Abstract:
1. An apparatus for the tangential introduction of a stream of a gas-loaded absorption liquid into the top of a regeneration column of a unit for acid gas scrubbing, wherein the regeneration column has a radial feed line, the apparatus comprising a feed tube disposed within the regeneration column and fluidically coupled to the radial feed line, the feed tube having a first tube bend proximal to the radial feed line and a second tube bend distal from the radial feed line, both tube bends being characterized by angles of curvature of less than 90°, wherein the second tube bend is curved contrarily to the first tube bend and is arranged such that an outlet orifice of the feed tube is situated adjacent an inner wall of the regeneration column, thereby allowing the gas loaded liquid stream to exit the feed tube into the regeneration column essentially tangentially to the inner wall of the regeneration column.
