Raschig rings RING-R
Raschig Rings:
Raschig ring (RING -R) is used for filling work volume of packed columns and devices. It is aimed at increasing intensity of heat exchange and mass-transfer processes in chemical, petrochemical, oil-refining equipment, etc. R-Ring is also to be used in sewage and water supply systems, in ammonia and mineral fertilizers production
Raschig rings refer to random packing. Their surface is 30% larger than that of cylinders and
balls.
R-Rings can be made of carbon steel, stainless steel, polypropylene, PVC, PVDF, ceramics, etc.
Acid-resistant ceramic packing material is used for filling packed columns of other mass transfer equipment which works at the temperature not higher than 120 Celsius degree in acid environment.
Application Range:
- ethylene extraction columns;
- mass-tranfer columns separation devices;
- carbon dioxide and hydrogen sulphide absorbers and flash tower;
- liquid extractors;
- carbon monoxide converters;
- dimethyl terephthalate running column;
- NH3 extraction devices;
- petrochemical and medical equipment.
