High performance separation system for glycol dehydration - Oil, Gas & Refineries

Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). It is the most common and economic means of water removal from these streams.Glycols typically seen in industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and tetraethylene glycol (TREG). TEG is the most commonly used glycol in industry.

HRT technology provides petroleum producers, refiners and gas processors dramatically improved solids control and hydrocarbon recovery from process water streams relative to that achievable through implementation of conventional residence tanks or separators.

Residence tanks are ineffective at separating emulsified hydrocarbon from aqueous streams, allowing essentially all dispersed hydrocarbon to pass through. Likewise, conventional methods such as walnut shell filters or induced gas / dissolved air flotation (IGF or DAF) are limited to applications with less than 200-300 ppm oil and under the best of circumstances are typically 90% - 95% effective.

By contrast, the HRT technology was developed to remove solids as fine as 1 micron to 99.98% efficiency if desired and intercept and recover even stable emulsified hydrocarbons, allowing essentially zero free hydrocarbons to pass through. Consequently, the HRT technology provides vast improvements in the treated water quality attainable in various produced or process water systems.

UltiSep sets a new standard in high-performance gas/liquid separation. UltiSep utilizes Pentair Porous Media’s proprietary microfiber media technology and patented APEX element design. These technologies are applied for high efficiency bulk liquid and aerosol removal from process streams. APEX technology affords the user an unprecedented ability to reduce liquid carryover and pressure drop while providing smaller footprints and lower capital costs. UltiSep housing configurations are designed via the use of Computational Fluid Dynamics (CFD) and other proprietary computer models that ensure accurate and complimentary design in conjunction with APEX. The implementation of these technologies offers the ideal business model for value added and optimized systems.

UltiSep offers the ability to maximize operational profitability by minimizing entrained liquids in process gas streams. Eliminating liquid and solid carry-over minimizes process upsets and the corresponding issues associated with them, such as; product loss, fluid make-up, off-spec products, contamination in feed streams entering processes, emulsions, foaming, fouling, corrosion and mechanical wear.

UltiSep allows the removal of liquids ranging from bulk fluids to entrained droplets as small as a viral particle, improving operational efficiency and profitability.

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.
