p mix the co solvent can be propane ethane butane propylene 2 methylpropane dimethylpropane propadiene diemethylether chlorodifluromethane diflouroromethane and methylfluoride in addition to propane organic solvents such as propanol and supercritical ethane can also be used the cyclonic vacuum distillation separation apparatus comprises an outer shell with inner upper central reactor located large cyclonic processing cone 7 upstream to a secondary parallel series of smaller processing cyclonic cones 8 surrounding and downstream of the larger central cone a third cyclonic separating cone is located downstream of the second series and optionally includes at least one third sized single cyclonic cone not pictured the cyclonic cone system may include a heat jacketed cone which serves as an advanced art invention to the wiped film evaporator thin film and short path systems due to its high processing speed of 100 000 g 39 s of gravitational force or higher no moving parts and thorough filtration efficiency the separation efficiency of each of the three successive cyclonic processing steps is controlled by the size of that particular series diameter of the inlet and outlet the cyclone 39 s diameter body length taper angle and the depth of the cylindrical inlet at the top of the cyclone the feed stream is progressively purified within each series of cyclones with each.
