We can use absorber with MDEA, DEA, etc and also selective membranes. @selly cipta:

first, Sulphur (S) in coal causing burnign not perfect,
can you describe any method to reduce (S) in coal?? thanks

In proceedings before regulatory bodies that must approve permits, cost is THE issue! Even the most basic of engineering texts address cost, and with efficiency costs of carbon capture (remember, transport and sequestration doesn't exist yet, and would be even more costly), it's got to be considered. Cost wise, there's no way to build a coal plant going forward, and engineers are the ones with the tools to grasp this and get us to sustainable energy sources. Costs? OK, that'll be coming up next, it's intense, on my blog but transferring that info will take a bit. One moment please... because you (plural, all readers!) MUST consider costs.

I just give a resume on technical things and not looking at the cost and all.. maybe u could send a post here considering this.. hehe.. it's all-about-coal month!! don't miss it.. thank you..

It's so costly that industry models, when considering IGCC capture, will select a "Cap & Trade" option instead! And remember, there isn't a single IGCC plant (electrical generation) in operation doing capture, much less capture AND TRANSPORTATION AND STORAGE!
