off road diesel

But wait, the government stole 97% of the sulfur out of the diesel fuel I pay for and now my diesel engines all have 97% LESS lubricity and will seize up any day now.

Can I just toss a couple of chunks of elemental sulfur into the tank to prevent all the damage?

And ShyPup dangles the hook hoping to get a hit.

Your engines don't have 97% LESS lubricity since the old and new fuel meet the same lubricity standard. Chemical additives were added to the new fuel make things even. What you do have is less sulphur which means less pollution.

I don't think lubricity is the issue with sulphur. If it was then the lubricity would be different for both old and new fuels, and it isn't.

I will repeat one more time for those hard of hearing and reading:
Lubricity is not an issue with ULSD fuel. If you think it is then I have a bridge in Brooklyn that I will sell you cheap.


Isn't mental ping-pong fun.

How much sulfur did they put into the Brooklyn bridge?

 

[jayhaitch]

Why doesn't someone add sulphuric acid (muriatic acid) to their tractors tank and see if it improves lubricity?

Ultra Low Sulfur Diesel is derived through one of several processes the most common of which are known as "Hydrodesulphurization", “Severe Hydrotreating”, and “Severe Hydrocracking”. In these processes sulfur is stripped from the fuel through the use of low pressure or high pressure catalytic cracking. These processes remove sulfur through molecular manipulation via catalysts. It is important to note that in addition to removing sulfur this manipulation also has several negative consequences for the resulting fuel.

First, I want to concentrate on the loss of the sulfur and why this is important to you. Sulfur is an Extreme Pressure (EP) lubricant. It is regularly added to lubricating oils and greases to increase the lubricity and to raise the amount of pressure that the lubricant can handle before the lubricating molecular barrier begins to break down. Sulfur has always been a vitally important factor in providing lubrication to diesel engine fuel pumps, fuel injectors, and to a lesser degree engine valves.

So, what is being used to compensate for whatever lubricity was eliminated when the sulphur is removed? There must be something since ULSD meets the current specification for lubricity that has been in effect since January 2005.

We all know what sulphur helped do, but your comments appear to fan the flames that engines will suffer from the reduced sulphur. I doubt that will happen just because of what i just said, the lubricity in diesel fuel is remaining the same, albeit thru the use of substitute chemical additives put there by the refiners.

Oh, the sky is falling, the sky is falling.

Sheeesh, give me a break.

HENCE..its use in GEAR LUBE!! And the corresponding STINK of that type of lube....

In the refinery I work for, the Hydrotreating method is used. It is a high pressure operation were by hydrogen is added to the diesel fuel, it is heated and sent to the reactor where sulphur combines with the H2 to form H2S. The diesel fuel is then scrubbed in an amine scrubber to remove the H2S. The H2S is stripped from the rich amine and the resulting acid gas is sent to a Claus process plant to remove the sulphur. The sulphur is sold to a chemical plant that makes sulphuric acid. That's the simple explanation.

Elemental sulfur is selling for $15 US per ton, how many tons of sulfur diesel fuel additive should I purchase now to keep our tractors operating over the next 20 years?
