| The binary interaction parameters of the rectisol system were redetermined via the modified peng-robinson equat ion in this paper, and the mathematical models which can be used to describe exactly the thermodynamic properties of the five columns in the rectisol system designed by LINDE were set up through the Sum-Rates and Bobble-Dew Methods ,and the calculation and comparison were made .Though the calculation It was proved that the model can he used at various conditions (one-stage and multi-stage , high temperature and low temperature, high pressure and low pressure ).Compared with the design some faults were found, and some suggestions were provided.In conclusion. This paper will take use for the home-made and design of the large synthetic ammonia plant. |
