Résumé

The hydrogen ortho-para conversion process simulation is one of the key issues of analytical model development of a hydrogen liquefier. Numerous programs like PRO/II, Aspen HYSYS have no dedicated models for hydrogen conversion process simulation. Thereby, it raises the question of ortho-para conversion hydrogen reactors simulation by artificial ways. The object of the work is to consider simulation process ways of the hydrogen ortho-para conversion and to find out an optimal one for realization in process simulators. The study is carried out by the computational-analytical method using simulation programs. Three ways of process simulation are considered. They were compared based on the calculated parameters of each way and analytical outcomes. The results of the work are as follows: optimal hydrogen ortho-para conversion process simulation way was chosen; the simulated hydrogen liquefier (using the optimal conversion simulation way) was compared with the realized cycle with considered all operating losses.
