Rashing – Raschig rings are cylindrical packing elements made from durable materials such as polypropylene (PP) and stainless steel (304L – 316L). These rings are used in processes like absorption, distillation, scrubbers, and flue gas treatment in industries such as fertilizers, chemicals, and petrochemicals to increase the liquid-gas contact surface. They serve functions such as washing gas with water, cleaning toxic wastes, and odor removal, thereby enhancing the efficiency and environmental compliance of the processes.
