SOLVENT REFINING
Resource-saving recycling
Resource-conservation, life-cycle and waste management can all be combined in a single essential concept: Recycling. That is what Christoph Dürr GmbH specializes in.
We use the distillation separation process for solvent refining. In this process, contaminated organic substances are physically separated on the basis of different boiling temperatures. You can read about the exact chemical-physical process here.
The contamination remains in the system and is then disposed of by us. The average recoverable yield is about 80 percent of the original delivery quantity.
Using the technology in our own laboratory, we are able to guarantee our customers the consistent and excellent quality of our purified products. Gas chromatographic analyses to determine the purity and the ingredients contribute to continuous quality improvement.
A RANGE OF POSSIBILITIES
When processing your orders, we offer you various options for processing.
We can distill your goods through subcontracting – you get your goods back after thermal processing. Refining is possible from as little as 2,000 liters thanks to our reactors.
We can also offer purchased goods from our inventory in your required quality in addition to your refined materials. You will receive an analysis in advance with the important parameters of the distillate.
Another option is immediate exchange: We deliver the required amount of distillate or virgin substances when picking up the old substance. This ensures that you are always supplied with substances and your storage capacity is not exhausted.
If you cannot use your solvents after thermal cleaning in your operating processes, we will gladly take over your old substances at a reasonable price.
VERIFICATION AND SOLUTIONS
Based on our many years of experience as a certified disposal specialist, we can advise and support you quickly and professionaly in accordance with the statutory requirements of waste legislation.
When processing your orders, you automatically receive the necessary transport documents and corresponding proof of disposal in a prioritized procedure.
We have approved collective disposal documents for smaller quantities. We are also happy to take over your labeling and loading obligations according to the Life-Cycle and Waste Management Act and the ADR.
FLEXIBILITY IS OUR STRENGTH
Thanks to our own fleet of vehicles, we are always flexible and can accept your orders quickly and reliably. When transporting your new and old substances we offer the option of general-cargo or tanker transport.
