Desublimer for the recovery of sublimed products, particularly phtalic anhydride, from reaction gases

摘要

Desublimer for the recovery of sublimed products from reaction gases, consisting of a closed housing for the passage of the reaction gas and a plurality of horizontally mounted rows of finned tubes for the passage of the heating or cooling medium, in which a perforated slider is mounted on each finned tube to allow adjacent finned tubes to bear loosely against each other, the stack of superposed sliders associated with each finned tube being loosely supported on a girder securely attached to the housing.
