Method for carrying out chemical reactions in pseudo-isothermal conditions

Abstract

A method for carrying out chemical reactions in so-called pseudo-isothermal conditions and in a predetermined reaction environment, for example a catalytic bed, comprises the step of arranging in the reaction environment at least one heat exchanger crossed by an operating fluid along a main direction.

1 . Method for carrying out chemical reactions in so-called pseudo-isothermal conditions and in a predetermined reaction environment, for example a catalytic bed, comprising the step of arranging in said environment at least one heat exchanger ( 1 ) crossed by an operating fluid along a main direction, characterized in that the same flow of operating fluid is fed in many points along said main direction.  
     
     
         2 . Heat exchanger for carrying out the method according to  claim 1 , comprising two metallic plates ( 2 ,  3 ) of small thickness, substantially flat, juxtaposed and joined in a predetermined spaced relationship through a perimetric welding ( 4 ) defining, between them, a chamber ( 5 ), in fluid communication with the outside through a fluid inlet fitting ( 6 ) and a fluid outlet fitting ( 7 ) positioned on respective opposite short sides ( 8   a,    8   b ), characterized in that it comprises divider baffles ( 12 ), inside said chamber ( 5 ), defining in said exchanger ( 1 ) a distribution channel ( 10 ) and a heat exchange chamber ( 9 ).  
     
     
         3 . Heat exchanger according to  claim 2 , characterized in that said divider baffles ( 12 ) are formed in the exchanger ( 1 ) through plastic deformation of the metallic plates ( 2 ,  3 ).
