A TXRF System for Monitoring Mercury Emissions Phase II Award

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

During the Phase II project, nanoXRF will develop a commercial TXRF system for measuring mercury emissions from coal power plants. The commercial system will be  installed and tested in several coal power plants during this contract.

The need for this technology arose from the MATS which was written into the federal register by the EPA.

“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.”
