Abstract: Provided is a packed column capable of achieving sufficiently high distillation performance even with the height of its gas-liquid contactors reduced. The packed column is a packed column which includes a gas-liquid contactor 17, 18 inside a tubular body 16 and a liquid distributor 19 in the upper most portion and causes descending liquid and ascending gas to contact each other in the gas-liquid contactor. The operation pressure is in the range of 200 to 1500 kPaG. The relative volatility is in the range of 1.9 to 3.1. The gas-liquid contactor is vertically divided into at least two parts. A gas disperser 20 is provided at at least one position between a lower one of the gas-liquid contactors and an upper one of the gas-liquid contactors, the gas disperser uniformly dispersing the composition of the ascending gas rising from the lower gas-liquid contactor toward the upper gas-liquid contactor.
