Abstract: A centrifugal separator for separating liquid and solid contaminants from flowing gas and for separating certain liquids from other liquids. The centrifugal separator finds novel application as a flow stabilization system wherein the separator vessel is coupled into a natural gas flowline upstream of flow measurement equipment to minimize fluctuations of flowing natural gas, which may contain solid and liquid contaminants. The separator vessel defines an internal fluidic column within which is developed rapid cyclonic gas flow activity for separation of any liquid and solid contaminants from the gas. The vessel also defines a sump for accumulating and/or draining contaminants separated from the flowing natural gas in the fluidic column. An outlet extends into the vessel positioning an outlet opening to receive only gas from the cyclonic circulation of natural gas.
