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 and the pressure at which such condensation takes place is called the cricondentherm.^[1] The hydrocarbon dew point is a function of the gas composition as well as the pressure.

Oil refineries are key to obtaining hydrocarbons; crude oil is processed through several stages to form desirable hydrocarbons, used in fuel and other commercial products. ... Natural gas is a gaseous fossil fuel consisting primarily of methane but including significant quantities of ethane, butane, propane, carbon dioxide, nitrogen, helium and hydrogen sulfide. ... In the physical sciences, a phase is a set of states of a macroscopic physical system that have relatively uniform chemical composition and physical properties (i. ...

The hydrocarbon dew point is universally used in the natural gas industry as an important quality parameter, stipulated in contractual specifications and enforced throughout the natural gas supply train, from producers through processing, transmission and distribution companies to final end users. A natural gas processing plant Natural gas processing plants are used to purify the raw natural gas extracted from underground gas fields and brought up to the surface by gas wells. ...

The hydrocarbon dew point of a gas is not to be confused with the water dewpoint which is the temperature (at a given pressure) at which water vapor present in a gas mixture will condense out of the gas.

The hydrocarbon dew point is related to the term GPM, understood as the number of gallons that condense out of 1000 cubic feet of gas, this GPM is reported as GPM(C2+) when the stream is characterized from ethane and GPM (3+) from propane.
