#structured packing

Structured packing is a range of specially designed materials for use in absorption and distillation columns. Structured packings typically consist of thin corrugated metal plates or gauzes arranged in a way that forces fluids to take complicated paths through the column, thereby creating a large surface area for contact between different phases.

Structured packing is formed from corrugated sheets of perforated embossed metal, plastic, or wire gauze. The result is a very open honeycomb structure with inclined corrugations or flow channels, giving a relatively high surface area but with very low resistance to gas flow. The surface enhancements are chosen to maximize liquid spreading. These characteristics tend to show significant performance benefits in low-pressure and low-irrigation-rate applications. Steeper or larger corrugation angles lower the pressure drop at the cost of lower separation efficiencies. The sheets are packaged into elements that are piled up in alternating layers, forming a packed bed that fills the complete cross-sectional area of the fractionation tower. To fully utilize the separation efficiency, structured packings require a careful distribution of the liquid on top of the bed. For the packings to reach their highest efficiency the variation in the liquid distribution should be less than 1–2%. In high purity applications with many equilibrium stages, the packing needs to be installed in multiple packed beds, between which the liquid is collected and re-distributed anew.

Fractionating columns are crucial in industries like chemicals and pharmaceuticals, where they play a central role in separating mixtures based on boiling points. These columns are essential in distillation processes, where liquid and vapor phases interact repeatedly to achieve optimal separation.

One of the key factors in maintaining high separation efficiency within fractionating columns is the effective management of liquid and vapor traffic. Liquid distributors, which evenly distribute the liquid across the column’s packing or trays, are essential in ensuring proper flow dynamics. Without proper flow management, maldistribution can occur, reducing the contact between liquid and vapor phases and ultimately compromising column efficiency.

At S-Cube, we utilize state-of-the-art simulation tools to analyze the behavior of liquid and vapor traffic within fractionating columns. These advanced simulations provide insights into how varying flow rates and operational conditions impact column performance. This data allows us to design column internals such as distributors, packing, and trays — that precisely match the necessary liquid flow rates, while also accommodating a wide range of operational scenarios.

This meticulous design process is at the heart of ensuring that the column operates at peak efficiency. By optimizing the flow and minimizing energy consumption, we help our clients achieve the highest level of separation performance. Our focus on precision and efficiency supports our clients in reaching their specific industrial goals, ensuring their processes are both energy-efficient and reliable.

At S-Cube, we understand that every operation is unique. That’s why we tailor our solutions to each client’s specific needs, delivering effective, reliable, and sustainable processes for industries across the board. Our approach is focused not just on performance, but on improving energy efficiency and reducing operational costs, providing our clients with the best of both worlds.

Demister Pads (Mist Eliminators) are key components used to prevent product loss, enhance filtration efficiency, and protect equipment. Typically mounted at the top of vessels, they trap liquid droplets carried by gas before releasing the clean gas. These pads are used across industries such as cooling towers, ventilation systems, and air scrubbers.

How Demister Pads Work

Gas streams pass through the demister pad, where small liquid droplets coalesce into larger ones. These heavier droplets are trapped and drained back into the system, ensuring only gas flows out. This prevents toxic chemicals and hazardous liquids from being released, thus protecting equipment from corrosion and electrical damage.

Working Principle

In processes where gas and liquid interact, entrainment of liquid droplets occurs. Demister pads separate these by causing smaller droplets to merge into larger ones that settle back into the liquid. The pad’s mesh-like structure forces vapor through obstructions, allowing liquid droplets to collect while gas exits.

Key Benefits

Efficient Mist Removal: Properly installed demister pads can capture nearly 100% of liquid droplets from contaminated vapors, reducing emissions and solvent losses.

Equipment Protection: Prevents liquid droplets from escaping, reducing the risk of equipment damage due to corrosion or fouling.

Custom Design & Easy Installation: Demister pads are custom-built to match facility needs and are easy to install. They are designed for low pressure drop and corrosion resistance, ensuring long-lasting performance.

Versatile Design: Available in various shapes and sizes to fit specific systems, these pads can be tailored for vertical or horizontal flow processes.

Materials & Applications

Made from stainless steel, polypropylene, or PTFE, demister pads are durable and suitable for high-temperature and corrosive environments. These materials are ideal for industries like petrochemicals, pharmaceuticals, and refineries.

Industries Served

Refineries: Remove oil mist to protect equipment.

Chemical Plants: Separate acid or alkaline mists from vapors.

Cooling Towers: Reduce water loss and improve efficiency.

Column internals are only devices which dominates in the distillation process. They are nothing but the catalysts of mass transfer operation.

Most used column internals are packing and trays (Plates). Various industrial sectors like energy, petrochemicals, biofuel, water treatment, refining, gas processing etc. has exposed to importance of these column internals. Types of internals has been described below,

Packing

Packing are divided in further 2 types,

1. Structured Packing –

Structured packing is type of internals in which materials are arranged in unique way to enhance the efficiency of the mass transfer operation. Corrugated sheets or wire mesh materials are being used in structured packing which allows to fluid and vapour streams to get interacted with each other for better output. Structured packing has textured design which helps to increase the spreading of the liquid.

Various types of structured packing like gauge/wire mesh, knitted type, sheet metal type and grid type of packing. Each of the type has separate specifications and contribution to the process.

Without vapor liquid contact it’s impossible to have mass transfer of fluids. Better mass transfer will be followed if we use the packing which can create thin filmed liquid distribution which enhances the performance. Some packing types has textured designing on plates which increase spreading of the liquid. Such packing is more effective in case of low pressure applications.

It’ll be the best choice if the process requires the high flow rate and lower pressure drop. Lower pressure drop leads to higher volatility which turn to be an advantage in operation. Structured packing also helps to reduce foaming and increase energy efficiency. Higher capacity of packing tends to increased operating rates.

2. Random Packing-

These are the type of internals which directly get dumped into the column to carry out the process. Required surface area for operation is being provided by whole random packing. It’s used in various operations like distillation, stripping, scrubbing and Liquid-liquid extraction Etc.

Random packing is used to allow contact between 2 fluids such as liquid with gas or with liquid-liquid contact. Random packing offers higher pressure drop comparatively to structured packing. The packing selected should offer large surface area to achieve optimum surface area and effective mass transfer.

Various types of random packing which is being used in process like Raschig Ring, Pall Ring, IMTP Saddle Ring etc. which will be preferred as per the process recommendation. These packing are used in cases of small diameters towers, processes with low pressure drop, corrosive applications and in case of increased capacity as well.
