tube bundle reactor

Abstract

The invention relates to a tube bundle reactor for carrying out catalytic gas phase reactions with a reactor tube bundle which is filled with a catalyst during operation and through which reaction gases flow, tube bottoms on the gas inflow side and on the gas outflow side , the reactor shell (which surrounds the tube bundle and is sealedly connected with the bottom of the tube to construct a shell cavity with the bottom of the tube, in the shell cavity, the reaction tube is washed around by the heat carrier during operation), and the bottom of the tube on the gas outflow side has a tube bundle Occupying at least one first tube bottom section and having at least one second tube bottom section without tube bundles, there is at least one first gas outflow chamber section (which is aligned with the first tube bottom section) in the gas outflow chamber And there is at least one second gas outflow chamber section (which is aligned with the second pipe bottom section and has a dead space), and with at least one flow guiding device arranged in the second gas outflow chamber section, which is configured to From the first gas outflow chamber section, it directs a partial flow of the reaction gas flowing out of the reaction tube into the dead space.

Description

technical field [0001] The invention relates to a tube bundle reactor according to the preamble of claim 1 . Background technique [0002] Such tube bundle reactors are known, for example, from documents US 7,554,836 B2 and WO 2008 / 009466 A1. In these documents it is proposed to arrange the extrusion body in a section of the gas outflow chamber that is aligned with the tube-free or tube-bundle-free region in the shell chamber. The squeeze body prevents the reaction gas flowing out of the reaction tube from flowing there into a dead space of the gas outflow chamber next to the main flow of reaction gas. [0003] Within the scope of the present application, the term "dead space" is understood to mean the section of the gas outflow chamber which lies next to the flow path which would be occupied by the reaction gas flowing out of the reaction tube without flow guides, and in which dead space In that case there are undefined flow conditions and the reaction gas therefore stays...

[0003] Within the scope of the present application, the term "dead space" is understood to mean the section of the gas outflow chamber which lies next to the flow path which would be occupied by the reaction gas flowing out of the reaction tube without flow guides, and in which dead space Then there are undefined flow conditions and the reaction gases therefore stay there longer, so that undesired side reactions can result as a result
