Abstract
A purifying apparatus characterized by being equipped with a vapor dispersing device possessing in a vapor inlet part owned by the apparatus on the lateral inside thereof an opening part facing downward from the horizontal direction and a horizontal projected cross section area in the range of 10-40% of the cross section area of said apparatus. In consequence of the incorporation of the vapor dispersing device according to this invention, the drift of the gas is repressed, the efficiency of separation is improved, and the possible polymerization of a compound under treatment in the lower part of the column is prevented.
Claims12
A purifying apparatus comprising a vapor dispersing device positioned in a vapor inlet part of the purifying apparatus on a lateral inside thereof said vapor dispersing device having at least one opening part facing downward from a horizontal direction and a horizontal projected cross section area of the opening part in a range of 10-40% of a cross section area of said purifying apparatus,
- wherein the purifying apparatus is a plate tower or a packed tower and the distance from the opening part of the vapor dispersing device to a lowermost tray of the plate tower or a packing supporting member of the packed tower is in a range of 1.5-8 times a diameter of the vapor inlet part.
A purifying apparatus having a distillation column and a re-boiler disposed outside the column, said apparatus comprising a vapor outlet nozzle connected from the re-boiler to a column side wall in a gas phase part of a bottom of the distillation column and a vapor dispersing device having an upper part thereof formed as elongated from the part at which the vapor outlet nozzle connects to said column side wall, said vapor dispersing device having an opening part facing downward from a horizontal direction and a horizontal projected cross section area in a range of 10-40% of a cross section area of said apparatus, wherein said vapor dispersing device deflects downwardly vapor introduced from the re-boiler and said distillation column is a plate tower or a packed tower and the distance from the opening part of the vapor dispersing device to a lowermost tray of the plate tower or a packing supporting member of the packed tower is in a range of 1.5-8 times a diameter of a vapor inlet part.
