Abstract: A system includes a gas turbine comprising a compressor section, combustor section, and a turbine section. The system further includes a first fuel line and a second fuel line coupled to the gas turbine. The system also includes a feed compressor disposed along the first fuel line upstream of the gas turbine. The feed compressor is configured to pressurize the first fuel provided to the gas turbine. Further, the system includes fuel flow maintenance system configured to provide a pressurized fuel to the first fuel line upstream of the feed compressor in response to an interruption in a flow of the first fuel along the first fuel line to the gas turbine that triggers a transition from the first fuel in the first fuel line to the second fuel in the second fuel line.

The system also includes a scrubber disposed directly downstream of the gasification section and configured to filter the syngas. The system also includes a first expander disposed along the flow path directly downstream from the scrubber and configured to expand the syngas. The syngas comprises an untreated syngas.

Abstract: A heat recovery system for use with a gasification system is provided. One system includes a gasification system and an organic Rankine cycle system coupled to the gasification system. The organic Rankine cycle system is configured to receive heated fluid from the gasification system and to deliver cooled fluid to the gasification system. The organic Rankine cycle system is configured to produce power by converting heat energy in the heated fluid.

Abstract: A gasification system including a gasifier, a feed injector, and a fuel feed system that includes a first feed line, a second feed line, and a controller that includes a processor. The processor is programmed to enable the first feed line to supply a fuel gas into the feed injector, enable the second feed line to supply oxygen into the feed injector, receive instructions to add a slurry to the gasifier, prevent the first feed line from supplying the fuel gas into the feed injector, enable the first feed line to supply the slurry into the feed injector, enable the second feed line to simultaneously supply the oxygen and the inert gas into the feed injector, and prevent the second feed line from supplying the inert gas into the feed injector.

Abstract: Packets received at a network appliance are classified according to a packet classification rules based on flow state information maintained by the network appliance and evaluated for each packet as it is received at the appliance on the basis of OSI Level 2-Level 4 (L2-L4) information retrieved from the packet. The received packets are acted upon according to outcomes of the classification; and the flow state information is updated according to actions taken on the received packets. The updated flow state information is then made available to modules performing additional processing of one or more of the packets at OSI Layer 7 (L7).

Abstract: A system including a feedstock supply system that includes a first pump configured to supply a first feedstock to a first gasifier along a first supply conduit, a second pump configured to supply a second feedstock to the first gasifier along a second supply conduit, and a pressure vessel disposed along a first conduit loop. The feedstock supply system is configured to circulate the first feedstock through the first conduit loop to raise a first pressure of the first feedstock to a first threshold pressure in the pressure vessel. The feedstock supply system is also configured to control a first transition from the second pump to the first pump after the first pressure reaches the first threshold pressure. The first transition includes a first change from the second feedstock to the first feedstock for supply to the first gasifier.

Abstract: A digital certificate associating a unique identifier for a computer-based appliance with an authentication key pair for that appliance is obtained from a certificate authority using a different, manufacturing key pair for the appliance. The manufacturing key pair may be generated by the appliance at or about its time of manufacture. The public key portion of the manufacturing key pair along with the unique identifier for the appliance may be provided via secure means to the certificate authority prior to the request for the digital certificate concerning the authentication key pair. Eventually, the digital certificate associated with the authentication key pair may be used by the appliance when joining a network, as part of a one-way or two-way authentication process.

Abstract: A first computer-based device is authenticated at a second computer-based device communicatively coupled thereto through use of a unique identifier and an encrypted token, each received from the first device. Following the authentication, configuration information for the first device is sent from the second device to the first device and the first device is authorized to join a network that includes the second device. Further, permissions related to the network may be granted to the first device.

Abstract: Techniques for suspending a TCP three-way handshake, offering the partial connection to an L-7 application or module at a proxy to perform further processing, and then allowing the L-7 application or module to instruct the proxy's network kernel to perform various actions are described. In various embodiments these actions may include: silently dropping the connection, verbosely rejecting the connection, accepting and processing the connection locally, or forwarding the connection to another proxy or the original destination. This additional functionality is provided, in one particular embodiment, via extensions to the POSIX socket API.
