System and process for capture of H2S from gaseous process streams and process for regeneration of the capture agent
A system and process are disclosed for selective removal and recovery of H2S from a gaseous volume, e.g., from natural gas. Anhydrous organic, sorbents chemically capture H2S gas to form hydrosulfide salts. Regeneration of the capture solvent involves addition of an anti-solvent that releases the captured H2S gas from the capture sorbent. The capture sorbent and anti-solvent are reactivated for reuse, e.g., by simple distillation.
TASK-SPECIFIC IONIC LIQUID-DERIVED SYSTEM FOR SELECTIVE OXYGEN PRODUCTION (iEdison No. 0685901-23-0184)
Our hypothesis is that a small modular system could be engineered using solvent-based capture and pressure or thermal release of oxygen, to enable oxygen on demand for any combustion-related technology. Task-specific ionic liquid (TSIL)-TEMPO is selected as our base compound for screening selective oxygen generation process and has an unpaired electron, we anticipate a formation of weak complex enabling this fluid to be thermally reversible. TSIL-TEMPO can possibly have high gravimetric capacities of O2, via the diamagnetic supramolecular complex A (2:1 TSIL-TEMPO:O2) or the monodentate complex B (1:1).
INTERRUPTIBLE SHEAR-ASSISTED EXTRUSION
We have demonstrated, for aluminum alloy 6063, that the ShAPE process is capable or re-starting extrusion after the process is stopped, the die is retracted, and the die, billet, and extruded metal are allowed to cool to room temperature. This invention is not limited to AA 6063, but is applicable to any metal extruded by the ShAPE process. With ShAPE, we are able to use the heat generated by the rotating die to re-heat the die set and metal so the extrusion can proceed after stopping and cooling.
REACTOR ASSEMBLIES AND METHODS OF PERFORMING REACTIONS (iEdison No. 0685901-18-0022)
The purpose of this invention is to capture concentrated solar radiation, converting the energy to chemical energy at a higher efficiency and lower cost than prior art. This is accomplished by operating a high temperature endothermic reaction such as methane steam reforming where the heat of reaction is largely or completely provided by solar energy. A spiral counter-cross flow arrangement of reaction channels and recuperative heat exchange channels enables efficient thermal spreading of inhomogeneous solar irradiation. The reduction of hot spots leads to lower OPEX and CAPEX through improvements to reactor's operability under high flux conditions and longer reactor life by reducing thermal stress, respectively.
Autonomous Sensor Fish to Support Advanced Hydropower Development
An improved sensor fish with robust design and enhanced measurement capabilities. This sensor fish contains sensors for acceleration, rotation, magnetic field intensity, pressure, and temperature. A low-power microcontroller collects data from the sensors and stores up to 5 minutes of data on a non-volatile flash memory. A rechargeable battery supplies power to the sensor fish. A recovery system helps locating sensor fish. The package, when ready for use is nearly neutrally buoyant and thus mimics the behavior of an actual fish.

DEVICES AND METHODS FOR PERFORMING SHEAR-ASSISTED EXTRUSION, EXTRUSION FEEDSTOCKS, EXTRUSION PROCESSES, AND METHODS FOR PREPARING METAL SHEETS (iEdison No. 0685901-13-0018)
A process for forming extruded products using a device having a scroll face configured to apply a rotational shearing force and an axial extrusion force to the same preselected location on material wherein a combination of the rotational shearing force and the axial extrusion force upon the same location cause a portion of the material to plasticize, flow and recombine in desired configurations. This process provides for a significant number of advantages and industrial applications, including but not limited to extruding tubes used for vehicle components with 50 to 100 percent greater ductility and energy absorption over conventional extrusion technologies, while dramatically reducing manufacturing costs.
