Abstract: Process fluid flow in the primary flow passage (70) of a compressor (20) is altered by selective inclusion of one or more tooth-like, annular circumferential flanges (48) in its secondary flow passage (72). The compressor's secondary flow passage is defined between opposing surfaces of a hub (40) of the impeller (26) and the opposing hub side (64) of the housing (21). The annular circumferential flange is coupled to the hub of the impeller and/or the hub side of the compressor housing within the secondary flow passage. A compressor incorporating one or more of the annular circumferential flanges in its secondary flow passage achieves more uniform flow velocity flow within the primary flow passage.

Abstract: A linear motor for moving a piston rod of a reciprocating compressor. The motor includes a guidance assembly having a moveable secondary carrier that is attached to the piston rod. The motor also includes at least one permanent magnet attached to the secondary carrier and at least one primary winding attached to the guidance assembly. In addition, the motor includes a controller that controls power supplied to the primary winding to generate a magnetic field that interacts with a magnetic field generated by the permanent magnet to provide a force that moves the permanent magnet, the secondary carrier and the piston rod in a reciprocating linear motion.

Abstract: A system and method are provided for blending a first fuel from a first fuel source with a second fuel from a second fuel source. The system may include a controller communicatively coupled with each of a plurality of sensors, a first plurality of valves including a first progressive valve, and a second plurality of valves including a second progressive valve. The first and second plurality of valves may be configured to selectively enable fluid communication between the first and second fuel sources and a power generation unit. The controller may be configured to receive a detected operating parameter from a sensor, compare the detected operating parameter to another operating parameter, and based on the comparison, transmit an instruction to at least one of the first progressive valve and the second progressive valve to enable the first fuel to blend with the second fuel before entering the power generation unit.
