Engineering Design and Cost Analysis of Chlorine Storage Concepts for a Zinc-Chlorine Load-Leveling Battery.

摘要

This project evaluated and compared alternate chlorine storage approaches in terms of the key technical,safety,economic,and environmental aspects. The study has demonstrated for an ambient pressure zinc-chloride battery that the chlorine hydrate approach is a simpler and less expensive storage system than liquid chlorine. Absorption of chlorine in carbon tetrachloride was ruled out because adequate energy efficiencies could not be obtained for the battery system using this chlorine-storage concept. An analysis of the chlorine storage systems studied indicates that safety hazards are moderate and that no extraordinary hazards exist. In addition,the various chlorine storage approaches studied appear to be in compliance with existing environmental regulations.
