Discussion on deoxidation using thermal deoxidizers
Thread Content
As title suggests: 1. What are the necessary conditions for deoxygenation? 2. Must steam be used for heating and deoxygenating the incoming water? If the temperature reaches a level at which deoxygenation is possible, can we do without steam?
1. A necessary condition for deoxygenation is to raise the water temperature to a certain level so that the oxygen dissolved in the water can escape. It is usually necessary to raise the water temperature to near boiling point. 2. Steam is not necessarily required for heating and deoxygenating the incoming water; it is sufficient to reach a temperature high enough to release dissolved oxygen. Theoretically, steam can also be avoided if the required temperature can be achieved through other heating methods. However, steam is used because of its high thermal efficiency and fast heating speed. .
1. The principle of thermal deoxidation is Henry’s law; for more details, you can refer to the principles of deoxidizers； 2. Generally, the setting conditions for thermal deaeration are 105 degrees and a pressure of 20–30 KPa ； In some cases, this requirement cannot be met, and adjustments must be made based on the conditions on site until the deoxidation parameters of the deoxidizer satisfy the design requirement of less than 40 ppb.
