Sulfur Degassing

This is outside of my field, but the first thing that comes to my mind is to pass the vapors through a water spray air scrubber. You'll get sulfuric and sulfurous acids, which are marketable if sufficiently pure and not too far from the customer to transport economically.

should take care of all your problems and allow you to produce saleable elemental sulfur or sulfuric acid (Currently demanding high prices).

tell Gary that Mike sent you.

seriously, you should look into this technology.

I once looked into adsorbing the SO2 using shredded waste newspaper.

SO2 was then extracted as a concentrated stream using higher temp exhaust to desorb it.

This concentrated stream could then be turned into sulfurous or sulphuric acid.

The process showed quite a bit of promise.

Obama Administration will use EPA to further regulate "greenhouse gases". But because of the "Cap and Trade" recommendations there will actually be no reduction in gases just a shuffling around of dollars.

Extortion and Politics. Where is the demand that China reduce it's emissions? It build coal fired power plants every week and use no emissions controls and whatever coal they dig up to burn, no matter the sulfur or mercury content.

Until the now biggest user of coal (China) does something about their emissions, there will be no change.

jghani,

Did you ever find your solution for Sulphur degassing?

We have the solution. Need a customer to actually try it. Seems like sulfur dioxide is not a problem anymore as mercury is the element of the day to be targeted.

One available option is to use a system that can re-route the stripping air back to the sulfur plant. The D'GAASS system from www.goarallison.com claims that it can achieve less than 10 ppmw (H2S+H2SX) in liquid sulfur, with the ability of routing the stripping air back to the sulfur recovery unit. The stripping air recycle would increase overall sulfur recovery and potentially eliminate a point source of SO2.
