Have no fear, Scroothchy sends his regards! Some additional research on your part may be needed. Like the "fizz" in your sodapop [CO2], a constituent of atmospheric "air",.....propane [C3H8] is a constituent of natural gas [CH4]. To distribute LPG as LGOV does, a source of natural gas (most easily transported in a liquified state = LNG), and its processors, is of primary interest. Extraction of Propane, which is then liquified to LPG for ease of storage and transportation, is most readily obtained from Natural Gas in it's liquid or gaseous state. From associated technical publications: *************** Propane (C3H8)is a colourless, odorless, easily liquefied, gaseous hydrocarbon (compound of carbon and hydrogen),the third member of the paraffin series following methane and ethane. It is seperated from light crude oil, natural gas, and is a by-product of petroleum refining. Propane is commercially available as liquefied propane or as a major constituent of liquefied petroleum gas (LPG). Although a gas at atmospheric pressure, propane has a boiling point of -42.1 C (-43.8 F) and thus is liquefied under elevated pressures. It therefore is transported and handled as a liquid in cylinders and tanks. In this form, alone or mixed with liquid butane, it has great importance as a fuel for domestic and industrial/commercial uses and for internal-combustion engines. *************** Chemical Sciences Inorganic Chemistry Inorganic Industrial Chemistry The Fuel Industry: Natural Gas and Petroleum Natural Gas Subterranean rock formations, particularly those of dome shape, are often found to contain natural gas; the domes are tapped by drilling. Natural gas and oil (petroleum) are often found in the same or adjacent areas. Significant producing areas are in the Persian Gulf area, the Gulf Coast areas of the United States, southwestern Soviet Union, Rumania, Indonesia, the North Sea and western Canada. Natural gas is usually over 80% CH4, with decreasing quantities of ethane, propane, and butane, and may contain nitrogen in varying proportions. The higher hydrocarbons are more valuable as raw materials for industry than as a fuel and therefore are often stripped from the gas stream by plants built astride the pipelines. A significant impurity in some natural gas sources is H2S. Such "sour" gas must be purified by removal of the H2S before sale since SO2 would be formed on combustion. Sulfur removal is generally achieved by use of some variant of the Claus process in which the hydrogen sulfide is partially oxidized. The hydrogen sulfide is absorbed from the natural gas at ambient temperature in a scrubber, either in alkanolamine-glycol solution: ************** My field of practice is facility power distribution and utilization, factory automation, and controls and instrumentation systems; so, my process engineering and chemistry skills are perhaps a little weak. It stands to reason, however, that if MAJOR PLAYERS in the petro market are making great efforts to extend LNG lines from Alaska towards the Asian continent - a considerable market and large profits are driving those issues. If they make the supply more plentiful and less expensive, LGOV benefits; since the "gas" (be it LNG or LPG) is not getting into the country unless it moves through LGOV's pipelines, tanks, and cylinders.
