PURPOSE:To provide a compact fractionating tower in which a uniform flowing velocity distribution is formed and vapor-liquid contact in a filler is preferably conducted by providing a second filler having larger pressure loss than that of the first filler at the upstream side of the gas flowing part of the first filler in a charge type fractionating tower. CONSTITUTION:In order to prevent gas drift in a crude argon tower 35, second filler 41 having large pressure loss is provided so as to make gas flowing velocity uniform at the upstream of a first filler 40, thereby efficiently bringing vapor-liquid contact in the filler 40.
