Biogas is usually methane, not LPG. We can convert methane into CNG or LPG. LPG and natural gas are used in the same way, but also differ in many respects.
LPG and natural gas are widely available and used in thousands of applications in homes and businesses. There are also two major differences in the method of burning LPG (propane) and natural gas (methane).
biogas advantages and disadvantages
The first difference concerns the energy content
LPG has a giant calorific utility or energy content. The same amount of heat needs less gas to produce.
LPG needs more oxygen. The second difference is the oxygen-to-gas ratio required for proper combustion. It requires oxygen to gas ratio of about 25 to 1.
Natural gas needs a ratio of around 10 to 1. To achieve this difference, We supply LPG in a smaller quantity, but at a higher pressure, drawing more oxygen along with it to the combustion process.
LPG (liquefied petroleum gas)
The term LPG actually includes more than one type of gas. There are a number of hydrocarbon gases that belong to the LPG category.
It can press into a liquid at relatively low pressures with their common feature. The two most popular are propane and butane.
Other biogas advantages and disadvantages
In Australia, people buy LPG from Propane. LPG tankers supply LPG in gas cylinders to replace or refill on site. LPG has many names in Australia, including LPG, bottled gas, propane, grilling gas, camping gas, and LP gas. It’s the same gas. The propane chemical formula is C3H8.
Butane has certain specific applications in which it has an advantage over propane. These include greenhouse applications and use as a propellant in aerosols. The butane chemical formula is C4H10.
Autogas (the mixture of propane/butane)
Autogas sold at petrol stations can be simply propane or a mixture of propane/butane. The car is economical not only in the LPG car but also in Autogas, cleaner fuel is burned than gasoline, so the life of the engine is actually lengthened and the emission of greenhouse gases reduced.
Natural gas (methane)
Natural gas is primarily methane to make from biological waste. After extraction from the soil, it may also contain ethane, propane, butane, and pentane. The chemical formula for methane is CH4.
Natural gas or “gas network” is supplied gas to homes and enterprises by gas pipelines or “gas networks” (regulatory systems). In this way, most Australians receive gas.
CNG Methane gas can be stored under high pressure, usually over 200 bar, but it is not very economical when transporting over long distances. City buses are a good instance of a successful CNG application.
Methane is tasked into LNG by cooling it to -161 ° C, at which point it becomes a liquid. This reduces the volume of natural gas by a factor of over 600 times when it goes from gas to liquid.
It’s like going from the beach ball to ping-pong ball. This reduced volume facilitates economical to transport by sea or by road.
Typical LNG applications include industrial applications and long-distance transport. LNG-related technology is generally not profitable for small users, such as homes and small businesses.</p
