Title:
CONTINUOUS REFINING SYSTEM FOR ESTERIFICATION REACTION PRODUCTS
Document Type and Number:
WIPO Patent Application WO/2020/204562
Kind Code:
A1
Abstract:
The present invention relates to a continuous refining system for esterification reaction products, and a continuous refining method which is for esterification reaction products and can be performed via the continuous refining system. The continuous refining system comprises a neutralizer, a distiller, and a product refiner. The inner space of the neutralizer is divided in the left-right direction into a neutralizing space and a layer separating space, and is provided with at least one partition wall so that a path connecting the two spaces is formed, wherein the path starts from the upper portion of the neutralizing space. The present invention can reduce the amount of low grade alcoholic waste water generated during refinement, while enabling an efficient continuous refining process.
