| 摘 要： | 炼油厂在实际运行过程中,加氢装置处理的原料油性质发生变化以及生产负荷调整,都会导致加氢单元耗氢量的变化。构建了具有中间管网的定结构氢网络优化模型,该模型包括供氢单元、氢气公用工程管网/中间管网、压缩机、加氢单元、燃料系统以及它们之间的固定连接关系。在常规氢网络中引入压力为1600 psi（1 psi=6.895 kPa）的中间管网,可以减少一台加氢装置的新氢备用压缩机,设计阶段可少投资一台压缩机,即实现了新氢压缩机的优化配置。针对加氢单元正常/高/低负荷3种工况,对具有中间管网的氢网络进行了优化,得到了不同工况下流股的流量分配和压缩机的启停策略,从而实现多工况氢网络的运行优化。

| Abstract: | In actual refinery operations, change of feedstock properties and adjustment of production load often lead to change of hydrogen consumption in hydrogenation units. An optimization model was proposed for hydrogen network with fixed structure and intermediate headers, which was consisted of hydrogen supply units, hydrogen utility headers, intermediate headers, compressors, hydrogenation units, fuel system, and established interconnections. Adding an intermediate header with pressure of 1600 psi into conventional hydrogen network could eliminate one standby backup compressor for hydrogenation unit, which capital cost of the backup compressor was saved during design stage and compressor deployment was optimized. Optimization of the hydrogen system with an intermediate header yielded flowrate distribution of different streams and start-stop strategy of compressors under three scenarios of normal, high, and low production loads of hydrogenation unit, which achieved targets of operation optimization for multi-scenario hydrogen network. |
