What is propane derived from?

A unique feature of propane is that it is not produced for its own sake, but is a by-product of two other processes, natural gas processing and petroleum refining.\nPropane is removed from natural gas to prevent it from liquidifying and causung problems in natural gas supply lines.\nWhen crude oil is processed into gasoline and other products, some propane is also formed as a by-product.

It varies with the grade produced.  This example is is 94.5 nitromethane with nitroethane and nitropropane.  I doubt there is any measurable amount of propane left in the commercial product.

It's a monomer derive from petroleum , exactly how I am not sure  since I only do plastics.\n\nThe monomer is receive as is for polymerising to make   ,  pe , polyethylene.  Which makes the our plastic bags and some hoses (aquarium hoses).\n\nOn the re-cycle logo you can see "pe" , because today we have to declare. \n\nWhen the primodial bog sinks and plants turn to gas , petroluem and coal , ethylene is somewhere in there.\n\n** therefore the energy is solar at source , origin.

No, not likely. \n\nCoal is formed from (coalified) plant material. Petroleum and natural gas are formed from organic remains of plants, primarily microscopic phytoplankton, and small marine animals called zooplankton. \n\nIn the rare instance that a dinosaur's dead body might have been carried by water into an oxygen poor (anaerobic) environment and quickly buried by catastrophic deposition of shales, there might have been some protein or lipids from that carcass that eventually converted to oil, but it is far more likely that the body of a large organism like a dinosaur would become food for decomposing bacteria and other scavengers long before it had the opportunity to be converted to oil by the process of heat and pressure known as catagenesis.\n\nThere is no truth to the answer that the "traditional theory is that petroleum formed during the same period as dinosaurs" as most of the world's petroleum reservoirs are known to be younger than that, and many are known to be older. One deposit of oil has been found that is only about 4,000 years old. \n\nDr. Thomas Gold's hypothesis of abiotic oil has never been substantiated by any evidence of oil that is NOT from biological sources.  Very few geologists agree with Gold, and none have been able to prove he was correct. There is considerable evidence in the form of molecular structure, isotopic fractionation, and more that proves that little if any oil is from the abiotic mechanism Gold hypothesized. The big problem with Gold's hypothesis is that oil and gas ARE NOT found in igneous rocks, as one answer here suggests.\n\nI'm a petroleum geologist.

that's bad...  Methane is CH4, propane is C3H8, and octane is C8H18... the rule to find the number of H in an alkane (single bonded Carbons) is 2N+2 where N is the number of carbon atoms... Methane is 1, ethane is 2, propane 3, butane 4, pentane 5, hexane 6, septane 7, octane 8, nonane 9, decane 10, etc....

The CO2 simply displaces another gaseous product.  CO2 is used because of its low cost, high expansivity, and fairly low reactivity.  Some of it is returned to surface with the gas.  In fact there are wells in Utah that produce 60 % and higher CO2 with the gas.  These haven't been developed due to the expense of separating the two.\n\nOther means of "production enhancement" (what we call it), is water injection to displace gas, hydraulic fracturing to increase the overall reservoir tapped by a single well, chemical treatments to increase permeability of the formation rock, and formation mapping.  With modern computing power and technology, it is possible to drill the hole to the ideal location to tap the best part of the formation.  It is even possible to reenter a hole with a drill, and directional drill to a new formation.\n\nThe idea of oil being derived from geological sources is not new, and actually has some followers (even among those that should know better if its baloney).  What gets me is that it is can't be shown definitively either way.  \n\nIt could also be from sources we haven't really thought of, such as subterranean bacteria.  We only recently have been discovering that bacteria can live in really hostile places, and they do occur in oil and gas wells.  They live in the water on the oil-water interface, and can produce paraffins and sulfides from the nutrients they get in the hydrocarbons.  They are typically thought of as being introduced into the well with the water.

You have not stated where these vapors are coming from or what their purity is, but in general propane vapors can be compressed, cooled and thereby liquified. At approximately 200 psi and 100 degree F. propane can be condensed from a vapor to a liquid. I say approximately, because propane seldom exists in the pure form but is usually mixed with small amounts of methane, ethane and butane.

