NANO FILTERATION

The proposed membrane hybrid techniques are OSN and pervaporation (PV) enabling separation of solvent based mixtures at the closer molecular level by applying a pressure gradient across or a vacuum at the permeate side of a selective membrane, respectively. Such chemical process intensification in the solvent recovery and purification business is expected to lead to significant reductions in production costs, materials usage, energy consumption, waste production, as well as risks and hazards. This could offer a suitable alternative for classical distillation based solvent purification.

  • To develop a novel Organic Solvent Stable Tight UF and NF membranes
  • Optimization of developed membranes for improved flux and separation efficiency
  • Optimized membranes will be explored for pilot studies in pharmaceutical and solvent recovery applications

Advantages

  • OSN membrane technology is applicable for non-polar through polar to polar aprotic.
  • Reduces process costs and increase its efficiency.
  • Environment-friendly approach of OSF selective membrane technology hybrid with PV process proposes an apt and economically viable, waste minimization, more solute/solvent recovery option for existing process such as energy intensive distillation, extraction or solvent separation.
  • Molecular weight cut off region ranges between 200 and 1000 Dalton.
  • OSF with PV system design is easy to maintain, low maintenance, membrane backwash is possible and good mechanical strength of the membrane.

Key Feature &Major Impact

  • High Chemical resistant membranes; membranes can be operated at high temperatures
  • Membrane filtration expansion to Non-aqueous applications
  • Industries from oil refining to pharmaceuticals could reap major benefits from reduced energy consumption and simplification of solvent based processes just as the desalination industry has benefited from the introduction of reverse osmosis membranes

 

OSN MEMBRANES

Organic solvents are widely used in industries such as pharmaceutical, chemical, petrochemical, and food and beverages. However, most of the solvent manufacturer and recycling companies have been utilizing and rely on the energy intensive and current distillation process. We developed proprietary technology and unique hollow fiber membrane material to separate the organic solvents with moderate CAPEX and OPEX in comparing to the conventional approaches.

Applications

Application fields for nanofiltration are being extended to the full spectrum of chemical process industries, e.g. pharma, fine chemicals and flavour & fragrance with the development of solvent-stable membranes,

  • Solvent recovery
  • Solvent exchange
  • Recycling of organic solvents Purification

Note:
1. Let us know the solvent used, we give a better solution
2. You have to provide a shed for 2000 sq.ft at your cost.
3. 90% of the solvent will be recycled and you have to pay for the recycling process.
4. We will provide the required machinery at our cost
5. Our’s is a Singapore collaboration unit.
