"Trays are shown for columns, but alternatively packing can be used. Multiple feeds and side streams are often used and may be added to the symbol. Details of examples may be found in Kirk-Othmer Encyclopedia of Chemical Technology, 5th ed., John Wiley & Sons, New York (2004-2007). Industrial Example Recovery of phthalic anhydride from non-condensible gas Extraction of sucrose from sugar beets with hot water Recovery of detergents from waste solutions
