摘　　要：利用Hysys建立某DHX工艺的模拟流程,采用响应面BBD法设计仿真试验方案并完成响应面模型构建,利用所建模型进行工艺参数分析。结果表明,低温分离器温度、膨胀机出口压力及脱乙烷塔底温度间存在较强交互作用;对参数间交互作用起主导作用的参数并不固定,以C3收率为性能指标时低温分离器温度对交互作用起主导作用,以脱乙烷塔热负荷为性能指标时脱乙烷塔底温度对交互作用起主导作用。The simulation process of NGL recovery is established. Box-Behnken design （ BBD ） , one of Response Surface Methodology （RSM）, is used to design the simulation experimental scheme and establish RSM model for corresponding analysis. The results show that there are strong interactions among the temperature of low temperature separator, outlet pressure of the expander and the temperature of the deethanizing column bottom. The main parameters of the interaction are not fixed. The temperature of low temperature separator is the leading parameter of interaction when C3 yield is the performance indicator. In contrast, when the thermal load of deethanizing column is the performance indicator, the temperature of the deethanizing column bottom is the leading parameter.
