Abstract

The chemical exergy analysis method is based on the second law of thermodynamics. The method is introduced to the study of process design of chemical processes optimization. In this work, chemical exergy is used as a basis to assess reversible reactions. Ammonia synthesis reaction is selected as case study. Chemical exergy analysis is applied to estimate the effect of the process parameters, which are operating pressure and temperature, on the trend of ammonia reaction conversion. The proposed method used for the study is based on Gibbs free energy and the calculation of chemical equilibrium. This study aims to be able to identify the optimal value of process conditions for armnonia production. The main objective of this research is to identify the optimal operating condition that gives the highest armnonia reaction conversion. The finding will provide information to improvement operation performance of an indusnial armnonia production. The exergy analysis result in this research shows that at 500 degree Celsius, which is the typical operating temperature used in indust1ial production, the ammonia yield tends to arise in a very small amount. This is resulting from the minimum reaction driving force or minimum work available for the reaction to take place in the respective temperature
