Capture Systems
|
JAMPRO provides:
Capture systems that are used to keep solvent
vapors from becoming fugitive. Our emphasis
is placed on developing capture systems that
will provide the following: 
Use the minimum amount of air to capture the
maximum amount of VOCs.
Minimize interference with operators of the
production equipment.
Contain and capture the VOC vapors at the
source.
JAMPRO conducts studies on Volatile Organic
Compounds (VOCs) and capture systems in surface
coating, printing operations and other industries.
We provide our clients with years of experience
in the following:
Fugitive VOCs
Solvents that evaporate into the production
room and not pulled into the production equipment
are termed "fugitive". They may have a negative
effect on capture efficiency. From a regulatory
standpoint, these fugitive emissions eventually
escape into the atmosphere and become uncontrolled
VOC emissions.
Captured VOCs
Solvents that are pulled into the Production
equipment (e.g. oven dryer) and exhausted
through the stack are said to have been "captured".
These particular solvent vapors are now controlled
and can be exhausted to a VOC reduction device,
if necessary.
Consumed VOCs
Solvents that are oxidized/burned, in the
process, are generally ignored, although the
amount can be significant. For example, some
ovens have been found to burn 5% to 10% of
the solvent present in the re-circulating
air passing through the oven burners. If capture
efficiency is determined by a liquid-vapor
mass balance procedure, the solvent loss by
burning can result in an artificially low
efficiency measurement.
Retained VOCs
Solvent that remains in the final product
are generally called "retained solvent". They
are in most cases such a small amount that
they are frequently ignored when determining
capture efficiencies. Exceptions may be found
in processes which purposely retain significant
amounts of solvent in the product, either
to allow future processing, or to provide
some characteristic that would be missing
in a "bone-dry" product. Still another category
may include that in which the solvent chemically
combines with or within the product.
