Features and Benefits:

üSave on lab analysis costs, unattended online analysis

üEconomical: Payout within days by reducing regenerator steam consumption to ensure spec sweet gas instead of over stripping. Reduce amine loss thru carry-over

üEasy: Calibration is virtually never required. Permeation tubes can be used to generate samples 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 costly and inaccurate grab sampling

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 amine 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 PPBw, PPMw, and up to saturation levels. A liquid validation by PermTube™  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:

Amine Regeneration - Lean & Rich

The Model 205 can be used to ensure optimum H2S/Amine loading to reduce regenerator steam consumption by using lower amine circulation. Energy waste due to over-stripping can be eliminated which means lower operating costs.
