A gas absorber, for removing at least one hazardous component from a flowing gas stream by contacting the gas stream with a lean liquid stream to absorb at least a portion of the gaseous component to produce a rich liquid stream comprising the gaseous component and a flowing gas stream having a reduced concentration of the gaseous component, comprises: (a) an absorber vessel [1], a double wall [2,5] forming an annulus, a top end [3], a bottom end [4], a means for restricting fluid flow into the bottom of the gas absorber from the bottom of the annulus and a means for passing fluid out of an upper section of the annulus into the gas absorber; (b) an inlet [5] for the lean liquid stream having a locus in the upper end of the vessel [1]; (c) an inlet [7] for the flowing gas stream located in the lower end of vessel [1]; (d) an outlet for the rich liquid stream having a locus in the bottom end [4] of vessel [1]; (e) an outlet [10] located in the top end [3] for the flowing gas stream having a reduced concentration of the gaseous component; and (f) at least one inlet [g] communicating with the lower end of the annulus in vessel [1] which inlet is used to introduce a lean liquid stream at least a portion of which flows upwardly through the annulus and overflows from the top of the annulus and thereby protecting at least a portion of the outer wall from contact with the flowing gas stream.
