gas fractionator-
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。In order to solve the problems effectively, under the auspices of 863 plan in china, the synthesis diagnosis has been carried by means of measuring and numerical imitating the combustion chamber of refining column, and some conclusions is such as : ( 1 ) through measuring the temperature and combustion in the burning chamber of the refining column, the result shows the temperature difference on the same level is more than that in height direction, and there is a few of co in bottom of burning chamber. ( 2 ) in order to ensure normal work of flue system in lead column in the course of zinc refining, theoretic calculation and measure about the flow resistance of exhaust gas are carried through. the results of study reveal that drawing out force of chimney is inadequate, which is mainly caused by illogicality of flue construction
在研究過程中，採取了現場實測和數值模擬手段對韶關冶煉廠鋅精餾鉛塔燃燒室及排煙系統進行了綜合診斷，具體結果包括如下： （ 1 ）完成鋅精餾鉛塔燃燒室內溫度測試以及燃燒狀況的測試，結果發現：鉛塔燃燒室內水平方向的煙氣溫度並非均勻，而且其溫差比上下方向的溫差更大，以及鉛塔燃燒室尾部存在co未燃燼問題； （ 2 ）為了保證鉛塔煙氣系統的正常工作，對煙道系統的阻力進行了理論計算及測試分析，結果發現：鋅精餾鉛塔煙氣系統中煙囪抽力不夠，這主要是煙道結構不合理所造成的。The development of mass transfer in the system of vapor - liquid - liquid three - phase distillation from trays was introduced, the effects of the hydrodynamic conditions e. g. vapor velocity and ratio of liquid to vapor loading and physical properties of liquid phase, including surface tension, interfacial tension, viscosity or dispersion viscosity, density, relative volatility etc. and the volume ratio of oil to water on mass transfer were discussed systematically, the influence of the second liquid on mass transfer efficiency was also investigated, a gnat deal of viewpoints and suggestions having been put forward in this paper are significant important for optimizing design of distillation tower
