  • 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.
