Abstract: A fluid compressor system having an electro-magnetic throttle valve (EMTV) that utilizes magnetic forces supplied by an electromagnet to actuate the opening and closing of the valve. The fluid compressor system may include a control system that controls the position of a valve plate of the EMTV, allowing the EMTV to fully or partially actuate to a plurality of intermediate positions depending on a current supplied to the electromagnet by the control system. The control system may control a location of the valve plate with reference to the electromagnet by balancing the forces acting on the valve plate, such as electromagnetic forces supplied by the electromagnet, biasing forces supplied by biasing components, and gravitational forces acting on the valve plate. The EMTV may include a blowdown system configured to release a pressure within the fluid compressor system when the inlet on the EMTV is closed.

Abstract: A turbocharged compressor system using an Organic Rankine Cycle system to recover waste heat from a compression process. The Organic Rankine Cycle system circulates an organic fluid through an evaporator, where the organic fluid vaporizes and is expanded in a turbine section of a turbocharger to drive a compressor section of the turbocharger. The organic fluid vapor is condensed in a condenser and is pumped to the evaporator once again for recirculation. The compressor section of the turbocharger pre-compresses a working fluid before entering an airend in a compression system. As the working fluid exits the airend, it may be delivered to the evaporator, where the waste heat from the working fluid evaporates the organic fluid flowing in the Organic Rankine Cycle system. The working fluid may also be circulated between intercoolers in multi-stage compressor systems.

Abstract: A fluid compressor system having a pneumatic inlet/blowdown valve assembly that utilizes pneumatic pressure and vacuum available in the fluid compressor system for the actuation of an inlet valve and a blowdown valve. The actuation of the inlet valve and the blowdown valve is synchronized via a piston-cylinder actuator having a first piston and a second piston axially connected. The pneumatic blowdown/inlet valve assembly uses a first stage vacuum pressure to actuate the first piston and the second piston from an idle state where the inlet valve is closed to stop a flow of working fluid into the fluid compressor system and the blowdown valve is open to depressurize the fluid compressor system to an actuated state where the inlet valve is open to allow the flow of working fluid into a first airend and the blowdown valve is closed to allow a pressure buildup in the fluid compressor system.

Abstract: A compressor system includes an inlet for receiving a fluid stream, a compressor in communication with the inlet, a separator in communication with the compressor, and a vent. The compressor system also includes a flow diversion control device in communication with the inlet, the compressor, the separator, and the vent, where the flow diversion control device has a first port in fluid communication with the separator, a second port in fluid communication with the inlet, a third port communicatively coupled with the inlet, a fourth port in fluid communication with the vent, and a mechanical valve having a first orientation configured to connect the first port to the second port and the third port to the fourth port for unloading the compressor system, and a second orientation configured to connect the first port to the third port and the second port to the fourth port for loading the compressor system.
