Patent ID: 7303682

Claim:
A fluid collecting device for collecting fluid from a column comprising: a second fluid conveying system ( 11 ) for delivering a fluid flow from a plurality of collecting points ( 10 ); and a collecting plate ( 9 ) divided into a plurality of sections ( 15 ; 16 ), wherein each section conveys the fluid to at least one collecting point ( 10 ), wherein each section of the collecting plate comprises a plurality of collecting channels ( 13 ; 13 b ) for collecting partial fluid flows from the column into a second fluid transfer port ( 12 ) for conveying fluid flow to the collecting point ( 10 ), wherein the hydraulic lengths from points where the partial fluid flows from the column to the collecting point ( 10 ) vary, and second means ( 14 ) for controlling the partial fluid flows by differential pressure, wherein the second means ( 14 ) for controlling the partial fluid flows is disposed between collecting channels ( 13 ; 13 b ) and the transfer port ( 12 ).
