Solved Examples

Steam Condensate available at 150 PSIG is to be flashed to a lower pressure of 15 PSIG. Condensate Flowrate is 10,000 lb/hr, Calculate amount of Vapor and Liquid generated on flashing.

Result
Vapor 1271.4 Lb/hr
Liquid 8728.6 Lb/hr

Estimate amount of 4.0 Kg/cm2G steam that can be generated by flashing 5000 Kg/hr of 10.5 Kg/cm2G steam condensate available at 180 °C temperature.

Result
Steam 261 Kg/hr
Liquid 4739 Kg/hr
