Abstract

To use ammonia for industrial purposes, it should be stored under atmospheric conditions ( 1 atm, -33° C). The equipment necessary for ensuring these conditions includes multi-stage compressors and expansion valves. In this study, the influence of the expansion valves on the expansion of compressed ammonia was investigated, and related calculations were performed by making some assumptions.
