Distillation is the process of separating volatile from non-volatile components present in a mixture. The general process consists of evaporating the mixture and condensing the vapors back into a liquid.
Parsian Green Chemical Industries Co. solvent distillation units separate volatile solvents from non-volatile materials that have contaminated the solvent during some type of manufacturing process. The waste solvent temperature is raised to boiling point, vapors are separated in a mist separator and collected after condensed. Knowing that many solvents are heat sensitive e.g styrene monomer or have high boiling points, vacuum distillation may be needed.
The choice of which type of distillation to use depends upon (i) the purity that is needed in the recovered distillate(s) (solvents), and (ii) whether two or more volatile components exist in the mixture
In Simple and vaccum Distillation, the hot vapors travel directly from the boiling tank into the condenser where they are cooled and become liquid. Simple and vaccum distillation systems are frequently used to recover solvents from non-volatile material like;
1)acetone and styrene from fiberglass residue
2)methanol and acetone from parts washing
3)mineral spirits from paint and resin tank washing
4)Isopropyl alcohol from pharmaceutical waste
5)Toluene/THF from Pharmaceutical waste
6)paint thinner from paint and resin
