| description | The purity of hydrogen finally purified in the hydrogen purification process system is greatly influenced by the uniformity of the purification temperature of the dry tower. An in-house code that can be easily used by field designers has been developed to predict the capacity of the appropriate heat source and the time to reach the temperature of the dry tower. A code was developed to predict unsteady heat transfer using VBA. To verify the developed code, a grid independence test was performed, and finally, calculations were performed for two cases. The factor that influences the temperature history over time is the precise determination of values for the density, specific heat, and thermal conductivity of the heterogeneous materials composing the dryer tower. It was confirmed that the developed code well describes the actual test trend data of the regeneration process of adsorption and desorption, and it is judged that the code developed in the design process of various capacity systems will be effectively applied to the heat capacity calculation in the future. |
