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.
