In order to improve the reliability of the urea ammonia production equipment in Heze Company,combined with the actual situation on site,this study focuses on the poor automatic adjustment of ammonia supply in the urea station and the irregular fluctuations in the required ammonia supply of each unit,resulting in high NOx regulation pressure of the main engine and non-compliance with environmental emissions standards.The reliability of the new process is studied from the basic links including feed and steam logic control,on-site signals including dissolution tank liquid level signal,ammonia supply pressure,etc.
