All About Structured packing, Random Packing, and Mass Transfer Trays

StructuredPacking

First let’s start with structural packing which is commonly in demand across different industrial sectors. Structured packing is highly popular because of its versatile range of applications. They are considerably more expensive than random packings. The range of materials used for structured packing is specially designed for use in distillation and absorption columns.

Structured packings come in a variety of materials, which includes metal, plastic, or wire gauze. The thin corrugated metal plates result in inclined flow channels with a high surface area.

Some of its essential features include high separation efficiency, low-pressure drop, good wettability, boosts useful capacity, etc. You can find many structured packing suppliers who deal with many other types of structured packing.

Random Packing

Random packing is mainly used for absorption, stripping, fractionation operation in gas and chemical plants. They provide an increased surface area, which results in a more efficient process. Unlike the structured packings, their arrangement is not in columns with any specific method or orientation. Some of its important features include cost-effective, high mechanical strength, and they are available in different sizes, which gives a different combination of efficiency and pressure drop.

Mass Transfer Trays

They play an essential role in thermal fractionation. Mass transfer trays are used for distillation processes in chemical plants. Following are some of the trays available for mass transfer.

1. Sieve trays- Sieve trays are punched holes for passage of the gas. With limited load range, sieve trays are the simplest and hence the cheapest types of mass transfer trays available.

2. Valve trays- In the valve trays, liftable caps are used to cover the perforations. They use a dynamically variable valve opening, which eases the gas flow rate.

3. Bubble cap trays- These are another variety of trays that are made with inverted bubble caps having vertical slots fixed over cylindrical risers. They are also suitable for low liquid loads.

4. Dual Flow Trays- This tray operates with liquid continuously seeping through the holes. It's like a sieve tray with no down corners, which give more tray area and higher capacity than any other type.

Packing vs. Trays

Trays are suitable in application with liquid rates of 30 m3/m2 and above. Structured packings are typically used in lower liquid rate applications. Trays and packed columns both have several advantages and disadvantages according to its area of operation. One of the benefits of packed towers is that it provides continuous contact without full disengagement of the vapor and liquid.

With this, ease of installation, mechanical simplicity is its other significant advantages that you can take into account while making a purchase. When it comes to trays, with its benefits, they do have some operating limits which depend upon the area of its uses.

Last but not the least, before choosing the right product, it is essential to consider a variety of issues to make the best choice regarding the type and design you want for your own requirement. The above-mentioned information would help you to make more informed decisions.

Advanced technology based industrial products

The most widely recognized application territory of the column internal is the petrochemical business. These are broadly utilized for the partial refining process. In this, the volatile fluids or gases are isolated.

It is a fact which is upheld by the vast majority of the research works that the effectiveness of a mass transfer column is broadly impacted by the even circulation of fluid over the segment cross-area. Amid the flow of the fluid, when the jet of fluid hits a bed, at contact focuses, the jet spreads streams down. Amid the assembling of the fluid distributors, it ought to be remembered that the feed guides cover adequately all together toward anticipating undesirable zones. This is being done to accomplish the homogeneous water systems density.

So as to achieve high mass transfer proficiency, it is compulsory to plan the fluid distributors as indicated by the enumerations. The Structured Packing Suppliers are selling up the range so as to accomplish the largest amount of effectiveness. These are utilized that the focuses where immiscible fluids are isolated. These are given the minor spaces. As per the rule, when two miscible fluids have gone through this at high pressure, they get isolated.

Another guideline related with the working of this is when profoundly volatile fluids are interacted with one another, at the point having a vast surface area, at that point, instead of blending, they get isolated. Along these lines, fractional distillation happens.


Structured manufacturing suppliers are endeavouring hard to give extraordinary quality items to the market. As these are utilized in the earth of high weight and temperature, it is obligatory to build up this utilizing premium evaluation material. The stainless-steel alloy is a hot choice of material which is broadly utilized for this reason.

Use of Liquid-Liquid Coalescers in Oil and Gas Industry

The liquid-liquid coalescers are designed specifically to remove the emulsified water of hydrocarbons. These are available in many options for medium and in packs for liquid passage. The fluid is passed through this coalescer through the medium as tiny suspended droplets which are further converted to larger droplets. Larger droplets respond better to gravity and works better in oil and gas industry. According to the different types of packs each column internals make, the conversion and absorption of fluid droplets change. Here are some of the types of packing for liquid-liquid coalescers.

1. Plate packs

The separation of oil and water is done with droplets settling. The plate pack coalescer is used in the liquid session so as to optimize the degree of liquid-liquid separation. They are highly used for appliances where fouling is required. The medium often used in these plates include depth polyesters.

2. Matrix packs

These are quite strong and sturdy being made out of corrugated sheets. The liquid is directly passed through the surface allowing coalescers to take place. The larger droplets flow separately after the separation. Made usually out of nylon or glass, these are designed for a high performance.

3. Dual media mesh

The liquid-liquid coalescer is manufactured with metal or plastic filaments to combine as layers. The liquid droplets are allowed to coalescence directly from the surface. These types of plates are used usually when it comes to cleaning and polishing appliances. Their ability to highly perform and polish makes them best to use for such needs.

These plates are usually packed with structured packing in order to export for various needs. With a well structured packing supplier, you can not only get the packaging but get to the dealers of these plates.

What is the difference between Structured Packing & Random Packing?

The term structured packing alludes to the scope of uncommonly planned materials for use in assimilation and refining sections. Organized packings normally comprise of thin creased metal plates or bandages/networks arranged in a way such that they compel liquids to take confounded ways through the segment, along these lines making a substantial surface zone for contact between various stages.

Structured Packing is obtained from creased sheets of punctured emblazoned metal or wire dressing/work. The outcome is an extremely open honeycomb structure with slanted stream channels giving a generally high surface zone however with low protection from a gas stream.

Random Packing

Random packings, as the name suggested, are dumped into a section amid establishment and permitted to fall in irregular. Little packings emptied arbitrarily into a vessel is surely the more prominent and ordinarily utilized type of pressed pinnacle structure.

Structured Packing v/s Random Packing

Structured packings are impressively more costly per unit volume than random packings. They come in various sizes and are flawlessly stacked in the segment. Structured packing typically offers less weight drop and have higher productivity and limit than random packings.
