A solvent recycler is very simple in concept – dirty solvent goes in and clean solvent comes out. Solvent recycling is a very practical method for saving money and minimizing waste since solvent can be used indefinitely if contaminants are removed.
A solvent recycler is the machine that separates or removes contaminants from the original solvent. The processed solvent is then clean and able to be used again as if it is brand-new. This can be done indefinitely. Meanwhile, the contaminants can be easily packaged and discarded.
Using a solvent recycler not only saves the cost of purchasing replacement solvent but also lowers cost of waste disposal. Without being recovered through the recycling process, the chemicals would often require hazardous waste removal. By using a solvent recycler, the solvent itself can be reused and the contaminants, which would be a far smaller amount of material, can then be disposed of at a much lower cost. All of our solvent recyclers are certified to UL 2208 and ATEX II explosion-proof standards.
The Emission Estimation Technique Manual for Solvent Recycling cites a variety of methods for treating waste solvents, such as mechanical separation or vapor recovery/distillation. Mechanical separation only removes solid matter from the solvent.
At NexGen, our solvent recyclers use distillation for thorough results. Dirty solvent is either pumped in from a storage tank, drum, etc. or poured into the smaller machines from 5-gallon buckets. The machine heats the solvent until it vaporizes. At that point, the vapor enters a condenser where it is cooled until it returns to a liquid state and moves to the collection vessel. The contaminants stay in the boiling tank where it can be removed through a bag or drained into a collection vessel.
