Gas Coalescers Filters
Product Details:
The Pall SepraSol™ Plus Liquid/Gas Coalescer removes liquids and solids from high flow gas streams that contain high concentrations of liquids.
Pall Corporation’s staff of research scientists and engineers have designed these coalescers that change the way gas streams are conditioned.
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.
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

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 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.
