ABSTRACT:
According to the invention, there is provided a method for manufacturing a fluid contacting device according to which a single side wall of vertically continuous hollow prism-shaped elements is formed of a single sheet of metal or like material and a plurality of such sheets are regularly arranged and joined together to form the fluid contacting device. By this arrangement, assembling of the fluid contacting device is made very simple, waste of material in forming the side wall sheet can be held to the minimum and an unused portion between a column and the fluid contacting device can be eliminated whereby a fluid contacting efficiency can be improved.
