According to online sources, liquid hydrocarbons refer to hydrocarbon compounds with 5 to 16 carbon atoms (C5–C16) that are in a liquid state at normal temperature and pressure. Refers generally to hydrocarbons that are in a liquid state at normal temperature and pressure. The refining industry sometimes refers specifically to liquefied petroleum gas. It is gaseous at normal temperature and pressure, and only under conditions of increased pressure or reduced temperature does it turn into a liquid state; it is often referred to as liquid hydrocarbon during this process. It seems contradictory – what are liquid hydrocarbons usually in refineries?
The liquid hydrocarbons and liquefied gases in refineries refer to components mainly composed of C3 and C4.
We refer to liquefied gas as liquid hydrocarbons: lol
I think it might be a matter of the terminology used by different refineries; for example, our refinery never refers to liquid hydrocarbons as such, but instead calls them liquefied gas, gasoline, and diesel!
