LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3 ) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3 ), which means that LPG cannot simply be substituted for ...
A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or non-flued, or vented and unvented .
Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane. [1] Autogas is widely used as a "green" fuel, as its use reduces CO 2 exhaust emissions by around 15% compared to petrol. [2]
The LPG used as auto fuel and cooking gas in Asia and Australia also has very high butane content. Propylene (also called propene) can be a contaminant of commercial propane. Propane containing too much propene is not suited for most vehicle fuels. HD-5 is a specification that establishes a maximum concentration of 5% propene in propane.
It may also be used gas heaters, camping stoves, and even to power vehicles, as they have a high calorific value. Fuel gas is widely used by industrial, commercial and domestic users. Industry uses fuel gas for heating furnaces, kilns, boilers and ovens and for space heating and drying .
A gas stove is a stove that is fuelled by flammable gas such as natural gas, propane, butane, liquefied petroleum gas or syngas. Before the advent of gas, cooking stoves relied on solid fuels, such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836.
The higher the octane rating, the more resistant the fuel is to autoignition under high pressures, which allows for a higher compression ratio. Engines with a higher compression ratio, commonly used in race cars and high-performance regular-production automobiles, can produce more power; however, such engines require a higher octane fuel.
In general, gas condensate has a specific gravity ranging from 0.5 to 0.8, and is composed of hydrocarbons such as propane, butane, pentane, and hexane. Natural gas compounds with more than two carbon atoms exist as liquids at ambient temperatures and pressures. [4] Propane, butane, and isobutane are
