AMETEK PROCESS INSTRUMENTS PRODUCT DATA SHEET 930 H2S in Sulfur Pit (Tank) Analyzer Insuring safety through hydrogen sulfide (H2S) and sulfur dioxide (SO2) measurement Produced liquid sulfur contains approximately 350 parts per million (ppm) of dissolved H2S and hydrogen polysulfides. Spontaneous degassing results in accumulation of these gases in the head space. If the sweep gas is interrupted, H2S can reach the lower explosive limit (LEL) (approximately 3.25%) creating a hazardous condition. In addition, a smoldering pyrophoric fire can be a source of ignition and monitoring SO2 in the head space warns of this condition. The 930 analyzer samples the vapor space gas using proven ultraviolet (UV) technology. The sampling system has a sulfur knock out at the probe to eliminate entry of excess sulfur vapor or liquid into the system. The sample is transported through an electrically traced sample line to the analyzer. Minimal baseline and span drift The dual beam configuration, combined with the reference measurement, ensures low noise performance with minimal baseline and span drift. Measurements from ppm to percent level are possible. Simultaneous measurement The 930 is a multi-component analyzer that is configured for simultaneous measurement of both H2S and SO2. Hkey benefits • Measurements from ppm to percent level • Output alarms for H2S LEL and SO2 (smoldering fire) • Common design with the 900 (air demand) and 910/920 (stack gas) analyzers • Exceptional baseline stability and sensitivity • Advanced Sulfur Removal (ASR) probe prevents sulfur plugging EH APPLICATIONS • Sulfur recovery units • Liquid sulfur storage • De-gassing FI KEY MARKETS • Refinery and gas processing based sulfur recovery units • Sulfur de-gassing To find out more or request a quote visit our website ametekpi.com
