The tbp 750 simulated distillation analyzer can provide accurate data of components ( light oils to residuals ) of crude oils
Tbp 750模擬蒸餾分析儀具有優良的性能，能夠提供原油樣品（從輕組分到渣油組分）的準確數據。To verify the effectiveness of the proposed hybrid fnn, this thesis addressed the estimation problem for the frozen point of light cyclic oil in a fluidized catalytic cracking unit ( fccu ) in a refinery. based on the sample data collected from the industrial unit, we built a soft sensor model by using an above hybrid fnn
最後，針對某煉油廠催化裂化裝置主分餾塔輕柴油凝固點的軟測量估計問題，本文基於工業現場所採集的樣本數據，建立了混合結構神經網路模型，並討論該模型的在線自學習問題，同時與多層前向bp網路、徑向基函數rbf網路模型進行了比較。The azeotropic distillation of the system acetic acid - water - azeotropic agent ( isopropyl acetate and butyl acetate ) is simulated. due to the non - ideal behavior, nrtl - hoc and uniquac - hoc model is used to depict vapor - liquid phase equilibrium behavior of this system. concerning the liquid in the decanter, the stability is checked by tangent plane stability analysis, and the initialization of phase splitting calculation is produced. a good estimate of the phase fration is gotten by successive substitution with newton ' s method, and every component of two phase is gotten by mass equilibrium equation. finally, the solution of this equation is produced with successive substitution calcultion. the naphtali - sandholm method is used to simulation of azeotropic distillation. by virtue of this combined calculation method, the simulation is begun with operational data as basical data. the results of simulation accord with the operating data, which proved that the combined calculation method is credible
該體系具有高度非理想性，氣液相平衡模型採用nrtl - hoc和uniquac - hoc模型，採用切平面判據法對進入分層器中的液相進行液相穩定性測試，提供液液相分離計算的初值，再結合牛頓拉夫森迭代法運算求得相分割系數，根據物料衡算求出各相組成，循環迭代可求得分層各組分數據，共沸精餾模擬計算採用那夫塔列-山德荷姆全變量迭代演算法。
