MTL Style 2
High Capacity



MTL Style 3

High Efficiency

Features:
MTL Structured packing is particularly useful in many refinery services where random or other structured packing will coke or foul, potentially causing premature shutdowns. The all-welded construction provides a strong assembly that can withstand the rigorous conditions often found in both refinery and petrochemical services.
MTL structured packing is constructed in modules. The vertical blades of the packing are fixed in position with welded cross members. During installation of either style, each successive layer of the grid packing is rotated 45 degrees to the previous layer. This specific orientation eliminates horizontal planes where liquid and/or solids can collect. The Style 3 packing has a greater projected area perpendicular to the gas flow causing higher localized vapor velocities, effectively providing higher efficiencies.

Application:
MTL structured 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.

 

Material available:
MTL can fabricate grid packing from many materials to meet your demands.
Carbon Steel, Stainless Steel (410s, 304ss, 316Lss, and 317Lss), and many High Alloy and Duplex Specialty metals.



MTL Style 25A

Features:
MTL Style 25A is a good choice for applications that have fouling, erosion, coking and process upset tendencies. Style 25A is extremely structurally durable and has a high void space percent suiting it well for turbulent vapor streams in the 1000° F (538°C) range. The structured grid packing surface design reduces coking and fouling due to stagnant overheated droplets by providing rapid drainage. For the most part, the rapid drainage makes it self-cleaning. The grids install in successive layers. They can be removed and cleaned, or replaced, easily when necessary. Structured Grid Packing can be made to industry standard design and is available in a wide range of steel and alloy materials to handle high fouling services.

Application:
• Scrubbers with High Solids
• Coker Fractionators
• Atmospheric Crude Units
• Vacuum Crude Units
• Resid Cracker
• Reactor Off-Gas Scrubbers
• Cracked Gas Quench Towers
• Edible Oil Deodorizers

*Relative mass transfer efficiencies are highly dependent on packing geometry (blade design and angles) and can not be accurately predicted using relative differences in the specific surface areas.

**Pack weight is dependent on packing thickness and material type.
