"Saudi extra barrels wrong kind of crude!"

big_rc asked:

"what do the refineries do with the sulphur they remove from the oil?"

so I made this web page:

http://www.cuug.ab.ca/kmcclary/sulfur/

Nice work Keith!

More from here.



And here.

This website never ceases to amaze me. I learn something new almost everytime I log on here.

Thanks for the info !!

great webpage!

Very informative clear and it gives you the idea within half a minute

my compliments

Russian Scientist Suggests Burning Sulfur in Stratosphere to Fight Global Warming

Just to put this in perspective, the amount of sulfur he is proposing to burn is about half of this stockpile:

http://www.cuug.ab.ca/kmcclary/sulfur/

BTW, the stockpile has been almost all melted down and shipped away in the year since I made the webpage.

Lets see, am I hearing this right?
We removed all the sulfer from our oil to save the air,

Now we have to burn it in the air to save the planet?

Who screwed this one up?


But by Removing all the sulfer from the oil processing refineries to SAVE the ecology, we have then caused the global warming?

Reminds me of ants I saw when I was little, a couple thousand were stacking up sand in one area and another couple thousand were unstacking it. the unstackers were winning.

But reality is probably the truth:
Russia probably has high sulfer oil, and it is expensive to extract it, so the Russians paid a scientist to come up with a reason for leaving sulfer in the oil and this is their explanation, thus raising Russias high sulfur oil value with the stroke of a pen.

Hey I could become a politician.
Except I would have to overcome my problem with honesty.

Sulfur in other fuels causes acid rain. I guess it's only sulphur in the stratosphere that is "safe". Of course, it may not be so safe after all. In the end, it all depends on whether the remedy is worse or better than the disease.

Much of our natural gas is loaded with hydrogen sulfide. Evil, deadly gas, second only to HCN in toxicity.

The old way was to use a process to remove it from the gas using an amine process similar to that used to remove CO2 from gas. THe H2S was then burned in a flare or candlestick incinerator. (H2S is very flamable) this resulted in a lot of SO2 emissions. (not to mention the H2S that was not burned.

More modern methods used something called a Sulfur Recovery Unit (SRU) Sulfur had economic value for use for fertilizer and such. In the Klaus process, 2/3 of the H2S was burned in the air to make SO2, then reacted with the other 1/3 of the H2S on a catalyst to make elemental sulfur and water. Pretty slick. The tail gas from this process was run through the flare or candlestick as above.

Since Sulfur is bad for our planet, efforts have been underway to reduce the amount released into the air. The above two process have been limited by both environmental regulations and a glut in the global sulfur market. It's hard to get rid of sulfur nowadays.

So, the more modern method is to strip the H2S out of the gas, then reinject it into the ground. The H2S is 40% or more, balance CO2, then run down a wellbore, and gone.

One of the more interesting places I've been liquifies the H2S prior to reinjection. The same place scavenges the waste gas from the processing of NG and runs a pretty big power plant of the waste gas.

On another note, most of the CO2 stripped from gas (and it is a LOT of CO2) is blown into the sky as a waste product. The above mentioned plant shipped their waste CO2 hundreds of miles (pipeline) to reinject into oil-bearing formations to improve production. I'm not going to name them by name, but they don't (publicly) believe in PO. Although they are a very large and very evil corporation, they eat every part of the buffalo.

Another place I worked at took H2S from a nearby NG processing plant, then burned it to make SO2>SO3>(H2SO4) (Anhydrous sulfuric acid).

Pretty scary stuff. They took this and put it into a reactor with common salt (NaCl) to make HCl gas> hydrochloric acid. This was used to pour down oil wells to dissolve limestone and improve production.

This was, and is, hands down, the most dangerous place I've ever been.

I only got gassed by the HCl when the line feeding the RV to the tails scrubber blew, but I barely made it out before I passed out. The H2SO4 contaminates in the gas cloud dissolved my tee-shirt. Were it not for my air-pac, I probably would have died. Rumor has it that people came off the tower only wearing their zipper.

(BTW, this plant was in the US, it was closed in 1999 when low oil prices killed the demand for HCl)

You mean Kerr-Mc Evil?

Close, but no.

XOM

Had some good times with kermac too.

Glauber's Salt can be used to make a very effective heat storage system.

Keith_McClary, you can add your webpage here Wood products woodworking industry directory

I think it is very informative!

From the Green Chemicals Blog
"..according to researchers from the US Department of Energy's Argonne National Laboratory and Ontario, Canada-based Kingston Process Metallurgy Inc. (KPM), you can also extract pure hydrogen from the hydrogen sulfide that naturally contaminates unrefined oil including oil sands."

IMO, this is significant, because :
1. Sulfur production (and conversely H2 production) from oil-sands projects could approach tens/hundreds of tonnes of sulfur/d.
2. The Claus process currently used to produce sulfur from hydrogen sulfide (H2S) uses air, resulting in the hydrogen being converted to water. This H2 can be recycled back to the processing steps in the process, decreasing the need for converting natural gas to supply the hydrogen.

one of the use of sulfuric acid is when concentrated at 98% to dry stuff , at such high concentration it is not corrosive and can be kept in normal steel tanks , but it is deadly , fear is the proper attitude when handling this tiger

Sulfur is not bad for the planet ,
plants use it to grow and there is no problem there ,
the sulfur in the oil came from the vegetation
you can treat your garden with it , plants love it

the problem is local excess and the form ,
usually sulfur dioxyde is OK but if too concentrated instead of making the rain lightly acid it become concentrated acid ,
morning mist in the valleys is even worst , rain doesn't wash it down
the mist droplets have been recorded at PH 1 , that's a killer
a pity because the production of SO2 is probably the biggest climate modifying gas humans produce and yes

...... it's a cooling effect

I've worked with sulfuric and sulfurous acid SO2 ,SO3 and H2S , this last one is an integral bastard

It make steel brittle and develop cracks , brass is destroyed too
so it tend to leak

It's explosive , quite violently too and will maintain a fire with toxic smoke

It stink , when it doesn't either there is none or there is so much your nose is desensitised and your going to die !
