Distillation is a very important operation for purification and separation in Chemical Engineering field. The determination of the optimal distillation sequence is key to minimize the total investment and operating cost and it can be posed as a mixed integer‐linear programming (MILP) problem. To solve them and due to the high number of variables and equations, it is required the use of specific software, for example, General Algebraic Modeling System or A Mathematical Programming Language. However, these software involve long training for the student to adequately harness them. The use of non‐specialized, widespread and easy to access software programs is a good opportunity to tackle the teaching of some typical optimization problems. One of them is the Microsoft Excel Solver Tool, accessible by any engineering student who usually learn its use in the first years of their degree, so that MS‐Excel is already known when students deal with optimization problems. Additionally, it is scarcely known that Microsoft Excel Solver may tackle both real and binary variables, so it is possible to leverage it for solving MILP problems. This paper presents an example of distillation sequences problem aimed to separate a mixture comprising four different compounds with a minimal operational cost (which constitutes a MILP optimization problem indeed) solved using Excel Solver tool. This methodology was taught successfully to the students of the Master of Chemical Engineering of Rey Juan Carlos University and Autónoma University of Madrid.

microsoft excel求解器工具在蒸馏序列问题优化中的应用

蒸馏是化工领域中一个非常重要的提纯和分离操作。确定最佳蒸馏顺序是最小化总投资和运营成本的关键,它可以作为混合整数线性规划 (MILP) 问题提出。为了解决这些问题,并且由于变量和方程的数量很多,需要使用特定的软件,例如通用代数建模系统或数学编程语言。但是,这些软件需要对学生进行长时间的培训才能充分利用它们。使用非专业、广泛且易于访问的软件程序是解决一些典型优化问题教学的好机会。其中之一是 Microsoft Excel 求解器工具,任何通常在他们学位的第一年学习其使用的工程专业学生都可以访问,因此当学生处理优化问题时,MS-Excel 已经为人所知。此外,很少有人知道 Microsoft Excel 求解器可以同时处理实数和二进制变量,因此可以利用它来解决 MILP 问题。本文介绍了一个蒸馏序列问题的例子,旨在以最小的运营成本(这实际上构成 MILP 优化问题)分离包含四种不同化合物的混合物,使用 Excel 求解器工具解决。这种方法论成功地传授给了胡安卡洛斯国王大学和马德里自治大学化学工程硕士的学生。这样学生在处理优化问题时就已经知道了 MS-Excel。此外,很少有人知道 Microsoft Excel 求解器可以同时处理实数和二进制变量,因此可以利用它来解决 MILP 问题。本文介绍了一个蒸馏序列问题的例子,旨在以最小的运营成本(这实际上构成 MILP 优化问题)分离包含四种不同化合物的混合物,使用 Excel 求解器工具解决。这种方法论成功地传授给了胡安卡洛斯国王大学和马德里自治大学化学工程硕士的学生。这样学生在处理优化问题时就已经知道了 MS-Excel。此外,很少有人知道 Microsoft Excel 求解器可以同时处理实数和二进制变量,因此可以利用它来解决 MILP 问题。本文介绍了一个蒸馏序列问题的例子,旨在以最小的运营成本(这实际上构成 MILP 优化问题)分离包含四种不同化合物的混合物,使用 Excel 求解器工具解决。这种方法论成功地传授给了胡安卡洛斯国王大学和马德里自治大学化学工程硕士的学生。本文介绍了一个蒸馏序列问题的例子,旨在以最小的运营成本(这实际上构成 MILP 优化问题)分离包含四种不同化合物的混合物,使用 Excel 求解器工具解决。这种方法论成功地传授给了胡安卡洛斯国王大学和马德里自治大学化学工程硕士的学生。本文介绍了一个蒸馏序列问题的例子,旨在以最小的运营成本(这实际上构成 MILP 优化问题)分离包含四种不同化合物的混合物,使用 Excel 求解器工具解决。这种方法论成功地传授给了胡安卡洛斯国王大学和马德里自治大学化学工程硕士的学生。
