Abstract: The present invention concerns a device and a process for the storage and restitution of heat which comprises at least two concentric heat storage volumes (TES1, TES2, TES3). The walls (2) delimiting these storage volumes are configured in a manner such that the thickness of the wall delimiting the central storage volume is greater than the thickness of the wall delimiting the peripheral storage volume.

Abstract: The present invention relates to a compact connector design with an internal locking ring (11). The connector according to the invention comprises a locking ring (11) allowing bayonet type connection on either side with two riser sections. Furthermore, the connector comprises at least one removable pin (12) for translationally blocking locking ring (11), notably upon locking and unlocking.

Abstract: A reactor (1) delimited by a shell (2) extending along a vertical axis: a vessel provided with a reaction zone (10) containing a bed of catalyst; at least one inlet (3) for a gaseous feed; at least one outlet (4) for a gaseous effluent produced in the reaction zone (10), inside the reaction zone (10), at least two tubes extending substantially vertically over the height of the reaction zone, the tubes being permeable to a gas phase and impermeable to catalyst, each tube (9) having an upper end (11) in communication with the inlet for the feed or with the outlet means for an effluent and an opposed second end (12), the tubes (9, 24) supported at their upper end by a first plate (14) which is secured to the shell (2), via a connection assembly providing a pivot and slide type connection.

Abstract: The present invention describes a type of radial bed reactor which can allow a small quantity of catalyst to be used. Application to a regenerative reforming process reactor.

Abstract: The invention is a container (200) for a system for storing and restoring heat, comprising a vessel including means for injecting and withdrawing a gas to be cooled or reheated. The vessel is limited by a first jacket formed from concrete (203) surrounded by a thermally insulating layer (206), which is surrounded by a steel shell (204). The vessel comprises at least two modules formed from concrete (210) located one above the other and centered to form a first jacket from concrete (203). Each module formed from concrete comprises a volume limited by a side wall formed from concrete (211) and a perforated base formed from concrete (205). The volume contains a fixed bed of particles of a material for the storage and restitution of heat (207).

Abstract: The invention relates to a container (200) for a heat storage and restitution system, comprising a vessel in which a gas is circulating in order to be cooled or heated. The vessel is limited by a first jacket formed from concrete (203) surrounded by a thermally insulating layer (206), which is itself surrounded by a steel shell (204). The vessel comprises at least two modules (210), each comprising a double wall formed from concrete and a perforated base (205) limiting at least two volumes (217 and 216) which are each capable of containing a fixed bed of particles of a material for storage and restitution of heat (207). The modules are disposed one above the other in a centered manner such that the double wall formed from concrete forms the first jacket formed from concrete (203) and a second jacket formed from concrete (215).

Abstract: The present invention concerns a radial bed reactor comprising a vessel provided with a reaction zone with a moving catalyst bed. The reactor further comprises, inside the reaction zone: at least two feed distribution tubes, each having a first end in communication with the feed inlet means and a second, closed end, the distribution tubes extending in a substantially vertical manner and being designed to allow the feed to pass through the reaction zone and to retain the catalysts; and at least two effluent collection tubes, each having a first end (14) communicating with the effluent outlet means and a second, closed end (15), the collection tubes extending in a substantially vertical manner and being designed to allow effluent to pass through the collection tube and to retain the catalysts.
