Abstract
Official abstract text for this publication.
Provided is a method for stably obtaining a product. The present invention relates to a purification apparatus for purifying a compound, the purification apparatus including: a tank for use in the purification apparatus; and a hydraulic wash column, the tank being at least one of a crystallization tank that forms a slurry containing crystals of a compound or a ripening tank that is capable of keeping crystals of a compound suspended in the ripening tank, the tank including an agitator having an agitator shaft and a bearing, the purification apparatus further including:a line for discharging the slurry containing crystals of a compound from the tank and feeding the slurry to the hydraulic wash column; and a line for flowing between the agitator shaft and the bearing in the tank at least one of a mother liquor derived from the slurry fed to the hydraulic wash column, the slurry containing crystals of a compound, or a melt obtained by melting the crystals.

1 . A purification apparatus for purifying a compound, the purification apparatus comprising: a tank for use in the purification apparatus; and a hydraulic wash column, the tank being at least one of a crystallization tank that forms a slurry containing crystals of a compound or a ripening tank that is capable of keeping crystals of a compound suspended in the ripening tank, the tank comprising an agitator having an agitator shaft and a bearing, the purification apparatus further comprising: a line for discharging the slurry containing crystals of a compound from the tank and feeding the slurry to the hydraulic wash column; and a line for flowing between the agitator shaft and the bearing in the tank at least one of a mother liquor derived from the slurry fed to the hydraulic wash column, the slurry containing crystals of a compound, or a melt obtained by melting the crystals. 2 . A method for producing a compound, the method comprising: feeding a slurry containing crystals of a compound to a tank including an agitator having an agitator shaft and a bearing; discharging the slurry containing crystals of a compound from the tank and feeding the slurry to a hydraulic wash column; and flowing between the agitator shaft and the bearing in the tank at least one of a mother liquor derived from a slurry fed to the hydraulic wash column, the slurry containing crystals of a compound, or a melt obtained by melting the crystals; the tank being at least one of a crystallization tank that forms a slurry containing crystals of a compound or a ripening tank that is capable of keeping crystals of a compound suspended in the ripening tank. 3 . The method for producing a compound according to claim 2 , wherein the compound is a (meth)acrylic acid. 4 . The method for producing a compound according to claim 3 , wherein the (meth)acrylic acid is produced from at least one raw material selected from the group consisting of propane, propylene, acrolein, isobutene, methacrolein, acetic acid, lactic acid, isopropanol, 1,3-propanediol, glycerol, and 3-hydroxypropionic acid. 5 . A method for purifying a compound, the method comprising: feeding a slurry containing crystals of a compound to a tank including an agitator having an agitator shaft and a bearing; discharging the slurry containing crystals of a compound from the tank and feeding the slurry to a hydraulic wash column; and flowing between the agitator shaft and the bearing in the tank at least one of a mother liquor derived from a slurry fed to the hydraulic wash column, the slurry containing crystals of a compound, or a melt obtained by melting the crystals; the tank being at least one of a crystallization tank that forms a slurry containing crystals of a compound or a ripening tank that is capable of keeping crystals of a compound suspended in the ripening tank.
