Hydrocarbon VOC in Water

Analytical Systems International – Hydrocarbon VOC in Water On-line Analyser

The ability to analytically quantify total hydrocarbons and total volatile organic compounds (VOCs) in cooling towers, heat exchangers, holding ponds, run-off water, and waste water is greatly enhanced with the Model 204 due to the Sample Transfer Stripper (exclusive ASI Membrane Technology) and the tin oxide sensor technologies offered by Analytical Systems Keco. The VOC in water analyzer system utilizes patented and exclusive features only available from Analytical Systems Keco.

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(Exclusive Membrane Technology) 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 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, Patents & Patents Pending based on letters that are available on request.

Applications:

• Hydrocarbons in Cooling Tower Water
Leaks of hydrocarbons from heat exchangers can emit large quantities of Volatile Organic Carbons (VOC). This can be a hazard from a flammability standpoint as well as cause emissions into the atmosphere. On-line continuous monitoring can pay for an analyzer in a short time by warning of corrosion leaks. Savings in lost product and laboratory time can be substantial.

Hydrocarbons in produced water
The Model 204 continuously monitors the discharge of produced water as required by the Environmental Protection Agency (EPA) and other requirements. 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.

Hydrcarbons in Wastewater
Where the dissolved hydrocarbon or oil content could be PPBw, PPMw, or at saturation levels, Model 204 easily provides continuous measurement online. This includes current applications for wastewater effluent monitoring.

Leaks from Heat Exchangers
Monitoring for hydrocarbon in cooling water or condensate allows the earliest warning of developing leaks. Maintenance can be scheduled in advance of costly equipment failure when leakage rate data is used for forecasting purposes. Boiler feed water monitoring for hydrocarbon, from heat exchangers can prevent power generation equipment damage.

Storm Runoff Water
It is required by the U.S. EPA that all storm water runoff be monitored.

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.
