Recommendations on Selection and Design of Pulsation Dampeners for Oil-Gas Field Separating Plants

Abstract

Processes in pulsation dampeners are described and recommendations on the selection and design of pulsation dampeners are given. Pulsation dampeners should be installed before the separators or heat exchangers at the inlet of the first separation stage. Pulsation dampeners are not needed before other separation stages. Three-pipe pulsation dampeners with a Venturi nozzle at the inlet are installed before the separators that have separate liquid and gas inlets. A Venturi nozzle is installed before the separators and heat exchangers that have a single mixture inlet. The flow area of the Venturi nozzle neck should be smaller than the flow area of the pulsation dampener–throttle track leading to the next separation stage.
