Isothermal chemical reactor with plate heat exchanger

摘要

A chemical isothermal reactor (1) with internal plate heat exchanger (10) having heat-exchange radial plates (11), and radial ducts (14, 15) parallel to sides (13i, 13s) of the plates (11) for distributing and collecting a heat exchange fluid, said radial ducts having a portion with a smaller cross section near the inner converging ends (14c, 15c).

主权项

1. A chemical isothermal reactor comprising:
at least one plate heat exchanger with a substantially annular structure, said heat exchanger comprising a plurality of radially-arranged heat-exchange plates, one set of first radial ducts for feeding a heat exchange fluid to internal passage(s) of said plates and one set of second radial ducts for collecting said heat exchange fluid from internal passage(s) of said plates, said radial ducts being aligned with radial sides of the plates, said radial ducts having opposite ends, wherein the ends of said radial ducts facing a central axis of the reactor are closer to one another (converging ends) with respect to the opposite ends of the radial ducts, which are more spaced apart to one another (diverging ends), and, wherein the converging ends of radial ducts of said sets of first and second radial ducts for feeding and for collecting said heat exchange fluid have a reduced cross section compared to their respective diverging ends, or the converging ends of radial ducts of said second set of radial ducts for collecting said heat exchange fluid have a reduced cross section compared to their respective diverging ends while radial ducts of said set of first radial ducts for feeding said heat exchange fluid have a constant cross-section.
