ABSTRACT:
Hydrogen sulfide scrubber for use with sulfur compound analyzers effectively removes hydrogen sulfide from gas streams, such as ambient air, without removing substantial amounts of other sulfur compounds, particularly sulfur dioxide. The scrubber employs a bed of silver sulfate, silver nitrate, or silver iodide and operates effectively over wide temperature and humidity ranges without requiring temperature control, with minimal interference from ozone, and operates at flow rates employed by conventional sulfur analyzers without excessive pressure drops.
