Combined makeup and sidestream softening field for a proposed closed-cycle cooling-system design. Final report. [Treated cooling water]
This report presents the results of a special pilot-scale field test conducted at Comanche Generating Station in Pueblo, Colorado. The objective of this test was to evaluate a proposed closed-cycle cooling system design which incorporated combined makeup and sidestream softening for scale control at high cycles of concentration. Public Service Company of Colorado, which cofunded the field test, needed to evaluate the proposed design for the planned Southeast Generating Station. The test used a portable skid-mounted field test unit (FTU) which was designed and fabricated under EPRI RP1261-1. Based on proposed design conditions, the FTU was operated for three weeks to obtain steady-state system chemistry data. These data were then compared with design estimates. The FTU combined softening system produced a treated water chemistry better than anticipated and the FTU operated at design conditions (20 cycles of concentration) without condenser scaling. The FTU results were also compared with estimates based on computer model simulations (CS-2276). Comparisons of the recirculating water compositions were in close agreement on the softener treated water compositions were attributed to inaccurate chemical feed rate data used as input to the computer models.