Since propane has three carbon atoms the isomers could be\n\nCl(CH2)-CH2-CH3\nor\nCH3-CH(Cl)-CH3\nThe isomerism in it is structural or position isomerism.\n\n\nThe reaction is as under\n             SN2  \nC3H9 + Cl2 --------------> monochloropropane\n\nThe mechanism is Nucleophilic Substitution. It is usually SN1 that is Unimolecular substitution.

Natural gas primarily consits of methane, a hydrocarbonic gas that has a variety of sources, including swamps, cattle flatulance, insects, however it is generally produced from the decay of organic material and can be found in largest amounts in underground deposits (Russia is sitting on one of the biggest ones.)\n\nHow sustainable it is entirely depends on how much of a demand there is for it. It's a gas primarily used for heating and energy production, so therefore demand for it is really high, so high that it's questionable whether we'd be able to produce enough methane gas to meet those needs, beacuse right now we primarily get it from underground deposits.

Glycerol is also known as propane-1,2,3-triol, formula C3H5(OH)3, so the answer is three.

Assuming ideal gas behavior, we have that the molar density (moles per unit volume) of a gas is given by:\n\nmolar density = n/V = P/(R*T)\n\nwhere R is the gas constant = 62.363 (liter*torr)/(mol*K) -see source\nP is the pressure\nT is the absolute temperature\n\nTo convert from molar density to mass density (mass per unit volume) we simply multiply by the molecular mass of the material in question.  In this case, the molecular mass of propane is 44.1.  \n\nPutting all this together, and plugging in values:\n\nmass density = (44.1 gm/mol)*(804 torr)/((62.363 liter*torr/mol*K)* (273.15+108)K)\n\nmass density = 1.492 gm/liter = 1.492*10^-3 gm/cm^3

Burn it like you burn any other hydrocarbon.  All hydrocarbons are just compounds that fit the formula\n\nCnH(n+2)\n\nFor n=1, it's methane.  n=3 is propane (used for barbeques, mobile homes as a fule source, or for camping stoves).  n=4 is butane, used in cigarette lighters.  n=8 is octane, which is a major component of gasoline.\n\nMethane is commonly called natural gas, and is piped into houses for gas stoves and furnaces (at least it is here where I live).  Hydrocarbons combust with O2 to give carbon dioxide and water vapor.\n\nMethane could be developed by organisms in bioreactors, but since there are also great stores of it in the ground from decayed matter (methane is a fossil fuel and a constituent of oil, and often found near coal deposits) generally we mine it rather than making it because it's cheaper that way.  perhaps if all the methane in the ground were used up, it would become cost effective to produce it rather than just mine it.

Paraffin is actually the final product to come from petroleum after a distillation process involving steam that separates the different components, or chains of hydrocarbons from the raw petroleum.  This is a process of distillation, separating, filtering and cleaning.

It is distilled from wood...turpentine comes from pitch-pine. Alchohol (methanol or grain) comes from plants. \nYou would need a 'still'...a covered boiling vessel with a condensing tube for the steam...\nMineral oil is from a common by-product of gasoline production, petrolatum...also known as vasoline. It might be more difficult to make.

Oxygen is produced usually as a gas or liquid from air by a method called cryogenic distillation. \n\nIt basically consists of cooling the air (which costs nothing as raw material) until it liquefies, and then distilling the different components (nitrogen, oxygen, argon, etc) as you would distill any other mixture.

Kerosene is obtained from the fractional distillation of petroleum at 150°C and 275°C (carbon chains from the C12 to C15 range).\n\nTypically, kerosene directly distilled from crude oil requires some treatment, either in a Merox unit or a hydrotreater, to reduce its sulfur content and its corrosiveness. Kerosene can also be produced by a hydrocracker, which is used to upgrade the parts of crude oil that would otherwise only be good for fuel oil.\n\nKerosene was first refined from coal by Atlantic Canada's Abraham Gesner in 1846, founding the modern petroleum industry in the process. Gesner went on to establish his Kerosene Gaslight Company to market kerosene around the world in 1850. Polish chemist Ignacy Łukasiewicz discovered the means of refining kerosene from the less expensive seep oil in 1856.
