DIODE ARRAY PROCESS ANALYZER - FOR SULFUR RECOVERY APPLICATIONS

摘要

Legislation enforcing emission control of toxic substances has now been passed worldwide.3 An important subgroup of such substances is comprised of the sulfur-based compounds; sulfur recovery units are a critical component of the processes of oil refining and liquefying natural gas. Fast, accurate, and continuous analytical techniques are necessary to comply with these regulations, and to improve efficiency in sulfur recovery processes. A variety of recovery processes are normally operated at a single plant; using a single type of analyzer for a majority of applications guarantees better technical support and a higher level of expertise in plant operators. This paper reviews the utilization of spectroscopy in step with diode arrays, a time-tested, industryaccepted technology for sulfur recovery applications. One analyzer with different sampling systems can be used for a variety of applications. Common applications include Hydrogen sulfide (H2S), Tail Gas, Natural Gas and Mercaptans.
