Development of CA-Storage System with Gas Separation Membrane (Part 1)

Apparatus and its Performance

Abstract

A modified gaseous components system for CA-storage using a gas separation membrane was designed, constructed and tested. The membrane has permeability of CO₂, O₂ and N₂ in order. The distinctive feature of this system is the introduction of a gas circuit selecting concept with a set of membrane module to get a desired modified gaseous components. It was effective in decreasing CO₂ content and increasing O₂ content, but operation of N₂ introduction to the chamber was left as future study. The method of controlling gaseous components in the chamber was shown.
