1. An apparatus (1) for carrying out mass transfer processes, comprising a column (2) having at least two inlet pipes (3, 5) for introducing a gaseous phase,
wherein separation-active internals (9) are accommodated in the column (2) and a column section (29) extends from the at least two inlet pipes (3, 5) to the separation-active internals (9),
wherein in the column section a coverage of a cross-sectional area of the column (2) is less than 25%, based on the total cross-sectional area, and
wherein the at least two inlet pipes (3, 5) have a height offset which corresponds to not more than three times the largest inlet pipe diameter (6) and the at least two inlet pipes (3, 5) are at an angle (α) of from 60° to 150° to one another and have asymmetry with respect to one another,
wherein the asymmetry is given by the at least two inlet pipes (3, 5) each having different inlet pipe diameters (6, 17).
