Description
For more than 25 years, Pentair UltiSep technology featuring Pentair Apex separation media has enabled gas-processing facilities to achieve superior separation efficiency of aerosol contamination, leading to increased throughput and operational efficiencies. Building upon this legacy of separation expertise and industry-leading performance, Pentair has developed the next generation of liquid gas separation technology for midstream and downstream plants, Pentair Apex Zenith TM element filters.

Separation system efficiency is determined by the combination of gas velocity/flow rate, the amount of aerosol ingression in the gas, the operating pressure and internal element configuration. As the flow rate and/or liquid loading increase, efficient separation of liquids becomes more difficult. Pentair Apex Zenith coalescing element is enabled by our proprietary advanced media that delivers higher separation efficiencies at significantly elevated gas velocities and liquid concentrations with a reduced vessel envelope.

How An UltiSep Works

1) Wet gas containing both bulk liquids and liquid aerosol enters the UltiSep system through the lower nozzle into the bottom chamber of the vessel. This chamber is designed to allow bulk liquids to slow as the velocity of the gas slows and drop to the bottom of the chamber. Level controls and drain ports are located at the bottom of the lower chamber to remove bulk liquids.

2) Once bulk liquid fall out in the lower chamber, the “wet gas” or gas entrained with liquid aerosols moves up through the tubesheet into the elements themselves. The elements flow from in to out, and as the wet gas begins to exit the element, the specialized coalescing media captures these sub-mictron aerosols and holds them, combining them with other droplets until they are large enough to be drained

3) Liquid captured in the elements drains downward, dripping between elements to the bottom of the upper chamber. There, liquid is collected and another set of level controls and drain ports removes this coalesced liquid.

4) The elements are mounted on risers, keeping them out of this coalesced liquid so that they will never be submerged when the level controls are operating correctly.

5) Dry gas, removed of 99.97+ percent of all liquids exits the elements and moves upward, exiting near the top of the vessel.
