GAS ABSORPTION COLUMN, METHOD FOR PRODUCING GAS ABSORPTION COLUMN, AND MARINE VESSEL

摘要

Provided is a gas absorption tower capable of preventing damage during an assembly operation thereof, simplifying the assembly operation and improving efficiency thereof. A gas absorption tower (10) for performing gas absorption by bringing a gaseous matter and fluid into contact with each other has: an introducing portion (20) into which the gaseous matter and the fluid are introduced from the outside; an absorbing portion (21) for performing gas absorption by bringing the gaseous matter and the fluid, which are supplied from the introducing portion, into contact with each other; and a discharge portion (24) for discharging the gaseous matter, subjected to the gas absorption, to the outside. The absorbing portion has a cylindrical piping component (11) in which is formed an internal space to which the gaseous matter is supplied, and a spray device (12) for spraying the fluid to the gaseous matter in the internal space. The cylindrical piping component is divided into a plurality of parts in the central axis direction thereof. The cylindrical piping component includes a lower cylinder (31) and an upper cylinder (32) that configure a cylinder when assembled. The lower cylinder (31) and the upper cylinder (32) are each formed to have a shape obtained by cutting a cylindrical body along the central axis direction thereof.
