A multi-bed catalytic converter ( 1 ) with inter-bed heat exchangers, comprising a plurality of superimposed catalytic beds and a common heat exchanger ( 5 ) which is shared between two or more consecutive catalytic beds, said common heat exchanger including heat exchange bodies such as a tube bundle ( 6 ), and a wall system ( 9, 10 ) to define a tube side and a shell side respectively, and the shell side comprising at least a first space ( 12 ) and a second space ( 13 ), wherein the first space ( 12 ) receives the product gas leaving the first of said consecutive beds, and the inter-cooled gas leaving said first space ( 12 ) is admitted in the second bed ( 3 - 3 ) for further conversion, and a sealing means ( 14 ) preventing a direct gas passage from said first space to said second space. |
