Solvent Recovery
Seqens CUSTOM SPECIALTIES OFFERS A RANGE OF SOLVENT RECOVERY SOLUTIONS
Seqens Custom Specialties offers a complete solvent recovery solution. We have vast experience in recovering and recycling a wide range of streams and by-products from across the manufacturing sector.
What is solvent recovery?
Solvent recovery is the process of extracting useful materials from waste or by-product solvents generated during the manufacturing process. These chemicals can then be repurposed, reducing the need to produce new solvents, while eliminating a large amount of waste and removing potentially hazardous substances from what’s left.
There are quite a few methods of recovering solvents, including fractionation, azeotropic distillation, and extractive distillation. At Seqens Custom Specialties, our advanced technology, specialist expertise, and extensive asset base allows us to achieve a very high degree of efficiency in solvent recovery.

Benefits to your business
What Seqens Custom Specialties can offer your business?
If you are a by-product solvent producer, you can dispose of your spent solvent stream via thermal oxidation/landfill or by recovery.
Here at Seqens Custom Specialties, not only can we offer basic waste solvent recycling, but we can also offer you further options. With our toll recovery, your by-product streams and waste solvents will be purified and returned to you for reuse. Alternatively, we can take ownership of the waste and re-purpose them ourselves.
You will also benefit from our own strengths, which include:
- Operational and technical excellence: Our team are experts in their field and use the latest equipment.
- Agility: We can get your stream into the plant rapidly.
- Flexibility: Alongside our solvent recovery we react and distil, delivering higher purity, improved value, and sustainability credentials.
- On-time delivery of service and supply chain
- Market connectivity for valorisation of streams
- Location in the heart of chemical cluster
- Seveso III / COMAH sites offering abatement technology
Seqens Custom Specialties’ Solvent Recovery stems from a continuous collaboration with numerous industry leaders for the recovery of solvents and solvent by-products from:
- Industrial solvents users and manufacturers
- Pharmaceutical manufacturers
- Electronics industry
