Coal fired power plant water chemistry issues: Amine selection at supercritical conditions and sodium leaching from ion exchange mixed beds
(2012-05)
Scope and Method of Study: This study evaluated thermal degradation kinetics of neutralizing amines in steam cycle coal fired power plants operating supercritical conditions as functions of temperature and pressure. The ...
Separation of Resin Types in Mixed Bed Ion Exchange Columns
(Oklahoma State University, 2011-05-01)
Resin separation is a vital step prior to regeneration of Ion Exchange resins. The degree of separation determines the extent of sodium and sulfate or chloride into the system from caustic and acid regenerants, respectively. ...
Impact of Filming Amine on Ion Exchange Resin for Ultrapure Water Application
(Oklahoma State University, 2013-12-01)
Two types of proprietary filming amines were tested in laboratory experimentation to evaluate potential impacts on condensate polisher ion exchange resins (Dowex 650C and 550A). The properties of filming amines to coat ...
