Abstract: In a cooled axial/radial flow converter, in which process gas passes from an outer annulus via a catalyst bed to an inner centre 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 centre 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.

Abstract: In a process for co-production of ammonia and methanol, the outlet stream from the reformer is split into two parts, one of which is subjected to shift, carbon dioxide removal, methanation, compression and ammonia synthesis, while the other part is compressed and fed to a once-through methanol synthesis section. Methanol is withdrawn from the methanol synthesis section, and the remaining effluent from said section is divided into two streams comprising hydrogen, of which one is fed to the shift section, while the other is recycled to the desulfurization unit. This way a favourable co-production method is obtained because recycle hydrogen for the desulfurization is provided, and furthermore a compression step is avoided.
