A Detailed Guide on Coalescer Filter Separator

coalescer filter separator is a mechanical equipment used in the oil and gas processing industries and petrochemical industries to perform coalescence. Combination or coalescence is a way of causing an agglomeration (meeting up) of fluid vaporizers to form bigger droplets that are sufficiently depleted away gravitationally.

coalescer filter separator works in reverse to an emulsifier which makes emulsions. 

A coalescer might be used all alone or as a segment of a bigger separation unit. Choosing the correct type of separating equipment depends on the nature of the substance to be separated.

For instance, an oil coalescer or fuel coalescer is generally used to recuperate oil or fuel from a water-oil mix individually. In contrast, a gas coalescer usually is used to separate gases from gas-fuel or gas-water emulsions.

The Function of a Coalescing Filter Separator

The primary function of a Coalescing Filter Separator is removing or eliminating toxic particles and impurities from different substances. The process fluid can be a gas or a liquid, which are effectively treated under this technological process to make it a valuable form of significance. 

Both components have separate Coalescing Filter Separators; a Gas Filter Separator for gas, and a liquid filter separator for liquids. 

The process removes all the impurities from these components like oil, dust particles, and rock making the substance market-ready.

Working process of Coalescer Filter Separator

Working process of Coalescer Filter separator

Coalescing is a method widely used in filter media to separate fluid mist concentrates and droplets from the gas. Coalescing filter separators are explicitly invented to eliminate submicron oil, water, and other fluid impurities from airflows. It is used to expel mist, hazy toxins, irritants, and scents in petroleum gas vehicle filtration, compressed air filtration, compressed flammable gas filtration, and air oil separation. 

The fluid droplets present in the airflow are eliminated through the coalescence process. At least two liquid droplets come into contact with one another to overcome surface strains of the drops to coalesce. 

Thus, Coalescer filter separator elements can be introduced in a house with three layers of filter layers with polluted airflow going through the filter process inside to outside. 

The inner layer of the element is called a capture layer, and the outer layer is called the coarser drainage layer. A high-productivity coalescing layer is usually placed in between or in the middle of these two layers. When oil mist is to be removed, the fine fiber of the inner layer is generally water absorbent and is adjusted according to the functional saps to be oleophobic and help discharge oil particles. 

Oleophilic borosilicate glass microfibers are fibers used to aid the coalescing layers capture the fine fluid mist concentrates and droplets, which run together along the threads to shape large drops inside the depth of the element.

These large drops are then forced to the outer of the filter channel to eliminate the housing bowl by gravity. Coalescing filter separator will accordingly eliminate particulates at similar proficiency as a particular type of component of an equivalent grade.

Oleophilic borosilicate glass microfibers are used in constructing the coalescing layers to catch the fine fluid products and droplets, which run together along the strands of fiber to form big drops inside the element.

Major Components of a Coalescer Filter Separator

The Coalescer Filter Separator comprises a progression of astound dividers, also called baffle walls or filters, situated at different places of the system. The system is planned to such an extent that the separation equipment traps the various segments of the mixture at regular intervals. 

Similarly, in water-oil separation, baffle filaments separate the denser oil particles and permit water atoms to diffuse and mix at an assortment point under the baffle wall where they can be drained precisely.

Coalescing Filter Separator eliminates contaminants and toxic substances by using three unique instruments: 

  • Diffusion typically applies to particles sized 0.1 microns and smaller. These are dependent upon arbitrary Brownian movement, and they collide into and are caught by the filter. Solids adhere to the filter films, and liquids get together with different droplets to shape more enormous masses. 
  • Interception influences particles about 0.1 to 1 micron in size. A turbulent stream flows particles against the fibers, and they are caught in the filter system. More modest pore size expands capture efficiency. 
  • The direct effect applies to particles 1 micron and bigger. Here, pollutants crash into and are trapped by the fibers. 

In a general Coalescer filter separator, air enters the housing and flows through the media from within to outside the filter element. Combined oil and water droplets gather on the filter fibers and relocate downward because of gravity as they fill in size. The liquids gather in a bowl at the housing base and are consequently depleted away, while clean air leaves the housing through the power source port.

What are the Features of a Good Coalescer Filter Separator?

