Decatherm | The unit of heat energy equivalent to one million British thermal units (BTU), or an MMBTU. |
Dew Point | The temperature at any given pressure at which liquid initially condenses from a gas or vapor.Ê It is specifically applied to the temperature at which water vapor starts to condense from a gas mixture (water dew point) or at which hydrocarbons start to condense (hydrocarbon dew point). |
Dkt | Abbreviation for Decatherm, equivalent to one MMBtu. |
Drip Gasoline | Hydrocarbon liquid that separates in a pipeline transporting gas from the well casing, lease separation, or other facilities and drains into equipment from which the liquid can be removed. |
Dry Btu | The heating value of a cubic foot of natural gas that does not contain a significant moisture (water) content. |
Dry Gas | Natural gas that either (1) does not contain a significant moisture (water) content, or (2) does not contain significant amounts of liquefiable hydrocarbons.Ê Gas in this second definition preferably should be called lean gas. |
