Abstract

An ammonia converter is a place where an ammonia formation reaction takes place which is strongly influenced by several factors such as temperature. The higher the temperature, the greater the conversion, but this reaction is exothermic. A further increase in temperature will cause the reaction to shift to the reactants. For this reason, a cooling process is carried out at the inlet temperature of each bed. This study aims to determine the magnitude of the resulting conversion and the effect of the ammonia converter temperature using Aspen Hysys V10. Based on the research, the factory design data showed that N2 was converted to NH3 by 28.29%. While the actual data on December 10, 2021, is the highest conversion result with an N2 conversion of 24.46%. Judging from these data, the production of NH3 in the actual data has decreased compared to the design data. %Mole of NH3 outlet in the design data is 16.46%, Mol, while the actual data on 10 and 15 December 2021 is 11.28%, Mol. The highest ammonia product was produced at an inlet temperature of 384oC and the resulting product was 3917.7 kg/day.
