Clean, aerosol-free gas is critical to equipment reliability and the economic efficiency of gas processing, petroleum refining, and chemical processing applications. Pall SepraSol™ liquid/gas coalescers remove liquids and solids from contaminated gases with high efficiency and reduce operating and maintenance costs.
SepraSol™ liquid/gas coalescers come with the patented oleophobic/hydrophobic treatment that lowers the medium's surface energy and promotes rapid drainage of the coalesced liquids. It enhances the capacity for liquid challenges and results in improved performance allowing for smaller systems, lower pressure drop, and improved ability to recover from liquid slugs.
Pall’s SepraSol liquid/gas coalescers eliminate virtually all solids and liquids in a gas stream. Downstream liquid levels are as low as 0.003 ppmw1, and the solids removal rating is 0.3 micron (μm) (99.99% efficiency)2
1 Test conditions used to measure efficiency area are as follows:
Flow rate: 900 SCF/minute per 30 in. element at 37.8°C (100°F) and 6.9 bar (100 psig)
Liquid inlet: 50 ppmw oil

Pall Corporation applies a patented oleophobic/hydrophobic chemical treatment on all of its SepraSol liquid/gas coalescers. This allows the coalescers to operate at a lower saturated pressure drop. As shown in Figure 1, a small difference in saturated pressure drop can result in significant savings in operating costs.
About Coalescer Efficiency Ratings
The measurement of the efficiency and the pressure drop of a coalescer should reflect operating conditions. Many manufacturers of coalescers measure efficiency using the dioctyl phthalate (DOP) test. The DOP test was not originally designed to measure the performance of a coalescer under operating conditions seen in the oil and gas industry. Rather, the DOP test is performed under the following conditions:
Pall has developed a test called the Liquid Aerosol Separation Efficiency (LASE) Test to specially measure the performance of a coalescer under operating conditions. The table below compares the LASE and the DOP tests. For further details on the LASE test, see Pall literature GAS-4300b, "Recent Developments in Performance Ratings of Gas/Liquid Coalescers ."
