Just wondering if any knew how many litres of petrol come form one barrel of crude oil?

Cheers

Cupramax

A barrel of crude contains 42 gallons. Not sure if thats US or Imperial gallons. 4.5 litres to an imperial gallon, you work out the rest...

Jiggerypokery

Edited! 159 litres of crude oil in one barrel (not petrol).

Jiggerypokery

That's US gallons.

OllyK

Yes but crude to petrol is not 1:1, the raw crude is distilled and some it comes out as petrol, some as derv, heavy oils and so on right down to tar. The percentage make up of the crude will no doubt vary depending on its source. So I suspect the answer to the questions is "how long's a piece of string". No doubt imlach or somebody could provide an approximation

Breakdown of a barrel as follows...

What Does One Barrel Of Crude Oil Make?

QUICK STATS
- One barrel of crude oil contains 42 gallons
- About 46% of each barrel of crude oil is refined into automobile gasoline
- In the US and Canada an average of 3 gallons of crude oil are consumed per person each day
- The US imports about 50% of it's required crude oil and about 50% of that amount comes from OPEC countries


Product Refined Gallons/Barrel
Gasoline 19.3
Distillate Fuel Oil (Inc. Home Heating and Diesel Fuel) 9.83
Kerosene Type Jet Fuel 4.24
Residual Fuel Oil 2.10
Petroleum Coke 2.10
Liquified Refinery Gases 1.89
Still Gas 1.81
Asphalt and Road Oil 1.13
Petrochemical Feed Supplies 0.97
Lubricants 0.46
Kerosene 0.21
Waxes 0.04
Aviation Fuel 0.04
Other Products 0.34
Processing Gain 2.47

Depends on the quality of the crude oil and the efficency of the refining process

ajm

Taking the stats posted above (46%) it would be 35 * 4.546 * 0.46 = 73 litres

35 imperial gallons per barrel
4.546 litres per gallon

Hmm.. so they're makin a few quid all the same lol cheers lads

That's amazing how little aviation fuel they get... Why do people go on about cars when they could talk about the demands of air travellers/freight?

Faire D'Income

I'm not following your point but if the Aviation fuel is kerosene based, then it's JET A1 which is not taxed at all. If it's AVGAS then the duty/tax levels are similar to forecourt fuels.

Brendan Hughes

No, not a question of tax, but more of the supply/production efficiency I suppose. I didn't think much about what I typed (before you give me the third degree on it ), but it seems striking just how many barrels of oil you have to produce in order to get a respectable amount of stuff that powers planes - whether "jet fuel" or "aviation fuel" - particularly given how much they use. Perhaps the amount of litres per passenger per km flown, compared to litres per passenger per km driven, is the same as there are so many more road miles, I don't know. Just thought that, from those figures, it should be the airlines rather than the road lobby that should be up in arms if there's an oil shortage.

Faire D'Income

I don't know. Either there is less demand for Aviation fuel and hence less produced per barrel or in the case of JET Fuel A the higher kerosene content is harder to extract. Certainly in the case of AVGAS I'd have thought it was largely due to the lower quantities used (compared to cars) and also the higher lead content.

The answer to that is threefold. Firstly, the major airlines such as BA and AA have introduced a surcharge of around £5.00 per passenger to cover any increases. Secondly, they will have hedged to some degree and bought forward which will minimise their exposure and lastly there is mounting pressure for them to pay tax on JET Fuel A, so they'll not be wanting to antagonise too many Governments as it will only increase their exposure to negative publicity.

In round figures Brendan, it will take about 40 tons of jet fuel to get 150 passengers to New York from Heathrow. Tax free fuel of course. Lot of greenhouse gases there!

How many litres are in a ton?

imlach

1000 in a metric tonne (1 litre = 1kg)

ajm

Thats for water, Avgas has a density of about 0.6 kg per litre, so 1667 litres per tonne (maybe slightly denser for Avtur)

imlach

Oops, yes, should have read the context of the question - doh

Echo

So what's the average MPG per average passenger on say a London to New York flight? Just curious :-)

imlach

I'm fairly certain it's slightly less than if everyone drove the same distance....

Back of postcard calc....

40 tonnes @ 1667 litres/tonne = 66680 litres.

150 passengers, therefore 444 litres/person.

444 litres = 98 gallons/person.

Is it 2500 miles London to New York? Therefore, 25mpg/person.

Interestingly, if each passenger had to pay that in terms of automotive fuel, that'd be about £500/person.....yet flying the Atlantic can be done for £200+.

If aviation fuel was to be taxed, imagine how much prices would go up by!!

fast bloke

its more than 2500 miles

p.s. - It might not be but I needed the corner

Brendan Hughes

Thanks for doing the calculation, I was going to work it out. But don't forget you can get 4 people and luggage in one car...

Echo

I was sitting at the airport in Beijing waiting for my flight home and was struck by the fact that the 747 that turned up had just done the flight from London and just got a hoover and fill up before flying back. That must have been about 15,000 mile round trip - and no cam belt change :-)
