| description | Ion-exchange resins used in ultrapure water
processing are known to lose effectiveness with fouling. Mass-
transfer coefficient (MTC) is one property that defines
acceptable resin performance. MTC is measured by a simple
column test with known feed concentration of ions at sufficient
flow to achieve kinetic leakage out of bed. MTC deviation due
to exposure to film-forming amines (FFAs), as well as impacts
of resin storage time, are investigated. A filming amine (FA),
octadecylamine (ODA), was evaluated experimentally for
potential impacts on condensate polisher ion-exchange bead
resins (Dowex MS 650C (H) and Dowex MS 550A (OH)).
Results indicate significant reductions in MTC on both
cationic and anionic resin. In addition, unused resin stored for excessive times, up to 16 years, showed MTC reduction. |
