Dynamic Simulation of Ammonia Synthesis Loop under Abnormal Conditions

Abstract:

As the core component of synthetic ammonia process, ammonia synthesis takes place in a loop in which hydrogen and nitrogen are converted to ammonia per pass through the ammonia converter. Its nonlinear mathematic model is built in this paper, based on partial data from literatures. The research focus on four types of unit: synthesis converter, ammonia separator, synthesis gas compressor and ammonia chiller, and dynamic simulation under fault conditions is carried out. Results show that the model has enough precision to meet fault simulation requirements. This work establishes the research foundation for future quantitative fault modeling, diagnosis algorithm selection and fault effect analysis.
