Previously natural gas was an unwanted product and was lost to the atmosphere. However, not a very significant source of energy, its 21% injection into energy supply cannot be overlooked. The result has been more focus on natural gas in the aim of diversifying available gas supply (SBC Energy Institute, 2014). Natural gas is formed because of anaerobic respiration of organic matter trapped for example in seas. The result is that the organic matter causes source rock to subside, and the organic matter is trapped in the mud like substance called kerogen.

The result is increased temperature and pressure that breaks down the kerogen into wet gas or oil depending on what type the kerogen was. With continued pressure and temperature, the wet gas becomes lighter until in the last stage of metagenesis; then the heat converts the kerogen into methane gas and hydrocarbons. They are then expelled through primary or secondary migration and if trapped by an impermeable layer that converts the hydrocarbons into bitumen (SBC Energy Institute, 2014). Natural gas may contain hydrocarbons that may have heavier components than methane and may be extracted through processing.

LPG is a subset of natural gas liquids NGLS that may be liquefied through pressurization. Natural gas compositions differ between fields. This means that in some fields, contaminants may account for a larger percentage of the natural gas, and this raises the production costs with a potential of reaching non-economic levels. For example, the presence of corrosive H2s may require the use of alloys (SBC Energy Institute, 2014). Being a gas with high-energy storage per unit volume, this makes handling of natural gas hard.

The result is the need for proper packaging mainly to increase its energy density to allow for safe transportation. Compression and liquefaction are the answer to this. Liquefaction results in greater energy density. The result of both is the high
