Description:

The ability to analytically quantify oil in water is greatly enhanced with the Sample Transfer Stripper ( Exclusive 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 for the Model 204 Oil in Water Analyzer 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. Patents and Patents Pending based on letters that are available on request.

Applications include the analysis of oil in water for cooling towers, heat exchangers, holding ponds, run off water, waste water and more.
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 Oil in Water Analyzer easily provides continuous measurement online.

Oil in produced water
The Model 204 Oil in Water Monitor 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.

Fuelds 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.
