A COMPARISON OF SURFACE ADSORPTION EFFECTS IN MERCURY AND SULFUR ANALYZER SYSTEMS - ISA EXPO 2007: TECHNICAL CONFERENCE, ENVIRONMENTAL & QUALITY CONTROL

About

Regulations developed for the characterization of mercury and sulfur emissions demand sampling and analysis systems that are capable of reliably and reproducibly transferring sample streams containing these active compounds. Sampling system surfaces will be evaluated in the transport and retention of mercury and sulfur compounds. Mercury and sulfur streams are difficult to transport due to activity with and adsorption to ferrous surfaces. Surfaces to be evaluated include 316L grade stainless steel, 304 grade stainless steel and functionalized amorphous silicon-coated 316L grade and 304 grade stainless steel. Industries benefiting from this study will include stack gas sampling, environmental quality testing, refining streams, oil and gas exploration and transport, or any industry transporting or retaining active compounds.
