Hydrogen Sulfide (H2S) in Diesel Process Analyzer

Features and Benefits:

Save on lab analysis costs with unattended online analysis.
Economical: Payout within days by reducing regenerator steam consumption to ensure spec sweet gas instead of over stripping. Reduce amine loss thru carry-over.
Easy: Calibration is virtually never required. Permeation tubes can be used to generate samples 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 and inaccurate grab sampling.
Dependable: Sample Transfer Stripper™ for sampling radically reduces maintenance by ensuring a clean, dry sample to the analyzer.

Description:

The ability to analytically quantify H2S (hydrogen sulfide) in non-volatile liquids, such as naphtha, water, crude oil (light, medium & heavy), and gasoline, are enhanced with the Sample Transfer Stripper S.T.S. (Exclusive Membrane Technology) and ASTM approved radiometric colorimetric technology methods offered by Analytical Systems International.

The principle of operation requires a continuous free flowing liquid sample into a heated oven where the Sample Transfer Stripper (S.T.S) 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, ppm, and up to saturation levels. A liquid validation by PermTube is optional. The detection technology is based on chemically specific density changes. The sensing tape utilized in this analyzer is the only detection method that is absolutely specific to H2S. Optical illumination & detection are integrated for maximum resolution accuracy. The electrochemical detection method is also available. Economic payout is increased because of this automated continuous process or laboratory analyzer.
