Organic Solvent Filtration

In the fine chemical industry, organic solvents are widely used. Filtration plays a key role at every stage of your synthesis: Filtration of raw materials, chemical inter-reactor filtration, catalyst filtration and safety filtration. Solvents are usually hazardous and designing a filtration system for filtering solvents requires careful consideration.  In choosing the most suitable filter cartridge for your process, several elements such as temperature and chemical compatibilities must be taken into account on top of the traditional elements (flow rate, viscosity, solid quantity).

In organic chemicals, temperature and chemical compatibilities are indeed key aspects:

• The chemical compatibility is crucial to prevent the release of some plastic particles in your products.  The solvent or mix of solvents and the active molecules can influence the reactive environment’ s chemical compatibility with the cartridge used.
• The temperature of the reactive environment can also influence the cartridge choice.

Filter elements for the solvent filtration

For the solvent filtration, we recommend using our GPFA-Series membrane cartridges along with our sanitary vessels. Our membrane cartridges with absolute efficiencies down to 0.05 micron and with high chemical compatibility are the best solutions to fulfill your requirements. Our GPFA-Series are adapted up to 185°C and are compatible with a wide range of highly reactive chemicals including:

• Acetic Acid (10%)

• Hydrofluoric Acid (50%)

• Hydrogen Peroxide (30%)

• Nitric Acid (conc.)

• Phosphoric Acid (conc.)

• Sulfuric Acid (cavonc.)

• Ammonium Hydroxide (conc.)

• Potassium Hydroxide (conc.)

• Sodium Hydroxide (conc.)

• TMAH (5%)

• Aqua Regia (HNO3:HCl)

• Mixed Acid Etch

Moreover, we offer a large range of cartridge media (polypropylene, nylon, glass fiber, cotton, PTFE, fluoropolymer, PES …) for broad chemical compatibilities. All our products have the certificates required by the fine chemical industry.
