solvent distillation equipment is distillation machines that allow the recycling and
the reuse of degreasing and washing solvent. Through use of the solvent distillation
machines, they separate the contaminants (resins, polymers, pigments, paints, oils, etc.) from the original solvent.
The distillation of the solvent is accomplished by a peripheral heating jacket filled with diathermic oil, heated by an electrical element.
This means that during the solvent distillation
process, the heating source is never in contact with
the solvent being distilled. The
solvent vapors are then conveyed to a condenser, cooled by air or water. The
distilled solvent is collected in a tank, for its reuse.
For solvent distillation, vacuum systems can be attached to
the distillation machine to distill
solvent while under a vacuum. Utilizing
vacuum distillation equipment, the boiling point of the solvent is lowered, decreasing the temperature necessary for distillation
of the solvent.
Specially designed doctor blades can mix the waste
solvent being distilled so that the discharge of the distillation system is a
powder or a flake. Without the doctor blades, the
solvent distillation machine would reduce the waste to a thick syrup or paste. If you distill to a powder or a flake, often the result is
that the discharge can be disposed of as a non-hazardous material. Obviously, if your distillation waste is a thick syrup, you may have to dispose of it as a hazardous
material. Only the dry waste can pass the T.C.L.P. tests required by the Environmental Protection Agency.
