Abstract
Official abstract text for this publication.
In a cooled axial/radial flow converter, in which process gas passes from an outer annulus via a catalyst bed to an inner center tube, the catalyst bed is divided into identical modules stacked on top of each other. The process gas reaches the catalyst through openings facing the outer annulus, passes axially down the catalyst bed of each module, leaves the module through collectors in the bottom thereof, and flows to the center tube. The catalyst bed is cooled by cooling panels, in which the process gas is pre-heated to the reaction temperature, while at the same time the heat of reaction is partly removed from the catalyst bed. The converter is especially suitable as ammonia converter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cooled axial/radial flow converter, in which process gas passes from an outer annulus via a catalyst bed to an inner centre tube, wherein the catalyst bed is divided into a number of identical modules stacked on top of each other, the feed flow of process gas reaches the catalyst through openings facing the outer annulus, passes axially down the catalyst bed of each module, leaves the module through collectors in the bottom thereof, and flows to the centre tube, and the catalyst bed is cooled by cooling panels, in which the process gas is pre-heated to the reaction temperature, while at the same time the heat of reaction is partly removed from the catalyst bed. 2. Converter according to claim 1 , which is used as an ammonia converter. 3. Converter according to claim 1 , wherein the module is an axial flow canister comprising a number of small exchanger plates and a number of main exchanger plates. 4. Converter according to claim 3 , wherein cooling of the catalyst is achieved by insertion of vertical cooling plates installed radially in each canister.
