SYSTEM FOR CAPTURING SULFUR TRIOXIDE

PROBLEM TO BE SOLVED: To solve such a problem of the conventional technique that a diameter of an absorption column is larger since a porcelain packing material having a planar structure is used, the height of the packed porcelain packing material is higher since the absorption column is used for capturing an acid mist, accordingly, the weight of the packed porcelain packing material and that of the absorption column become heavier since the volume of the packed porcelain packing material is larger and the brick-built absorption column is used and a load of the foundation for the absorption column becomes heavier. SOLUTION: A system for capturing sulfur trioxide can allow the diameter of the absorption column 7 to be reduced since a fluororesin packing material 6 having a linear structure is used, can allow the height of the packed fluororesin packing material to be lowered since a facility for removing the acid mist is used separately for capturing the acid mist of sulfur trioxide, accordingly, can allow the volume of the packed fluororesin packing material to be decreased, can allow the weight of the absorption column to be lessened since a fluororesin lining, which is damaged by the conventional porcelain packing material and thereby is not used, is applied to the absorption column and can allow the load of the foundation to be reduced. As a result, the system for capturing sulfur trioxide, the conventional one of which is larger and heavier, can be made lightweight. COPYRIGHT: (C)2011,JPO&INPIT
