Abstract: A system and method for optimizing operation of a rotating packed bed desorber or regenerator wherein a rich solvent is input and CO2 product and lean solvent are output includes collecting condensed water from a regeneration section of a rotating packed bed desorber system. The collected condensed water is then repressurized and reheated to generate steam and the steam is injected into the rotating packed bed desorber or regenerator as stripping vapors while heating rich solvent.

Abstract: A system and method for removing a component from a gas stream. The method includes absorbing the component from a gas stream in a solvent, separating the component from the solvent, and recycling the solvent back to the absorbing step. The absorbing is desirably performed by a counter-current contact between the solvent and the gas stream, such as using a rotating packed bed absorber. The rotating packed bed absorber is paired with a multistage solvent regeneration system configured to receive a rich solution from the rotating packed bed absorber and return a recycled lean solution to the rotating packed bed absorber.

Abstract: A system and method for producing hydrogen and/or power at scale. A partial combustion of a carbonaceous gaseous and/or liquid feed with an oxygen-containing feed generates heat for pyrolyzing non-combusted carbonaceous gaseous and/or liquid feed materials to produce an effluent including hydrogen, carbon monoxide, carbon dioxide, water, and nitrogen. Electrolysis powered by a renewable energy source converts water to hydrogen and oxygen for the oxygen-containing feed. Hydrogen is collected from the electrolysis, and also from the effluent, and sent to a hydrogen-based power generator.

Each liquid distributor also includes a dome coupled to the conduit at an end of the conduit distal from the plate. The conduit defines openings disposed where the dome is coupled to the conduit permitting the liquid to flow from the conduit to the dome. The liquid is to flow over an edge of the dome.

Abstract: Processes for converting methane and/or other hydrocarbons to synthesis gas (i.e., a gaseous mixture comprising H2 and CO) are disclosed, in which at least a portion of the hydrocarbon(s) is reacted with CO2. At least a second portion of the methane may be reacted with H2O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (?H) and the required energy input, compared to “pure” dry reforming in which no H2O is present. Such dry reforming (reaction with CO2 only) or CO2-steam reforming (reaction with both CO2 and steam) processes are advantageously integrated with Fischer-Tropsch synthesis to yield liquid hydrocarbon fuels. Further integration may involve the use of a downstream finishing stage involving hydroisomerization to remove FT wax.

Abstract: A method for processing proppant from a well. A plurality of proppant samples are collected during drilling of a well for imaging analysis. In addition to imaging analysis a further correction factor is determined for the samples using additional analysis on a portion of the samples. Determining and applying the correction factor to the imaging results provides a more accurate proppant log. The additional analysis can be by scanning electron microscopy, such as for differentiating the silicon proppant particles from other elemental particles resulting from the drilling.

Abstract: A system and method for communicating operation failure of a remote pipeline pneumatic device. A flow detector is used in combination with the pipeline pneumatic device. A controller in combination with the flow detector and a long range communication transmitter communicates an alarm upon detecting a predetermined flow, such as outside an expected amount. The controller can initiate a flow timer upon the actuation of the pneumatic device, and transmit an alarm upon the flow timer exceeding a predetermined value representing the expected amount.
