Abstract:

The purpose of this effort was to assess the feasibility of developing a desiccant system to produce potable water from atmospheric sources that is compatible with military constraints. Goals were 1 to examine desiccant technology, investigate methods of using available desiccants to collect atmospheric moisture, 2 develop a conceptual model of a desiccant water production system, and 3 develop a mathematical model to simulate the operation of the conceptual model. Results show that a desiccant system can produce large quantities of potable water using relatively small amounts of fuel for heat and fan power. The focus of this project was using a liquid desiccant such as triethylene glycol in an absorption-distillation cycle. This report documents the theoretical analysis of a hypothetical liquid desiccant based system for producing liquid water through collection of atmospheric moisture. Estimates are mode of cost, weight and water production rate for the hypothetical system.
