Method and apparatus for manufacturing silica aerogel blanket

Abstract

An apparatus for manufacturing a silica aerogel blanket. The apparatus includes a supercritical extractor into which a silica hydrogel is introduced and CO2 is injected; a separator connected to the supercritical extractor through a pipe and configured to separate an extract discharged from the supercritical extractor into a gaseous phase comprising CO2 and a liquid phase comprising a solvent to discharge the gaseous phase and the liquid phase; and a condenser connected to the separator through a pipe and configured to condense the gaseous phase comprising CO2 discharged from the separator, wherein the separator is operated under the condition of a pressure of 60 bar to 90 bar, and the condenser condenses the gaseous phase comprising CO2 discharged from the separator so that the gaseous phase has a temperature of 10° C. or higher and a pressure of 60 bar to 90 bar.
