Abstract
Apparatus and method for decreasing chemical requirements for chemicals injected into a stream a low concentrations, such as for dehydration of crude oil, are provided. An algorithm is used to provide a signal to decrease chemical injection rate of a variable rate pump if the water content of the treated oil has not exceeded a preset value in a preset time and to increase chemical injection rate if the water content of the treated oil is exceeded within a preset time. The algorithm allows the control system to learn from previous experience.
