Pentair Filtration Solutions, LLC

High performance separation system for ethylene industry - Oil, Gas & Refineries

Fundamental building block chemical used in the production chain of polyethylene, PVC, styrene, ethylene glycol, vinyl acetate, linear ∂-olefins and a host of other chemical products. Eliminate hydrocarbons in Quench Water system, minimize fouling, provide greater system reliability, lower maintenance, lower energy costs. Quench water contains emulsified heavy aromatic hydrocarbon (SG = 0.975). Cracked hydrocarbons are extremely reactive. Polymerization leads to fouling of quench system, exchangers, dilution steam generator. Fouling reduces plant profitability and on-stream reliability.


LIQUISEP technology was developed to address the inherent deficiencies of conventional coalescers, making it possible to remove essentially all immiscible water dispersions from hydrocarbon process streams. The LIQUISEP technology overcomes the limitations of conventional separators, vane pack coalescers, wire mesh coalescers and even “high efficiency” mesh pads and filter separators, achieving superior separations under demanding conditions.

LIQUISEP technology makes use of proprietary LIQUIFORM™ media and our patented APEX element design to intercept entrained droplets of even sub-micron geometries and effectively remove them from the process. The high surface energy LIQUIFORM media effectively disrupts the stabilized water droplets, allowing for efficient capture. Additionally, the fiber geometries are specifically designed to promote accumulation and removal of free water from the process stream. The APEX element design works in concert with the media technology promoting uniform fluid flow, while minimizing the potential for turbulence and high fluid velocities which might interfere with water removal from the process stream.

LIQUISEP technology protects critical assets from water contamination and the salts, acids and bases which it may contain. Application of the LIQUISEP technology allows optimized performance of downstream treaters, salt beds, exchangers and reactors while assuring the elimination of haze from finished products.


ProcessOR provides high performance solid-liquid separation. Solid contaminants range from sub-micron particulates as small as viruses to particles several hundred microns in size. The liquids range from aqueous to hydrocarbon systems with viscosities up to 60,000 cP. Pentair Porous Media’s sold-liquid technolgies have been applied in the oil and gas, refinery, chemical, petrochemical and power industries.

ProcessOR's standard elements are cored, however, you may upgrade to our COMPAX coreless element technology. The COMPAX coreless element flows from the outside-to-the-inside. This element is offered with an extended surface area media configuration utilizing our proprietary NexCel media. The media provides robust performance in glycol and aqueous service as well as hydrocarbon applications. The COMPAX coreless element designs currently being used by a large number of gas plants and hydrocarbon processes due to the superior operating economics and ergonomic advantages.
