How do oil and gas pipelines work? How does the fuel move through the line?

It’s a pressure system, using pressure the gas or oil is moved through the system, that’s why you cant have any leaks, otherwise you lose that pressure, and gas and or oil is pumped through the system properly. Also why you have an “Oil pressure” light or picture etc, on the dash, its moved by pressure, and the loss of pressure can lead to major problems.

simple the mecanic puts the air mesuring divice on the oil or water opening and seals it then puts in air presure and then waits a bit and checks the air presure so it works like a tire gage. if the air presure goes down then it it is leaking.

Most gas from oil wells is at very low pressure and must be compressed and treated before it can be sold. If the compressor or treating facility is under repair, sometimes the gas is burned until the facility can be restarted. Other times the gas pipeline may shutdown and it takes a while to shutdown the gas compression

I'm not sure your question makes sense.  Did you mean gas?  Gasoline reacts with oxygen to make lots of energy.  Water just dissolves a little oxygen.  You'll have to study chemistry if you want more detail.

Answer to the first part of thequestion;  \n\nConsider a water tank full of water.We connect a pump which pumps the water from the tank and delivers it again to the tank. \n The tank will never be empty and the water will be flowing continuously along the pipe connected to the pump and tank.\nIf the pipe connecting the pump and tank has an obstacle say a solid block of wood  which is somehow inserted into the pipe, then there will not be flow of water. But still the pipe and tank will have water but with out  any flow. \n Similarly in an electrical circuit electrons are like water in the tank ;the wire is like the pipe; the battery or cell or generator of electicity is like the pump in our example.\n Electrons flow from one end(tank) of the battery(pump) to the other end (tank) through the wire like water through the pipe.\n If one end of a wire is connected to the battery and the other end is left free,we have to imagine that the free end is further connected to the battery by an imaginary wire made of air.( The only matter that connects the free end to the battey is air) Just like water cannot flow through the wooden obstacle electrons cannot flow through air. Though the wire is full of electrons there will not be any flow of  electrons. \n\nAnswer to the second question,'Y dont they fall when they reach the end.\n\nThe wire is full of electrons even if there is no flow. We shall lift one end of the wire and let  the other end loose. It is natural to expect all the electrons in the wire to fall down due to gravity. But the electostatic force beeing very much stronger than the gravitational force keeps them within the wire. To remove them out we must apply a force atleast equal to the electostatic force. The function of the battery, in fact ,is  to provide such a force.

Distillation is a process by which a mixture of compounds is separated based on boiling point differences.  Crude oil is a mixture of many different organic molecules, which come in a wide range of molecular weights, which, in turn, leads to differences in boiling point.  So refineries take advantage of this by using many distillation processes in series.  One column operating at a relatively low temperature might separate waxes from more volatile compounds.  Another column, operating at a higher temperature, would separate light alkanes like propane and butane from heavier ones like hexane, heptane and octane.  Each of these streams might then go on to another distillation column or to some other method of separation.\n\nOn any given column, the distillate is the ligher, vapor stream exiting at the top of the column.  The liquid stream exiting at the bottom is called the bottoms.

In order for gasoline to produce power in an engine, it must burn under pressure. What happens is the fuel mixture enters a cylinder then is compressed by a piston to place the fuel under pressure. Once under pressure, the fuel is ignited to burn (explode). This drives the piston back down and the up/down motion of the piston moving is captured to use as power to drive a machine. This process happens over and over again very quickly within an engine.\n\nFour stroke engines work like this:\n1. The fuel mixture enters the cylinder while piston is going down \n2. The mixture is compressed while piston is going up\n3. Fuel is ignited (combustion) forcing piston down (this is the powerstroke)\n4. The spent gas/smoke is pushed out by piston going up\n\n\nTwo stroke engines take a short cut:\n1. The fuel mixture enters the cylinder while piston is being forced down from combustion (powerstroke)\n2. The spent gas/smoke is pushed out by piston going up\n\nSince the two stroke engine combines the intake and exhaust   steps they aren't as efficient. This is because there is still some smoke left in the cylinder during combustion, and some spent fuel being forced out with the smoke.\nThe four stroke engine purges the smoke before taking in new fuel.

