Graphite Internals For Mass Transfer

Graphite internals are the ideal complement of graphite and PTFE lined columns. On the basis of a long process competences and experience, our engineers are able to perform accurate selection of the suitable internals for each process unit, from distillation column to falling film absorber.

Graphec® column internals show significant advantages, when compared to plastic internals (PTFE) or metallic internals:

• Superior thermal stability in a large temperature range (Graphec® is not thermoplastic material and it does not deform during its lifetime);
• Complicated geometry with cemented joints;
• High wetability due to low surface tension and higher roughness of graphite;
• Lower price compared with PTFE or metallic internals.

Graphec® internals product line includes:

• Distributor plates: massive graphite plates with crowns or graphite sieved pipes for proper distribution of liquid or gas along the packing section;
• Tunnel cap, sieved and bubble cap trays with downcomers and weirs, eventually assembled in a complete frame, with tie rods and gaskets;
• Dip pipe, chimney plates, support grids, re-distributors and support plates;
• Packing: graphite Raschig rings.
