PP hump support

Plastic hump supports (also called packing support grids or bed limiters) are essential components in packed columns and distillation towers, designed to distribute weight evenly and prevent packing material (such as Pall rings, Raschig rings, or structured packing) from collapsing or blocking the column's lower sections. Key Features of Plastic Hump Supports Material: Made from PP (Polypropylene), PVDF (Polyvinylidene Fluoride), or CPVC, selected for chemical resistance. Design: A wave-like (hump) or grid-pattern structure that allows high open area (60-90%) for optimal fluid flow. Function: Supports the weight of packing media to prevent breakage. Ensures uniform gas and liquid distribution. Prevents packing from falling into the lower part of the column. Corrosion Resistance: Suitable for acidic, alkaline, and organic chemical environments. Lightweight & Easy to Install: Far more durable than metal supports in corrosive conditions. Applications 1. Chemical & Petrochemical Industry Distillation, absorption, and scrubbing columns for: Sulfuric acid, nitric acid, and hydrochloric acid processes. Gas treatment (H₂S, CO₂ removal). Solvent recovery in pharmaceutical & agrochemical industries. 2. Water & Wastewater Treatment Scrubber towers for removing ammonia, chlorine, and VOCs. Cooling tower packing support to maximize heat transfer efficiency. 3. Air Pollution Control Used in flue gas desulfurization (FGD) systems to hold random packing. Odor control scrubbers for industrial emissions. 4. Oil & Gas Industry Glycol dehydration towers (natural gas processing). Amine sweetening units (removing H₂S & CO₂).
