This study assesses global efforts to enhance existing ammonia plants and explores the feasibility of integrating heat exchangers at different stages of ammonia production. Based on this, the researchers analyzed two heat exchange systems, namely the NH3-H2 shell and tube heat exchanger and the H2O-to-H2O helical heat exchanger, in order to investigate their objectives. This study investigated the use of different NH3-H2 compositions as working fluids in shell and tube heat exchangers, specifically focusing on the shell and tube heat exchanger. The ASPEN HYSYS software was utilized for this analysis. This investigation conducted a comprehensive analysis of different sensitivity analyses to assess the influence of ammonia efficiency on the cooling process. The utilization of shell and tube heat exchangers in cooling applications, specifically those with high ammonia concentrations, can result in a more compact design for the heat exchanger. The observed outcome can be explained by the advantageous characteristics of ammonia, such as its higher heat capacity and improved heat transport properties compared to water. Furthermore, the study utilized a computational fluid dynamics (CFD) approach, specifically employing ANSYS Fluent for the analysis. The helical design of the heat exchanger efficiently distributes heat flux under specific conditions. The heat flow decreases gradually along the length of the exchanger due to this distribution.
