Cooling Tower for the Supercritical Steam Plant (Updated 5

1) Determine the volumetric flow rate of the cooling water through the condenser. You may neglect the power required to drive the circulating pump. Draw the cooling tower process between stations (12) - (13) on the Psychrometric Chart. Notice that we have extended the moisture specific humidity range on this chart from 30 to 35 grams/kg-air in order to accomodate the extremely high humidity at station (13),

Chemistry and Corrosion Issues in Supercritical Water

cooling process, which does not require steam generators, allows to achieve higher thermal efficiency (up to 44-48%) as compared to top performing in this aspect existing NPPs (less that 33%). Supercritical water (with pressure above 22.12 MPa and temperature above 374.3 ºC) is a single flow fluid, which is very temperature dependent.
