Disclosed is a double-wall gas-liquid device which avoids limitation of installation space or increase of installation costs caused by extra columns or recirculation facilities, and can extend capacity of the device to be applied when using a raw material which generates much foam. The present invention performs the first separation by spreading the raw material to an external housing and inputting gas, performs the second separation by transporting the same to an internal housing, and treats the raw material twice through a double-wall structure, thereby maximizing separation effect. Also, through the double-wall gas-liquid device, limitation of installation space and increase of installation costs when installing two columns respectively can be solved. |
