Title:
POLYMER SOLUTION CONCENTRATION METHOD
Document Type and Number:
Japanese Patent JP2016044276
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polymer solution concentration method in which the splash entrainment into the decompression line during the concentration is suppressed and in which the evaporation rate is high.SOLUTION: Provided is a polymer solution concentration method for concentrating a polymer solution in an evaporator 4, and in which, characterized, the evaporator includes a decompression means 24 for decompressing the inside of the evaporator, an atomization means 26 for changing the polymer solution to an atomized body within the evaporator, and a recirculation means 8 for feeding the polymer solution to the atomization means, and the atomized body is atomized in a hollow body shape toward the liquid surface of the polymer solution.SELECTED DRAWING: Figure 1
