METHOD AND DEVICE FOR SEPARATING AND RECOVERING SUPERCRITICAL FLUID

摘要

Provided is a method for separating and recovering a supercritical fluid, the method making it possible to reduce maintenance frequency while maintaining a high separation and recovery efficiency. A method for separating and recovering a supercritical fluid including a step 1 for readying a supercritical fluid containing an impurity, a step 2 for changing the fluid into a gaseous state, a step 3 for separating the liquid-state impurity from gaseous-state fluid using a non-adsorption filter (205) having a first mesh size, and a step 4 for using an adsorption filter (216) for further separating the liquid-state impurity from gaseous-state fluid after step 3 using an adsorption filter (216).
