NGLs - Fractionation

There are two basic steps to the treatment of natural gas liquids in the natural gas stream. First, the liquids must be extracted from the natural gas. Second, these NGLs must be separated themselves, down to their base components, which include methane (CH⁴), ethane (C²H⁶), propane (C³H⁸) and butane (C⁴H¹⁰).

A few common contaminants in a natural gas stream include water, carbon dioxide (CO²) and hydrogen sulfide (H²S). Some of the substances which contaminate natural gas have economic value and are further processed or sold. A fully operational plant delivers pipeline-quality dry natural gas that can be used as fuel by residential, commercial and industrial consumers.

Extractive Separations - Polarex

Polarex, US Patent 8425663, an extractive separations technology provides gas processors, chemical manufacturers, and refiners dramatically improved separation of entrained and dissolved contaminants. It is designed to replace conventional water wash and solvent scrubbing towers.

Liquid/Liquid - LiquiSep

LiquiSep technology has been implemented specifically to help separate emulsions that are not separable by conventional coalescers. Conventional coalescers are unable to provide the degree clarity associated with LiquiSep technology due to the inability to capture and remove the most penetrating droplets that cause carry-over. LiquiSep can separate these dispersed and emulsified droplets from the hydrocarbon to practically non-detectable levels.

Particle/Liquid - ProcessOR

The ProcessOR is a superior separator vessel often used for particle/liquid filtration or separation. It is available to be delivered as a self-contained skid (pictured) or a stand-alone vessel. It is also available custom sized as a capital sale or as a turn-key rental, which is often available within days of the received order.

APEX

The Apex element is specifically intended to keep annular velocities constant across the entire height of the element. This is accomplished by introducing a gentle taper in the element, so that the annular space on the outside of the element gradually increased from the bottom to top, keeping pace with the external fluid flow as it exited the element.

Compax

Compared to conventional cartridge filters, COMPAX saves you money by lowering operating costs and reducing disposal costs. When comparing filters with the same efficiencies or Beta ratings, nothing outperforms the cost/performance value achieved with COMPAX.

V-MAX

V-MAX is a coreless filter that flows from the inside-to-outside like a bag filter but V-MAX technology can offer the same online life as a bag filter in a vessel that is roughly half the diameter. This is possible since the V-MAX design offers up to ten times the available filtration media in the same element envelope.
