The Flexibility & Versatility of a Portable Emissions Analyzer

Issue Fixed CEMS (Continuous Emissions Monitors) Measure at One Location CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces. If the CEM ...

State of Oregon acquires CEREX micro hound multi-gas analyzers for hazmat first responders

Abstract: "During the overhaul phase of a structure fire, firefighters commonly doff their self contained breathing apparatus SCBA protection for easier working conditions and traditionally rely upon carbon monoxide (CO) detection as the determinate for this action. A CO level of below 35 ppm has traditionally been the acceptable limit for firefighters to wear this lesser level of ...

NH3 Slip Monitoring in Fluidized-bed Catalytic Cracking Using the LDS 6 Gas Analyzer – Case Study

Fluidized catalytic cracking (FCC) units are used in refineries to convert low value heavy oils into more valuable lighter compounds. Cracking units are sources of emissions of pollutants (e.g. NOx) and must comply with concentration permits set by local or federal authorithies. Modern technologies are applied to reduce the content of pollutants and to monitor certain gas compounds (here: NH3) in ...
