The invention relates to a method and apparatus to carry out the method
for extracting petroleum distillate products from alcohol. The inventive
method capitalizes on the discovered property that petroleum distillates,
such as xylene and limonene, can be dissociated from their tight
molecular interaction with alcohol by their higher affinity for water.
The method also capitalizes on the discovered property that limonene, in
the presence of water, forms terpin hydrate, forming particles that can
be removed by filtration. Other, non-limonene petroleum distillates, once
dissociated from alcohol, can be removed by distillation.
