ability to analytically quantify hydrocarbons and volatile
organic compounds (VOCs) in cooling towers, heat exchangers,
holding ponds, run-off water, and waste water with our model
204-V hydrocarbon in water monitor is greatly
enhanced with the Sample Transfer Stripper S.T.S (Patent #
5448922) membrane technology and the tin oxide sensor and or G.C. offered by
Analytical Systems International (ASI). The VOC in water analyzer system
utilizes many patented and exclusive features only available
from ASI. The principle of operation
of the VOC in water monitor requires a consistent free
flowing liquid sample into the Sample Transfer Stripper (S.T.S) unit
that separates the liquids from the VOCs & produces an ultra
clean sample. A hydrocarbon free
consistent flowing air carrier then sweeps the VOCs in a
gaseous form into the iron oxide sensor or G.C. for
quantitative analysis in ppb, ppm, or up to saturation
levels. An optional liquid validation by Perm Tube
(Patent #5,156,334) is available. This unattended on-line
hydrocarbon in water analyzer is economically superior to inaccurate laboratory
analyzers where unstable grab samples result in hydrocarbon
& VOCs
deterioration that produce analytical errors. Downtime is
reduced to less than 10% of the El Paso, TOC or Sparger
methods and the economic pay out is increased because of
reduced product loss. In one case, 12,000 pounds of product
loss per day was quickly identified by this proven and
accurate on-line analytical method.
Shell Global Solutions has awarded ASI "preferred vendor"
status for the model 204-V in cooling tower applications. In
addition,
TCEQ has designated the Model 204 as “Best Available Control
Technology” and “Equivalency” for continuous monitoring of
cooling tower waste water applications, Patent #5,156,334,
5,448,922 & Patents Pending based on letters that are
available on request. |
