Experiences Using Neutralizing Amines to Control pH
Steam-generating equipment that operates below design pressure can increase the potential for FAC to occur. This is because the specific volume of steam/water mixtures increases as pressure is reduced, resulting in higher velocities throughout the equipment. There was no impact on IP or HP boiler water pH due to the increased feed of MPA.
