摘要
文章从如何自动控制硫磺回收装置的角度介绍了主要存在的自控逻辑应用,包括如何进行顺控点火,如何联锁停炉及正常操作时的自控逻辑应用。文章通过二级CLAUS+还原+吸收的硫磺回收工艺所完成的控制系统逻辑设计及应用,主要侧重于其中的过程控制方案和安全联锁系统方案的设计,以达到装置大型化,长周期运转,提高目的产品回收率,最大限度提高装置的经济效益。
This paper introduces the main application of automatic control logic in the sulfur recovery device from the perspective of automatic control,including how to control ignition,how to interlock the furnace and the application of automatic control logic in normal operation.The logic design and application of the control system through the secondary CLAUS+reduction+absorption sulfur recovery process,mainly focusing on the design of the process control scheme and safety interlocking system scheme.In order to achieve the large-scale device,long cycle operation,improve the recovery rate of the target product,and maximize the economic benef it of the device.
