A TXRF System for Mercury Emissions Monitoring

In the FY 2013 Phase I Release I the U.S. Department of Energy released topic 13, “Advanced Fossil Energy Separations and Analysis Research”, subsection c, Power Plant Mercury Emissions Monitoring as follows:

“In December 2011, the Environmental Protection Agency (EPA) announced the Mercury and Air Toxics Standards (MATS) for power plants. This rule requires existing and new coal-fired power plants to meet stringent mercury reduction levels. Specifically, the rule applies to new and existing electric generating units (EGUs) that burn coal or oil to generate greater than 25 megawatts (MW) of electricity for sale and distribution through the national electric grid to the public. These new standards limit mercury emissions on the order of tenths to ten-thousandths of a pound/gigawatt-hour of gross electrical output (lb/GWh) depending upon the coal type, whether the plant is existing or new, and the power plant technology.”

UHV Technologies, Inc., the parent of nanoXRF was awarded the Phase I contract with the proposal for a TXRF System for Mercury Emissions Monitoring. UHV Technologies, Inc. proposes an innovative approach to measure mercury concentrations that utilize the known methods of Total Reflection X-Ray Fluorescence (TXRF) as an improvement to the instrument made using an Energy Dispersive X-Ray Fluorescence (ED-XRF) instrument.

During the Phase I project, nanoXRF will develop novel mercury sensing substrates that can measure ng/cm2 specifically designed for use by commercial TXRF systems. This substrate will allow for the detection of mercury within the MATS and current EPA regulations.
