Summary

Following on earlier versions, the treatment of dispersion and mixing in the reactors has been considerably elaborated. In particular finite rates of turbulent and molecular diffusion are allowed for. In this interim account, predictions of the urea formation from this model applied to the conditions of the Blackley Laboratory rig are compared with the experimental results which were reported after the model predictions. A simplified treatment of the effect of agitation and injection on the side reactions (notably to urea) is appended.
