RT-201 Air Stripper System

General

The "VOC in Water" Air Stripper System based on the El Paso Method can aid in the measurement of fugitive volatile materials, which can escape from cooling tower water for example, and can be an indicator for process leaks and will allow plants to conform to laws limiting such emissions.

Description

The RT-201 Air Stripper is based on a standardized method and is the preferred system for reliably testing VOC (Volatile Organic Compounds) in low PPM-concentrations with a FID-analyzer from cooling tower water. It can also be used in a wide variety of other applications where VOC concentrations in water need to be measured. When connected to a Total Hydrocarbon FID-analyzer the RT-201 is a continuous on-line or transportable monitor, which provides the measurement of low ppm concentrations of dissolved solvents in water. This could be from cooling water, industrial waste- water, groundwater, process or rain water run-off. Continuous monitoring is a reliable and effective method to improve the process management for treating, discharging and detecting of dissolved VOCs in water. Compared to the laboratory grab sample analysis method, the technique of continuous on-line monitoring provides cost effective, remote and operator unattended measurement of volatile hydrocarbons in water.

After the RT-201 stripping unit is connected via a short sample line to FIA (Flame Ionization Analyzer), it reliably measures strippable dissolved and dispersed volatile organic compounds in water.

Typical Applications

  • Cooling Towers
  • Condensate Water
  • Holding Ponds
  • Heat Exchangers
  • Waste Water
  • Process Stream Analysis
  • Spray Paint Booth

VOC in Cooling Tower

Water Leaks of volatile hydrocarbons from heat exchangers may emit large amounts of VOC which can cause emissions into the atmosphere or may create a hazard. Continuous on-line monitoring gives an early warning of possible corrosion leaks. Savings in lost product can be substantial.

VOC in Heat Exchanger Water

The continuous monitoring of volatile hydrocarbons in condensate or cooling water gives the possibly earliest warnings for the development of leaks in a heat exchanger.

VOC in Waste Water, Holding Ponds

Drainage run-offs, equipment leaks or spills can be the cause for a build up of volatile hydrocarbons. A VOC analyzer with the Model RT-201 continuously indicates the presence of VOC in such waters. Features:

  • Continuous monitoring means uninterrupted real time measurement of VOCs in contaminated water.
  • Direct measurement does not require any sample pretreatment prior to measurement.
  • Monitoring process with a FID is more selective for the detection of VOC in the presence of physical and chemical interference in contaminated water.
  • Major Applications are Continuous monitoring (or field monitoring) of VOCs in water from cooling towers, cooling water outlets, condensers, heat exchangers, water wells, spray paint systems, extraction water run off, rain water run off.
