AMETEK , PROCESS INSTRUMENTS A PRODUCT DATA SHEET MEASURES: H2S (optional COS and CH3SH) 933 Hydrogen Sulfide Analyzer The 933 is a unique UV-based photometric analyzer system for hydrogen sulfide in natural gas The 933 uses AMETEK's proprietary frontal elution chromatography sampling technique, combined with the exceptionally high-resolution, multi-wavelength 900 Series ultraviolet (UV) optical bench. These combine to provide an accurate, interference-free measurement of hydrogen sulfide (H2S). The result is a unique low-level H2S analyzer that is designed for unattended operation for an extended time period. • Fast response, fast recovery • Ranges from 0-3 to 0-100 parts per million (ppm) • Optional measurement of carbonyl sulfide (COS) and methyl mercaptan (CH3SH) • Direct measure of H2S, no scrubbing Self-recovery Two self-regenerating columns are employed in the 933. While one column is conditioning the gas sample, the other is automatically regenerated. Interference free measurements The 933 utilizes unique, proprietary frontal elution chromatography to separate H2S, COS and CH3SH from interfering components in natural gas. Accurate performance Non-dispersive, dual-beam hollow cathode UV photometric detection of H2S (optional COS and CH3SH) provides accuracy better than ±0.25 ppm. Hkey benefits • Extended, unattended operation • Fully integrated analyzer and sample system • Self-recovery after high concentration H2S events • Fast response time to increasing or decreasing H2S concentrations • Concentration measurements of COS and CH3SH optionally available • No consumables, reagents, or disposables other than zero gas EH APPLICATIONS • Natural gas sweetening • Amine contactor overhead • Natural gas custody transfer stations • Natural gas pipelines • Synthetic natural gas (SNG) • Natural gas blending stations • Carbon dioxide (CO2) purity • Biogas KEY MARKETS • Natural gas • Refining • Chemical and petrochemical • Industrial gas
