and bhp is testing what new technology now, page-7

I suppose this is what we already surmised, but it is good to see it being written about outside HC.

Re timeframe to build LTR, I would guess 18-24 months. There is a big difference in the engineering of the demo model vs. a commercial unit..... size, longevity, operating cost amongst other things.

It doesn't matter too much if the little demo unit warps a bit with heat. If you're building a full scale plant you need to worry more about things like refractory lining and maintaining the structural integrity.

Also, it doesn't matter too much if the demo plant loses energy out the stack... as long as you get data to base future design parameters on. With CS, you would need to optimise such losses.

Fortunately this stuff is easy to fluidise and fluid bed furnaces using sand as the media are a well trodden path.

I'll be getting REALLY excited when we see the 96% TiO2 and fresh hydrochloric out of Newcastle. Better put the Ben Ean on ice right now....
