equipment is used for distillation of solvent such as acetone,
xylene, toluene, and others. Solvent recycling allows you to close loop your waste
streams for inks, solvents, paints, or most any wash solution.
Distillation equipment is available for manual operation and for automatic
operation. With distillation equipment, your solvent waste stream is
solvent distillation equipment are solvent recycling / solvent recovery machines that allow the recycling and
the reuse of degreasing and washing solvents. Through use of the solvent distillation
machines, they separate the contaminants (resins, polymers, pigments, paints, oils, etc.) from the original solvent.
The solvent recycling is accomplished by a peripheral heating jacket filled with diathermic oil, heated by an electrical element. 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 systems and solvent recycling, vacuum systems can be attached to
the distillation equipment 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. For Acetone distillation, you would
not want to use a vacuum system because the boiling
point of acetone is so low that vacuum system would
not allow for proper condensing of the acetone
vapor. Many "safety solvents" have a high
boiling point and to reclaim a safety solvent,
vacuum distillation is often required.
Specially designed doctor blades can mix the waste
solvent in the distillation system 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
from solvent recycling is a thick syrup, you may have to dispose of it as a hazardous
material. Only a dry solvent waste can pass the T.C.L.P. tests required by the Environmental Protection Agency.
