| abstract |
The invention aims at enabling, in a catalytic decarbonation apparatus, inert particles coated with calcium carbonate to be constantly and systematically extracted from the reactor, with no risk of clogging the discharge pipes. Therefor, said pipes ( 7 ′a , 7 ′b ) have an inside diameter ranging between 40 and 60 mm and they have a downward incline up to their connection to an outside discharge conduit ( 8 ′), except, possibly, a horizontal portion starting from the orifice through which they emerge into the reactor ( 1 ′). |
