基于HAZOP的大型氨制冷系统风险评估方法
|
Abstract:
本文以液氨制冷系统作为1个节点进行分析，以气液分离器B1压力过高导致压缩机S1-S5排气管道PT-ZD001压力过高为例，详细描述了HAZOP分析过程，提出建议确认压缩机启停逻辑关系，确保个别压缩机故障时，其他压缩机可以正常启动运行。
This paper takes the liquid ammonia refrigeration system as single node for analysis, considering the high pressure of the gas-liquid separator B1 resulting in the high pressure of the discharge pipe PT-ZD001 of compressor S1-S5 as an example. The HAZOP analysis process is described in detail, and the compressor start-stop logic is suggested to be confirmed in order to ensure that other compressors can start and run normally when individual compressors fail.
