Abstract: An apparatus and process for dispensing a cryogenic fluid (e.g. a cryogenic liquid, liquid hydrogen, liquid natural gas, etc.) can include feeding liquid from a storage tank to one or more dispenser feed vessels, subsequently pressurizing the vessel(s) with gas to a pre-selected dispending pressure, and then outputting the liquid from the dispenser feed vessel(s) to one or more dispensers. After dispensing is complete, fluid from within the vessel(s) can be displaced and used for other processing. Embodiments can be configured to help limit or avoid venting while also providing improved operational flexibility and efficiency.

Abstract: A method for purifying a crude hydrogen feed stream utilizes an adsorbent having a N2/Ar selectivity ranging from 2 to 4 at 30° C. and a Henry's law coefficient for argon ranging from 0.15 to 1.0 mmole/g/atma at 30° C. The composition of crude hydrogen streams from processes in which carbon dioxide is captured necessitates new criteria for adsorbent selection to improve recovery.

Abstract: A method comprising generating a first process gas stream in a first plant; generating a process heat utility in a second plant; contacting the first process gas stream with a first solvent to produce a first CO2-depleted process gas stream and a first CO2-enriched solvent; regenerating the first CO2-enriched solvent in a regeneration system to produce a CO2-depleted solvent; wherein the process heat utility provides at least a portion of the heating duty for the regeneration system; wherein the first solvent comprises at least a portion of the CO2-depleted solvent.

Abstract: An apparatus and process for argon recovery can be configured so that an argon-enriched stream including oxygen therein can be recycled to a column for air separation and subsequent argon separation to provide improved argon recovery with reduced power. The recycling of this argon-enriched stream can be provided such that there is sufficient nitrogen within the column to facilitate separation of argon from oxygen within the column so additional argon that can be provided via the recycling can be separated and purified instead of being output as a waste stream or otherwise lost.

Abstract: A process and apparatus for recovering at least argon from a feed gas that can provide an improved recovery of argon as well as an improvement in operational efficiency. Some embodiments can be adapted so that the improved argon recovery can also be obtained with improved condenser operation for an argon column without requiring an increase in power for the recovery of the argon. Some embodiments can utilize a reboiler positioned near or at the bottom of argon recovery column to increase boil-up therein and/or provide added heat duty to drive a condenser of the argon recovery column to provide improved argon recovery.

Abstract: An adsorption system having at least one adsorber retaining a bed of adsorbent material can be configured to provide enhanced purification of fees having relatively low concentrations of hydrogen or helium. Embodiments can utilize an activated carbon layer between at least one upstream layer and at least one downstream layer. The activate carbon layer can include activated carbon can have a pre-selected surface area (SA), bulk density, total open pore volume (TOPV), and/or ratio of TOPV to surface area (TOPV/SA).

Abstract: An apparatus and process for steam reforming can be configured to produce at least one product with reduced carbon dioxide and/or nitrogen oxide emissions. Some embodiments can be better adapted for retrofitting a pre-existing steam reforming process while other embodiments can be better adapted for use in a newly constructed facility. Embodiments can be configured to utilize a synthetic air oxidant to provide combustion that results in formation of a flue gas having relatively high carbon dioxide concentrations that may also have low nitrogen and low nitrogen oxide concentrations. A control system can be configured for utilization in such embodiments to control the steam reforming process and/or oxidant formation process as well. Some embodiments can also be configured to provide carbon dioxide recovery that can permit recovery of a second product stream comprised of carbon dioxide.

Abstract: An apparatus and process for oxygen production can be configured to utilize flash vapor losses, recovery of regeneration heat and/or utilize a compressor to provide better heat integration and/or less wasteful processing for the recovery of oxygen that can be obtained from electrolysis (e.g., operation of one or more electrolyzers). Some embodiments may utilize all three of these features while other embodiments may use only one of these features or a combination of two of these features.
