LPG, or liquid petroleum gas, is either propane or butane. It is a product of the refining process of crude oil. It can be stored by maintaining the liquid under pressure, about 100 psig. Natural gas is a fossil fuel that is gathered mainly by drilling, similar to drilling for oil. Once natural gas is collected it can be processed and cooled to
LNG is natural gas converted to liquid through liquefaction, while LPG is a liquefied gas and a byproduct of refining crude oil. LPG weighs two times what air does and is a colorless, odorless, and highly flammable gas, while LNG is a compressed natural gas that is 600 times smaller than the volume of natural gas.
Oil and natural gas are two distinct fossil fuels that have some key differences. Here are some of the main differences between oil and natural gas: Chemical composition: Oil is composed of hydrocarbon molecules of varying sizes and complexities, while natural gas is primarily made up of methane, with smaller amounts of other gases.
Cost effective NH3 has historically been priced competitively with gasoline and petroleum on an energy content (i.e., $/MM BTU basis). NH3 is currently produced from natural gas and coal. Current (April 2010) U.S. prices for coal, natural gas, and gasoline are $1.20, $3.97, and $20.00 per million BTU respectively.
Moreover, global gas markets are shifting towards liquefied natural gas (LNG) owing to the development of shale gas reserves in the US, the energy security issue of NG supply in Europe, and the increase in its international trade, which leads to an upsurge in global LNG demands from 360 million tons in 2020 to 700 million tons by 2040 [5]. The
Natural gas is a hydrocarbon mixture consisting primarily of saturated light paraffins such as methane and ethane, both of which are gaseous under atmospheric conditions. The mixture also may contain other hydrocarbons, such as propane, butane, pentane, and hexane. In natural gas reservoirs even the heavier hydrocarbons occur for the most part
