CHEMCAD as a tool when teaching Chemical Engineering. / Chemcad software Modelling

The aim of this project was to design different chemical processes using Chemcad software. Following five Chemcad models that had industrial relevance were designed and discussed, production of nitric acid by ammonia oxidation process, Production of sodium carbonate by Solvay process, production of hydrogen by steam reforming of natural gas, production of sulphuric acid by Contact process and production of sulphur by Claus process. Equilibrium reactor, Gibbs reactor, absorption tower, heat exchangers, condensers, separators, pumps, compressors and mixers are designed on flow sheet diagram using Chemcad software. Mass balances and energy balances of Chemcad models were compared with bachelor thesis work and their differences and similarities were discussed in detail. In all processes reasonable results were obtained. Mostly in all cases results are the same as in the bachelor thesis. It was seen that equilibrium reactors give better results as compare to Gibbs reactors because when conversion factor of the chemical reaction was not known, Gibbs reactor was used and it adjust the conversion by itself according to equilibrium concentrations of the compounds. SI unit system was used in Chemcad models because in Sweden the SI system is very well established.
