| Abstract: | In view of the complexity of ammonia synthesis, a two-step gradual optimization experiment for increasing the net value of ammonia was designed. As the advance preparation for the experiment, we finished tuning parameters of PID controllers that were used in synthetic ammonia unit. Then a predictive control system was designed. After the system was put into operation, automatic control of hot-point temperature of ammonia reactor was achieved, and operation performance of ammonia reactor was improved. At last a two-step gradual optimization experiment was done to optimize the operation condition of the ammonia synthesizer (80,000 tons per year). Net value of ammonia has risen 0.52%, promising a considerable economic benefit. |
