A substantial proportion of all domestic aviation accidents and fatalities that occur each year involve GA, which includes all aviation except commercial and military.

In continuous distillation, the source materials, vapors, and distillate are kept at a constant composition by carefully replenishing the source material and removing fractions from both vapor and liquid in the system. This results in a better control of the separation process.
A better way of separating liquids is with a centrifuge, which is a cylinder into which liquids, gasses or other substances are inserted and then spun extremely quickly. The high-speed spinning process forces the different substances -- in this case, the liquids -- to separate according to density.
