Fuel Oil and Diesel Unit Conversion

A ton is a ton is a ton is a ton.

But there is also short ton (907.1847 kg) and long ton 1016.047 kg.

enough distraction:

the clue is this one here.

Conversion factors discussed in the thread.

Dear Mr. abock,

The Calorific value should form the Basis. If You take the Calorific Value of Diesel as the Basis, then the Calorific Value of Fuel oil/Calorific Value of Diesel is the EQUIVALENT.

This is what I understand from your statement. Let us wait for other CR4 MEMBERS Views.

Thanks,

I have came across the calorific value equation. But is there any information eg. 1 MT = how many TOE.

Dear ahbok,

To my knowledge, no direct connection or equation between MT and TOE.

DHAYAYANANDHAN.S

TOE is a unit of energy. A MT is a unit of weight.

There is no direct conversion.

In a sense this is true, but if you look at the Wiki link I provided you see that there is a direct connection between both.

If I might quote from Wiki:

1 barrel of oil equivalent (boe) contains approximately 0.146 toe (i.e. there are approximately 6.841 boe in a toe).

• 1 t diesel = 1.01 toe
• 1 m³ diesel = 0.98 toe
• 1 t petrol = 1.05 toe
• 1 m³ petrol = 0.86 toe
• 1 t biodiesel = 0.86 toe
• 1 m³ biodiesel = 0.78 toe
• 1 t bioethanol = 0.64 toe
• 1m³ bioethanol = 0.51 toe^[3]Clearly a direct conversion. I just wonder why this would not come up in a basic research. Glad to be of help!G'day

If it's good enough for the OP, it's good enough for me.

Too bad the OP can't Google.

The first 2 bullets would mean density of diesel = 0.98/1.02 ~ 0.97 t/m³. But diesel is more like 0.85 t/m³.

Thanks guys for the links, I have googled, but all websites showing the conversion table, which don't address my query.

Not sure what your problem is. The Wiki link defines a toe = 41.868 GJ. Presumably you know the calorific value of the fuel oil and diesel, so you're there. You don't even need the densities. It's just CV (GJ/tonne)/41.868.

For estimates, I use 44 MJ/kg (= GJ/tonne) for CV of oil. Most hydrocarbons are around that figure on a mass basis. Also OK for gaseous hydrocarbons, methane is somewhat higher, but once past ethane they're all about same. On a volume basis higher molecular weight gases have higher CV as density is proportional to MW.

Can't remember whether 44 MJ/kg is lower CV (water produced remains as vapour) or higher CV (water condensed) and I haven't got data to hand. I think it's lower. The Wiki article doesn't specify, which I think is an important omission.
