摘　　要：以相似理论为基础,分析并确定氨合成气压缩机组在氮气循环开车时的关键技术参数;运用相似模化设计法,并综合考虑离心压缩机防共振、喘振和超温的技术要求,计算得到氨合成气压缩机组氮气循环开车时的工艺参数;采用化工计算软件进行模拟计算和方案优化。经氨合成装置开车运行验证,表明所确定的开车方案满足生产需要。Basing on the similarity theory,the synthesis gas compressor set＇s technical parameters in nitrogen circulating operation were analyzed and determined; through employing the similarity modeling method and having technical requirements of protecting the centrifugal compressor from resonance and surge and over-temperature considered,the synthesis gas compressor set＇s process parameters were calculated,simulated and optimized with the chemical calculation software. The results demonstrate that the operation scheme verified in the operation can fully meet the production needs.
