CYCLOTECH MC Series desanding hydrocyclone technologies


CYCLOTECH MC Series desanding hydrocyclone technologies remove solids from produced water,seawater, and liquid hydrocarbon streams to meet the demanding environmental and physical requirements of the upstream oil and gas industry. The technologies’ mosr common applications are for produced water systems,protection of downstream equipment,and reinjection systems.

Overview – CYCLOTECH MC Series desanding hydrocyclone technologies
CYCLOTECH* MC Series* desanding hydrocyclone technologies remove solids from produced water, seawater, and liquid hydrocarbon streams to meet the demanding environmental and physical requirements of the upstream oil and gas industry. The technologies’ most common applications are for produced water systems, protection of downstream equipment, and reinjection systems.

ADVANTAGES
        - Broad range of solids sizes managed from 2 um to 15 mm
        - No moving parts for enhanced reliability
        - No need for duty or standby operation
        - High sand removal efficiency regardless of hydrocyclone diameter
        - Robust makeup materials stand up to erosion

Application of CYCLOTECH MC Series desanding hydrocyclone technologies
MC Series technologies have no moving parts and achieve solid-liquid separation using a pressure drop across the unit. Slurry is directed into the inlet section of the liner via a tangential inlet port. This, together with a narrow cyclone diameter, causes the fluid to spin at high velocity, creating a high-g radial acceleration field. The denser-phase solid particles are forced outward to the hydrocyclone inner wall. Here, through internal hydrodynamic forces, the solids are ejected from the apex of the cyclone while the liquid exits via an axial port adjacent to the inlet. The separated solids are collected in a solids accumulator, which can be periodically purged on line without interruption to the hydrocyclone operation. This purging eliminates the need for duty or standby operation.

Schlumberger produced water and sand management technologies provide compact, targeted, robust, and flexible solutions that meet discharge requirements for customers’ specific applications.

CYCLOTECH WDC Series Wellhead desanding cyclone technologies


CYCLOTECH WDC series wellhead desanding cyclone technologies can be applied to a wide range of gas/liquid ratios.Deploying WDC Series technologies enables determining the potential range of actual wellhead flowing conditions,designing the cyclone geometry to suit, and predecting seperation performance and cyclone pressure drop.

Overview – CYCLOTECH WDC Series Wellhead desanding cyclone technologies
- Customized new-generation solids separation technology
Schlumberger wellhead and production desanding cyclones represent a new generation of solids separation technology specifically designed for multiphase wellstreams. These custom-engineered technologies use the presence of the gas phase to improve rather than detract from separation performance.Therefore, CYCLOTECH WDC Series Wellhead desanding cyclone has an important role in this part.

Advantages
         - Improved reliability through protecting chokes, flow lines, and manifolds from erosion as well as downstream equipment from erosion, corrosion, and blockage
         - Reduced production separator sand jetting requirements
         - Increased production above sand‑free rates

Application of CYCLOTECH WDC Series Wellhead desanding cyclone technologies
WDC Series technologies have no moving parts and separate solids from multiphase well streams by density differential, using only a small pressure drop across the cyclone. A solids-laden multiphase flow is directed into the inlet section of the cyclone via a tangential inlet port. This causes the fluid to spin at high velocity, creating a high-g radial acceleration field. The dense-phase solid particles are forced outward to the hydrocyclone inner wall. There, through internal hydrodynamic forces, solids are ejected from the apex of the cyclone while the rest of the multiphase flow exits via an axial port that is adjacent to the inlet. The separated solids are collected in a separate solids accumulator, which can be periodically purged on line without interrupting the hydrocyclone operation. This eliminates the need for duty or standby operation.

CYCLOTECH SCARPA Cyclonic separation technologies


CYCLOTECH SCARPA Cyclonic separation technologies removes sand and other solids from a production seperator on either a continous or batch basis.The modular system can be retrofitted into existing seperators as well as be incorporated into new-build plants.The SCARPA system can convert a three-phase seperator into a true four-phase seperator or a two-phase seperator into a true-phase seperator.The system was developed for topside and subsea production seperators.

