摘要:
中和反应是加压法生产硝酸铵装置的关键工序,气氨和稀硝酸精确的流量控制及配比直接影响系统的安全,后续工段的PH值控制效果及设备的使用寿命。该文重点阐述气氨和稀硝酸的流量控制方法、配比调节方案及控制要求,同时介绍了安全生产所必须的联锁控制要求。此控制和联锁方案适用于不同生产能力的加压法硝酸铵装置。
Abstract:
Neutralization reaction is a key process in the production of ammonium nitrate by the pressurized method, and accurate flow control and proportion of gas ammonia & dilute nitric acid directly affect the safety of the system, pH control effect in the subsequent section and service life of equipment. This paper focuses on the flow control method, proportion adjustment and control requirement of gas ammonia & dilute nitric acid, and the interlock control requirement of safety production is also presented. The control and interlock scheme is suitable for pressurized method of ammonium nitrate plant with different production capacity .
