ASPEN simulation of conversion issues in the HCN conversion reaction process

I used the Gibbs reactor module in ASPEN software for simulation, and the result was that the amount of HCN after the transformation reaction not only did not decrease but actually increased; however, the molar fraction of HCN decreased. I would like to ask for information on the changes of HCN during the transformation reaction.
For any reaction, use Gibbs; all other reactors can be set aside
Are the temperature and pressure values correct? I did some simulations roughly, and it turns out that ammonia is produced at 800°C, with about 95% of the HCN being consumed; of course, the ratio of the raw materials is different from yours. However, the results of Gibbs reactors are often not very accurate. My inlet conditions are H2O, CO, CO2, H2, and HCN, all at 1 kmol/h; after the reaction, the values become 0.258, 2.173, 0.784, 0.784, 0.043, and 0.957 respectively
Thank you for the introduction. I was wondering what method would be the best for simulating the transformation of HCN in conversion reactions?
The ammonia level in the condensate remains high, which exacerbates corrosion in the system; seek solutions
It would be best to explain the detailed manufacturing process and the corrosion conditions
