Integrated separator turbine

A fluid processing system, comprising:

• a steam turbine assembly comprising:
• a rotary shaft,
• rotor blades disposed about the rotary shaft and coupled therewith, and
• stator vanes disposed circumferentially about the rotary shaft and positioned upstream of the rotor blades, the stator vanes defining an end wall passage extending from an inlet to an outlet of the stator vanes;
• and
• a rotary separator coupled with the rotary shaft of the steam turbine assembly and positioned directly upstream of the steam turbine assembly, the rotary separator comprising:
• an inlet end configured to receive a multiphase fluid,
• an outlet end fluidly coupled with the steam turbine assembly, and
• a separation chamber extending from the inlet end to the outlet end, the separation chamber configured to separate a liquid portion from the multiphase fluid to thereby provide a substantially gaseous fluid to the steam turbine assembly.

A method for separating a liquid portion from a multiphase fluid for a fluid processing system, comprising:

• receiving the multiphase fluid from a fluid source at an inlet end of a rotary separator fluidly coupled with the fluid source;
• rotating a rotary shaft, the rotary shaft common to the rotary separator and a steam turbine assembly positioned downstream of the rotary separator;
• separating the liquid portion from the multiphase fluid in a separation chamber of the rotary separator to provide a substantially gaseous fluid;
• and
• directing the substantially gaseous fluid directly to an inlet of the steam turbine assembly via an outlet end of the rotary separator.