Overview – CYCLOTECH SCARPA Cyclonic separation technologies
CYCLOTECH SCARPA Cyclonic separation technologies is one of the most important machines.Whether produced from the reservoir or introduced through well servicing, produced solids are a growing concern for upstream operators. If left uncontrolled, solids production can cause major flow assurance issues.

The keys to successful topside sand handling is flexibility in process design, technology selection, and  Sand production is unpredictable, and the management solution is never universal. Sand management almost always includes factors such as accumulation, fluidization, transportation, cleaning, and disposal—all of which require careful consideration.

Our sand management technologies and sophisticated process design methodologies provide you with the tools to optimize sand management for every application, including multiphase, in-separator and liquid phase.



- Sand receiving and cleaning systems
We offer a range of CYCLOTECH separation technologies that clean sand to such low oil concentrations that the cleaned material can be pretreated prior to shipment to shore or reinjected into the reservoir.

- CYCLOTECH SCARPA eductive sand jetting system
CYCLOTECH SCARPA eductive sand jetting system is a sand-conveying and -removing apparatus that removes sand and other solids from a production separator on a continuous or batch basis. The modular system can be used to retrofit existing separators or incorporated into new-build plants.

- Advantages
         - Decreases pumped flow rate requirement
         - Produces no effect on oil-water separation performance
         - Maximizes separator water pad residence time
         - Eliminates sand carryover to water and oil outlet streams
         - Limits residue sand to less than 5% of total
         - Reduces potential erosion and corrosion of separator
         - Eases sand removal as it has less time to solidify in place
         - Minimizes and controls sand concentrations in outlet pipe work, optimizing the availability and performance of downstream sand-handling equipment
         - Limits the size and complexity of the downstream receiving equipment
         - Minimizes risk of blockage

Application of  CYCLOTECH SCARPA Cyclonic separation technologies
The SCARPA system creates a low-velocity flow that runs along the bottom of the separator through the use of specialized eductor nozzles. An eductor is an established solids-conveyance device that uses a small flow of high-pressure motive fluid to pump a higher-flow, lower-pressure fluid. The eductors’ format of suction from behind and discharge in front enables hydraulic balancing to generate a dynamic layer of water of comparatively low velocity along the bottom of a separator. Such hydraulic balancing prevents sand from settling and acts as an effective solids-transport system with minimal radial (vertical) disturbance.

This hydraulic conveyor can be directed toward one or more discharge outlet nozzles at the bottom of the separator and then routed to the suction of an external CYCLOTECH Sandscape* solids conveyance and concentration control system, which controls ejection of solids from the separator.

MOZLEY Wellhead Desander- Solids removal system

Consisting of single or multiple cyclone inserts housed inside a vessel operating at the appropriate well head design pressure,MOZLEY Wellhead Desander solids removal systems are used at the production wellhead.These efficient units protect downstream equipment from mechanical damage and erosion. They also prevent partial blocking and settlement of sand in seperators that lead to a reduction in capacity.

Overview – MOZLEY Wellhead Desander- Solids removal system
- Eight times longer lifespan in aggressive multiphase well fluid environments
The MOZLEY Wellhead Desander Solids removal system provides unmatched performance and durability in one of the most difficult and important solids management applications: sand removal from wellhead fluids. To provide the most effective desanding and offer the best protection for equipment downstream of the wellhead, choosing the best hydrocylone configuration is key.

- Protect process equipment erosion and downtime
MOZLEY Wellhead Desander solids removal systems mitigate the effects of sand production, such as mechanical damage to equipment; erosion of pumps, valves, chokes, and flowlines; and reduction in separator capacity due to settlement of sand. The systems use a simple, compact design based on solid-liquid hydrocyclones to separate solids from both the gas and liquid components of well fluids. The hydrocyclone housings can be customized to handle high wellstream pressures and widely varying feed conditions.

