T.C.I Metal Random Packing
T.C.I SPECIAL MATERIAL LIMITED LIABILITY COMPANY has developed the following most commonly used metal random packings:

High Efficiency Metal Random Packing takes the performance advantages of saddle design and ring styles, the combination structure thus gave birth to one of the most successful high efficiency packing. Its unique shape ensures low liquid holdup and low pressure drop. The external geometry prevents the packing from interlocking or entangling, ensuring the randomness and optimum surface area within the packed bed, while the internal fingers, arches and vanes promote optimum interfacial gas/liquid contact with minimal drag or hold-up. Energy consumption is reduced, due to lower reflux ratios.
Metal random packings are available in various materials of construction such as:Carbon Steel              Stainless Steel Titanium and Zirconium     Copper Aluminum
The general applications:

1. l  Various separation, absorption and desorption equipment
2. l  Normal atmospheric pressure reduced and vacuum distillation plant
3. l  De-carbureting and desulfuration systems
4. l  Ethy1 benzene separation
5. l  Iso-octane/toluene systems

Metal Pall Ring (MPR)

Pall ring is one of the most common and well known packing, Metal Pall Ring is an industry standard design media developed from the raschig ring and is used widely in all variety of applications.  By minimizing the number of contours and crevices that can cause liquid hold-up and potential entrainment, the Metal pall ring geometry enables high gas and liquid transfer rates. The opened cylinder walls and inward bent protrusions of the Metal pall Ring allow greater capacity and lower pressure drop than standard cylindrical rings. This open ring design also maintains an even distribution and resists wall-channeling tendencies. The interior and exterior contacting surfaces of the metal pall ring provide for an effective distribution of liquids and gasses and resist plugging, fouling and nesting. Pall rings are available in a wide range of materials.

1. l  Lower pressure drop
2. l  Good liquid / gas distribution and higher mass transfer efficiency
3. l  Versatility, Easily wettable, High resistance to fouling, High Temperature
4. l  High Mechanical Strength, suitable for deeper beds
5. l  High temperature resistance

Metal Intalox Saddle(MIS)

T.C.I Metal Intalox Saddle (equivalent to IMTP) is high performance random packing, successfully used in mass transfer towers both small and large diameter. It is frequently used in deep vacuum towers where low pressure drop is crucial and also high pressure towers where capacity significantly exceeds conventional trays, offer a 30% lower pressure drop than Pall Rings but with a lower liquid hold-up. Metal Intalox Saddles’ physical shape permits maximum randomness and minimum alignment, Advanced design gives it (MIS) a high rate of liquid film surface renewal producing a high mass transfer rate, leading to a greater capacity and efficiency compared to other random packings, Large number of contact points for homogenous distribution of liquid and gas, Facilitates shorter packed bed heights.

Metal Intalox Saddle (MIS) is high performance random packing, successfully used in

1. l  Transfer towers both small and large diameter
2. l  Deep vacuum towers where low pressure drop is crucial and also high pressure towers where c capacity significantly exceeds conventional trays
3. l  Distillation, absorption etc
4. l  High pressure towers

Metal Raschig Ring (MRR)

Metal Raschig Ring is proven in a wide range of mass transfer applications. A full range, of MRR sizes and materials are available to tackle a wide range of separation applications. MRR have a long history of improving separation efficiency. The simple big opening structure provides one of the largest surface areas among tower packing options. The advantages of metal raschig ring packing are high capacity, low pressure drop, high separation, cold and heat resistan, t, long life.

T.C.I Metal Rachig Ring (MRR) is used in

1. l  Petrochemical distillation and extraction applications
2. l  Absorption in gas processing and combustion plants
3. l  Desorption in water treatment

Metal Cascade Mini Ring (MCMR)

T.C.I Metal Cascade Mini Ring, MCMR for short, and a lower aspect ratio increases capacity and reduces pressure drop and the highly exposed internal and external surfaces give a high efficiency vehicle for liquid – gas contact with good mechanical strength. Lower aspect ratio (H/D 1/3) increase capacity and reduces pressure drop: MCMR’s preferential orientation in a packed bed with the cylindrical axis in the vertical plane, allows a free passage for gas to flow through it. Smaller column size without sacrificing the efficiency: The lower pressure drop and higher throughput of MCMR enables a smaller column diameter and fan size to be specified in new installations, the highly exposed internal and external surfaces provide an efficient vehicle for liquid–gas contact, by multiple drip-points. More resistant to fouling: Because a combination of Metal Cascade Mini Rings' vertical alignment and open sides, allow any solids present to be flushed downwards through the packed bed. Good Mechanical Strength, which allows Metal Cascade Mini Rings' use in deep packed beds that have a higher hydraulic capacity.

1. l  Desulphurization and decarburization system in compound ammonia plant

l  Decompressed plant in crude oil separated plant

1. l  All kind of separation process such as separation of methanol
2. l  Separation of organic acid, absorb towers etc.
