Abstract
Pseudo-isothermal chemical reactor (1) for catalytic reactions with a vertical axis, comprising a substantially cylindrical shell (2), Closed at the opposite ends by upper (4) and lower (3) bottoms respectively, a reaction zone (8) in which a catalytic bed (11) and a plurality of flat, boxed, plate-shaped heat exchangers (12), having the shape of a parallelepiped and having long sides parallel to said vertical axis and short sides perpendicular to it, situated in said reaction zone and supported in an arrangement on parallel cords at a predetermined distance.
Claims2
Axial pseudo-isothermal chemical reactor (1), comprising a substantially cylindrical shell (2), with vertical axis (A-A), closed at the opposite ends by upper (4) and lower (3) bottom respectively, a reaction zone (8), defined in said shell (2) and in which a catalytic bed (11) and a plurality of flat, boxed, plate-shaped heat exchangers (12), having the shape of a parallelepiped and having vertical long sides (20) and short sides (21) parallel to a same diameter of the shell (2), are supported, characterized in that said exchangers (12) are all identical and in that their short sides (21) have the ends arranged on imaginary cylindrical surfaces (22, 23, 24, 25, 26, 27) having the same radius as the inner radius of the shell (2) and centers all arranged on a same diameter of the shell (2), wherein at least two of said exchangers (12) are arranged on same imaginary cylindrical surface of said imaginary cylindrical surfaces (22, 23, 24, 25, 26, 27), said-plurality of heat exchangers (12) centrally defining an axial manhole passage (19)
