Propane is a non-toxic, colourless, and odourless gas, which is usually compressed and stored in liquid form. The biggest source of propane is natural gas processing. As mentioned above, it is a by-product of the processing.
Propane also can be a by-product of crude oil refinement. While the two gases have a lot of similarities e. There are a lot of similarities and differences between natural gas and propane. Both are odourless, colourless, and clean-burning fossil fuels.

LPG vs. Table of Contents. What is CNG Fuel? CNG vs. You can see how LPG is better than natural gas when you buy a cooktop. Cooktops usually come with two sets of gas jets. The ones for LPG have a much smaller hole and use less gas. LPG gas has some distinct advantages, including portability and higher energy content.
It may also be cheaper than natural gas in many situations. Natural gas has a safety advantage vs LPG. As natural gas is lighter than air, in the event of a leak, natural gas will dissipate more quickly. As LPG propane is heavier than air, it may collect in basements or near the floor of a home. Natural gas has some other advantages, too. So, as to if LPG is better than natural gas, it really comes down to a matter of opinion.
Both gases have their advantages. The calorific value of natural gas heating value of natural gas is The calorific value of LPG gas propane is So, LPG has a higher energy content than the calorific value of natural gas heating value of natural gas. With this higher calorific value, less LPG is required to produce the same amount of heat. The heating value of methane is Propane has a higher heating value — energy content — than the heating value of methane, with It would be difficult, if not impossible, to tell the difference between cooking with LPG-propane vs natural gas.
The difference between cooking with propane vs natural gas is an even draw. Propane vs natural gas methane vs propane cooking flame temperatures are almost identical, they both respond instantly to cooking temperature control changes and they both look the same. The cooking user would be unaware of the differences in gas to air ratio and propane vs natural gas supply pressure.
Comparing the cooking energy content of propane vs natural gas, natural gas is lower but it is typically less expensive so it tends to cancel out. It really comes down to the prices and tariffs of the two to determine which has a lower effective cost, after daily supply charges network access fee , other charges and the actual cost of the gas.
The autoignition temperature is the lowest temperature at which a substance spontaneously ignites in air, with no other ignition source.
So, based on their respective autoignition temperatures, propane is more flammable than methane because it spontaneously ignites at a lower temperature. The air to gas ratio for natural gas is around 10 to 1. The air to gas ratio for LPG gas is approximately 25 to 1. To achieve this difference, LPG is typically provided in a smaller quantity but at a higher pressure, drawing more oxygen with it into the combustion process, giving LPG a higher air to gas ratio than for natural gas.
The heavier relative density of LPG makes it settle in air. There is a density difference between LPG and the relative density of natural gas. LPG is more dense has a higher specific gravity than the relative density of natural gas. Density of natural gas is not heavier than air. Density of natural gas methane is lighter than air, as it is less dense lighter than air, with the relative density of natural gas being 0. Their common characteristic is that they can be compressed into liquid at relatively low pressures.
Natural Gas Liquids — NGLs — are heavier gaseous hydrocarbons that are included in the raw natural gas stream from the wellhead. NGLs include propane, butane, isobutane, ethane, ethene, propene, isobutene, butadiene, pentane, and pentene and pentanes plus. Pentanes Plus is a mixture of liquid hydrocarbons, mostly pentanes and heavier. Natural gasoline is the largest component of pentanes plus. Raw natural gas also contains impurities including water vapour, hydrogen sulphide H2S , carbon dioxide, helium, nitrogen, and other compounds that must be removed.
Propane is the gas that is supplied to virtually all homes and most businesses that purchase LPG in Australia. Butane is supplied to certain businesses that specify Butane, as opposed to Propane.
Butane has some specific applications where it has advantages over Propane. The determining factor of the percentage of propane and butane in LPG is primarily the availability of each where you are located. Not only is running an LPG car economical, but Autogas is also cleaner burning fuel than petrol, so engine life is actually extended and greenhouse gas emissions reduced. Natural gas is a fossil fuel hydrocarbon gas mixture found in underground rock formations. Raw natural gas composition is made of methane, propane, butane, isobutane, ethane, ethene, propene, isobutene, butadiene, pentane, pentene and pentanes plus.
Refined natural gas is primarily made of methane and is commonly used for cooking, heating, hot water, electrical generation and vehicle fuel. The natural gas liquids — NGLs — are part of the natural gas composition and are separated out for individual distribution.
Most of these are usually stripped out of the natural gas composition for other specific applications before it is passed along through the pipelines. Raw natural gas composition includes impurities that are also removed, including water and sulphur. There is actually a term for this. In industrial applications, it commonly heats boilers for various processes, as well as dryers, ovens and kilns. The generation of electricity is also a major use of natural gas, as it is much cleaner that coal fired generation.
Electricity generation can be via direct gas powered turbines, indirectly with steam turbines or a combination of the two, where the waste heat from the gas turbines is recycled to produce steam and drive steam turbines. Finally, the dry gas is passed through the gas pipelines that deliver it to our homes and businesses. As noted previously, raw natural gas may include propane, butane, isobutane, ethane, ethene, propene, isobutene, butadiene, pentane, and pentene and pentanes plus. Impurities such as water vapour, hydrogen sulphide H2S , carbon dioxide, helium and nitrogen are also found in raw natural gas and must be removed.
SNG can be used in place of natural gas, as it has virtually identical combustion characteristics. Images courtesy of TransTech. In comparison, LPG is delvered in gas bottles and by tanker truck.