- Choose fit-for-purpose solids removal at the wellhead
Selection of the hydrocyclone internals depends on the range of viscosities and specific gravities of the well fluids and the operating gas/liquid ratios. Proper selection ensures optimal performance throughout the operating ranges and provides equipment downstream of the desanding system with superior wear protection.

MOZLEY Wellhead Desander systems employ solid liners made of special silicon nitride ceramic material developed expressly for use in hydrocyclone liners. These liners last eight times longer than competitive alumina ceramic desanders or ceramic-coated hydrocyclones. This provides a reduction of downtime stemming from hydrocyclone wear and replacement, which lowers operating expense. Additionally, the liners are self-cleaning, and slugging of solids will not plug them, further reducing downtime and lowering opex.

- Use multiple small hydrocyclones for greater efficiency
The core of the system is the hydrocyclone liner. Use of extensively enhanced geometrical features and specifically selected construction materials maximizes performance and minimizes erosion in aggressive multiphase well fluid environments. Multiple hydrocyclones are typically installed within a pressure vessel, providing significantly greater efficiency and operating life compared with a large-diameter single hydrocyclone or ceramic-coated metal inserts.
 
These hydrocyclone clusters cope with the surges of gas and liquid flows much better than large-diameter single hydrocyclones, operating instantaneously to achieve solids separation. With a single hydrocyclone, any high-concentration slugs of solids can potentially block the inlet and underflow, preventing flow.

For less-demanding separation duties, a large-diameter single liner—typically 10-in diameter or greater—can be used. Packaged in a vessel, the single-liner design can reduce costs compared with multiple liners.

Application of MOZLEY Wellhead Desander- Solids removal system
The cyclone inserts of the MOZLEY Wellhead Desander system are specifically designed for each application using proprietary computer simulations. The silicon nitride ceramics developed expressly for used in the solid ceramic hydrocyclone liners deliver 8 times greater wear resistance, as compared with standard grades of ceramic liners or ceramic-coated hydrocyclones. Wellstream fluids enter the cyclone tangential inlet, which forces the mixture to spin and in turn causes the gas to disengage quickly. Both gas and liquids migrate toward the center of the cyclone, as a reduction in cyclone diameter accelerates the fluid while concurrently generating strong centrifugal forces. The gas and liquid flow then reverses and moves upward toward the overflow vortex finder. Solids are separated from the gas and liquid, forced toward the cyclone wall, where they travel down the length of the conical section of the cyclone in a spiral pattern to the solids outlet. The separated solids fall through into the accumulator vessel situated on the underflow of the wellhead desander, or a continuous hydrotransport device can be used. The accumulator vessel is periodically isolated and collected solids are flushed out. The wellhead desander itself remains online and operating while the accumulator is being cleaned.

Tri-Star Group of Companies is the Leading Global Manufacturer and Supplier of Best in Class Bolts and Nuts, Cable Support Systems, Cathodic Protection Systems and Hydraulic Bolt Tensioning and Torquing Tools and Services to the worldwide Energy & Infrastructure sectors.

The Tri-Star Industries Group started business in the late 70’s, trading and manufacturing bolts and nuts. From humble beginnings, the Group has made significant progress to become a renowned manufacturer of fluoropolymer coated bolts and nuts, cable support systems, cathodic protection products & services and hydraulic bolt tensioning & torquing products & services for the Oil, Gas, Power, Petrochemical, Marine and Infrastructure Industries around the world.


Overview – Tristar Bolts and Nuts
Fundamentals of Bolts and Nuts
In contrast to a screw, a bolt is typically accompanied with a nut and a washer in order to act as a fastener. As you tighten the nut, it forces the items you’re attaching towards one other, pushing the washer against one and tugging the bolt head against the other. Material, finish, size, and thread type must all be considered when matching a nut and washer to a bolt.

