Project Details:
The founders of this start-up had extensive experience with foil coating, as well as, the control
of emissions from this process. Their experience prior to starting their own company had been
with a thermal recuperative oxidizer that eventually was converted to a catalytic oxidizer.
Their new business would be located in New Jersey, one of the most difficult regulatory
environments in the country. Based on their potential to emit, they were required to
achieve VOC destructions of 95% or greater and less than 50 ppmv Carbon Monoxide. Their
solvent mix varied greatly, but was typically made up of toluene and MEK. The flow rate
was expected to be 12,000 scfm @ 300F from 2 lines with solvent emissions of 50 lb/hr.
The process initially would operate one shift per day until production ramped up to 24/7.
They also may have to locate the oxidizer indoors if the new facility they were seeking
had aesthetic restrictions.
Kono Kogs was recommended to them by a consultant, whom we had worked with recently on a successful
project in New Jersey. The founders were familiar with oxidizers, and were confident in the ability
of a catalytic system to treat their emissions. They had investigated new equipment suppliers but
could not justify this amount of capital on a system that does nothing to increase the bottom line,
and would negatively affect their cash flow.
Solution Provided by Kono Kogs, Inc.
Kono Kogs analyzed the process, solvent levels, initial operating schedule, future operating
schedule, size limitations, and most importantly the performance requirements.
We recommended a 12,000 scfm catalytic recuperative oxidizer with bead catalyst. Although their previous
experience had been with monolith catalyst, a bead catalyst can provide from 10-20 times the poison
resistance of monolith style catalyst. This is important with varying mixes of solvents. The bead
catalyst utilized in this system would provide greater then 20 times the poison resistance of monolith,
and was designed to provide greater than 5 years of catalyst life. Although it had the capacity for
12,000 scfm the catalytic system was small enough to fit into most facility overhead doors. The
system also was projected to run at minimum burner firing rate or actually turn the burner off
during operation due to the high energy release from the combustion of VOC’s in the exhaust stream.
Most importantly the system would provide 97% VOC destruction guaranteed, at a cost of less than
half that of new equipment.
