摘要:
A method for controlling the magnitude of mechanical forces exerted by a solid ammonia storage material on walls of a container : determining a mechanical-strength limit of the container in terms of a hydraulic pressure P LIMIT or force F LIMIT under which the walls of container do not undergo plastic deformation, or deformation of more than 200% of deformation at the yield point; using a correlation between a temperature T SAT for the ammonia saturation/resaturation process, and the hydraulic pressure P MAT , or F MAT generated by the storage material during saturation/resaturation, to identify a minimum temperature T SATMIN where P MAT , or F MAT is kept below the limit for the mechanical strength by carrying out the saturation/resaturation process at the temperature T SAT fulfilling the condition of T SAT ‰¥ T SATMIN .

摘要:
A method and apparatus for removing water from compressed air is disclosed. The method includes the steps of passing a stream of compressed air through a pressure swing adsorption (PSA) dryer. The dryer includes at least one vessel containing a desiccant material bound into pieces, for example tubes, using a polymer binder. The PSA dryer also has a control system for controlling the flow of the compressed air and switching between drying and purging modes. In particular the vessel and desiccant material contained therein are sized to produce a dew point suppression of less than 50° C.

L'invention a pour objet un procédé de captation d'impuretés soufrées, telles que l'H 2 S et/ou le COS et/ou le CS 2 , présentes dans des charges gazeuses comprenant de l'H 2 et/ou du CO, comprenant : a. la désulfuration par mise en contact, à une température allant de 20 à 450°C, de la charge à traiter avec une masse de captation renfermant une phase active comprenant : - au moins un oxyde d'au moins un métal (I) du groupe VIIb, VIIIb, Ib, ou IIb, et - au moins un oxyde d'au moins un métal (II) choisi dans le groupe constitué par Cr, Mo, W, et les terres rares tels que Pr, Nd, Ce,
le rapport molaire entre le métal (I) et le métal (II) allant de 0,6 à 20, b. optionnellement, l'inertage de la masse de captation sulfurée, c. la régénération par voie oxydante de ladite masse de captation, d. optionnellement, l'inertage de la masse de captation régénérée, et e. la désulfuration par mise en contact, à une température allant de 20 à 400°C, de la charge à traiter avec ladite masse de captation régénérée et inertée,
caractérisé en ce que la masse de captation est régénérée à une température allant de 20 à 600°C, de préférence allant de 250 à 550°C, et plus préférentiellement allant de 300 à 480°C.
摘要:
The invention provides a water gas shift process comprising a reaction stage. The reaction stage comprises (a) providing a gas mixture comprising CO, H2O and an acid gas component to a reactor containing an adsorbent, and (b) subjecting the gas mixture to water gas shift reaction conditions to perform the water gas shift reaction. The adsorbent comprises an alkali promoted alumina based material. The acid gas component comprises H2S.
