Techno-economic Analysis of Advanced Zeolite Membranes for the Concentration of Tritiated Water

Abstract

This report describes the techno-economic analysis of advanced molecular sieve zeolite membranes to separate and concentrate tritiated water (HTO) from dilute HTO-bearing aqueous streams. In the first phase of this effort, several monovalent and divalent cation-exchanged silicoalumino phosphate (SAPO-34) molecular sieve zeolite membranes were synthesized on disk supports and characterized with gas and vapor permeation measurements. In the second phase, Linde Type A (LTA) zeolite membranes were synthesized on disk and tubular supports. The pervaporation process performance was evaluated for the separation and concentration of tritiated water.
