摘要
为保证正丁烷装置能够在线操作、生产出合格的产品、保持装置操作和维护的安全、避免大的灾难性故障,设计了一套三重化冗余安全联锁系统。重点介绍了联锁系统在正丁烷装置中的应用、安全系统的常用指标、安全联锁系统的总体硬件方案,以及循环氢/新氢压缩机、加氢进料泵和电加热炉的联锁自保系统。各个联锁自保系统的设计对确保正丁烷装置稳定、安全地运行具有重大的意义。
To keep online operation of N-butane unit and produce qualified products, as well as guarantee the security of the unit in operation and maintenance and avoid catastrophic faihtre, the triple redundant safety interlock system has been designed. The application of interlock system in Nbutane unit, the commonly used indexes of the safety system, the overall hardware scheme of the safety interlock system, the interlock and self-protection system for recycle/fresh hydrogen compressor, hydrogenation feed pump and electric heating furnace are introduced emphatically. In order to ensure the plant operates stably and safely, the design of each interlock and self-protection system possesses great significance.
