Features and Benefits:

Save on lab analysis costs with unattended online analysis
Economical: Payout within days by meeting quality control specifications.
Easy: Calibration is virtually never required. A Perm tube is used to generate a known sample to validate analyzer' s proper operation.
Safe: Purge option for explosion proof ratings
Accurate: Grab samples for the lab deteriorate with time, H2S escapes during sampling. The Model 205 measures continuously, eliminating the need for laboratory analysis.
Dependable: Sample Transfer Stripperâ„¢ 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 ( Patented Membrane Technology) and ratiometric colorimetric technologies offered by Analytical Systems International ( ASI) . This principle of operation is described in various ASTM methods including D4084-82, D4468-85, and D4045-81.

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. Patents and Patents Pending based on letters that are available on request.

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.
Monitoring for MIC & H2S Cracking.
