丁二烯抽提(GPB)装置的第一、二萃取精馏塔底部均装有侧沸器,实际上是集液板。与一般塔板不同,模拟计算时不能简单地采用三对角矩阵法求解所列方程组,而必须用矩阵求逆法或其它方法求解,这就需要更多的内存和更多的计算时间。文中将数学模型进行变换,使之仍可采用三对角矩阵法求解。在此基础上,应用了二阶Runge-Kutta及三对角矩阵联合法计算,顺利收敛,达到满意的计算精度。

Saturates(S), olefines(O) and aromatics(A) in gasoline up to a boiling point of 200℃ can be determined quickly in one run by GC based on a research for a high-performance reversible olefine trap. This analytical system is equipped with two columns and a column switching valve. The flow scheme is illustrated in Fig. 1. The sample at first passes into a polar CEF column (COL. 1) in which saturates and olefines are eluted while aromatics is retained. Olefines and saturates pass through an AD-l...

Saturates(S), olefines(O) and aromatics(A) in gasoline up to a boiling point of 200℃ can be determined quickly in one run by GC based on a research for a high-performance reversible olefine trap. This analytical system is equipped with two columns and a column switching valve. The flow scheme is illustrated in Fig. 1. The sample at first passes into a polar CEF column (COL. 1) in which saturates and olefines are eluted while aromatics is retained. Olefines and saturates pass through an AD-l column (COL. 2) where olefines are adsorbed at lower temperature (80℃), and saturates are detected as a single peak. Then the valve is switched to backflush the aromatics. After all of the aromatics are eluted from the polar CEF column, the valve is switched back to its original position and the AD-1 column is heated up to 200℃. Olefines are then eluted as a single peak. The total-analysis time is less than 30 min. Fig. 2 is a typical chromatogram for such analysis. Due to the fact that AD-1 adsorbent has high thermostability, adsorptive power and desorption efficiency(>98%), both accuracy and reproducibility are good enough for the routine analysis. Under the operating conditions the lifetime of AD-1 column can reach 400 sample injections.

在研制成功高效烯烃可逆吸附剂AD-1的基础上,开发了一套适于日常分析的高稳定性专用SOA分析系统和相应的分析方法。分析样品时,样品先进入极性分析柱(COL.1),芳烃留在柱中,烯烃与烷烃继续进入可逆吸附柱(COL.2)。烯烃被吸附,烷烃进入检测器,待饱和烃全部流出后,切换十通阀反吹芳烃,待芳烃完全流出后再将十通阀切换回进样状态,同时将吸附柱升温至200℃,使烯烃脱附出来,利用积分仪以面积归一法计算出样品中的饱和烃(S)、芳烃(A)及烯烃(O)的含量。至此完成一次样品分析。

The MESH equation system of one-column distillation process for benzene-toluene was established. With computer iteration calculation method, the distributions of gas flow, liquid flow, temperature, concentration on each theoritical bed and the heat loads on the top and bottom of tower were obtained. The calculated thermodynamic efficiency for one-column distillation process is 13.97%. Based on the simulation results, a binary distillation column was proposed in this paper, an analysis for the process was performed and the correlation variables between the two towers, the top flow rate from the high pressure tower and its reflux, were determined. Under the conditions that the tower pressure and bottom flow rate from the high pressure tower were given, taking comprehensive benefit as optimizing object, reflux ratio between two columns as decision variable, the optimization calculation was performed with one-dimension fixed step search method and the operating conditions for the binary distillation column were determined. The optimization results show that compared with the one-column distillation process, the binary distillation column with the operating pressure 34.34 N/cm 2 and reflux 1.1 in high pressure tower and mormal pressure and reflux ration 3.2 in low pressure tower can save energy by 32%,save steam consumption by 28%, increase thermodynamic efficiency by 4.39%. The binary distillation column has been confirmed to be an effective energy saving one.
