In this paper, we develop a simplified control-oriented model of a compact flotation unit (CFU), which removes residual oil from produced water in oil and gas production systems. CFU is a class of separators that exploits the synergy between separation effects of a swirling flow and the effect of flotation, in which small gas bubbles attach to the oil droplets and float to the top of the separator, where they are removed. The purified water flows downward, and is removed from the bottom. Our CFU model consists of a simplified initial swirl separation part and a flotation part, in which populations of oil droplets, gas bubbles without oil droplet, and gas bubbles with oil droplet attached are tracked spatially. After analyzing the model, we use it as a basis for designing a control structure that operates the separation system optimally.

用于优化和控制的紧凑型浮选机的简化第一性原理模型

在本文中，我们开发了一种紧凑型浮选单元（CFU）的面向控制的简化模型，该模型可从油气生产系统中的采出水中去除残留油。CFU是一类分离器，利用旋流分离效果和浮选效果之间的协同作用，其中小气泡附着在油滴上并漂浮到分离器的顶部，然后将其除去。净化水向下流动，并从底部去除。我们的CFU模型包括一个简化的初始旋流分离部分和一个浮选部分，其中空间上跟踪油滴，无油滴的气泡和附着有油滴的气泡的数量。分析模型之后，我们将其用作设计优化操作分离系统的控制结构的基础。
