分析了联合站原油沉降脱水系统的生产特性和生产过程中变量参数之间的关系。提出了一种改进的ＰＩＤ控制算法，并设计了联合站油水分离过程中的参数间能互相协调的控制方案。达到控制指标为Ｆ２≤３０％；约束条件为０．２５ＭＰａ≤ｐｓ≤０．３５ＭＰａ。控制方案在某联合站实施一年来，沉降脱水后的原油含水稳定在１０％～２０％范围内。
The relationship between the production characteristics of the crude oil settling and dehydration system and the variable parameters in the production process was analyzed. An improved PID control algorithm is proposed and a control scheme is designed to coordinate the parameters in the process of oil-water separation at the joint station. Achieve the control index of F2 ≤ 30%; the constraint condition is 0.25MPa≤ps≤0.35MPa. Control program In the implementation of a joint station a year, after the settlement of dehydrated crude oil water stable at 10% to 20% range.
