SepraSol™ Plus Liquid/Gas Coalescers

The SepraSol™ Plus Liquid/Gas Coalescer removes liquids and solids from high-flow gas streams that contain high concentrations of liquids. The SepraSol Plus media can process several times more liquid per unit area of media than conventional media and often eliminates the need for upstream bulk separation equipment like mist eliminators and vane separators.

Features: 

  • SepraSol Plus media pack
  • High-capacity large diameter element
  • Patented Oleophobic/Hydrophobic media treatment
  • High-effective filtration area

Description

The research scientists and engineers at Pall have designed these coalescers that change the way gas streams are conditioned.

 

Liquid Influent Concentration – the key to coalescer performance

 

One major reason why coalescers do not function properly in the field is because of an underestimation of the liquid influent concentration to the coalescer. Simply stated, the more liquid charged to a coalescer system, the more coalescer media is required. If the coalescer is challenged with too much liquid, significant quantities of liquid will become re-entrained in the effluent gas, and downstream equipment problems will continue to occur.

 

The Pall SepraSol Plus media is able to handle higher levels of liquid per unit area and requires significantly fewer cartridges to remove liquid and solids from gases. This is illustrated in Figure 1, which compares the SepraSol Plus liquid/gas coalescer with a conventional media pack. As the liquid load is increased, the number of cartridges required to remove the liquid also increases.

 

With conventional media packing, the cartridge requirement may become uneconomical once the liquid concentration gets above a few hundred ppmw. The SepraSol Plus liquid/gas coalescer economically removes liquids with a concentration in the thousands of ppmw, often eliminating the need for an upstream bulk separator.

 

Why choose SepraSol Plus Liquid/Gas Coalescers?

  • Lower operating and maintenance costs
  • High liquid removal per unit area
  • Fewer elements needed for a given gas flow rate
  • Lower saturated pressure drop
  • Quicker recovery from liquid slugs
  • Minimized vessel diameter due to fewer restrictions on annual velocity
  • Reduced need for an upstream bulk separator
  • Reduced capital and installation costs
  • Smaller space required for installation
  • Improved product quality and consistency

Product Highlights: 

  • Fewer element changeouts needed 
  • High solids removal efficiency 
  • Consistently high liquid removal efficiency
  • Reduced liquid losses
  • Optimum protection of downstream equipment

Performance

Coalescer Technical Information

 

The SepraSol Plus Liquid/Gas Coalescer – no longer just for polishing.

Before developing the SepraSol Plus liquid/gas coalescer, high-efficiency liquid/gas coalescers were used specifically for polishing.

 

Generally, if the liquid influent concentration was greater than a few hundred ppmw, a bulk separator such as a knock-out drum, mist eliminator, or vane separator was required upstream of the coalescer to remove large liquid droplets, and a coalescer would be used to remove the small droplets (less than 5 microns).

 

As demonstrated below in Figure 1, the SepraSol Plus liquid/gas coalescer can handle high liquid loads, often eliminating the need for upstream bulk removal equipment. In addition to the benefits of our media, the SepraSol Plus liquid/gas coalescer also includes features that have been Pall coalescer standards for many years.

 

Oleophobic/hydrophobic Treatment

 

All of Pall’s SepraSol and SepraSol Plus liquid/gas coalescers receive the patented oleophobic/hydrophobic treatment. Chemically treating the coalescer lowers the surface energy of the media and promotes rapid drainage of the coalesced liquids. This significantly increases the amount of liquid per square foot of media the coalescer can handle.

 

Added benefits to the chemical treatment include lower saturated pressure drop, which saves operating costs and rapid recovery from liquid slugs.

 

Figure 2 shows the effect of the benefits of both the oleophobic/hydrophobic treatment and the SepraSol Plus liquid/gas coalescer compared to a coalescer with conventional packing and no chemical treatment.

 

Note: Under the process conditions stated, the SepraSol Plus liquid/gas coalescer with chemical treatment requires a significantly smaller assembly under maximum liquid loading conditions than the untreated coalescer with the conventional pack design. Assembly diameter is directly related to the overall installation cost.

Applications

The SepraSol Plus media is supplied in a large flow, high-performance 6-inch diameter cartridge that can economically treat large gas flows in applications that require a high degree of protection from both solids and liquids, including:

  • Protecting compressors and turbines
  • Removing lubrication oil, water, and compressor wear products from effluent gas streams
  • Removing liquid aerosols from gases fed to amine sweetening and dehydration units to prevent foaming problems
  • Protecting desiccant and catalyst beds 
  • Minimizing solution losses downstream of gas purification process units
  • Cleaning dirty fuel gas to protect low Nox burners and fuel injection nozzles
  • Controlling injection well plugging during gas flooding
