Wetted-wall column

Japanese: 濡壁塔 - ぬれかべとう(英語表記)wetted‐wall column
Wetted-wall column
A device that makes a liquid flow down a vertical solid wall and makes a gas flow in the space outside the wall, causing mass transfer or heat transfer between the gas and the liquid, and in some cases heat transfer between the falling liquid and the solid wall (see Figure 1). An industrial example of its use is the production of hydrochloric acid by absorbing synthetic hydrogen chloride gas into flowing water. Hydrogen chloride gas is easily soluble in water, so there is no need to particularly increase the gas-liquid contact area; rather, it is necessary to remove the heat generated during absorption. The heat of absorption can be easily removed by cooling the solid wall.

Japanese:
垂直な固体壁に沿って液体を流下させ,その外側の空間に気体を流し,気体‐液体間に物質移動または熱移動を生じさせ,また場合によっては,流下液‐固体壁間に熱移動を生じさせる装置(図1参照)。工業的に使われる例として,合成塩化水素ガスを流下水に吸収させて塩酸を製造する場合がある。塩化水素ガスは水に易溶性で,気液接触面積をとくに拡大する必要はなく,むしろ吸収時に発生する熱を除去する必要がある。吸収熱は,固体壁を冷却することにより,容易に除去できる。
