Abstract:
Systems and methods for reducing the energy requirements for carbon dioxide capture are described. Heat from system processes, such as steam condensation and hot flue gas, is utilized to heat reflux liquid utilized in release of carbon dioxide from absorbent solvent.
Abstract:
Systems and methods of CO2 desublimation are presented in which refrigeration content is retained within the system. Most preferably, refrigeration content is recycled by providing the refrigeration content of a CO2-lean feed gas to the CO2-containing feed gas and to pre-cooling of a desublimator, and/or by providing refrigeration of effluent of a desublimator in regeneration to a refrigerant in a closed refrigeration cycle for deep-cooling of another desublimator.
Abstract:
Systems and processes for reducing carbon capture emissions are described. The process involves introducing a radical species into a decarbonized combustion gas. The radical species react with residual amines or unwanted compounds in the decarbonized combustion gas, thus reducing the concentration of residual amines or unwanted compounds in the exhaust gas. The system includes a carbon capture absorber with non-thermal plasma generator configured to provide radical species reducing the concentration of residual amines or unwanted compounds in the exhaust combustion gas.
Abstract:
Advanced oxygen enrichment technologies for Claus plants are presented that provide an oxygen rich gas stream to the Claus burner of the thermal stage and one or more oxygen rich bypass gas streams to at least one of the catalytic stages to so increase the capacity of the plant while reducing the amount of recycle gases needed for flame temperature moderation.
Abstract:
Friction Stir Welding (FSW) devices and methods for simultaneously welding both sides of an arcuate joint are described. The FSW method includes the step of operating a FSW tool and an anvil on the exterior surface of the joint and simultaneously operating another FSW tool and anvil on the interior surface of the joint. The anvils are positioned in a juxtaposing manner to the FSW tools, and move in tandem with the FSW tools, thus providing a supporting force to the FSW tools during their operation.
Abstract:
Sentiment-based program management systems and methods are presented. A sentiment analysis engine obtains a set of terms (e.g., words, phrases, etc.) from a semantic terminology database where the terms are associated with a target capital program (e.g., large scale construction, etc.). The engine uses a semantic model related to the target program to analyze a set of program status documents term-by-term, especially analyzing documents related to a performance metric (e.g., milestones, etc.). Each term in the document found in the set of terms can be assigned a connotation or other sentiment value according to the model, possibly based on a context. The engine compiles a complete program sentiment from documents and presents the program sentiment with respect to one or more related performance metrics.
Abstract:
The inventive subject matter provides apparatus, systems and methods by which one can safely and effectively store fluids in undersea environments. Fluid is stored in a flexible bladder that is at least partially enclosed in a vessel. The bladder is coupled to a support, which supports the weight of the bladder with the aid of a support driver. A sensor may be used to monitor the position of the support, allowing determination of the volume of the bladder.
Abstract:
A pile and foundation modeling system for creating a three-dimensional (3D) model of foundations is presented. In one aspect of the invention, the pile and foundation modeling system includes a foundation database that stores several configurable foundation geometries, an interface, and a modeling engine that is coupled to the interface and the foundation database. The interface is configured to receive foundation data that includes parameters associated with a construction project. The modeling engine is configured to (i) obtain the foundation data via the interface, (ii) instantiate pile and foundation objects based on applying the foundation data to the configurable foundation geometries, (iii) generate a three-dimensional pile and foundation model according to the instantiated pile and foundation objects, and (iv) configure an output device to render the three-dimensional pile and foundation model.
Abstract:
A multi-drum coking system wherein at least one drum, and preferably all drums, are fluidly coupled to at least two other drums. The system allows a vapor of one drum to be directed to multiple drums to prevent unnecessary non-productivity of coke drums.
Abstract:
Gas processing plants and methods are contemplated in CO2 is effectively removed to very low levels from a feed gas to an NRU unit by adding a physical solvent unit that uses waste nitrogen produced by the NRU as stripping gas to produce an ultra-lean solvent, which is then used to treat the feed gas to the NRU unit. Most preferably, the physical solvent unit includes a flash unit and stripper column to produce the ultra-lean solvent.
