  • Shielding of heat exchangers in columns
    Patent number: 6883788
    Abstract: Disclosed is a method and an apparatus for exchanging heat in a column by passing a first vapor phase through a heat exchanger in the column to exchange heat with a first stream and produce a second vapor phase in the column. The second vapor phase is passed through a shielding device located above the heat exchanger and the shielding device prevents descending liquid from contacting the heat exchanger. The shielding device may be interposed between two heat exchangers in the column.
