On the start-up operation of distillation column, we studied three subjects.1. A characteristic function MT which is easily calculated at any instant by using the observed values of temperature in the column is useful in determining the optimum switching time from total reflux operation to steady-state operation where the initial composition in each tray is equal in value.The applicability of the characteristic function is examined experimentally for the more realistic startup of a distillation column with following steps. 1. Feed is supplied through the feed tray until holdup in each tray in the stripping section is filled up. 2. Total reflux operation is initiated. 3. Reflux is switched from total reflux operation to steady-state operation at appropriate switching time.2. The applicability of the characteristic function is examined numerically and experimentarlly in the case that the detecting point of temperature in distillation column is reduced.3. For the first step of realizing the automatic start-up operation of distillation using the artificial intelligence, the simullation is carried out based on the knowledge which is necessary in the operation of distillation column.

在精馏塔启动操作方面，我们进行了三个方面的研究。一个特征函数MT，这是很容易在任何时刻计算通过使用温度的观测值在柱中是有用的，以确定最佳切换时间从总回流操作到稳态操作，其中初始组成在每个托盘是相等的值。通过实验验证了特征函数在精馏塔实际启动过程中的适用性。1. 进料通过进料托盘供应，直到在剥离部分的每个托盘的堵塞被填满。2. 启动全回流操作。3. 回流在适当的切换时间从全回流操作切换到稳态操作。在精馏塔温度检测点降低的情况下，通过数值和实验验证了特征函数的适用性。在利用人工智能实现精馏塔自动启动操作的第一步，基于精馏塔操作所必需的知识进行了仿真。
