Summary

Two trains of methyl chloride chlorinators are currently in operation at Rocksavage Works. The chlorinators in one train (stream A) have internal diameters of 26 inches; the chlorinators in the other train (stream B have internal diameters of 32 inches. The second train works well, but the first train produces unacceptable quantities of soot and hexachloroethane. Experiments carried out on 1/9 linear scale models indicate that the different geometry is one cause, at least, of the different performances of the models and this conclusion holds over a large range of throughputs. The evidence for this view is summarised in this report.