A suitable Coalescer Filter Separator eliminates all the impurities from your required substances and makes them ready to be used for future production. It has other benefits, too, apart from the efficiency, low cost, and a wide range of pH availability.

Let’s explore some of the features of a good Coalescer Filter Separator.

● It should use various stages of the filtration process to filter and separate the final substance from the equipment.

● It should hold all the quality and standard features as per the industry requirements.

● The design should be cognizable, i.e., support easy and quick filtration.

● The material or the equipment element should be corrosion-free.

● It should help rapid fluid flow and consume less time, money, and effort. 

● The separator should assist fluid that is enriched with pH elements.

● The separator should perform a maximum number of impurities removal at a time, either solid or liquid, from the respective substance.

● The Coalescer Filter Separator should have an extended working life. 

● It should extract the fluid with less than 5mg/m3 residuals.

Types of Coalescer Filter Separators 

There are two essential kinds of coalescers used in the business – electrostatic and mechanical. 

Electrostatic Coalescers 

Electrostatic Coalescers

An electrostatic coalescer uses frail electric charges to pull in water particles to the surface, where they go through the collection. 

Electrostatic coalescers use electric charges (DC or AC, or a mix of both) to incite a blend of fluid atoms onto the surface of a collection tank. They accommodate water-hydrocarbon emulsions and are broadly utilized in offshore creation platforms. The electrostatic charges help destabilize the emulsion by expanding the size of the atoms, making them fall to the bottom of the tank. 

Mechanical Coalescers 

The mechanical coalescer is the transcendent type used in the oil and gas industry and petrochemical plants everywhere globally. 

A mechanical coalescer that FCPL deals with comprises exemplary cross-section, fiberglass media, or Nonwoven Polyester/Polypropylene with oil and water repellency or wrap round arrangement. The fluid or vapor goes through the filters, where the fibers catch the water drops. These channels can be used after for fluid-fluid partition and fluid-gas division. 

Liquid coalescer

 Liquid coalescer is utilized to divide hydrocarbon from water, similar to oil expulsion from produced water and water expulsion from aviation fuel, gas, and diesel. 

Mechanical coalescers use a progression of baffle walls or mixing channels to isolate water/hydrocarbon condensates from emulsions and combine them into bigger atoms. A typical application is for water separation from liquid hydrocarbons or natural/ petroleum gas.

What Contaminants will Coalescer Filter Separators Remove?

As the name reflects, a typical Coalescer Filter Separator eliminates oil and water from the useable substances. Here is a list of common contaminants removed by the coalescer filter.

  • Condensates
  • Compressor Lube Oils
  • Amines & Glycols
  •  Water
  • Oil
  •  Brines
  • Well Stimulation chemicals
  • Completion Fluids

Likewise, coalescing filters eliminate potent toxins like dirt, residue, and rust from compacted and compressed air systems. These particles are forever caught in the filter element, confining the stream and hindering and blocking the filter media. So the volume, effectiveness, and level of contamination of the approaching air help decide the valuable existence of the filter channel component.

What is the Best Material for Coalescer Filter Separator Housing?

Coalescer Filter Separator Housing is one of the most significant parts of the Filter Separator. And that’s why materials that are used in this subpart of the equipment have to be thoroughly quality checked.

There are numerous variations in materials available to construct a coalescer Filter Separator Housing device. Some of the generally used materials are:

● Aluminum

● Stainless steel 

● Monel

● Copper

● Nickel

How and where a coalescing filter channel is introduced can affect the overall operating expense and machine performance. Specialists suggest installing a prefilter, like a 3-micron unit, to eliminate as many of the particles possible to increase the life of the coalescing filter.

If the compressed air in a cycle has different prerequisites in various circuits, install coalescing filters in utilization areas that demand clean air. This process saves money in the long run. Uniting filter channels will make a 2-6 psi drop downstream, so calculate the compressing factor into sizing and selection. When the critical factor drops across the channel increments to 8 to 10 psi, that is an early warning that the filter channel is approaching its end life and needs to be supplanted or replaced.

How long can a Coalescer Filter Separator Element Last? 

The ongoing life of a perfect Coalescer Filter Separator lasts until its material does not corrode. However, the life of a filter separator channel depends on various other features too. 

The best filter separator, which accords you a considerable amount of purified substance done at a point, has a higher chance of lasting more and providing you with worthy and efficient products.
