    Abstract: A neutralization/water separation tank for an esterified product including: a neutralization part in which a crude product mixture containing alcohol and an ester compound, a neutralizing agent, and water are put to produce a neutralized mixture; a water separation part which divides the neutralized mixture into a floating layer and an aqueous layer; a first partition wall which extends upward from a bottom surface to provide an upper passage and by which the neutralization part and the water separation part are partitioned; and a second partition wall which extends downward from a ceiling to provide a lower passage, wherein the water separation part includes: a first water separation part into which the neutralized mixture is introduced from the neutralization part through the upper passage; and a second water separation part into which the neutralized mixture is introduced from the first water separation part through the lower passage, wherein the first water separation part and the second water separation part are partitioned by the second partition wall.

    Abstract: The present disclosure relates to a diester-based material production unit including a reaction device in which an esterification reaction of dicarboxylic acid and a primary alcohol is performed, a column in which the gas-liquid separation of the primary alcohol and the water introduced is performed, a heat exchanger installed on a gas phase line of the column to remove heat of the gas phase line, a flash drum in which separation of a liquid phase and a gas phase is performed in the mixture stream including the primary alcohol and the water, a condenser installed on the flash drum upper line, and a layer separator in which the layer separation of a mixture of a liquefied primary alcohol and water into an organic layer and an aqueous layer is performed, wherein one or more lines through which recirculated primary alcohol from the flash drum and the layer separator flows are connected to an upper portion of the column. According to the present invention, a coolant usage amount can be reduced and a rheological problem can be eliminated since a liquid phase and a gas phase coexist in a pipe.

    Abstract: A neutralization/water separation device for an esterified product including: a neutralization tank in which a crude product mixture containing alcohol and an ester compound, a neutralizing agent, and water are put to produce a neutralized mixture; a water separation tank disposed below the neutralization tank to divide the neutralization mixture into a floating layer and an aqueous layer; a partition wall extending downward from a ceiling of the water separation tank to provide a lower passage in the water separation tank; and a transfer line that transfers the neutralized mixture from the neutralization tank to the water separation tank, where the water separation tank includes: a first water separation part into which the neutralized mixture is introduced from the neutralization tank through the transfer line; and a second water separation part into which the neutralized mixture is introduced from the first water separation part through the lower passage, where the first water separation part and the second water separation part are partitioned by the partition wall.
