✦ Synopsis

An alternative design for the industrial multitubular shell-side fixed-bed ammonia converter is presented. It can be run either under cocurrcnt or countercurrent cooling flow. The behaviour of these two alternatives is compared with that of the existing fully-autothermal co-or countercurrent designs. The comparison among the four cooling schemes is drawn by means of a heterogeneous two-dimensional mathematical model. The results indicate that the cocurrent alternative of the new design is capable of producing a significant increase in the ammonia yield. This higher value could also be obtained at lower maximum temperatures, which would lengthen the catalyst life.

The use of mixed axial and radial flows in a fixed-bed adiabatic reactor can lead to regions of flow "back-up" in the bed. These regions cause temperature hot-spots to appear, even under conditions where there are none for a purely radial flow. The hot-spots can be reduced by balancing axial and rad
