    • The present invention relates to a liquid-gas contacting unit (1) comprising a column (100), at least a lower packed bed (110) and a higher packed bed (120) positioned higher than the lower packed bed (110) inside the column (100), a gas-tight liquid collecting and redistributing device (130) disposed between the lower and the higher packed bed (110; 120) inside the column (100) and an external pipe (140) outside the column (100), the external pipe (140) comprising an inlet end (141), an outlet end (142) and a peripheral wall (143) between the inlet end (141) and the outlet end (142); the inlet end (141) being positioned between the lower packed bed (110) and the gas-tight liquid collecting and redistributing device (130) and the outlet end (142) being positioned between the higher packed bed (120) and the gas-tight liquid collecting and redistributing device (130). The present invention also relates to a method for improving the efficiency of a liquid-gas contacting unit by directing the gas from the lower packed bed to the higher packed bed through the external pipe.
    • 本发明涉及一种液 - 气接触单元(1),该单元包括塔(100),至少一个下部填充床(110)和一个位于其上方的高级填充床(120) 所述塔(100)内的下部填充床(110),设置在所述塔(100)内的所述下部填充床和所述较高填充床(110; 120)之间的气密液体收集和重新分配装置(130) (141)和出口端(142)之间的外部管(140),所述外部管(140)包括入口端(141),出口端(142)和外围壁(143) ; 所述入口端(141)位于所述下填充床(110)和所述气密液体收集和重新分配装置(130)之间,并且所述出口端(142)位于所述高填充床(120)和所述气体 - 致密液体收集和重新分配装置(130)。 本发明还涉及一种通过将来自下部填充床的气体引导通过外部管道到达较高填充床的方法来提高液体 - 气体接触单元的效率的方法。
