Multiple modular in-line rotary separator bundle

A modular fluid separator assembly, comprising:

• a pressurized casing having a fluid outlet assembly, a drain, and a fluid entrance assembly including a flow divider defining sections, distribution vanes disposed upstream the flow divider, and a ramp disposed upstream the flow divider, the distribution vanes and the ramp being configured to distribute a mixed fluid flow;
• a plurality of flow guides fluidly coupled to the flow divider, each flow guide of the plurality of flow guides being configured to receive the mixed fluid flow from one of the sections of the flow divider;
• a plurality of rotary separators disposed in parallel in the pressurized casing, each rotary separator of the plurality of rotary separators having a discharge and an inlet fluidly coupled to one of the plurality of flow guides, and defining an outlet passage in fluid communication with the drain, wherein each rotary separator of the plurality of rotary separators is configured to separate the mixed fluid flow and to expel a higher-density component thereof to the drain;
• and
• an outlet manifold extending from and fluidly coupling the discharge of each rotary separator of the plurality of rotary separators to the fluid outlet assembly,
• wherein each rotary separator of the plurality of rotary separators includes
• a stationary housing defining circumferentially-extending slots therein, the circumferentially-extending slots at least partially providing the outlet passage;
• and
• a rotatable drum disposed in the stationary housing, the rotatable drum configured to rotate to at least partially separate the higher-density component of the mixed fluid flow from a lower-density component thereof.

A method for separating a higher density component of a mixed flow from a lower density component of the mixed flow, comprising:

• receiving the mixed flow through a fluid entrance assembly of a pressurized casing;
• dividing the mixed flow;
• introducing the divided mixed flow to a plurality of flow guides;
• distributing the mixed flow in the fluid entrance assembly with a ramp disposed upstream of the plurality of flow guides;
• receiving the mixed flow from the plurality of flow guides with a plurality of rotary separators disposed in parallel in the pressurized casing;
• centrifuging the mixed flow in the plurality of rotary separators to at least partially separate the higher-density component of the mixed flow from the lower-density component thereof;
• expelling at least a portion of the higher-density component of the mixed flow from the plurality of rotary separators via an outlet passage defined in each rotary separator of the plurality of rotary separators;
• draining the at least a portion of the higher-density component of the mixed flow through a drain in the pressurized casing;
• receiving at least a portion of the lower-density component from the plurality of rotary separators in an outlet manifold;
• and
• discharging the at least a portion of the lower-density component through a fluid outlet assembly of the pressurized casing.
