A PROCESS AND A COLUMN FOR EFFECTING MASS TRANSFER AND A METHOD OF RETROFITTING A COLUMN FOR EFFECTING THE MASS TRANSFER

摘要

The present invention relates to a process and a column for effecting mass transfer between a liquid phase and a gaseous phase within a filled-type column which comprises an external shell accommodating at least one filler-containing basket wherethrough said phases are caused to flow in a countercurrent relationship, characterized in that it comprises the step of feeding said gaseous phase to said at least one basket through a gas- permeable basket surface which is larger than the basket cross-section. The present invention also relates to a method of retrofitting a column for effecting the mass transfer.
