摘　　要：四丁基溴化铵(TBAB)可以作为热力学促进剂用于从烟道气中分离CO_2。研究CO_2-N2-TBAB-H_2O体系水合物生成条件的热力学模型,为水合分离CO_2提供热力学相平衡数据,具有一定实际意义。将Chen-Guo水合物热力学模型用于计算CO_2+N2在TBAB溶液中的水合物生成压力,将计算结果与实验值、文献值进行比较,误差分别为15.96%、5.45%,并对误差进行分析。Tctra-n-butyl ammonium bromide （TBAB.） is used as thermodynamic promoter in separat ion CO 2 from flue gas.Thcrmodynamicmodcl is investigated for hydrate formation condition of CO2 -N2 -, TBAB -H2Osy stem , which can pro vide thermodynamic phase equilibrium data for hydrate separation of CO 2 and has cer tain significa nce. In thermodynamic hydrate model is used to calculate hydrate formation pressure of CO 2 ＋N 2 in TBAB solution . The ca lcu la tio nresult is compared with experimental value and literature value. The deviation is 15.96% and 5.45% and the deviation isanalyzed.
