Water Analyzers

Product Details:

The ability to analytically quantify total hydrocarbons and volatile organic compounds (VOCs) in cooling towers, heat exchangers, holding ponds, produced water, run-off water, and waste water is greatly enhanced with the Model 204 Hydrocarbon VOC in water analyzer due to the Sample Transfer Stripper, utilizing exclusive KECO Membrane Technologies, and the tin oxide sensor technology offered by KECO.

The VOC in water analyzer system utilizes patented and exclusive features only available from KECO.

It measures aliphatic and aromatic hydrocarbons (including important carcinogenic compounds BTEX like benzene, toluene, and xylene).

This hydrocarbon analyzer is very low maintenance and does not require routine calibrations in the field. It is field-proven to maintain a typical 99% up-time.

The liquid sample continuously flows into the analyzer and into the heated Sample Transfer Stripper unit which effectively strips the VOC hydrocarbons from the water and into the carrier air based in part on Henry’s Law. The carrier air then sweeps the VOC hydrocarbons to the metal-oxide sensor or G.C. for quantitative analysis in ppb, ppm, or up to saturation levels.The advanced transmitter electronics quantifies and displays the values on the back-lit LCD display, 4-20mA output loop or communicates via RS-485 Modbus.

Remote and Web based monitoring and control of the analyzer is available.

The optional True Liquid Validation by Permtube offers a validation of the complete analyzer system by introducing hydrocarbons into the analyzer flow path via Permeation Tube. A “bump” up in analyzer’s reading will occur, conveniently verifying proper operation of analyzer without additional equipment.

This unattended on-line hydrocarbon in water analyzer is economically superior to inaccurate laboratory analyzers where unstable grab samples result in hydrocarbon and 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, Chevron and Saudi Aramco have awarded KECO “preferred vendor” status for the model 204 in cooling tower applications.

In addition, TCEQ (the “Texas EPA”) has designated the Model 204 as “Best Available Control Technology” and “Equivalency” for continuous monitoring of cooling tower waste water applications. Patents and Patents Pending based on letters that are available on request.
