炼厂氢气系统与轻烃回收系统的集成优化.

Hydrogen, which is one of the necessary utilities in modern refinery, accounts for a relatively high proportion in the cost of oil refining. Saving hydrogen is an important part of daily work to improve the utilization rate of hydrogen. To begin with composition and characteristics of hydrogen system, the optimization strategies and methods were analyzed, and the technical limitations were compared. Due to the relationship between hydrogen system, fuel gas system and light hydrocarbon system, optimization methods for integration of light hydrocarbon recovery system and hydrogen system were put forward. And taking the specific application cases of optimization method for analysis and comparison, it is concluded that optimization method for integration of hydrogen system and light hydrocarbon recovery system is scientific and reasonable, and it is necessary to integrate the light hydrocarbon recovery with it when the optimization for hydrogen resources is carried out.
