Keywords Ultraviolet, Photometers, Absorption, Process ConULTRAVIOLET ABSORPTION SPECTROSCOPY, NITRIC OXIDE, NOX Abstract The accurate analysis of nitrogen oxides at trace levels is of increasing importance in our society, due to its implications on photochemical smog. This has led to tighter regulations on emissions, and more stringent demands on the analytical performance of emissions monitoring systems. […]

PRESENTED AT: ISA Analysis Division, Houston, TX Keywords ULTRAVIOLET ABSORPTION SPECTROSCOPY, APPLICATIONS, SULFUR RECOVERY, SCOT CONTACTOR, NATURAL GAS, HYDROGEN SULFIDE Abstract Ultraviolet absorption spectroscopy has been used for decades in the refining and petrochemical industry. Online spectroscopic methods allow for rapid compositional analysis of process streams and provide the capability for real-time monitoring and control. […]

- Hamish Adam PRESENTED AT: Annual ISA Analysis Division Symposium, Framingham, MA Keywords Ultraviolet, Photometers, Absorption, Process Control Abstract Many different analytical techniques have made the transition from the laboratory to online process monitoring. UV photometry has made this transition more easily than most because it possesses some inherent advantages. Simple, robust optics and absence […]
