PROBLEM TO BE SOLVED: To provide an air separation plant eliminating capital expenditure required in relation to a custom design or structure of constituted elements for manufacturing an air separation plant, by a structure with the constitutional elements manufactured by an assembling method. SOLUTION: An air separation plant 1 includes a heat exchanger 18 and a distillation column section 20, both of which are manufactured by an assembling method. The heat exchanger 18 is able to be used in an air inflation plant, a waste inflation plant, and a product inflation plant by simply being connected with appropriate pipes. An air separation unit comprises standardized sections by using structuralization filling appropriately. A simplified liquid- distributing apparatus and its supporting body are used so as to be able to distribute liquid into the filling and support the filling in the column. |
