Deaeration happens by spraying water and making it fall in a contact section. At the same time, steam acts as a stripping and heating medium in counterflow.

Cannon Artes has proprietary thermophysical deaerator technology called ZeroGas. Different deaerators can fall under the ZeroGas Deaeration technology.

In the Spray & Tray configuration, the degassing process is achieved in the deaerating tower, where make-up water is atomized on a set of special “structured packing.” This increases the contact between water and steam, where dissolved gases are stripped and vented with steam.

According to the design capacity and steam flow, the deaerating tower may be arranged vertically or horizontally to implement a larger mass and heat transfer surface.

We can provide “spray-type” deaerators that combine the deaerating and storage sections into one single tank with a very efficient design, leading to a more compact size and reduced weight.

We can partner with you for Integral Deaerators that can be installed directly on the LP drum of the heat recovery steam generator, with the advantages of using the steam produced within the drum itself and saving an additional storage section. This is a critical application since the steam flow within the deaerating tower is driven by the pressure loss across the mass transfer section (and by the differential temperature since the system is in liquid-vapor equilibrium).

Whatever is your need for deaeration, Cannon Artes’ expertise is at your fingertips.
