Test Results of Error Resilience With Modified Error Resilient Syntax With Data Partitioning and RVL

An ion exchange vessel which may be used as a condensate polisher for high pressure steam generating systems is disclosed. The vessel contains a mixed cation and anion ion exchange resin bed and it has a central collector and upper and lower distributors which increase the service flow rate through the ion exchanger. The distribution holes in the laterals and the weep holes in the central hub of the lower distributor are not screened, and resin is removed from the vessel through the unscreened distribution and weep holes. A screened off-center drain is provided to facilitate the draining of liquid from the vessel without the loss of resin.
