SF6-alternative gases dew point units

What is Dew Point Corrosion? Dew point corrosion refers to corrosion resulting from condensation of acid gases such as sulfur dioxide, sulfur trioxide, hydrogen chloride, and others within the combustion products. At temperatures below dew points, these gases and the water vapor in the flue gas will condense to form sulfurous acid, sulfuric acid and hydrochloric acid which can lead to severe ...

  • Hydrocarbon dew point - Wikipedia

    The hydrocarbon dew point is the temperature (at a given pressure) at which the hydrocarbon components of any hydrocarbon-rich gas mixture, such as natural gas, will start to condense out of the gaseous phase. It is often also referred to as the HDP or the HCDP.The maximum temperature at which such condensation takes place is called the cricondentherm.
