CONTENTS General Description Types of Separator Operation of Separator Safety Devices in Separator Conclusion
General Description Effluent from well is a 3-phase combination, A gaseous phase A hydrocarbon liquid phase (oil and condensate) An aqueous phase (formation water) Principle of separator is for separating gases, oil/condensate and water contained in the effluent leaving a well, by using the differences in their densities before continue to next process depend on the result of products (gas and oil/condensate).
Types of Separator Types of Separators: Based on Shape; Horizontal Vertical Spherical Based on Function; Test Separator Production Separator Based on phase; 2 Phase 3 Phase Based on operating pressure; HP Separator MP Separator LP Separator

Conclusion Separator is an equipment, which holds a major contribution in production process of oil and gas. It used to separate the hydrocarbon, withdraw water, sand and other unwanted particle from wells.
