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 and oil level controllers maintain the appropriate interface level between water and oil. A weir is used to separate the oil from the water. 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.
