In the deaerator, water is heated up to close to saturation temperature with a minimum pressure drop and minimum vent. Deaeration is done by spraying the feedwater to provide a large surface area, and may involve flow over multiple layers of trays. This scrubbing (or stripping) steam is fed to the bottom of the deaeration section of the deaerator.
