Reactor panel for catalytic processes

Abstract

Modular reactor panel (1) for catalytic processes, comprising a feed header (5), a product header (7) and adjacent channels (3), each channel (3) having a length, running from an entrance end to an exit end, and wherein the entrance ends are directly connected to and open into the feed header (5) and the exit ends are directly connected to and open into the product header (7) and wherein the feedheader (5) has at least one connection (9) to a feed line (51) and the product header (7) has at least one connection to a product line (55) and wherein part (21) of at least one of the feed header (5) and the product header (7) is detachable giving access to the channel ends and reactor comprising a housing (47) containing one or more of said reactor panels (1, 29), the reactor further comprising a feed line (51) and a product line (55), the panels (29) being connected to the feed line (51) and to product line (55).

Description

technical field [0001] The invention relates to a reactor panel for a catalytic process, a reactor comprising such a panel and the use of said reactor for carrying out heterogeneously catalyzed exothermic or endothermic reactions. Background technique [0002] Reactor types and industrial applications of catalytic reactors are described extensively by Klaus Dieter Henkel et al. in Ullmann Encyclopedia; ReactorTypes pp. 1-33 (2005 Wiley VCH Verlag Weinheim). [0003] Heterogeneous catalytic methods play an important role in the chemical technologies used to generate many key products and intermediates. In these processes, fluid reactants, especially gases, liquids and supercritical fluids, are reacted in the presence of a solid catalyst, which may be in the form of particles such as pellets or powders, or continuous matter such as coatings on reactor walls. layer. Suitable reactors for heterogeneously catalyzed processes include, for example, fixed bed reactors. Reactors w...

AI Technical Summary

Problems solved by technology

This almost always results in a non-optimal compromise between the number and diameter of the tubes

And adding more tubes makes it more complicated to achieve the desired heating / cooling flow regime

Also, the supplied ingredients don't seem to be evenly distributed in the various tubes

[0008] Another disadvantage is that the rigid connection to both headers causes mechanical stress and frequent mechanical failures of multi-tubular reactors due to thermal expansion of the tubes

This can lead to unwanted contact between reactant or product streams and heating / cooling medium streams and require production shutdowns and repairs

Other disadvantages are the complex header structures required for the separation process from the utility stream and the resulting high investment costs for multi-tubular reactors

In addition, uneven distribution of raw materials leads to blockage of tubes and self-propelled plugging effect of adjacent tubes

Another disadvantage is the lengthy process of filling the tube
