Abstract: A method for corrosion control is disclosed, wherein the method includes limiting all components involved in sulfuric acid formation to low levels. The components include, but may not be limited to oxygen, nitrogen oxides, sulfur oxides, and H2S. The method may also include maintaining the H2S level above typical pipeline concentrations to inhibit the reactions to form sulfuric acid in the pipeline.

Abstract: The invention relates to particular burners, and e.g. to a burner comprising a central main fuel lance, a pilot fuel conduit, a main oxidant conduit, an auxiliary oxidant conduit, and optionally a secondary fuel conduit, which are arranged in a particular and advantageous way to surround each other at least in their downstream sections. The invention further relates to furnaces including the burners and methods of operating the burners. Among others, the burners of the present invention allow a particularly advantageous way of including a pilot burner as an integral part of the main burner to ignite liquid fuel flame in a cold furnace. If required, the pilot flame can assist in extending the flammability limit or operating range of the liquid fuel burner.

Abstract: The invention relates to particular burners, particularly to non-premixed or partially-premixed dual-fue burners with flexibility to change the heat input from the two fuels. Accordingly, said burners may be used in applications that needs operation of a burner in both single-fuel, and/or duel-fuel mode depending on furnace operation needs. The invention further relates to furnaces including the burners and methods of operating the burners.

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: Processes and systems for glass making can utilize heat recovery to improve operational efficiency and flexibility of operation to provide improved yield, higher quality, or more consistent quality glass, and/or other efficiencies. Some embodiments can utilize adjustments in burner operation to account for different manufacturing conditions to provide improved quality of fabricated glass to provide improved yields of glass with a more efficient utilization of heat, which can improve the environmental impact associated with the manufacturing process in addition to improving the operational efficiency and flexibility of the glass manufacturing process.

Abstract: A method comprising reducing the pressure of a carbon dioxide injection stream with a first pressure reducer having a depth and producing a reduced pressure carbon dioxide stream; reducing the pressure of the reduced pressure carbon dioxide stream with a second pressure reducer positioned at a lower depth than the first pressure reducer to produce a further reduced pressure carbon dioxide stream; and injecting the further reduced pressure carbon dioxide stream into a reservoir having a depth; wherein the pressure of the carbon dioxide stream at the depth of the first pressure reducer is greater than a bubble point pressure of the carbon dioxide injection stream at the depth of the first pressure reducer; wherein the pressure of the further reduced pressure carbon dioxide stream at the depth of the reservoir is less than a minimum fracture pressure of the reservoir at the depth of the reservoir.

Abstract: An adsorber for utilization in purification systems for cryogenic fluid processing can include a first layer of adsorbent material and a second layer of adsorbent material within a bed of adsorbent material within the adsorber. The first layer can include alumina or other water removal adsorbent material while the second layer can include NaMSX or other suitable molecular sieve adsorbent material. The first layer can be sized to be substantially smaller than the second layer to facilitate a pre-selected ratio of water adsorption to molecular sieve adsorption so that water can break through the first layer to the second layer during purification operations while the volume of the adsorber can be provided in a much smaller size with much less adsorbent material utilized in the bed as compared to conventional designs. Embodiments can provide an increased purification operational capacity with reduced need for adsorbent material.

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: Recovering xenon and/or krypton from a feed gas can include utilization of a purge stream from a separation column positioned and configured to output at least one stream of fluid that is substantially nitrogen and at least one stream of fluid that is substantially oxygen. The purge stream can be split so that a first portion of the purge stream is fed as a liquid adjacent to a top of a purge treatment column and a second portion of the purge stream can be fed to a heat exchanger for superheating the second portion to feed a superheated vapor at or adjacent to a bottom of the purge treatment column. The purge treatment column can output a liquid stream that has a relatively high concentration of Xe and/or Kr therein as a feed stream for an Xe and/or Kr recovery system.
