由于压缩机混合气中氢气组分变化偏离设计值，致使柴油加氢循环氢离心机组原设计防喘振曲线不能满足生产的需要，导致机组运行中采用防喘振阀门回流的方法维持生产，负荷较高大部分循环气处于自循环状态，且无法保证反应系统所需氢气。压缩机处于高负荷下运行，使得汽轮机负载高，造成不必要的损失。对此具体分析了其原因，通过实测喘振点，修正了由于气体组分发生变化的防喘振曲线，解决了加氢装置运行的瓶颈，为用户实现有效氢量增加25%，直接节约动力成本260万/年。

Due to the hydrogen gas component changing in the compressor mixture deviates from the design values, it had caused the original design anti-surge curve of diesel hydrogenation recycle hydrogen centrifugal compressor unit cannot meet the requirement of production, and the means of adopting anti-surge valve reflux will be used to maintain production in the unit operating. The load was higher, most of circulating gas was in the state of self-circulation, and the required hydrogen gas in reaction system cannot be ensured. The compressor will be running with high load, which made the turbine with high load and caused unnecessary losses. This paper had analyzed the reason, and based on actual measuring surge points, corrected the anti-surge curve caused by the change of gas component. Then the problem in hydrogenation unit running was solved, which increased 25% of effective hydrogen and saving power costs 2.6 million per year directly for users.
