Analysis of the operation of experimental equipment for the continuous oxidation of paraffin wax

The following conclusions can be drawn from analysis of the results on the enlarged experimental installation at the Novokuibyshevsk Refinery.
Continuous oxidation of paraffin wax in a direct-flow multi-section column has a number of advantages over batchwise oxidation:>
the time required under industrial conditions to oxidize paraffin wax to the required depth (30–33% fatty acids) is reduced fourfold (4–4.5 h instead of 16–18h);
the yield of fatty acids per m3 of column per hour increases by a factor of 3.2;
under continuous oxidation conditions there is a considerable reduction in the molecular weight of the acids which is favourably reflected in their fractionalcomposition (yield of C7-C9 acids is 11.2% and C10-C16 acids 37.8% recalculated to 100%-purity).
During continuous oxidation there is greater possibility of varying the oxidation conditions and of controlling the temperature conditions, which is particularly important in processing paraffin wax of non-standard quality.
Volatile oxidation products can be trapped in the special cooler-absorber section of the apparatus. The yield of oxidized paraffin wax during continuous oxidation is 98.5% of the feedstock weight.
