| These effects are clearly illustrated in Figure 1 for which rRCM have been computed using a previous work on the rRCM calculation taking into account rigorous VLLE equilibria (Brehelin et al., 2006); the transformed variable coordinates (Ung and Doherty, 1995) are used with n-propyl acetate as the reference component. For the sake of better representation of the chemical and phase equilibria complexity, rRCM in molar composition are represented too in Figure 1 (bottom). As a consequence, great attention has to be paid to the chemical and phase equilibria determination in order to perform the design of such a process. Therefore, this article presents the first steps of an approach to the development of a RD process for the production of n-propyl acetate: the catalysed reaction kinetics are firstly investigated in order to employ a simulation environment based on an equilibrium stage model; in parallel pilot plant experiments are carried out in order to validate this simulation tool. On the basis of these results, an optimal startup strategy is proposed and several process configurations are studied in order to propose the best setup for high purity n-propyl acetate production. |

| These effects are clearly illustrated in Figure 1 for which rRCM have been computed using a previous work on the rRCM calculation taking into account rigorous VLLE equilibria (Brehelin et al., 2006); the transformed variable coordinates (Ung and Doherty, 1995) are used with n-propyl acetate as the reference component. 这些效果在图1中得以清晰地显示。在图1中，运用先前一个考虑了严格液三相平衡的关于rRCM 计算的工作，计算了rRCM ；图中采用转换变量坐标，以乙酸正丙酯为参考成分。For the sake of better representation of the chemical and phase equilibria complexity, rRCM in molar composition are represented too in Figure 1 (bottom).为了更好的显示化学药品和相平衡复杂性，rRCM 以摩尔组成的形式也在图1中表示（底部）。As a consequence, great attention has to be paid to the chemical and phase equilibria determination in order to perform the design of such a process.基于上述，为了执行这一过程的设计，对化学药品和相平衡倾注了极大关注。 Therefore, this article presents the first steps of an approach to the development of a RD process for the production of n-propyl acetate: the catalysed reaction kinetics are firstly investigated in order to employ a simulation environment based on an equilibrium stage model; in parallel pilot plant experiments are carried out in order to validate this simulation tool. 为此，本文展示了开发一种生产乙酸正丙酯的RD过程途径的初步：首先研究了催化反应动力学，以使用基于一个平衡阶段模型的模拟环境；开展了并行的中试以验证这一模拟工具。On the basis of these results, an optimal startup strategy is proposed and several process configurations are studied in order to propose the best setup for high purity n-propyl acetate production.以这些研究结果为基础，提出了优化的启动策略并研究了几个过程参数以提出得到乙酸正丙酯高生产纯度的最佳设置。 |
