Abstract:
1. A system for regeneration of species removal media with precipitates comprising: a regenerator comprising: a process stream inlet for receiving a process stream comprising rich unwanted species containing precipitates; a downcomer standpipe column into which the process stream is directed; an internally circulating liquid stream of species removal media comprising chemical solvent; and a set of inverted bayonet tubes located inside of the regenerator and heated with a heat media, the heated set of inverted bayonet tubes transferring heat to the chemical solvent; an overflow system for recovering regenerated lean chemical solvent from an overflow arrangement and storing the regenerated chemical solvent in a lean chemical solvent surge tank; a cooling system to cool an exiting gas stream from the regenerator with the process stream, wherein the exiting gas stream is formed upon interaction of the process stream with a rich concentration of unwanted species and the internally circulating liquid stream; and a condenser for regenerating the chemical solvent.
