研究了以甘油为夹带剂的乙醇萃取精馏的最佳设计和操作条件。将优化问题表述为一个混合整数非线性规划问题。离散变量决定了柱的级数及其进料级位置。连续变量包括均衡模型变量和操作变量。优化问题的求解是通过一种结合随机和确定性算法的两级策略来实现的。所得结果为满足问题约束条件的生物乙醇工业生产建立了一个经济准则最大化的过程。
The extractive distillation of ethanol using glycerol as entrainer is studied in order to find its optimal design and operating conditions. The optimization is formulated as a mixed integer nonlinear programming (MINLP) problem. The discrete variables determine the number of stages of the columns and their feed stage locations. The continuous variables include the variables of the equilibrium model and operating variables. The solution of the optimization problem is achieved through a two-level strategy that combines stochastic and deterministic algorithms. The result obtained establishes the process that maximizes an economic criterion for the industrial production of bioethanol satisfying the problem constraints.
