COURSE DESCRIPTION:

 

Deaeration is primarily the mechanical removal of dissolved gases from a fluid, in this case, water. There are many industrial processes that require gas-free water. Deaerators are commonly used in steam plants to heat boiler feedwater sufficiently to expel dissolved gases such as oxygen and dissolved carbon dioxide.  Deaerators have a very significant impact on the operating costs of every steam plant – they are often large users of steam and their poor performance may also raise the risk of a far more insidious plant-wide problem – corrosion. Boiler feedwater normally contains two harmful dissolved gases – oxygen and carbon dioxide. The purpose of deaeration is to remove these gases before they are liberated in the boiler. This reduces corrosion in the pre-boiler, boiler, steam lines, condensate lines, and heat transfer equipment.

The best performance guarantee from a deaerator manufacturer is 0.005 cc/L of oxygen. Residual oxygen in the water from mechanical deaeration is subsequently removed by chemical deaeration, that is through the use of a chemical oxygen scavenger. When mechanical deaeration is not available, chemical deaeration may sometimes be adequate by itself, but for the large majority of systems, a combination of deaeration methods is employed.

This 3-hour webinar covers many key design and operational aspects of both mechanical and chemical deaeration. The focus is on the optimization and troubleshooting of mechanical thermal deaerators as well as the proper application of a myriad of reducing agents (oxygen scavengers), including sulfite salts and volatile organic products.  This course also addresses many other topics such as monitoring techniques, the safety-related problem of deaerator cracking and the selection of the optimum chemical oxygen scavenger product.
