H2S Analyzer Features

	Accurate & Continuous Analysis Quantitative Measurement of ppb w ppm w thru Saturation Levels Proven On-Line Reliability & Trouble Free Operation Push Button Validation 4-20mA Output RS-232/485 Communication Direct Read LCD Fast Response Time General Purpose or Explosion Proof Specific for H2S Only - No Interferences Approved Vendor by Saudi Aramco for Model 205
Features and Benefits:
üSave on lab analysis costs, unattended online analysis üEconomical: Payout within days by meeting quality control specifications. üEasy: Calibration is virtually never required. A Perm tube is used to generate a known sample to validate analyzer’s proper operation. üSafe: Purge option for explosion proof ratings üAccurate: Grab samples for the lab deteriorate with time, H2S escapes during sampling. The Model 205 measures continuously, eliminating the need for laboratory analysis. üDependable: Sample Transfer Stripper™ for sampling radically reduces maintenance by ensuring a clean, dry sample to the analyzer
Description:
The ability to analytically quantify H2S in light, medium & heavy crude oil is enhanced with the Sample Transfer Stripper (Membrane Technology) and ratiometric colorimetric technologies offered by Analytical Systems International (ASI).   The principle of operation requires a continuous free flowing liquid sample into a heater where the Sample Transfer Stripper (STS) unit separates the liquids from the H2S gas sample.  An H2S free air or nitrogen carrier then sweeps the H2S gas sample to the H2S analyzer for quantitative analysis in ppb w, ppmw, and up to saturation levels. A liquid validation by PermTubeTM  is optional. The detection technology is based on chemically specific density changes.  The lead acetate sensing tape utilized in our analyzers is the only detection method that is absolutely specific to H2S. Optical illumination & detection are integrated for maximum resolution accuracy. Economic payout is increased because of this automated continuous process or laboratory analyzer.
Typical Applications:
Crude Oil Stabilizers The need to accurately measure H2S in crude is critical to ensure proper product specifications and other purposes. The Model 205 continuously measures H2S to ensure product meets specifications without personnel attendance required or costly lab analysis via inaccurate grab samples.
