Abstract
A method for fabricating a distillation column in a remote location away from a permanent manufacturing facility is provided. In one embodiment, the method can include the steps of: forming a plurality of column sections each having a diameter D, each column section comprising a plurality of courses that have been horizontally welded together, wherein each course is comprised of two or more partial shells that have been vertically welded together, wherein each of the two or more partial shells was created by vertically rolling a rectangular plate having a length of at leastwherein N is the number of partial shells used to form the course; installing a distributor and packing in each column section to form a plurality of packed column sections; and stacking the plurality of packed column sections to form a column.
