Pall Introduces Systems for Environmental and Emissions Monitoring
Xact* systems monitor single or multiple metals in on-stack and ambient applications such as incinerators, coal-fired power plants, smelters, cement kilns, and air quality monitoring units. The systems generate precise data that will enable power producers and other industries to demonstrate compliance with, or take measures to meet, regulatory requirements.
Developed in partnership with Cooper Environmental Services (CES) LLC, a leading supplier of continuous metals monitors (CMMs), the Xact technology takes advantage of XRF to identify heavy metals trapped in Pall’s microporous filtration membranes. When exposed to X-rays, the membrane surfaces exhibit fluorescent signatures that identify the nature and volume of the heavy metal residue captured within.
"Xact systems are the latest example of Pall's commitment to broadening its portfolio of environmental protection solutions," said Greg Collins, senior vice president, Pall Energy & Water. "By combining our microporous membrane media with CES’s market-proven XRF technology, we are now able to offer our customers complete systems for single or multi-metal emissions monitoring."
For emissions monitoring at the stack, Pall is now offering the Xact 640 Multi-Metal Continuous Emissions Monitoring System and the Xact 645 Continuous Mercury Monitor. For ambient atmospheric testing, Pall offers the Xact 620 Ambient Metals Monitor, which can be used to identify “hot spots” in complex urban air sheds, and the Xact 625 Multi-Metals Fence-Line Monitor designed for monitoring ambient air at the facility periphery.
Environmental and emissions monitoring is of special significance to the power generation industry, which will need to comply with forthcoming utility mercury reduction (Utility MACT) rules promulgated under the U.S. Clean Air Act. Xact systems enable the owners and operators of coal- and oil-fired electric utility steam generating units to collect data that will enable the EPA to assess emissions from these facilities.
