PROBLEM TO BE SOLVED: To provide a multitubular regenerator of a simple structure capable of efficiently taking out the concentrated absorption liquid. SOLUTION: In this multitubular regenerator, an upper gas-liquid tank 2 and a lower solution tank 3 are connected by means of a plurality of heat transfer tubes 4<SB>1</SB>, 4<SB>2</SB>, 4<SB>3</SB>in a state of being communicated with each other inside, the gas-liquid tank 2 is partitioned into a plurality of gas-liquid tank sectors 2<SB>1</SB>, 2<SB>2</SB>by an upper partitioning member 5, the solution tank 3 is partitioned into a plurality of solution tank sectors 3<SB>1</SB>, 3<SB>2</SB>by a lower partitioning member 9, and a communication passage 10 is constituted in a state of successively passing through each of heat conductive tubes 4<SB>1</SB>, 4<SB>2</SB>, 4<SB>3</SB>successively through each of gas-liquid tank sectors 2<SB>1</SB>, 2<SB>2</SB>and each of the solution tank sectors 3<SB>1</SB>, 3<SB>2</SB>. One of the solution tank sectors 31, 3<SB>2</SB>is positioned at an upstream end of the communication passage 10, and the solution tank sector 3<SB>1</SB>of the upstream end is provided with a solution inlet 11. One of the gas-liquid tank sectors 2<SB>1</SB>, 2<SB>2</SB>is positioned at a downstream end of the communication passage 10, and the gas-liquid tank sectors 2<SB>2</SB>of the downstream end is provided with a solution outlet 12. Further an upper end part of the upper partioning member 4 has a ventilation hole 6 to use an upper layer gas phase-space of the gas-liquid tank sectors 2<SB>1</SB>, 2<SB>2</SB>as a common space, and an exhaust port 8 is formed at the common space 7.
