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.      

It was invented by German BASF, the first generation  Random packing. To compared with Raschig ring, the most important improvement is increase two row of  inward ligule. It promotes liquid-gas liquidity and improve tower’ s packing’ s mass transfer performance.

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.      

it was invented by south china university of technology. Unique conjugated curve finned structure can change point-to-point contacting instead of linear contacting between packing. Therefore, it promote liquid evenly distribution, avoid packing overlapping phenomenon and increase liquid gathering & dispersing etc..

This is an improved pall ring. The main improvement is to increase the turning over and wall thickness at both ends. Without changing the separation efficiency, the bed height can be reduced. So as to reduce the pressure drop..

It was developed by British company MTL Ltd, which also called CMR. Metal Cascade Ring is a new type of bulk packaging with the advantages of high capacity,good stain resistance and low pressure drop.Its sides have one or two beveled edges, which have hhigher mechanical strength and better gas passage than pall rings.Metal cascade rings feature a rectangular opening,curved leaves,tapered edges, and reduced height

It also called Heilex ring, crown-type raschig ring and so on. It is a new type of Perforated Packing. Wavy gas-liquid interface enlarges liquid’ s contacting area and also improve gas-liquid flow efficiency. In addition, interlacing cone type vertical structure can largely reduce towers’ packing nesting, wall flow and unevenly distribution.  

Hiflow Ring is a 3rd generation high performance tower packing which provides an optimal design of high mechanical stability, void fraction and superior mass transfer performance.  

It was invented by Koch-glitsch. Inner arc tabs will increase uninterrupted flows of gas and liquid while providing additional drip points to enhance liquid film surface renewal for improved mass and heat transfe.
