Industrial Units / Pervoration units
The technology for your dehydration needs
Our compact pervaporation skids process liquid feeds directly, without energy-intensive evaporation. This delivers a clear efficiency advantage over conventional distillation.
Efficiency, simplified
Our pervaporation process handles your feed directly in the liquid phase, eliminating the need to evaporator the entire stream beforehand. The results is significant energy savings.
A key benefit for your operation is flexibility: Our systems respond dynamically to fluctuations in feed qualities.
Whether the water content shifts or the chemical composition varies, our membranes allow for immediate adjustment of operating parameters. Working closely with you, we develop a tailored configuration that ensures consistently high purity, even when upstream processes are unstable.
Scalable solutions
We offer the right system for every requirement. Our portfolio includes both highly specific custom plants and cost-effective standard solutions:
- Standardised batch plants: We have developed a standardised system for capacities of up to 5,000 litres per day of wet solvent.
- Industrial continuous systems: For larger requirements, we provide units with flow rates ranging from a few litres per hour up to 4,000 litres per hour.
- Straightforward integration: Our skids can be delivered turnkey, including full automation, or prepared for integration into your existing control system. In close collaboration with your team, we develop a solution that integrates seamlessly into your infrastructure and process flow.
Broad chemical compatibility
Our pervaporation units are suitable for a wide range of chemical systems, including
- Alcohols: ethanol, isopropanol (IPA), n-Propanol, sec-Butanol
- Specialty chemicals: acetonitrile, tetrahydrofuran (THF), acetone, acrylonitrile
- Esters and borates: methyl acetate, ethyl acetate, trimethyl borate
- Specialty solvents: cyclopentanone, methyl-THF
Stability that delivers value
Long-term performance is central to economic efficiency. DeltaMem systems are designed for a service life exceeding 20 years. At their core, our membrane modules are exceptionally robust. While the market average is often considerably shorter, our membranes achieve an average lifespan of over four years. In some customer applications, the same membrane sets have been operating for up to twelve years without any loss of performance.
We support you throughout module replacement and ensure, through our quality control, that your plant maintains the maximum performance and selectivity across its entire lifecycle.
Frequently asked questions
Why is pervaporation superior to vapour permeation?
Pervaporation treats liquid streams directly, avoiding the substantial energy required to evaporate the entire feed – a necessity in vapour permeation. This makes the process more efficient and enable a more compact plant design.
Does DeltaMem offer automation solutions?
Yes. We supply turnkey plants including programming and commissioning. Alternatively, we provide detailed functional specifications to ensure seamless integration into your existing control system.
How do DeltaMem pervaporation plants react to fluctuating feed qualities?
Our systems operate with high degree of stability. By continuously monitoring of process data, DeltaMem systems dynamically adjust operating parameters to ensure consistent product quality at all times.
What type of maintenance is required for pervaporation systems?
DeltaMem plants are largely maintenance-free. Our specialists support membrane module installation of membrane modules and perform regular performance checks to maximize membrane service life.
