a small volume of preheated
air, which then passes into a small Honeycat
catalytic oxidation system.
The combination of the VOC concentrator
and Honeycat catalytic oxidation system
means very large process exhaust flows
containing low quantities of VOCs can be
treated by a cost effective system. This
type of system means that only 5% of the
process flow is treated by the Honeycat
catalytic oxidation system, which represents
a reduction of 20:1. With the increased VOC
concentration the operating cost for the total
system is very low when compared with
alternative systems.
“AirProtekt’s solution to the challenges
posed by this aircraft component finishing
application has now enabled the new
production facility to comply with statutory
emission regulations for VOCs,” explained
Trevor Lawton, AirProtekt’s managing
director. “The new installation also extends
the company’s global environmental policy.
The Honeycat concentrator catalytic
oxidation air pollution control and energy
saving system also benefits from much
lower capital and running costs compared
with an alternative thermal oxidation plant
solution.”
Overall, the AirProtekt is a low energy
solution for both start up and online running
conditions. The compact catalytic oxidation
system also requires only minimal upgrades
to a customer’s infrastructure. The system
features lightweight construction, requires
no compressed air or natural gas, and is
very quiet in operation.
AirProtekt’s engineering solutions are
tailored to address specific local emission
requirements but are also specified to
comply with national and international
regulations as well as detailed global
company-specific guidelines or operational
procedures.

AirProtekt Honeycat and concentrator
Catalytic oxidation system for
finishing facility
OP Srl’s Unispeed USFL 90/37 is a
machine for 37° and 90° orbital flaring of
hydraulic rigid pipe ends with ISO 8434-2
and ISO 8434-3 fitting systems.
Designed to be practical and easy to
use, the machine requires only one tool
change to carry out flaring operations. This
reduces processing time to a minimum,
since it is carried out easily and without
additional equipment. The machine uses
a cold orbital forming process to create a
flat and smooth sealing surface at 90° and
37° with a suitable rugosity for the O-ring
seal. By doing so, it avoids the formation
of processing signs that can occasionally
occur with common axial deformation
processes.
The system is compliant with the pipe
flaring requirements regulated by SAE and
ISO standards. The various adjustment
and configuration possibilities of USFL
90/37 allow any flaring diameter and
thickness. The semi-automatic processing
cycle allows the flaring process to be
fast, and avoids welding or soldering the
clamping ring to the pipe end. The final
cycle lay-up ensures optimal flaring and
finishing results.
