Abstract
The present disclosure relates to a method and a system for manufacturing an ester-based composition which are characterized in sequentially operating a plurality of batch reactors, and since an ester-based composition is semi-continuously manufactured, the productivity is high and the stability of a batch reactor is secured.
Claims7
A system for manufacturing an ester-based composition, the system comprising:
- a mixer in which a reaction mixture of a polycarboxylic acid and a first alcohol having 3 to 10 alkyl carbon atoms is formed, wherein the mixer comprises a polycarboxylic acid injection path and a first alcohol injection path;
- a reaction unit provided with N number of batch reactors connected in parallel in which an esterification reaction of the reaction mixture is performed, an inlet line for receiving the reaction mixture from the mixer, and an outlet line for discharging reaction products from the N number of batch reactors;
- a supply control unit for controlling the injection amount and the injection path of the reaction mixture such that the reaction mixture is sequentially supplied to the N number of batch reactors from the mixer to allow the reaction to be sequentially completed, wherein the supply control unit is disposed between the mixer and the reaction unit;
- and
- a separation unit for receiving the reaction products through the outlet line of the reaction unit and removing unreacted alcohol therefrom.
