Title:
MULTI-TUBULAR REACTOR AND MULTI-TUBULAR REACTOR DESIGN AND FABRICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/151108
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a multi-tubular reactor with which, when fabricating a substance with an exothermic or an endothermic reaction, it is possible to appropriately control the reaction such that forming of a hot spot or a cold spot is avoided. The present invention relates to a multi-tubular reactor, and a design and fabrication method thereof, said multi-tubular reactor (1) comprising a cylindrical shell (2), a plurality of reaction tubes (10) which are positioned within the shell, and a disk-and-donut baffle (5). The plurality of reaction tubes (10) are arrayed to form a triangular position. One or more of the plurality of reaction tubes (10) are temperature measurement reaction tubes whereupon thermometers (20) are disposed. In a cross-section face of the reactor (1) which is orthogonal to a central axis of the shell (2), a line (BL) which joins a central axis of the temperature measurement reaction tubes and the central axis of the shell, and a line (CL) which joins the central axis of the temperature measurement reaction tubes and a central axis of at least one adjacent reaction tube which is adjacent to the temperature measurement reaction tubes, form an angle of 0-15 degrees.
