摘要:
The invention relates to a corrugated criss-crossing packing structure for installations that transfer material and/or heat between a gas phase and a liquid phase, comprising a first surface (10), called the primary surface, having a number of parallel channels (11). According to the invention, this structure has a second surface (20), called the secondary surface, comprised of a number of secondary packing elements (21, 31), each secondary packing element being placed inside a channel (11) of said primary surface (10) and being formed separately from the first surface. The invention is for use in cryogenic distillation.
摘要:
A packing body is formed from a sheet of foldable material by forming a first row of panels with first fold lines between adjacent panels, forming a second row of panels having a second fold line inducing a common fold line with an edge of at least one panel from the first row, the common fold line being substantially perpendicular to the first fold lines, and bending the panels in the first row along the first fold lines until the panels are positioned in a stack and bending the panels in the second row into a second stack and folding them along the common fold line above or below the first stack.
摘要:
An improved packing body is formed from a strip divided into segments along fold lines. Segments along one side of a medial segment are alternately folded along the fold lines into a stack on the top surface of the medial segment. Segments on the other side of the medial segment are then folded along the fold lines into a stack on the bottom surface of the medial segments. Side segments hingedly connected to the medial or end segments can be folded along the side edges of the stack. Baffle elements can project from the surface of the strip at an angle to the longitudinal axis of the packing body. Tapered strips with a large medial segment disposed to the interior can be folded into a shape approaching spherical.

Shaped bodies having catalytic properties which can be obtained by a process comprising the steps: a) production of a shaped body by means of a powder-based rapid prototyping process, b) if appropriate, a heat treatment of the shaped body, c) if appropriate, application of at least one catalytically active component to the shaped body, d) if appropriate, a further heat treatment, where steps b), c) and/or d) can be carried out a number of times, are used as reactor internals in heterogeneously catalyzed chemical reactions.
摘要:
A fluid reactor for facilitating mixing and/or chemical reaction and including an elongated cylindrical flow chamber having a first for receiving a flow of a first fluid, a second flow inlet through which a relatively low mass flow of a second fluid may be admitted to the chamber; and a cone-pi element disposed downstream of the second flow inlet and having an upstream conical portion with a leading apex generally facing the first flow inlet, an intervening cylindrical portion, and a downstream conical portion with a trailing apex generally facing the flow outlet, the cone-pi element being operable to produce cavitation and/or vortical flow within the flow stream to effectuate mixing and/or chemical interaction of the first fluid and the second fluid, and to deliver a mixed and/or reacted fluid from the flow outlet. The reactor may also include a catalytic component disposed within the chamber between the cone-pi element and the flow outlet for further influencing the interaction between the first fluid and the second fluid prior to its exit through the flow outlet.
摘要:
A catalyst support is formed of a monolith having corrugated metal leaves. The corrugations of each leaf are oblique relative to the edges of the leaf. Each leaf extends from an interior region to an exterior region, and has corrugations that are non-parallel to the corrugations in an adjacent leaf. Each leaf also includes slits, and is coated with a suitable catalyst. A set of monoliths, made as described above, are stacked within a cylindrical pipe. The corrugations define gas flow channels, which enable heat applied to the exterior of the pipe to travel to the center of the monolith, and back to the outside. The support of the present invention thus facilitates heat transfer to essentially all regions of the monolith. The invention also inherently overcomes the problem associated with thermal mismatch between the metal pipe and a ceramic catalyst material.

摘要:
The invention relates to moulded bodies having catalytic properties, obtained due to a method that comprises the following said steps: a) a moulded body is produced by means of a powder-based rapid-prototyping-method, b) said moulded body is optionally heat-treated, c) at least one catalytically active component is optionally applied to the moulded body, d) said moulded body is optionally subjected to another heat-treatment. The steps b, c) and/or d) can be performed several times. Said moulded bodies are used as reactor fittings in heterogeneously catalyzed chemical reactions.
