The right instrumentation is critical for effective separator operation.
Level control in a separator controls the interface between the water and the oil (liquid hydrocarbons). There must be sufficient time to create a layer of oil above the free water. The water controller controls the interface level by creating a pad between the water and oil. A weir is used to separate the oil from the water and another controller is used to control the oil level. The natural gas flows on the top of the separator. To maintain the interface level and ensure optimal production out of the separator, the instrumentation is integral to the process.
