1. A multi-bubbling region column tray, comprising:
at least two bubbling regions provided with first openings for liquid and gas to be mixed; and
at least one non-side downcomer that comprises at least one hanging downcomer, wherein:
the at least one hanging downcomer includes one or more second openings and one or more third openings, the one or more second openings configured to allow liquid to flow toward a first bubbling region located at a first lower side of the at least one hanging downcomer, the one or more third openings configured to allow liquid to flow toward a second bubbling region located at a second lower side of the at least one hanging downcomer;
the at least one hanging downcomer is configured to separate the liquid that flows out from the one or more second openings and the liquid that flows out from the one or more third openings; and
a ratio of an area occupied by the one or more second openings to an area occupied by the one or more third openings is substantially similar to a ratio of a gas channel area of the first bubbling region to a gas channel area of the second bubbling region.
