TRANSPORTABLE PACKAGE WITH A COLD BOX, AND METHOD FOR PRODUCING A LOW-TEMPERATURE AIR SEPARATION SYSTEM

摘要

The invention relates to a transportable package with a cold box, in the interior of which at least one double column of a low-temperature air separation system is arranged, i.e., a double column having a high-pressure column and a low-pressure column. The high-pressure and low-pressure columns contain mass transferring elements. The mass transferring elements in at least one sub-region of the low-pressure columns are formed by an ordered packing made of folded metal sheets having a thickness of 0.2 mm or less. The ordered packing has a specified surface area of at least 1000 m2/m3. At least in a sub-region of the high-pressure column, the mass transferring elements are formed by rectifying plates arranged one over the other and which have a clearance of less than 195 mm. The invention further relates to a method for producing a low-temperature air separation system using such a transportable package.

主权项

1. A transportable package with a cold box (51), in the interior of which a double column of a low-temperature air separation system is arranged which has a high-pressure column (3) and a low-pressure column (5) which are arranged one above the other, wherein the high-pressure column (3) and the low-pressure column (5) contain mass transfer elements, and the mass transfer elements are formed in at least one subregion (A, B, C, D, E) of the low-pressure column (5) by an ordered packing which is made of folded metal sheets, characterized in that
the metal sheets have a sheet thickness of 0.2 mm or less, in that the ordered packing has a specific surface area of at least 1000 m2/m3 and in that at least in a subregion of the high-pressure column (3), the mass transfer elements are formed by rectification plates arranged one above the other which have a plate spacing of less than 195 mm, in particular less than 180 mm.
