Question

what is the weight and percentages of different gases in lpg cylinders ​

Answer 1

Answer:

LPG – Liquefied Petroleum Gas – (Autogas) is primarily comprised of propane, butane, and isobutane in a range of mixtures. It is produced as a co-product of crude oil refining and natural gas processing. The constituents of LPG are gaseous at 20°C and 1 atmosphere pressure (NTP).

LPG - Liquefied petroleum gas or liquid petroleum gas, also denoted as just propane or butane, are both flammable hydrocarbon gases used as fuel for LPG heating gases, cooking and vehicular fuel.

LPG is both propane and butane. As butane does not vaporise (turn from liquid to gas) well at colder temperature, LPG suppliers typically add propane to the percentage of propane and butane in LPG. Propane has a lower boiling point, at -42° vs -0.4°C for butane. So, propane will continue to vaporise in colder climates.

Energy Content: Propane vs Butane vs Natural Gas

Compared in gaseous volume, butane does have a higher energy content at 111.4MJ/m³ vs propane at 93.2MJ/m³. Natural gas is only 38.7MJ/m³.

Liquefied petroleum gas (LPG or LP gas) is also referred to by its constituent names - propane or butane. LPG are hydrocarbon fuel gases used for heating, cooking, hot water and vehicles.

Most countries have either 100% propane (Australia & USA), an LPG gas mixture of 60:40 propane:butane (NZ & Belgium) or percentage of propane and butane in LPG around 35:65 propane:butane LPG gas mixture (India, Spain & Hungary).

Answer 2

Answer:

LPG is composed hydrocarbons containing three or four carbon atoms. The normal components of LPG thus, are propane (C3H8) and butane (C4H10). Small concentrations of other hydrocarbons may also be present. LPG burns readily in air and has an energy content similar to petrol and twice the heat energy of natural gas.
