Title: 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. Techno-economic analysis (TEA) on SAPO-34 and LTA membrane based technologies was completed. However, compared to the SAPO-34 membranes, LTA zeolite membrane performance both with respect to separation factor and permeance was superior and encouraging. LTA zeolite membranes were selected as the preferred option for comparison with the Combined Electrolysis and Catalyst Exchange (CECE) process for the concentration of tritiated water from dilute HTO-bearing aqueous solutions. It is estimated that the total energy cost to process 10 L/min of tritiated water for the membrane cascade system is substantially lower compared to the CECE process. A preliminary capital cost estimate for the membrane based system and the CECE process is also reported.