Materials and finishes for bolts, nuts, and washers
Steel is a popular material for nuts and bolts, however if they will be exposed to moisture or pressure-treated timber, which may corrode steel fasteners, ordinary steel fasteners need a corrosion-resistant coating. There are many popular DIY finishes.
         - Zinc-plated bolts are corrosion resistant but should only be used inside. The finish is often thin, will not withstand the weather outside, and is not suitable for use with pressure-treated timber. Yellow zinc or yellow dichromate provides a layer that covers the zinc plating for increased corrosion resistance, but it does not offer protection for outdoor usage or when used with pressure-treated timber.
         - Hot-dipped galvanized nuts, bolts, and washers are more corrosion resistant. These fasteners are designed for outdoor usage and are compatible with pressure-treated timber.
         - Powder-coated paint finishes are intended for usage on the inside.
         - Black phosphate is a coating that allows for excellent paint adherence.
         - The corrosion resistance of epoxy and other coatings varies based on the kind of coating. Specific applications should be found in the product information.
         - Stainless steel has excellent corrosion resistance. Stainless steel nuts, bolts, and washers are often used in exterior projects and when working with pressure-treated timber
         - Because of their enhanced strength, hardened steel bolts are often utilized in automobile assembly.

Sizes of Bolts, Nuts, and Washers
Bolt, nut, and washer sizes will be specified in metric millimeters (mm) or standard or Society of Automotive Engineers (SAE) inches (in). A bolt’s diameter is typically the outer diameter of the threads. Compare the outside diameter of a bolt to the interior diameter of a nut and washer. Diameters of 1/4 inch and less are denoted by a # and a whole number in SAE nuts and bolts (a bolt with a main diameter of 3/16 inch is a #10 bolt). Smaller numbers represent smaller dimensions.

The distance between the end of the bolt and the underside of the bolt head, also known as the bearing surface, is typically indicated by length.

Thread Types for Bolts, Nuts, and Washers
Nuts and bolts are either coarsely or finely threaded. Match the threading of a nut to the threading of a bolt.
           - The most prevalent are coarse-threaded nuts and bolts, which have greater space between the threads. They’ll be identified by a higher  thread pitch. Because coarse-threaded bolts and nuts are less prone to get stuck or cross-threaded, they may be secured more rapidly.
            - Fine-threaded nuts and bolts with lower thread pitches have fewer thread gaps, resulting in a tight, firm grip. Vibrations are less likely to dislodge a nut on a fine-threaded bolt but installing or removing the nut will take longer.

    - Load Indicating Fasteners
         Maxbolt Load Indicating Fastener
Maxbolt load indicating fasteners continuously displays the amount of tension in a bolt or stud. They offer a simple method for accurate joint assembly, and it is the only product available (for most applications) that will continuously clamping force while the fastener is in service. Maxbolt load indicating fasteners are manufactured by inserting extremely accurate and durable load monitoring devices into high quality bolts and studs. Now, even inexperienced workers can complete complex assemblies with full assurance that fasteners are at the proper tension. Maxbolt also provide in-service monitoring which will warn users of any loosening in order to avoid premature wear, unnecessary downtime, or catastrophic failure.Our Maxbolt load indicating fasteners comes in various shapes and sizes. It can be manufactured from standard ANSI materials to exotic materials.

SPC4 Load Indicating Fasteners
        The SPCA load indicating fastener allows user to install a bolted assembly with confidence. The user can constantly monitor the clamp load of any SPC4 bolted joint whether static or dynamic, by attaching a probe to the datum disc located on the end of the fastener and reading the value on a hand held  battery powered digital monitor. Optional data gathering and storage of the bolted joint are available.The integrity of a bolted joint is jeopardized when fasteners lose their tension. This loss of clamping force begins during assembly due to elastic interactions and joint relaxation. Self-loosening continues when the joint is put in service due to vibrations, temperature changes, shocks, etc. The SPC4 joint allows the end-user to retighten only the bolts or studs that have lost their clamp load resulting in a tremendous saving of maintenance time, money and replacement parts. For a minimal investment, the SPC5 offers maximum joint integrity with optimum performance.
