Produced Water Management with HRT

The oil and gas exploration industry is under pressure to address mounting water management challenges. Factors like limited resources at sites, water intensive unconventional plays, ... and excessive transportation and disposal costs ... all impinge on economics. An ever-changing regulatory environment combined with demands from the public sector for conservation and sustainability has put water management at the forefront of the industry.

Produced water streams must be treated prior to disposal, reinjection, or reuse. Effective hydrocarbon recovery and solids removal from produced steams is critical. Delivering reliable, stable operations enhances performance while addressing the health and safety of surrounding communities.


Liquid Aerosol Removal Demonstratation

The challenge associated with conventional separation mechanisms is that they depend on capturing the droplets through impaction of the droplet on a separation medium (such a wire mesh or filter media). As the droplets become smaller, the boundary layers around such media increase in dimension to the point that the droplets are much more likely to move around the fiber rather than collide into it.  The capture of such fine droplets, then, requires advances in technology to reduce such boundary layers, as well as create additional mechanisms for droplet capture.

Pentair's 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. The high fluid velocities at the circumference of the cylindrical element require the cylindrical elements to be spaced further apart. Apex® elements do not have to be spaced as far apart allowing the same flows to be handled in a smaller vessel, implying lower capital costs.

How fast can I get my separator vessel?

The timeline to get your separator vessel begins when you submit your purchase order. From that time, it depends if you are purchasing a new vessel to a certain specification or if you are renting a vessel that is currently in stock. A rental can often be deployed within 48-72 hours from the time the purchase order is submitted IF it is in stock. A new capital purchase really depends on specifications, application and need. Please contact us for more information.

Each one of Pentair's media are specifically engineered to provide efficient separations where purity is critical in process fluid, chemical and water filtration applications. They are designed to maximize efficiency, dirt holding capacity and chemical compatibility while assuring negligible contribution of extracted materials and the absence of fiber shedding.

HYBRID
Hybrid is composed of cellulose fibers and synthetic microfibers. This combination provides filter media with unique properties for a wide variety of applications. It combines the chemical compatibility, strength and microfiber properties of synthetic fibers with the cost-effectiveness of cellulose fibers in a single media. As a result, the media provides significantly lower clean pressure drop, higher contaminant capacity and longer element life when compared to wound string, wound sock or molded tubular elements at the same fluid cleanliness levels.


NEXCEL
Delivering performance at superior cost savings relative to other media types, NEXCEL separation media is composed of natural fibers (cellulose) cross-linked with a proprietary polymeric medium used to both coat and adhere adjoining fibers, creating a fixed pore matrix. This combination provides filter media with unique properties for a wide variety of applications. The proprietary formulation of NEXCEL provides significant advantages to conventional cellulose or pleated paper media; Primary among these advantages are the absence of media swelling in the presence of water, allowing NEXCEL to be used in hydrocarbon service, aqueous service and mixed aqueous / hydrocarbon streams.

NEXCEL is the preferred solution for mixed aqueous / hydrocarbon streams such as refinery amine service (which contains trace hydrocarbon; 5 – 5,000 ppm) and intermediate refinery fuel streams (diesel, kerosene and naphtha) where free water is present. These streams are often problematic for both conventional pleated paper as well as polypropylene media as conventional pleated paper may experience swelling concerns in the presence of water and polypropylene may experience swelling concerns in the presence of hydrocarbons. Additionally, NEXCEL media contains no surface sizing treatments eliminating the possibility of chemical leaching and foaming often attributed to these components.

POLYFORM
Polyform is composed of polypropylene micro-fibers thermally cross-linked to adhere adjoining fibers, creating a fixed pore matrix. This media design provides unique properties for a wide variety of applications. The formulation provides significant advantages where use of a chemically inert material is preferred. It is the preferred solution for separations requiring the absence of extractable ions or other chemical species and in streams of high chemical reactivity at moderate to low temperatures.


NEUTRAFORM
Neutraform media is composed of polyethylene sheathed, polyester core micro-fibers thermally cross-linked to adhere adjoining fibers, creating a fixed pore matrix. This media design provides filter media with unique properties for a wide variety of applications. The formulation of Neutraform provides significant advantages where use of a chemically inert material is preferred. It is is the preferred solution for separations requiring the absence of extractable ions or other chemical species and in streams of high chemical reactivity (e.g. – sulfuric acid, strong bases, strong oxidizers, etc.) at moderate to low temperatures.

PURACEL
Puracel is composed of pure, binderless cellulose. This media design provides filter media with unique properties for high purity applications. The formulation of Puracel provides significant advantages where use of a chemically inert, food grade material is preferred. Puracel is the preferred solution for separations requiring the absence of extractable ions or other chemical species and in food contact streams. Applications include water based fluids, edible oils and ethylene oxide filtration.


POLYTHERM
Polytherm is composed of polyamide microfibers thermally cross-linked to adhere adjoining fibers, creating a fixed pore matrix. This media design provides filter media with unique properties for high temperature applications. The formulation of Polytherm provides significant advantages where use of a thermally inert material is preferred. Polytherm is the preferred solution for separations requiring the high temperatures coupled with high solids levels. Applications include hydroprocessing feed filtration of heavy feeds (e.g. – resid, atmospheric bottoms, vacuum bottoms, etc).

THERMAFORM
Thermaform is composed of polyaramide microfibers thermally cross-linked to adhere adjoining fibers, creating a fixed pore matrix. This media design provides filter media with unique properties for thermally demanding applications. The formulation of Thermaform provides significant advantages where use of a thermally inert material is preferred. Thermaform is the preferred solution for separations requiring the high temperatures coupled with high solids levels. Applications include hydroprocessing feed filtration of heavy feeds (e.g. – resid, atmospheric bottoms, vacuum bottoms, etc) and applications employing high temperature steam.

DEXTRA
Dextra media delivers superior fluid quality and clarity relative to other media types. The media is composed of natural fibers (cellulose) and diatomaceous earth cross-linked with a proprietary polymeric medium used to both coat and adhere adjoining fibers, creating a fixed pore organic / inorganic matrix. This combination provides filter media with unique properties for a wide variety of applications. The proprietary formulation of Dextra provides significant advantages to conventional media for removal of very fine suspended solids and for fluid clarification; Primary among these advantages is the incorporation of diatomaceous earth, dramatically increasing available surface area and providing a system of micro- and nano-channels to adsorb fine solids and retain reformable gels. Dextra is the preferred solution for applications requiring high levels of fluid clarity and chemically inert media.
