Beneficiation Of High Sodium Fly Ash

“Beneficiation of High Sodium Fly Ash,” reviews drivers for sodium dry sorbent injection, impacts of sodium in fly ash disposal, options for stabilization, and test results. This is a timely topic, given the new EPA ruling issued December 19, 2014 which regulates coal combustion residuals (CCRs) from coal power plants, and clarifies technical requirements for coal ash landfills and surface impoundments nationwide under Subtitle D of the Resource Conservation and Recovery Act (RCRA), the nation’s primary law for regulating solid waste.
