What Is The Makeup Of Natural Gas
Propane vs. Natural Gas: What's the Difference?
Let's start with what you probably already know: natural gas is a fossil fuel in a gaseous state that travels through pipes to people's homes for use as a fuel for cooking, heating and water heating. Many people believe that propane is the aforementioned gas stored in tanks of various sizes instead of delivered by pipe, but that is not the case. Propane is in fact a unlike fuel from natural gas, though the two are closely related. And so what'southward the difference between these two fossil fuel cousins?
Chemical Makeup
Natural gas that is drilled out of the ground is really a mishmash of several gases. Methane is the biggest component of unrefined natural gas, and is the i gas left at the cease of the refining process. So when someone uses natural gas for cooking or heating in their home, they are essentially burning marsh gas with an odorant (added for safety, information technology makes gas leaks more than easily detectable) and a few other additives. Other components of unrefined natural gas include butane, ethane, and propane. That's right, propane is really a function of unrefined natural gas that is separated out during the refining process sold separately. Both refined natural gas and propane are hydrocarbons (nature-formed compounds made up of hydrogen and carbon). Propane's chemical formula is C3H8 and methyl hydride'southward is CH4.
Concrete States
Unrefined natural gas, as the name implies, exists cloak-and-dagger in a gaseous state. Information technology is extracted as a gas and refined as a gas, but tin can be stored every bit a gas or a liquid. By irresolute temperature and pressure, refined natural gas can be liquefied — into a substance called liquefied natural gas (LNG) — for storage. Similarly, propane is extracted from unrefined natural gas equally a gas, merely unlike refined natural gas (methyl hydride), it is nigh always stored and transported in its liquid state, as a substance chosen liquefied propane gas (LPG). This is why propane is usually sold in gallons (a measure of liquid volume) and natural gas is sold in cubic feet (a measure of gas book). LPG is stored in pressurized tanks, and the force per unit area within the tanks keeps the propane in its liquid land. Just as before long as the tank's valve is opened and the LPG moves out of the tank, it escapes the pressure and vaporizes into gas country. This formerly-liquid-now-gas form of propane is what fuels stoves, heaters, and other residential appliances.
Energy Content
Which packs more than power, natural gas or propane? The pretty articulate answer is propane. The energy content of nigh fuels is measured in British Thermal Units (BTUs), so comparing the BTU content of identical quantities of different fuels gives an accurate comparison of energy content. Although propane is transported and stored as a liquid, we'll refer to its gaseous state for the sake of a more direct comparison with natural gas. One cubic human foot (ft3) of natural gas contains 1,030 BTUs and i cubic foot of propane gas contains two,516 BTUs, giving propane about twice the energy content of natural gas. Propane101.com offers this comparison to put BTU values in the context of heating fuel:
• 100,000 BTU/hr furnace will employ about 97 cubic feet of natural gas (100,000 ÷ 1,030 = 97.1) in 1 hour
• 100,000 BTU/hr furnace will utilise nearly 40 cubic anxiety of propane (100,000 ÷ 2516 = 39.vii) in i 60 minutes
Then at that place you have it. Propane, by nature a component of natural gas, is separated out during the refining process to go a more powerful fuel. Now that you're educated, accept it on yourself to drop some noesis on the next person you hear refer to propane as natural gas or vice versa.
