Why can propane cause explosion?

Answer 1

Propane heats ammonia and water in solution in a generator, the ammonia is separated from the water in a separator. The water is sent to an absorber to re-absorb "used" ammonia. The ammonia rises to a condenser where it cools and condenses. It then is mixed with hydrogen in the "evaporator" coil inside the refrigerator where it chemically combines with the hydrogen, evaporates and cools, allowing it to absorb heat from the refrigerator. This mixture then passes to the absorber where the ammonia is absorbed by the water and the hydrogen is released for reuse. The ammonia water mix is then returned to the generator to repeat the cycle. Without heat added at the generator the cycle will not have any "motive" force, and stops until heat is reapplied.

**The chemical reaction of ammonia 2(NH3) + H2 ---> 2(NH4) converts liquid ammonia to gaseous ammonia, and creates the cooling effect.

The absorption of this gaseous ammonia by water releases hydrogen, for this reaction.

Answer 2

Propane is used as fuel in cooking on many barbecues, portable stoves and in motor vehicles. Propane powers some locomotives, buses, forklifts, taxis and ice resurfacing machines and is used for heat and cooking in recreational vehicles and campers.

Answer 3

Propane takes a couple of forms. It could be C3H8, the alkane with three carbon atoms that fits in the series with methane, ethane, propane, butane, etc. Additionally, it could be the combination of this and a few other hydrocarbons to form the combustible fuel we use in the backyard barbecue, in some vehicles, and as a fuel source for cooking and heating in some structures, particularly more rural or remote ones.

Propane is a hydrocarbon, and is a molecule of carbon and hydrogen. It is stable, but it is flammable because if it is heated sufficiently in the presence of oxygen, the hydrogen atoms will "abandon" the carbon atoms and combine with the oxygen atoms to form water. The carbon atoms will combine with oxygen to form carbon dioxide (or perhaps some carbon monoxide). All of these reactions allow the atoms involved to "recombine" in other configurations, as you can see. And the reason atoms will chemically react to combine with others atoms is largely driven by the fact that the atoms involved can move into lower "final" energy states by changing the way they are bonded. This "desire" or "drive" of atoms to enter into "combinations" or create new chemical bonds based on the fact that they can, in their new forms, end up in lower energy states, is a driving force behind most chemistry.

If you have a room full of (a sufficient amount of) propane mixed in with atmospheric gas (which is about 1/5th oxygen) and you introduce a spark, there will be a blast. The spark will initiate combustion, and it will proceed so rapidly that an explosion will occur. The hydrogen and carbon will "bail out" of their former chemically bonded existence. They'll form new bonds with the oxygen, liberate lots of energy (which you will definitely notice), and move to a lower energy level at the end of the reaction. If you flow the gas through a jet to mix it with air, and allow it to move from there through a burner, you can get a controlled flame to cook or heat with. In nature, a general rule is that things that can move to a lower energy state will "always" try to do so.

Answer 4

It expands if the container allows it to, and in any case, like all other gasses, increases its pressure on the container walls.

It cannot "burn" unless there is oxygen in the mixture, and unless it is at ignition temperature (which is not specified where I searched for details). In any case, Propane becomes liquid at -47C, so in the bottle it's under pressure, but equivalent to that temperature. Warming it up, builds the pressure on the propane to evaporate.

An interesting question is what happens to prapane in a hot air balloon. Propane gas is heavier than air, and therefore travels downward. Heated propane may have LTA properties, but I wouldn't know who to ask.

Answer 5

Propane is a highly flammable gas. If it is mixed with air it will burn extremely quickly, causing an explosion. Since propane is commonly stored under pressure in liquid form, propane cal also produce a BLEVE (boiling liquidexpanding vapor explosion) in which a tank is heated and liquid propane boils, increasing pressure inside. Eventually the tank explodes and the released propane ignites, producing a fireball.

Answer 6

propane is a combustible gas, and when sparked, creates a flame. which burns at around 1995 °C/3623 °F

Answer 7

At normal pressures propane is a gas. It is compressed for storage and transportation in tanks.

Answer 8

It is derived from other petroleum products during oil or natural gas processing.
