The Model SSL
deaerator is
fully customizable
and can be ordered
as a tank only or
complete skid
mounted assembly.
The Lockwood Model SSL deaerator is a low profile spray scrubber deaerator. The vessel includes a deaerating section that is integral to the horizontal storage section.
Lockwood Model SSL deaerators are designed to reduce the dissolved oxygen content of the feedwater to no more than 0.005 cc/liter (7 ppb) and reduce the titratable free carbon dioxide to zero. To do this, the feedwater goes through a two-stage mechanical deaeration process.
The incoming water is injected into a steam atmosphere in the top of the deaerator via stainless steel spray nozzles. The nozzles create a hollow conical spray pattern which results in a large surface area allowing rapid heating of the water.
As the water approaches saturation temperature, the dissolved gases are released by the water and carried away by the steam.
A majority of the corrosive gases are removed before the water strikes any steel surfaces within the deaerator. The non-condensable gases are then vented from the deaerator through a stainless steel vent pipe located near the top of the vessel. A valve and orifice are used to control the vent rate.
The hot deaerated water then passes through steam scrubber section of the deaerator. High velocity steam is forced through the water causing vigorous scrubbing of the remaining dissolved gasses.
