Feedstock: conventional and bio-based LNG

Aida Gonzalez Palomino

Conventional LNG

Liquefied natural gas (LNG) is a liquid hydrocarbon mixture with methane (CH4) as the main component.

Composition of LNG

Component name	Chemical formula	Composition (molar percentage)	Average composition* (molar percentage)
Methane	CH4	84% to 99%	90.4%
Ethane	C2H6	0.1% to 14%	6.4%
Propane	C3H8	0% to 4%	1.8%
Butane	C4H10	0% to 2.5%	0.9%
Nitrogen	N	0% to 1.8%	0.5%
Other		< 1%	0%

*Average composed from various worldwide source compositions

Bio-based LNG

Agriculture and waste (such as human sewage, fishery, municipal solid waste or paper mill slurry) are the two largest potential feedstocks for biomethane production, which is the basis of bio-LNG.
