【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 k Pa)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 the actual operation of the refinery, the change of the properties of the feedstock treated by the hydrogenation unit and the adjustment of the production load will lead to the change of the hydrogen consumption of the hydrogenation unit. The optimization model of fixed structure hydrogen network with intermediate pipeline network is constructed. The model includes hydrogen supply unit, hydrogen utility network / intermediate pipe network, compressor, hydrogenation unit, fuel system and their fixed connections. By introducing 1600 psi (1 psi=6.895 k Pa) intermediate pipeline network into the conventional hydrogen network, the new hydrogen spare compressor of a hydrogenation unit can be reduced. The design stage can reduce the investment of one compressor, that is, the optimal configuration of the new hydrogen compressor can be realized. According to the normal / high / low load condition of hydrogenation unit, the hydrogen network with intermediate pipe network is optimized, and the flow distribution of flow unit and the starting and stopping strategy of compressor under different working conditions are obtained, and the operation optimization of multi-condition hydrogen network is realized.
