<p>PURPOSE:To obtain the title evaporator, which can surely treat noncondensing gas, efficiently gather a required compound and operate stably, in an evaporator, to the side of which fluid of condensation side including the noncondensing gas is charged. CONSTITUTION:On the outlet side of a fluid of condensation side in a condensor 20 for crude argon, a gas-liquid separator 21 or the vent pipe 42 is provided, and a discharge pipe 23 for discharging condensable fluid with multicomponents from a gaseous layer separated in the gas-liquid separator 21 is also provided. The discharge pipe 23 or the vent pipe 42 is connected to a product-gathering circuit.</p> |
