Propane and butane were discovered in 1912 by Dr. Walter Snelling, a U.S. scientist. He identified these gases in gasoline, and he found that cooling and pressuring these gases changed them to liquid. He also learned that the liquefied gases could be stored and transported in pressurized containers. read more
Hydrocarbon gas liquids are hydrocarbons that occur as gases at atmospheric pressure and as liquids under higher pressures. HGL can also be liquefied by cooling. The specific pressures and temperatures at which the gases liquefy vary by the type of HGL. read more
LPG (or LP Gas) is the acronym for Liquefied Petroleum Gas or Liquid Petroleum Gas. 2. LPG is a group of flammable hydrocarbon gases that are liquefied through pressurisation and commonly used as fuel. read more
Depending on who you talk to, the definition of “hydrocarbon liquid” may vary. Some educators may try to limit the label to crude oil, preferring to use more specific terms for liquid hydrocarbons transitioned from a gas state instead, including “condensate” and “natural gas liquids” (NGLs). read more
