ability to analytically quantify oil in water is greatly
enhanced with the Sample Transfer Stripper (Patented
Membrane Technology) and the solid state sensor offered by
Analytical Systems International (ASI). The analyzer system
utilizes many patented and exclusive features only available
from ASI. The principle
of operation requires a consistent free flowing liquid
sample into a Sample Transfer Stripper unit that separates
the liquids from the VOCs in the oil. A hydrocarbon free,
consistently flowing air carrier then sweeps the VOC
components from the oil in a gaseous form into the solid
state sensor for quantitative analysis in ppb w, ppm w, or
up to saturation levels. An optional patented liquid
validation/calibration by Perm Tube is available. This
unattended on-line analysis is economically superior to
inaccurate laboratory analyzers where unstable grab samples
result in oil 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.
Applications include the
analysis of VOCs and oil in water for cooling towers, heat
exchangers, holding ponds, run off water, and waste water.
Typical Applications
Bilge water discharge monitoring
The International Maritime Organization (IMO) and the U.S.
Coast Guard (USCG) requires all ships over 400 gross tons to
monitor bilge water discharges and are limited by 15 ppm.
The Canadian Coast Guard limits discharge concentration at 5
ppm.
·
Oil in Wastewater
Where the dissolved oil or hydrocarbon content could be PPBw,
PPMw, or at saturation levels, Model 204 easily provides
continuous measurement online.
·
Oil in produced water
The Model 204 can continuously monitor the discharge of
produced water as required by the Environmental Protection
Agency (EPA). The EPA requires that produced water discharge
must contain a concentration of less than 29 ppm oil and
less than 42 ppm grease for a 30 day average and daily
maximum.
·
Oil in Cooling Water and Holding Ponds
Equipment leaks, spills, and drainage run-offs can cause
build-up of hydrocarbon in the water. The Model 204 can give
a continuous online indication of the volatile organic
carbon (VOC) / oil contained in these waters.
·
Fuels in Storm Runoff Water
It is required by the U.S. EPA that all storm water runoff
be monitored. The Model 204 can continuously detect fuel in
water at a concentration 1 ppm or better, including as
dissolved hydrocarbons.
·
Phenol in water
The Model 204 can continuously monitor the cooling water to
detect a leak and prevent a discharge violation
·
Hydroelectric dam sumps
·
Drain systems for fuel oil storage tank area
Includes hydro-carbon storage facilities.
·
Ground water recovery sites
Includes fuel storage and transformer sites.
·
Boiler condensate and power plant cooling water reclaiming
systems
Including integral oil coolers.
·
Intake monitoring for Desalination plants
Water discharge in municipal water treatment systems
Oily water or grease discharges in excess of 15 parts per
million(ppm) is not allowed or surcharged in most municipal
water systems.
·
Engine cooling water
Engine damage can be caused by oil in engine cooling water.
·
Effluent monitoring
After an oil-water separator.
