工业轻烃回收装置的全流程静态仿真模型

为提高轻烃回收 (natural gas liquids recovery,NGL) 装置的产品收率、降低生产能耗,同时确保生产安全、降低装置停车造成的损失,开发了某油田轻烃回收装置的全流程静态仿真模型。基于CAPE OPEN技术,建立流程中的精馏塔等单元,通过模拟计算分析工艺参数,并以现场实际数据为参考进行校正。结合提高乙烷收率的生产要求,评价分析了各工艺参数的影响程度,给出脱甲烷塔的最佳工艺参数。结果表明:该模拟计算结果与实际工艺相吻合,最优工艺参数可应用于指导实际工业生产。

A static simulation model of overall process for the NGL recovery unit

A static simulation model of overall process for a light hydrocarbon recovery plant were developed,which could not only improve the yield,save energy and reduce loss,but could also ensure safety in production.The distillation units were modeled based on CAPE-OPEN technology,the parameters of the process were analyzed by simulation and emendated according to the actual data.The correlative process parameters which could meet the requirement of improving the ethane yield were simulated and evaluated by sensitivity analysis.The process parameters of the demethanizer were optimized.The results showed that the simulation data were in good agreement with the plant data,and the optimum process parameters could be applied to guide the actual industrial production.
