摘要:
A solar thermochemical processing system is disclosed. The system includes a first unit operation for receiving concentrated solar energy. Heat from the solar energy is used to drive the first unit operation. The first unit operation also receives a first set of reactants and produces a first set of products. A second unit operation receives the first set of products from the first unit operation and produces a second set of products. A third unit operation receives heat from the second unit operation to produce a portion of the first set of reactants.
摘要:
Systems and methods are provided for using a reverse-flew reactor (or another reactor with flows in opposing directions at different parts of a process cycle) as part of a reaction system for production of ammonia and/or urea. Using a reverse flow reactor as part of an ammonia production process can provide a variety of advantages, including direct heating of the reaction environment, and simplified generation of multiple high-purity reagent streams for ammonia and/or urea synthesis.
摘要:
A method for improving efficiency of an existing ammonia synthesis gas plant or a new ammonia synthesis gas plant by establishing a combination of secondary steam reforming using oxygen from electrolysis of water for the production of ammonia synthesis gas.
摘要:
A process and a related equipment for making ammonia make-up synthesis gas are disclosed, where: a hydrocarbon feedstock is reformed obtaining a raw ammonia make-up syngas stream; said raw syngas is purified in a cryogenic purification section refrigerated by a nitrogen-rich stream produced in an air separation unit; the nitrogen-rich stream at output of said cryogenic section is further used for adjusting the hydrogen/nitrogen ratio of the purified make-up syngas; an oxygen-rich stream is also produced in said air separation unit and is fed to the reforming section.
摘要:
Disclosed is a process for the production of ammonia comprising a step wherein synthesis gas is formed by catalytic partial oxidation. Also disclosed is a process of producing urea, wherein ammonia is formed in a process involving a step of catalytic partial oxidation, and carbon dioxide formed in the same process is reacted with said ammonia so as to form urea.
摘要:
Method for the production of ammonia, and optionally urea, from a flue gas effluent from an oxy-fired process, wherein the production of ammonia and optionally urea includes a net power production. Also provided is a method to effect cooling in an oxy-fired process with air separation unit exit gases utilizing either closed or open cooling loop cycles.
摘要:
A hydrogen generator includes a reformer configured to cause a reforming reaction using a material and steam to generate a hydrogen-containing gas; a shift converter configured to reduce CO in the hydrogen-containing gas by a shift reaction; an evaporator provided adjacent to the shift converter so as to perform heat exchange with an upstream side of the shift converter and configured to evaporate water; and a hydro-desulfurizer provided adjacent to the shift converter so as to perform heat exchange with a downstream side of the shift converter and configured to remove a sulfur compound in the material by a hydrodesulfurization reaction.
摘要:
A hydrogen generation device of the present invention comprises a first path (31) used to supply a raw material to a reformer (1) through at least a first desulfurization unit (2); a second path (32) used to supply the raw material to the reformer (1) through only the second desulfurization unit (3); a switch unit (6); a flow control unit (8) which selectively enables or inhibits a flow of the hydrogen-containing gas generated in the reformer 1 toward the second desulfurization unit (3); and a controller (12) configured to execute processing in such a manner that in at least either a time point before generation of the hydrogen-containing gas is stopped, or start-up, the switch unit 6 performs switching to select the first path (31), and the flow control unit (8) enables the flow of the hydrogen-containing gas, while the reformer 1 is generating the hydrogen-containing gas.
摘要:
A system and method for advancing an implant into a surgical incision. The implant is placed into a compression sleeve. The compression sleeve has a first open end, a second open end, a first stage of a first length, and a second stage of a second length. The cross-sectional profile of the first stage is larger than the cross-sectional profile of the second stage. The implant is inserted into the first stage of the compression sleeve through the open first end. The compression sleeve is compressed to advance the pliable prosthetic implant at least partially into the second stage of the compression sleeve. The open second end of the compression sleeve is directed into a surgical incision. The compression sleeve is further compressed to advance the pliable prosthetic implant through the second stage, through the open second end, and into the surgical incision.
