5 Differences Between Natural Gas and Propane

Dec 30, 2017 · Natural gas is mostly made up of methane, a greenhouse gas that's about 84 times more potent than carbon dioxide. Fortunately, natural gas also burns more cleanly than most other fossil fuels. Therefore, pollutants from natural gas can usually only get into the atmosphere after leaks in pipelines or accidents during drilling.

Carbon Dioxide Separation from Flue Gases: A Technological

CO 2 is the primary anthropogenic greenhouse gas, accounting for 77% of the human contribution to the greenhouse effect in recent decade (26 to 30 percent of all CO 2 emissions). Main anthropogenic emissions of CO 2 come from the combustion of fossil fuels. CO 2 concentration in flue gases depends on the fuel such as coal (12–15 mol-% CO 2) and natural gas (3-4 mol-% CO 2).

Internal combustion engine - Wikipedia

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.
