精馏过程的控制,可以靠使用多点温度测量以估计产品成分和对操作变量进行投影变换的方法,来得到改进。结果,与单独塔板的恒定温度控制相比较,产品质量变化大为减少。使用对Marathon石油公司操作的脱丁烷塔收集的大约一年多的工厂数据,来推导出计算机模型。然后,由Cose Western基金大学和Marathon石油公司的一个工业大学对估计方法和它们对产品质量的预期控制 Distillation process control, you can rely on the use of multi-point temperature measurement to estimate the composition of the product and the operation of the variable projection transformation method to be improved. As a result, product quality changes are greatly reduced compared to constant tray temperature control. The computer model was derived using more than a year’s plant data collected from the debutanizer operated by Marathon Oil Company. Then, an estimation of the methodologies and their expected control of product quality was conducted by an industrial university at Cose Western University and Marathon Petroleum
