Abstract

A semiempirical mathematical model for the industrial ammonia oxidation process has been derived. The model takes also the ageing of the catalyst into account. The model is used to simulate the behaviour of the plant and the results show a good conformity with the operational experiences and published qualitative results.

Based on this model an examplewise optimization study of the whole nitric acid plant has been carried out. The objective function used is the total variable costs minus total revenue value of production integrated over one service period of the catalyst.

This minimization problem can be solved by using dynamic programming and preliminary numerical calculations give about 2% better result than the conventional strategy in plant operation.
