A burner and methods of using the burner. The burner produces a flame from combustion air and fuel gas. Flue gas, also produced, can be withdrawn and recycled to the burner. A cooling or condition gas, such as ambient air, may be mixed with the flue gas to reduce its temperature. The burner may also utilize a stage injection so that a portion of the produced flue gas is recycled internally.

Processes and apparatuses for heating process fluid in a furnace. Fuel to the furnace is either hydrocarbons or hydrogen. The fuels may be sent to different furnaces or be sent at different times to the same furnace. Furnaces that are configured to receive both types of fuels may have different exhaust paths. An exhaust path for hydrocarbon fuel flue gas includes a carbon capture process zone.

Processes and apparatuses for burning a hydrogen fuel and a hydrocarbon fuel

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.

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

Integrated hydrogen production and bio-renewable conversion process

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

Method of producing a hydrogen-enriched product and recovering COin a hydrogen production process unit

A process and apparatus for producing a hydrogen-enriched product and recovering COfrom 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 COand some impurities. The CO-rich tail gas stream is compressed and sent to a COrecovery unit, where a CO-enriched stream is recovered. The CO-depleted overhead gas stream is recycled to the PSA system that produces at least two product streams.

A burner and methods of using the burner. The burner utilizes bypass conduits to separate the combustion air that is passed to the primary combustion zone into two or more portions. The two portions are injected into the primary combustion zone at different points so as to reduce the flame temperature. A NOx reducing medium may be mixed with the combustion air in the bypass conduit. The NOx reducing medium may be flue gases from a combustion chamber having the primary combustion zone.

Methods and systems for monitoring a flare burner with a camera. The methods and systems which may indicate to operators the presence or absence of one or more of smoke, flare flame, and steam plume and record those indications or measurements. Additionally, the methods and systems may confirm whether compliance with local regulations on visual emissions, smoke plume is achieved. The methods and systems automatically adjust the delivery rate of key inputs including measures assist fuel gas, purge gas, steam and/or air simultaneously to maintain or attain compliance with said local regulatory requirements. Also, methods for a machine learning process for using controller inputs to identify normal and abnormal flare states and provide visual indications and flare operation recommendations.

Processes and systems for analyzing images of a flare burner

Process for measuring emission for a flame in an open combustion environment. A captured image is received from each of a plurality of image capturing devices in at least one selected spectral band. Each of the plurality of image capturing devices is trained on the flame from the combustion process from a different perspective view angle. A spectral path length of the flame in the at least one spectral band is estimated from the captured images. Emitted radiance of the flame is estimated from the captured images, and a temperature of the flame is estimated from the estimated emitted radiance. A gas species concentration of the flame is estimated from the temperature of the flame and the spectral path length of the flame. Emission for the flame is measured from the gas species concentration.

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.

A heater coil for heating a feedstock comprises an inlet manifold and an outlet manifold having longitudinal extensions that are parallel. A plurality of process tubes are suspended from and in fluid communication with the inlet manifold and the outlet manifold. Each process tube comprises an inlet leg coupled to the inlet manifold, an outlet leg coupled to the outlet manifold, and a U-shaped portion disposed between the inlet leg and the outlet leg for passage of the feedstock therethrough. The inlet manifold and the outlet manifold are elevated with respect to the plurality of process tubes. Each of the plurality of process tubes is aligned such that a width of the plurality of process tubes extends along a direction that is not perpendicular to the longitudinal extensions of the inlet and outlet manifolds.
