2.1.1 Oil
It refers to crude oil, petroleum products (gasoline, kerosene, diesel oil and naphtha, etc.), stabilized light hydrocarbon and stabilized condensate.
2.1.2 Crude oil
It refers to the liquid compound produced from the oil well, giving priority to hydrocarbon.
2.1.3 Natural gas liquid (NGL)
It's the generic term of liquid hydrocarbon compounds recovered from the natural gas but not passed through stabilizing treatment, generally including ethane, liquefied petroleum gas (LPG) and stabilized light hydrocarbon. It's also named as mixed light hydrocarbon.
2.1.4 Liquefied petroleum gas (LPG)
It's in the gaseous state under normal temperature and pressure but becomes liquid after compression or cooling. It's mainly consisted of propane, butane and their compounds.
2.1.5 Stabilized light hydrocarbon
It's abstracted from natural gas liquid (NGL) and is mainly consisted of pentane and other heavier hydrocarbon, the end boiling point shall not be higher than 190℃, under the specified vapor pressure, it allows including a little butane. It's also named as natural gasoline.
2.1.6 Gas condensate
It refers to the hydrocarbon liquid abstracted from the condensate gas but not stabilized.
2.1.7 Stabilized gas condensate
It's abstracted from the gas condensate and is mainly consisted of pentane and the other heavier hydrocarbon. |
