Feed Water Deaeratores
Packaged Deaerator systems, 5,000 to 200,000 PPH. Conditions feedwater to 0% CO2 and .005cc/liter of oxygen.
imageThe HURST "OXY-MISER" deaerating boiler feedwater system eliminates the need of expensive oxygen scavenger chemicals and also offers the following advantages:
* Removes carbon dioxide as well as oxygen.
* Raises the boiler feedwater temperature, eliminating thermal shock in boilers.
* Improves overall boiler room efficiency.
* Feedwater pumps are sized for each individual application - assuring total compatibility and optimum operation.
* Vessels are ASME Code constructed for 50 psig.
* Compact design means smaller boiler room requirements.

Dissolved gases such as oxygen and carbon dioxide must be reduced in Boiler Feed Water in order to prevent boilers and steam circuits from corrosion. The thermo-physical deaeration process is by far the most applied technology when a reduction of oxygen to only a few parts per billion is required. While part of the BONO Group, ARTES Ingegneria is in the business of Deaerators since 1958.
The degassing process is achieved in the deaerating tower where make-up water is atomised on a set of special packing that increases the contact surface between water and steam. Oxygen and carbon dioxide are stripped by the steam flow and vented through a calibrated orifice. Deaerated water is collected in the storage tank so as to assure an adequate “Hold-up” time for the boiler downstream.
According to the design capacity and steam flow, the deaerating tower may be arranged on a vertical or horizontal geometry so that, in the latter case, a larger surface of mass and heat transfer is implemented.
Deaerators are manufactured and marketed on BONO Artes’ own proprietary design in order to assure the complete responsibility of the concerned unit.

The Deoxygenation system for injection water, can be delivered in two different versions; Minox DeOx System - 2 Stages, or Minox Deox System - Compact Tower.
The MinoxTM DeOx System - 2 stages :
This is the ultimate Deoxygenation system configuration available in the market today. It gives extremely small and light units and requires a minimum of maintenance and utilities.
The MinoxTM Deox System - Compact Tower:
By utilizing the MinoxTM process in conjunction with a tower and packing, the same technical features as the 2-stage system are achieved. It will however require more space and support than the 2-stage system, but still significant less than a conventional system. This means that overall, for most new installations, the 2-stage system will be more cost effective.

Seawater Deaerators
Edwards is a market leader in the manufacture of deaeration equipment. We offer a complete range of deaerators including seawater deaeration packages for use in water injection systems. These designs include conventional packed column vacuum deaerators and the unique Edwards patented spray packed vacuum deaerator, which uses the patented spray distributor technology in conjunction with high mass transfer efficiency packed beds. We can also provide inlet gas stripping, steam stripping and trace gas assisted deaerators.

The process is based on the patented and well-proven MinoxTM process. The process has been in use for offshore applications since 1991 and has now been introduced to the conventional industry with low capacity units.
The MinoxTM process gives small, compact and economical systems, also for this application. The most common industrial application for the conventional industry is Deoxygenation of water in cooling circuits, district heat plants etc.
