retrograde condensation

This is the opposite of condensation: the so-called retrograde condensation.

Retrograde condensation occurs when gas in a tube is compressed beyond the point of condensation with the effect that the liquid evaporates again.

Recycling plants such as those at Kaybob, West Whitecourt and Crossfield produced liquids-rich gas from "retrograde condensation" reservoirs.

Below the dew point pressure, retrograde condensation occurs leading to the segregation and then the mobilisation of the condensate phase (above the critical condensate saturation) towards the producing wells.

Natural gas condensates (petroleum); Low boiling point naphtha — unspecified (A complex combination of hydrocarbons separated as a liquid from natural gas in a surface separator by retrograde condensation.

He discovered retrograde condensation and published his findings in April 1892 with the title "Metingen betreffende het oppervlak van Van der Waals voor mengsels van koolzuur en chloormethyl".

Because natural gas is not a pure product, as the reservoir pressure drops when non-associated gas is extracted from a field under supercritical (pressure/temperature) conditions, the higher molecular weight components may partially condense upon isothermic depressurizing-an effect called retrograde condensation.
