Tower Internals

The support grid plate has to be constructed in a way that it allows flow of gases and liquids in the column as unrestricted as possible. This is especially important in the area between support grid and packed bed there is the danger of blocking the gas flow by an unsuitable packing support. The main function of these devices is to support the tower packing bed structurally. Support grids work in both structured and random packing processes for a wide range of purposes.  

A complete range of mist elimination devices including mesh pad demisters ,vane type mist eliminators and liquid coalescers for separation of entrained liquids are offiered. Products are available in a variety of metals, plastics and thermoplastics for a wide range of applications.Mist eliminators are employed at the top of a packed column or in conjunction with a collecting tray between two packed beds. They separate liquid droplets from the gas stream. Droplet discharge from the column and/or the liquid entrainment from one stage to the next is minimized. Our mist eliminators are engineered for optimal performance under specific applications.  

Bubble cap trays are used primarily in applications with very low liquid loading and very high flexibility, where large turndown ratios are required.  A bubble cap has riser or chimney fitted over each hole, and a cap that covers the riser. The cap is mounted so that there is a space between riser and cap to allow the passage of vapor. Vapor rises through the chimney and is directed downward by the cap, finally discharging through slots in the cap, and finally bubbling through the liquid on the tray.      

Bubble cap tray is a flat perforated plate with risers (like pipes) around the perforations, and caps in the form of inverted cups over the risers.The caps are usually equipped with slots or holes through which vapor comes out. The cap is mounted so that there is a space between riser and cap to allow the passage of vapor. Vapor rises through the riser and is directed downward by the cap passing through slots in the cap, and finally bubbling through the liquid on the tray. As vapor has to pass through many passages this lead to higher pressure drop and lower capacity than other conventional trays. Liquid and froth are filled on the tray to a depth at least equal to the weir height or riser height, giving the bubble-cap tray a unique ability to be used for reaction applications.      

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).
