Zusammenfassung:	The present invention is directed to a method of heating a light ends column through directing one or more vapor side streams from a drying column to the light ends column. The present invention is also directed to a carbonylation process for producing acetic acid, wherein one or more vapor streams from a drying column provide the external energy required to drive separation in the light ends column.
