Brief Introduction to Propane

Propane is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Propane is one of a group of liquefied petroleum gases (LP gases). The others include propylene, butane, butylene, butadiene, isobutylene, and mixtures thereof. Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal.

Chemical Reactions of Propane

Like other alkanes, Propane also undergoes combustion reactions in a similar manner. Propane burns in the presence of an excess amount of oxygen to produce carbon dioxide and water.
C3H8 + 5O2 → 3CO2 + 4H2O + heat
When too much or too less oxygen is available for the combustion reaction, incomplete combustion takes place, forming soot (carbon) and/or carbon monoxide.
2C3H8 + 9O2 → 4CO2 + 2CO + 8H2O + heat
C3H8 + 2O2 → 3C + 4H2O + heat
The hydrogen content of Propyl hydride is extremely high and therefore burns hotter when compared to diesel fuel or home heating oil. The presence of C–C bonds causes it to burn with a flame.

Propane safety and handling

Handle Propane Tanks Carefully

Don’t use or store portable propane tanks in basements or living spaces.
Properly secure portable propane tanks when transporting.
Do not leave portable propane tanks in cars or closed vehicles.
Secure temporary tanks when used for building heat, hot water, or cooking.
Contact a qualified propane service retailer to connect tanks to appliances.

Use Propane Gas Appliances With Care

Do not use propane gas BBQ grills inside.
Refrain from using propane stoves or ovens for space heating.
Do not use portable electric generators indoors-keep outside of building.
Have a qualified propane service technician connect appliances and perform a leak test

What to Do If You Smell Gas

Immediately extinguish all smoking materials and open flames.
Get everyone out of the area where you suspect the gas is leaking.
Turn off the gas supply valve of your propane tank if it is safe to do so.
Once away from the leak, contact your propane supplier. If you can’t reach them, call 911.
Do not return to the area until your propane retailer, emergency responder, or qualified service technician determines it is safe to do so.
Get your system checked. Before you attempt to use any of your propane appliances, your propane retailer or a qualified service technician must check your entire system to ensure that it is leak-free.

Do Not Run Out of Gas! Yes, Running Out of Gas Can be Hazardous

Serious safety hazards, including fire or explosion, can result. If an appliance valve or a gas line is left open when the propane supply runs out, a leak could occur when the system is recharged with propane. Air and moisture could get into an empty or depleted storage tank, which can cause rust build-up inside the tank. Rust can decrease the concentration of the odor of propane, making it harder to smell. If your propane tank runs out of gas, any pilot lights on your appliances will go out. This can be extremely dangerous if not handled properly.

Consider Installing Propane Gas Detectors

In some circumstances, you may not smell a propane leak. Propane gas detectors are designed to sound an alarm if they sense the presence of propane. Their operation does not depend on the concentration of odorant in the air, just the propane concentration at the detector. We recommend that you consider installing one or more propane gas detectors. This is important if you or others in your home have difficulty smelling propane, or if appliances are in little-used areas in your home where the smell of propane might not be detected. Detectors can provide an additional measure of security. Propane detector quality is important, so be sure the units you buy are listed by Underwriters Laboratories (UL). To be sure propane gas detectors operate properly, install and maintain them as the manufacturer recommends. Even if you install gas detectors, have a qualified service technician inspect your propane system and propane appliances periodically. You may also consider a carbon monoxide alarm to be extra safe.

Ultimate FAQ Guide to Propane

Q: Where does propane come from?

A: You’ve seen propane tanks at your favorite hardware store, and have probably used it to grill up some tasty food at a summer barbecue. But have you ever wondered how propane is made. Propane is a fossil fuel that’s found naturally, alongside natural gas and oil. Propane is separated from natural gas during processing, often using refrigeration—so contrary to popular belief, propane isn’t made from natural gas but is extracted from it. Propane is also extracted from heated crude oil using a distillation tower. Once the propane is isolated, it’s pressurized so it can be stored as a liquid in the cylinders and tanks you see in cages at retail locations nationwide.

Q: What is propane used for?

A: Propane is an extremely versatile fuel that is useful in a wide variety of applications. Home propane is commonly used for home heat, cooking, and water heat, especially in rural areas where natural gas isn't available. Since propane grill tanks are portable, efficient, and powerful, they're often used in your favorite outdoor spaces for the staple barbecue grilling, for patio heating and lighting, pool and spa heat, and outdoor kitchens.

Q: Is propane dangerous to the environment?

A: No. Propane is an approved, clean fuel listed in the 1990 Clean Air Act and the Energy Policy Act of 1992 and is one of the cleanest burning of all fossil fuels. Tests conducted by the U.S. Environmental Protection Agency show that propane-fueled vehicles produce 30 percent to 90 percent less carbon monoxide and about 50 percent fewer toxins and other smog-producing emissions than gasoline engines. Propane also is nontoxic, so it’s not harmful to soil or water.

Q: Is propane convenient to use?

A: Yes. Up to 56,000 miles of pipeline and more than 6,000 retail dealer locations make propane readily available throughout the United States. Because propane is stored in portable tanks, it can also be used in areas beyond gas mains. To fuel homes, large tanks can be buried underground because propane is a nontoxic, nonpoisonous fuel that doesn’t contaminate aquifers or soil. Refueling a propane vehicle takes about the same time as refueling a gasoline vehicle. And propane is the only alternative fuel with fueling stations located in every state.

