Abstract :
The produced water of oilfield is one of the primary contaminative sources of oilfield ecosystem, which includes large quantity of dirty mire mixed with the oil, sulfide, etc. Meanwhile, its direct rowing would result in serious pollution. Purifying this kind of produced water has been emphasized by more and more oil-fields. This paper presented the control algorithm of PH which is based on the PH control of the output of reactor. The control diagram of controlled object and the relevant controller are proposed in this article according to the produced water treatment process. This paper is to resolve the actual problem and aim of studying the control method of the system with time-delayed, and discuss the application of the Smith estimate control method and fuzzy control method in pharmacy dosing system.
