When the liquefiable hydrocarbons are characterized as being hexane or higher molecular weight components, they are reported as GPM (C6+). [2] [3] However, the quality of raw produced natural gas is also often characterized by the term GPM meaning the gallons of liquefiable hydrocarbons contained in 1,000 cubic feet (28 m 3) of
Drip gas, so named because it can be drawn off the bottom of small chambers (called drips) sometimes installed in pipelines from gas wells, is another name for natural-gas condensate, a naturally occurring form of gasoline obtained as a byproduct of natural gas extraction. It is also known as "condensate", "natural gasoline", "casing head gas ...
Bcf – billion cubic feet (of natural gas) Bcf/d – billion cubic feet per day (of natural gas) Bcfe – billion cubic feet (of natural gas equivalent) BD – bursting disc; BDF – below derrick floor; BDL – bit data log; BDV – blowdown valve; BGL – borehole geometry log; BGL – below ground level (used as a datum for depths in a well)
Natural gas is consumed almost exclusively as fuel. Coal is used as a fuel and as a reducing agent in metallurgy . A small fraction of hydrocarbon found on earth, and all currently known hydrocarbon found on other planets and moons, is thought to be abiological .
There are a very large number of petrochemicals produced from the BTX aromatics. The following diagram shows the chains leading from the BTX components to some of the petrochemicals that can be produced from those components: [2] Diagram of the chain of petrochemicals derived from the BTX aromatics.
VPH is also known as petrol (or gasoline) range organics (PRO or GRO) and includes hydrocarbons from C6-C10. Diesel range organics (DRO) includes hydrocarbons from C10-C28. [2] Various methods to analyze the components of TPH are introduced in a Nordic report. [3]
Natural gasoline is a liquid hydrocarbon mixture condensed from natural gas, similar to common gasoline (petrol) derived from petroleum. The chemical composition of natural gasoline is mostly five- and six-carbon alkanes ( pentanes and hexanes ) with smaller amounts of alkanes with longer chains. [ 1 ]
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
