Columns for distillation & rectification

Material: Borosilicate glass 3.3, stainless steel, Hastelloy C22, ceramic, PFA, PTFE, glass-lined steel
Size: DN 70 to DN 600.
Larger diameter columns are available on request.

Rectification and distillation columns are used for thermal preparation processes. These columns are typically packed with random packings such as raschig rings, ceramic saddles or PFA packing elements, or structured packings made by various manufacturers, including Sulzer Chemtech and Koch-Glitsch. Depending on the required separation performance and process media, random packings or structured packings are selected.

The columns are made from Borosilicate glass 3.3 and are available in sizes from DN 70 up to DN 600. Larger diameter columns are also available and are made from glass-lined steel.

In addition to the columns themselves, heat exchangers for condensation of the vapors are needed. Two different types of heat exchangers are typically used: spiral condenser (glass) and shell and tube heat exchangers. Shell and tube type heat exchangers are built with inner tubes made of borosilicate glass, glass-lined steel, silicon carbide (SiC), tantalum or other metals, depending on process parameters and other requirements.
