Description of the Related Art Conventionally, when a volatile oil-containing waste liquid or waste oil has a small oil content, the waste is consigned to an industrial waste trader and treated by combustion. Toxic substances such as dioxin are also generated from methane, which has become a problem worldwide. Also,
Illegal dumping leaves no end, polluting groundwater and destroying the ozone layer. On the other hand, these alternatives have been taken up as a social problem as a global warming promoting substance. or,
A large amount of wastewater containing relatively high oil content is separated and the oil is treated by distillation under reduced pressure or atmospheric pressure. Regarding the treatment of chemical substances, the problem of remaining harmful substances in the residue is always left in the processing within the regulation value. Finally, it is burnt and treated as industrial waste while containing harmful substances. This is because volatile oil remains in the still space at the end of distillation. On the other hand, steam distillation is used to produce essential oils from plants and the like. The use of distillation stabilizers or distillate stabilizers in the process is not yet known.
