Liquid ammonia has several industrial uses. Based on the end use, ammonia solutions of varying concentrations are used commercially. There are several methods to liquefy ammonia. However, the most preferred method for liquefying anhydrous ammonia is the use of a two stage, two- cylinder compressor. In this study, we designed a new ammonia compressor based on our examination of compressor designs comprising more than one stage and cylinder. Further, our investigation of the thermodynamic behavior of ammonia at high pressures also influenced our compressor design.
