Fast, simultaneous and continuous monitoring of NOx and NH3 in DeNOx applications

In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3. For preparing ...

Tri-NOx Multi-Chem Wet Scrubber. Case Study of Our NOx Scrubber in a Plastics Resin Plant.

As part of a commitment to reduce airborne emissions – or even the threat of such emissions – the Mt. Vernon, IN plant of GE Plastics has installed a NOx scrubber. When such GE Plastics products as Ultem resins are produced, nitric acid is used, and emissions from this step are tightly controlled. But to address upset conditions, the company opted to install an emergency scrubber that can treat ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