You must already understand the displacement description so here's an attempt to physically understand the process.\n\nGravity pulls everything with mass  towards the center of the Earth.  This includes water and even air.  This is what creates air pressure and water pressure within a column of the fluid.  The force towards the center of the Earth is called the Weight.  Weight is simply the mass of an object multiplied by the acceleration of gravity (32.2 feet per second).\n\nMolecules in fluids can move around very easily.  They are constantly being pulled downward by gravity.  Generally, they are blocked by other fluid molecules already below them but they pile up and apply a pressure to the poor suckers below them.  The molecules at the bottom of the stack are under tremendous pressure in very deep portions of the ocean because they have to support the weight of the molecules above them.  (This also creates a sea level air pressure of 14.7 pounds per square inch)\n\nShips weigh less than the water they displace.  Gravity is pulling that ship down, trying to get it to the center of the Earth.  Once the weight of the water equals the weight of the ship, the water pushes back with enough force to keep it afloat.  Water molecules can flow easily.  When they begin to weigh more than the effective weight of the ship, they will flow beneath it and push the ship upward.

Natural gas comes from the ground like oil, except that it's a gas and not a liquid. There are pockets of it all over the world (again, similar to oil).\n\nIt produces electricity similar to a car engine. Some engines are designed to run on natural gas instead of gasoline. Once the engine gets running, it is hooked up to a generator which produces electricity.

Petroleum fuels are made of Hydrocarbons (molecules made up out of Hydrogen and Carbon).  When you combust/burn a Hydrocarbon in excess Oxygen you produce Carbon Dioxide and Water (incomplete combustion also produces Carbon Monoxide).\n\nTake gasoline for instance, mostly Octane (C8H18), the reaction shown below is the complete cobustion reaction which occurs,\n2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O\nThe fuel is chemically changed into Carbon Dioxide (which is not considered a fuel) and Water.  If we assume complete combustion, there is no fuel left over.\n\nIf you were to split up the Carbon Dioxide (or in your case CO that is produced through incomplete combustion), you will obtain elemental Carbon and Oxygen gas.  Carbon could be considered a fuel since it could then undergo further combustion with Oxygen however, it is not a Hydrocarbon fuel since it has no Hydrogen (all the Hydrogen went into water).

depends on the fineness of the sieve, because since water has a high amount of surface tension it can be put in a very fine sieve and not flow out of the holes whereas gasoline, having a very low amount of surface tension will flow through the holes. This is the same principle that gas/water separators in many engines work, the gas will flow through the screen but the water has a very hard time flowing through it and so it doesn't flow through it and stays in the tank.

when oil is burning it makes a lot of heat. This heat is used to transform water into steam (like when you prepare tea) this stream has much more volume than the water and so has a lot of pressure. This pressure goes via pipes to a turbine an makes it rotate quite fast. On the turbine's axis there is an electrical generator (a bit like the dynamo on an old bicycle) that produce the electricity.\n\nIn the end you have to get rid of the steam typically by cooling in down or sending it into the atmosphere.

Natural gas is too hard to Compress, so, it is collected straight from the ground and pumped to homes. When a Gas field is found they just use a pipe like they do oil to tap into the Gas pocket. Butane is a gas that can be compressed it liquefies under pressure, that why a Lighter looks like it has Liquid in it, you CAN NOT do this with natural gas. This a easy way to explain it.

well the oil is under pressure, so when we drill all we are doing is releasing the pressure. Then when the pressure is gone there is still some oil left. sometimes to get out the oil we have to pump water down to force the oil up.\nSo it is not like you are left with any empty space if that is what you are thinking.\n\nthere are no consequences that I am aware of.

All hydrocarbons.  They start with gaseous methane (CH4) dissolved in the oily liquid, then through heavier dissolved gases with 2 to 5 carbon atoms per molecule, then liquids with every posible number of carbon atoms per molecule from 6 (benzene) to 8 (octane) to scores and scores, then waxes (the stuff of Vaseline) which have up to hundreds.  Sometimes there are sulphur-based impurities.\n\nRefining the oil is the process of separating the different weights of components.  Car and aeroplane fuel is roughly from C6 to C10, diesel fuel is heavier, and heating oils and lubricating oils are heaviest.

The oil is usually within a layer of porous material. Imagine a bucket full of marbles and water. You can get the water out of the bucket without disturbing the marbles much at all.
