- 摘要:
- 为研究天然气乙烷回收装置的工艺操作优化,通过建立工艺模型,分析了天然气原料系统变化对于装置各项操作指标的影响,并研究了蒸馏压力、回流、冷却温度等操作参数对于液泛、产率、经济效益、能耗等的影响与量化关系。分析发现,随着原料性质与供气压力的变化,可通过及时调整天然气乙烷回收装置操作参数,使其实现稳定操作,进而优化装置的约束条件与经济指标,达到操作优化的目标。通过分析优化潜力,验证了开发产量、效益和能耗实时优化与控制的必要性与可行性,为后续优化控制系统的实施打下了良好基础。
This study focuses on the process operation optimization of Natural Gas Ethane Recovery Units. Through the development of a process model, we analyzed the impact of variations in the natural gas feed system parameters on various operational indicators of the unit. The study investigated the quantitative relationships between operating parameters such as distillation pressure, reflux, and cooling temperature, and their effects on flooding, yield, economic benefits, and energy consumption. Analysis revealed that as the feed gas properties and gas supply pressure change, timely adjustments to the operating parameters of the Natural Gas Ethane Recovery Unit can achieve stable operation, thereby optimizing the unit's limitations and economic indicators to meet optimization goals. By examining potential optimization effects and opportunities, we verified the necessity and feasibility of realtime optimization and control of production yield, economic efficiency, and energy consumption. This study lays a solid foundation for the subsequent implementation of an control system optimization in Natural Gas Ethane Recovery Units.
