Structured packing is developed for extraction process, absorption process, and distillation of polar systems, particularly suitable for chemical absorption process of low liquid loading case.

1. Lower pressure drop than conventional structured packing;

2. Good anti-coking/blocking performance.

Types of structured packing

1. CORRUGATED SHEET METAL PACKING
2. NEW CORRUGATED SHEET PACKING
3. EXTRACTION STUCTURED PACKING
4. GAUZE TYPE STUCTURED PACKING
5. GRID SERIES GRID PACKING
6. Hold down grid

Mainly used for the application where coking is likely to occur. Typical applications are as follows:

● Atmospheric or vacuum tower: wash section.

● FCC main fractionator: slurry pump around section.

● Coker or visbreaker fractionator: wash section.

Hold-down grids, or bed limiters, are situated directly over a packed bed to prevent the movement or discharge of the packing.

• Random packing
• Hold down grid
• Packing support grid

Random Packing

TIS Random packing combines the advantages of ring packing and saddle packing, could be used inthe field of rectification, absorption and extraction process. Packing Material can be metal, plastics or ceramics.

1. Refrain from wall-flow effect and amplification effect, which could be applied in large industrial column

2.Higher proportional open space divided by inner tri-dimensional wing makes liquid distribution easier with more surface area and more dripping points;

3. Capacity of random packing is increased by 25% compared with conventional random packing.

4.Capacity of random packing is increased by 35% compared with conventional random packing.

Hold down grid

Hold-down grids, or bed limiters, are situated directly over a packed bed to prevent the movement or discharge of the packing.

A Hold Down Grid for Random Packing (Attached to the Column)

It is a grid-type bed limiter fixed to the column wall.

B Hold Down Grid for Random Packing Assembled with Liquid Distributor

It is a grid-type bed limiter assembled with a liquid distributor.

C Hold Down Grid for Random Packing for A Small Column

It is a grid-type bed limiter assembled with a liquid distributor or attached to the column.

Packing Support grid

The main function of the packing support grid is to support the tower packing bed. Random packing need support grids with flat bars that clamp to the support ring. The large open area ensures high efficient gas and liquid flooding.

Features:

• Big open area
• High strength
• Large free sections
• Simple design

B. Corrugated Plate Type Packing Support

It is a hump-type support that allows gas and liquid to pass through its inclined corrugated plate. It has a large open area for gas and liquid to pass through and it does not significantly add any pressure drop.

C. Subway Grating Type Support

It is a grid-type support that has a mesh cover to prevent leakage from random packing.

D. Grid type packing support

It is a slotted deck support that has a mesh cover to prevent leakage from random packing. it is used in small columns.
