Ammonia is prodeuced to give a final product named urea which is a very important fertilizer for higher nitrogen content.Several processes has been invented for optimum production of ammonia. Now-a-days, Ammonia production is mainly done by Haber process in which nitrogen andhydrogen react in the presence of an iron catalyst to form ammonia. The hydrogen is formedby reacting natural gas and steam at high temperatures and the nitrogen is supplied from theair. Other gases (such as water and carbon dioxide) are removed from the gas stream andthe nitrogen and hydrogen passed over an iron catalyst at high temperature and pressure toform the ammonia. In our work, simulation of ammonia synthesis process is done on Aspen Hysys 7.1. By using 1.07e+005kmole/hr methane, 2.8e+005kmole/hr hydrogen, 1.02e+005kmole/hr nitrogen, we haveproduced4.6e+004 kmole/hr ammonia.It has also been found that ammonia production increases with the rise of pressure of fresh feed.
