The main difference between propane and butane gas is their chemical structure. Although they are both composed of carbon and hydrogen chains, the number of carbons and hydrogens in each differ slightly. Propane, for instance, is composed of a three-carbon chain with eight hydrogens. Butane, on the other hand, has a four-carbon chain with ten hydrogens, which is only one carbon and two hydrogens more than propane.Know More
According to HowStuffWorks, propane and butane are the only two liquefied petroleum gases that have the ability to be stored in liquid form with moderate pressurization. This explains the similarities between their carbon-hydrogen structures. The slight difference between them gives each of the gases unique characteristics. For instance, propane gas has a boiling point of minus 44 F, which means that it vaporizes even at low temperatures. Because of this, propane burns clean and requires only a simple nozzle for vaporization. According to the U.S. Energy Information Administration, propane is most commonly used for residential and commercial heating, cooking fuel and petrochemicals.
Butane, however, has a much higher boiling point of 31 F, which indicates that it does not vaporize nearly as quickly as propane. Due to its higher boiling point, it has fewer uses. Butane is used for petrochemical feedstock and blending with propane and gasoline. It is most commonly used as lighter fuel and in the manufacturing of synthetic rubber for tires.Learn more about Outdoor
There are many different sizes of propane tanks, but the tanks commonly used for backyard barbecues weigh 37 to 38 pounds when full. Manufacturers stamp the weight of the empty tank on its collar after the letters "TW." These tanks hold approximately 5 gallons, or 20 pounds, of propane.Full Answer >
To inspect propane barbecues for blocked tubes or burners, remove the briquettes and cooking grids according to the manufacturer's directions, and visually inspect the tubes and burners on a propane gas grill for blockages. You need the owner's manual and approximately 5 minutes of time to visually inspect a readily accessible burner assembly on a propane gas grill.Full Answer >
The only accurate method of measuring the amount of propane remaining in a tank is by weighing the tank after disconnecting it from the grill, according to Ressler Propane. The most common tank for use on grills and other small outdoor propane appliances is a 20 pound tank, which weighs 38 to 40 pounds when full and 18 to 20 pounds empty.Full Answer >
A propane tank should be stored outdoors and away from a house or garage. It should be kept upright, away from heat and in a dry location. Before storage, it should be inspected to be sure it is in good condition.Full Answer >