Q: Is propane a natural gas?

A: Propane is one of the cleanest, most efficient, and most versatile fuels. It is an alternative fuel source that continues to grow in popularity as it is environmentally friendly and emits lower levels of greenhouse gas emissions into the atmosphere. Propane is a by-product of natural gas processing and crude oil refinement. It is produced from liquid components recovered during the processing and refinement of natural gas and crude oil.

Q: What are the disadvantages of propane?

A: Propane is more compact than airborne. When there is a leak in a propane fuel tank, the gas may begin to sink into any enclosed area and thus pose a risk of fire and explosion.

Q: What are the characteristics of propane?

A: It is non-toxic, colourless and nearly odourless. Like for natural gas, a distinguishing odour is applied so that the gas can be identified quickly. Propane exists as oil, as well as gas. It is a non-toxic, colourless and odourless gas at atmospheric pressure and temperatures above –44 F.

Q: What is the condensed structural formula for propane?

A: Methane is the simplest alkane, with the molecular formula CH4. The carbon is the main atom and forms four single covalent bonds to the atoms of hydrogen. The condensed formula for propane will be C3H8.

Q: What is carbon monoxide?

A: Carbon monoxide (CO) is a colorless, odorless, tasteless, and toxic gas. Smoking a cigarette; idling a gasoline engine; and burning fuel oil, wood, kerosene, natural gas, and propane all produce CO. High levels of CO can be produced when fuels are burned incompletely.

Q: What are unintentional release measures for propane?

A: Personal Precautions: Evacuate the area immediately. Isolate the hazard area. Keep out unnecessary and unprotected personnel. Evacuate downwind locations. Eliminate all ignition sources. Use grounded, explosion-proof equipment. Distant ignition and flashback are possible. Monitor area for flammable or explosive atmosphere. Before entry, especially into confined areas, check the atmosphere with an appropriate monitor. Test for sufficient oxygen levels.

Methods for Containment and Clean-up: If possible, turn the leaking container so that gas escapes rather than liquefied gas. Contact emergency services and manufacturer/supplier for advice.

Other Information: Contact supplier, local fire and emergency services for help. Report spills to local health, safety and environmental authorities, as required.

Q: What is propane used for?

A: Its main uses include home and water heating, cooking and refrigerating food, clothes drying, and powering farm and industrial equipment. The chemical industry also uses propane as a raw material for making plastics and other compounds.

Q: Are gas and propane the same thing?

A: For homeowners, the main difference between the two is that propane is compressed into a liquid form and either sold in portable canisters, or delivered via truck to a permanent storage tank on their property. Natural gas, however, remains in its gaseous state and is delivered to the home via a pipeline.

Q: Is propane gas normal gas?

A: LPG and Natural Gas are chemically different gases. Natural gas is methane gas whilst LPG (liquefied petroleum gas) is propane or butane, usually sold as bottled gas. LPG and natural gas have different energy content and gas/air mixes for combustion and working pressure.

Q: What is the difference between propane and LPG?

A: Generally, the acronym LPG and the word propane are interchangeable, with propane being the preferred term in the United States and LPG preferred in Australia and New Zealand. Propane has a lower boiling point than butane at -42°C vs -0.4°C.

Q: Is propane toxic to humans?

A: Propane vapor is not toxic, but it is an asphyxiating gas. That means propane will displace the oxygen in your lungs, making it difficult or impossible to breathe if exposed to high concentrations. If you suspect you have inhaled a significant amount of propane, call 911.

Q: What uses propane in your house?

A: Propane is an incredibly versatile fuel. In the home, it is most commonly used for heating and powering certain appliances. Stoves, barbeques, water heaters, clothes dryers and more can all run off propane. If the home has only been recently converted to propane, however, not all appliances may be using it.

Q: Is propane safe to use indoors?

A: Yes, it is safe to use a propane stove indoors. However, there are a few safety precautions to take if you have an indoor propane stove. Like any cooking appliance, the key element in successfully using a propane stove is ventilation. Any stove that relies on an open flame releases exhaust into the indoor air.

Q: Is propane or electric cheaper?

A: According to the U.S. Department of Energy, heating a home in the U.S. with a propane heating system costs far less than heating with an electric system. In addition, over time, propane water heaters can cost one-third less to operate and heat water twice as quickly as electric water heaters.

Q: What are the hazards of propane?

A: As for natural gas, propane is non-toxic. However, it presents a possible inhalation hazard if released in a confined space, as it displaces oxygen and acts as a simple asphyxiate. Liquid propane is an effective refrigerant. It rapidly absorbs heat from the skin and can cause severe burns to the body.

Q: Which is better natural gas or propane?

A: Propane is usually more expensive than natural gas on a per-unit basis, but it's also much more efficient. In fact, propane produces about twice as much heat energy as an equivalent amount of natural gas. While propane is measured in gallons or liters, you'll find natural gas measured in cubic feet or cubic meters.
