Regenerable SO2 Scrubbing System
Regenerable SO2 Scrubbing System
(OP)
I wonder if a regenerable sulfur dioxide (SO2) scrubbing process would be a suitable option for cleaning combustion gases from refinery heat and power generating plant. Currently, there are two leading technologies in this area: Cansolv and Belco. However, as far as I know neither has been used in such application (so far they have been used for SRU, FCCU or FCU tail gases).
Is this a matter of huge volume of combustion gases?
If so, would it be possible to split gas stream and use a few absorbers working in parallel?
What do you think?
Has anyone any experience with regenerable systems for SO2 removal?

What are you burning for a fuel source? Amine treating on the front end would be a little more typical approach for a refinery unless you're burning fuel oil, coke or something like that.

What would be the economics of regenerable SO2 scrubbing compared to traditional approach with lime slurry as an absorbent and large quantities of calcium sulfate as a by product?
I haven't heard about regenerable system treating more than 500 000 Nm3/hr. That is why I asked if using a battery of a few absorbers working in parallel couldn't be a suitable approach to overcome this problem.

How about building a coker or resid hydrocracker and turning these streams into light products?

I think Kittiwake has something to do with this.
