Present-Day Feed-Water Treatment for High-Pressure Boilers

The paper is concerned with industrial boiler plant generating steam for power and process at pressures of 1000–2000 lb/in 2 and having a high make-up of treated feed water. The capital and running costs of the water treatment plant and process are therefore much more important than in power station boilers where make-up is small.

such systems. The volatility of DEHA increases from 100 psig to 300 psig and then falls gradually at increasing pressures. DEHA, therefore, behaves in a similar manner as neutralizing amines. It would, therefore, be expected that volatility at high pressure will still be for giving residuals in steam.
