Product Description

Saiptech Grid Structured Paking

Structured Grid Packings are specifically designed to provide reliable operation in severe services that are susceptible to fouling, erosion, coking and high solids content. At Saiptech, there are three distinct styles of structured grid packing: styles 2, 3 & 25A.


Style 2 is optimized for maximum capacity, low liquid holdup and minimum pressure drop and provides the greatest fouling resistance.
Style 3 provides improves efficiency because it has a larger projected area perpendicular to the gas flow (causing higher localized vapor velocities).
25A structured packing was one of the first grid packings ever applied and is still widely used in refineries around the world.

Typical Parameters
 

Structured Grid Packing		STYLE 2	STYLE 3	STYLE 25A
Specific Surface Area	m^2/m^3	45	45	37
Packing Weight	kg/m^3	263	263	242
layer Height	mm	70	70	54

Note: Relative mass transfer efficiencies are highly dependent on packing geometry (blade design and angles) and cannot be accurately predicted using relative differences in the specific surface areas. Pack weight is dependent on packing thickness and material type.



Application

Structured Grid packing is developed primarily for severe services which are susceptible to fouling, erosion, coking and high solids content. Our packing is installed in rigid modules stacked in successive layers with a fixed orientation, which minimizes the overall pressure drop while simultaneously increasing tower capacity and/or efficiency.
The blades of the grid packing induce turbulent contact between the rising vapor and descending liquid. There are two distinct styles of structured packing. Style 2 is optimized for maximum capacity, limited liquid holdup and minimum pressure drop. Style 3 is optimized for improved efficiency without limiting either capacity or fouling resistance.
