Modular Extraction Column

A modular extraction column comprising:

• end blocks respectively having a flange on one side;
• a body block comprising a plurality of column modules stacked on each other, the plurality of column modules being coupled to the flanges of the end blocks in a surface contact manner, each of the plurality of column modules comprising a first module flange and a second module flange provided on opposite ends and an accommodating portion provided in an inner portion to have a predetermined area, wherein the plurality of column modules are coupled to each other such that the first module flange of one column module among the plurality of column modules faces the second module flange of an adjacent column module among the plurality of column modules;
• and
• an inner structure received in the accommodating portions of the plurality of column modules to distribute a fluid,
• wherein the end blocks and the body block communicate with each other, the accommodating portion of each of the plurality of column modules having a quadrangular cross-section in a direction perpendicular to a longitudinal direction thereof.
