TURNING WASTE STREAM INTO VALUABLE PRODUCT
The solvent regeneration business requires both maximum flexibility and high process efficiency. Our multi-purpose plants are specifically designed to process a wide range of solvents and solvent mixtures, enabling efficient dehydration, high solvent recovery and low energy consumption. The result is greater operational flexibility, improved profitability and a more sustainable regeneration process.
Designed for maximum flexibility
As a solvent regeneration service provider, you have to deal with constantly changing composition and purity requirements. Our multi-purpose plants are specifically designed to meet this challenge.
- Wide solvent compatibility: Our systems are compatible with a wide range of organic solvents and common thinner mixtures.
- Flexible purity targets: The plants reliably achieve a target purity below 1% water and down to 0.1% for high-purity requirements.
- Guaranteed quality: Batch operation allows product purity to be controlled precisely by adjusting the batch time, enabling you to meet different customer specifications with a single plant.
Recovering value instead of destroying it
Spent solvents often contain valuable components that are lost when they are sent for incineration while generating significant CO₂ emissions. Our pervaporation and hybrid technologies provide an energy-efficient alternative by recovering and regenerating solvents for reuse.
For solvent regeneration companies, this translates into lower energy consumption, reduced disposal costs and higher value creation from existing process streams. The result is a more sustainable operation with improved economic performance.
Engineered for challenging feed streams
Spent solvents are rarely clean. Our regeneration systems are specifically engineered to handle complex and variable feed streams with reliable, consistent performance.
- Pre-treatment of contaminated streams: When required, an upstream evaporation step safely removes salts or active pharmaceutical ingredients (APIs) and other non-volatile impurities before membrane treatment.
- Proven membrane stability: We carry out laboratory testing in advance using your representative process samples.
- Designed for safe operation: Our systems are designed in accordance with the ATEX Directive and the Pressure Equipment Directive (PED), ensuring safe, reliable operation in demanding industrial environments.
Frequently asked questions
What does "multi-purpose" mean for DeltaMem plants?
“Multi-purpose” means that the systems are designed to dehydrate a wide range of organic solvents and solvent mixtures within a single system. This flexibility is particularly valuable for solvent regeneration companies handling constantly changing feed streams, enabling them to meet diverse customer requirements without the need for dedicated plants for each application.
Does DeltaMem supply standard plants for solvent regeneration?
Yes. In addition to customised large-scale plants, we offer a cost-effective standard unit for batch pervaporation. Designed for processing up to 5 m³ (5,000 litres) of wet solvent per day, it offers a fast and economical entry into professional solvent processing.
Does pervaporation require chemical additives?
No. DeltaMem’s pervaporation technology dehydrates solvents through a purely physical membrane-based process and does not require chemical additives or entrainers. In contrast to distillation, which often requires a third component (entrainer) to separate certain mixtures, this simplifies the process, reduces the risk of product contamination and helps maintain high product purity.
How does DeltaMem ensure that the plant performs effectively for specific solvent mixtures?
Every project begins with comprehensive laboratory testing in our test centre. Using representative samples of your process stream, we verify membrane compatibility, long-term stability and separation performance under realistic operating conditions. We also provide a detailed analysis of the regenerated solvent to confirm that the required product quality can be achieved. The resulting process data forms the basis for our plant design, reducing technical risk and ensuring reliable industrial performance.
How does DeltaMem ensure the required product purity?
For solvent regeneration applications, DeltaMem uses batch processes to provide precise control over final product quality. By adjusting the batch time, the desired residual water content, whether below 1 wt% or as low as 0.1 wt%, can be achieved reliably and reproducibly, enabling the plant to meet different customer specifications with a high degree of consistency.
