PERVAP™ and Ceramic Membranes

Sulzer Chemtech has a wide range of superior, proprietary PERVAP™ polymeric membranes. A co-operation with Mitsui Engineering and Shipbuilding Ltd., Japan, alternatively enables us to offer world class inorganic pervaporation membranes. Hereby, selection of the best suitable membrane for a most reliable and economic treatment of each product is possible on a case by case basis.

Key application areas are:

  • Solvent production and recycling
  • Dehydration of alcohols
  • Production of Active Pharmaceutical Ingredients (API’s)
  • Production of fine chemicals
  • Production of flavours and fragrances
  • Production of food and beverage

Membrane Filtration

Sulzer Chemtech’s membrane filtration systems are specifically suitable for the treatment of organic solvents and acids as well as for other advanced applications. Reverse Osmosis (RO), Nano filtration (NF), Ultrafiltration (UF), Microfiltration (MF) for aqueous systems, and Organic Solvent Nano filtration (OSN) systems can be supplied as a stand-alone unit operation, or in hybrid combinations with other technologies. Hybrid solutions offer lower energy consumption, a smaller footprint, lower investment costs and lower heat effects on the product. Typical applications for our pressure driven membrane filtration systems include concentration or purification of API’s catalyst recovery, clarification or concentration of organic and mineral acids, monomer / polymer separation decolourization of solvents, recovery of spent solvents and solvent exchange.
