All decaffeination processes are performed on unroasted (green) coffee beans, but the methods vary somewhat. They generally start by steaming the beans. The beans are then rinsed in some solvent. The actual solvent depends on the process, but different methods use either methylene chloride, ethyl acetate, liquid carbon dioxide or oxygen, or just good ol' water. The process is repeated anywhere from 8 to 12 times until it meets either the international standard of having removed 97% of the caffeine in the beans or the EU standard of having less than 0.10% caffeine by mass in the coffee at the end of the process.

Using water is one way to remove the caffeine (osmosis)... Know what they do with that caffinated water? Sell it to soda companies to add to their products
yes, there is a little amount of caffeine (less than 1%), so there is no such thing as a 100% caffeine free coffee bean.

Caffeine is removed from the coffee beans - there are various processes to do so.

Decaf coffee does have miniscule amounts of caffeine, but I don't know how they get the rest out.
