Abstract: A process and apparatus for producing a hydrogen-enriched product and recovering CO2 from an effluent stream from a hydrogen production process unit are described. The process utilizes a CO2 recovery system integrated with a PSA system that produces at least two product streams to recover additional hydrogen and CO2 from the tail gas stream of a hydrogen PSA unit in the hydrogen production process.

Abstract: A process and apparatus for producing a hydrogen-enriched product and recovering CO2 from an effluent stream from a hydrogen production unit are described. The effluent from the hydrogen production unit, which comprises a mixture of gases comprising hydrogen, carbon dioxide, water, and at least one of methane, carbon monoxide, nitrogen, and argon, is sent to a PSA system that produces at least two product streams for separation. The PSA system that produces at least two product streams separates the gas mixture into a high-pressure hydrogen stream enriched in hydrogen, optionally a second gas stream containing the majority of the impurities, and a low-pressure tail gas stream enriched in CO2 and some impurities. The CO2-rich tail gas stream is compressed and sent to a CO2 recovery unit, where a CO2-enriched stream is recovered. The CO2-depleted overhead gas stream is recycled to the PSA system that produces at least two product streams.

Abstract: A bio-renewable conversion process for making fuel from bio-renewable feedstocks is combined with a hydrogen production process that includes recovery of CO2. The integrated process uses a purge gas stream comprising hydrogen from the bio-renewable hydrocarbon production process in the hydrogen production process.

Abstract: A burner apparatus and process are described. The burner apparatus includes an inlet chamber in communication with a combustion chamber. A primary conduit delivers fuel gas to the combustion chamber. Each of a plurality of primary tips is located in the throat of the burner tile. Each of a plurality of cavities is disposed on a downstream wall of the burner tile and stabilize the flame. The primary tips have an end port and a lateral port. A secondary conduit provides fuel gas to a plurality of secondary tips. In a passive control mode, the fuel gas to the primary tips and secondary tips is a mixed gas comprising flue gas and fuel gas. In an active mode, valves are provided to proportion the amount of fuel gas fed to the primary tips and the amount of flue gas provided to the secondary tips.

Abstract: A flare burner for burning combustible waste gases with a manifold, at least two arms, and a plurality of outlets disposed on the plurality of arms. The arms may be perpendicular to the manifold. The arms may also extend outwardly from the manifold. The arms may extend into annuli, to produce oppositely flowing exit gas. A curved dispersing surface may be disposed above the manifold. The arms may comprise a curvilinear shape or include both a linear and a curvilinear portion. The arms are unequal in length and may curve in an opposite direction from each other. The outlets are configured and spaced such that flame is short relative to size of the flare burner.

Abstract: A process is provided for analyzing and visualizing conditions of a combustion process in an enclosure, and includes steps of providing continuously updated images of the enclosure for visualization of the enclosure to a user, using a viewing device having a display representing a virtual window of the enclosure; detecting a viewing angle and a viewing position of the user relative to the enclosure; illustrating an interior prospect of the enclosure relative to the viewing angle and position of the user based on the images of the enclosure; and adjusting, in realtime, the illustration of the interior prospect of the enclosure as at least one of the viewing angle and position of the user is changed for reflecting a changed view of the user.

Abstract: A process is provided for mapping temperatures in an enclosure during a combustion process. A device setting of an image-capturing device is provided. An intensity-temperature mapping is generated by performing an intensity-temperature calibration based on an intensity of an image pixel in a field of view (FOV) generated by the image-capturing device, a corresponding temperature measurement, and a selected device setting. Each emitted radiation of selected regions is detected based on a first image in the FOV. At least one region is determined whether the region is poor responsive, based on the intensity-temperature mapping associated with the device setting. The at least one poor responsive region is replaced with acceptable regions unaffected by the saturation from at least one other image captured at a different device setting for higher temperature resolution.

Abstract: A process is provided for mapping temperatures in an enclosure. A spectral band for a multi-spectral image-capturing device is selected. An intensity-temperature mapping is generated by performing an intensity-temperature calibration based on an intensity of an image pixel in a field of view (FOV) generated by the multi-spectral image-capturing device, a corresponding temperature measurement, and a selected device setting of the image-capturing device. An emitted radiation is detected based on a first spectral image in the FOV. At least one region is determined whether it is poor responsive, which is underexposed or overexposed, such that an accurate temperature is unable to be estimated based on a temperature value associated with the spectral band. Temperatures of the at least one poor responsive regions are replaced with temperatures from corresponding acceptable regions from at least one other spectral image to provide an extended temperature mapping of the enclosure.
