LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3), which means that LPG cannot simply be substituted for ...
Propane's per-BTU production of CO 2 is almost as low as that of natural gas. [28] Propane burns hotter than home heating oil or diesel fuel because of the very high hydrogen content. The presence of C–C bonds , plus the multiple bonds of propylene and butylene , produce organic exhausts besides carbon dioxide and water vapor during typical ...
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
Natural gas may be combined with hydrogen to form a mixture known as HCNG. Additional fuel gases obtained from natural gas or petroleum: Propane; Butane; Regasified liquefied petroleum gas; The composition of natural gas varies widely, but the table shows a typical composition. [4]
5.2 Differences between LNG and ... with an octane rating of 112 RON/105 AKI for propane and 120 ... (LPG), and 3,176 vehicles running on liquefied natural gas ...
The difference between HHV and LHV definitions causes endless confusion when quoters do not bother to state the convention being used. [10] since there is typically a 10% difference between the two methods for a power plant burning natural gas.
Liquefied natural gas is natural gas that has been liquefied for the purpose of storage or transport. Since transportation of natural gas requires a large network of pipeline that crosses through various terrains and oceans, a huge investment and long term planning are required. Before transport, natural gas is liquefied by pressurization.
[34] [35] [36] Audi has constructed a carbon neutral liquefied natural gas (LNG) plant in Werlte, Germany. [37] The plant is intended to produce transportation fuel to offset LNG used in their A3 Sportback g-tron automobiles, and can keep 2,800 metric tons of CO 2 out of the environment per year at its initial capacity.
