System structured packing for a column height reduced distillation.

摘要

A method for operating a rectification column comprising: (A) passing a feed mixture comprising a more volatile component and a less volatile component into a column, said column con- height filler material comprises a plurality of blocks, said blocks having an area density greater than 600 m2 / m3 and less than 1500 m2 / m3 and comprising a plurality of sheets of structured packing oriented vertically having an angle exceeding 45 degrees corrugation and less than 70 degrees, and said bricks have a height less than 15, 24 cm., and Me- us some of said sheets of filler material have a lower region which differs in structure from the remaining region of that sheet so that the resistance to vapor flow in the lower region is less than the resistance to vapor flow in the remaining region; (B) carrying out rectification column in queel steam flows upward through the blocks and liquid flows downward through the block through which the said more volatile component concentrates in the vapor upflowing and said Me- volatile component we concentrate in the liquid flowing down; and (C) withdrawing first fluid from the top of the column, said first fluid having a concentration of more volatile component which exceeds that of the feed mixture, and removing the semi Gundo fluid from the bottom of the column, said second fluid having a concentration of less volatile component which exceeds that of the feed mixture.
