The shale shakers performance can be easily observed, all aspects of its operation are visible. Shale shakers provide the advantage of not degrading soft or friable cuttings. When well operated and maintained,shale shakers can produce a relatively dry cuttings discharge.

In unweighted muds, the shale shaker’s main role is to remove as much solids as possible and reduce the solids loading to the downstream hydrocyclones and centrifuges to improve their efficiency. In muds containing solid weighting agents such as barite, the shale shaker is the primary solids removal device. It is usually relied upon to remove all drilled cuttings coarser than the weighting material. Downstream equipment will often remove too much valuable weighting material.Enough shakers should be installed to process the entire circulating rate with the goal of removing as many drilled cuttings as economically feasible. Given the importance of the shale shaker, the most efficient

shakers and screens should be selected to achieve optimum economic performance of the solids control system.

Shaker performance is a function of:

• Vibration pattern
• Vibration dynamics
• Deck size and configuration
• Shaker screen characteristics
• Mud rheology (plastic viscosity)
• Solids loading rate (penetration rate, hole diameter)

The impact of each is discussed in detail in this chapter. Guidelines for shaker and screen selection are also provided.Simply stated, a shale shaker works by channelling mud and solids onto vibrating screens. The mud and fine solids pass through the screens and return to the active system. Solids coarser than the screen openings are conveyed off the screen by the vibratory motion of the shaker. The shaker is the only solids removal device that makes a separation based on physical particle size. Hydrocyclones and centrifuges separate solids based on differences in their relative mass.

Mechanical sealing for centrifugal pump

Centrifugal pump is the regular pump use for solids control system and drilling oil system,GN solids control try supply reliable pump to every client

Mechanical seal as important point to decide pump’s quality and service life,was pay attentioned by GN solids control

The mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.

When sealing a centrifugal pump, the challenge is to allow a rotating shaft to enter the ‘wet’ area of the pump, without allowing large volumes of pressurized fluid to escape.

To address this challenge there needs to be a seal between the shaft and the pump housing that can contain the pressure of the process being pumped and withstand the friction caused by the shaft rotating.

Here we compare two different way

Traditional method

Gland packing is still commonly used in many applications, however increasingly users are adopting mechanical seals for the following reasons:;

• The friction of the shaft rotating wears away at the packing over time, which leads to increased leakage until the packing is adjusted or re-packed.
• The friction of the shaft also means that packing also needs to be flushed with large volumes of water in order to keep it cool.
• Packing needs to press against the shaft in order to reduce leakage – this means that the pump needs more drive power to turn the shaft, wasting energy.
• Because packing needs to contact the shaft it will eventually wear a groove into it, which can be costly to repair or replace.

Why choose mechanical sealing

• No “visible” leak – seals do leak vapour as the fluid film on the faces reaches the atmospheric side of the seal faces.
  • This would approximate to 1/2 teaspoon a day at normal operating pressures and temperatures, if it were captured and condensed.
• Modern cartridge seal designs do not damage the pump shaft or sleeve.
• Day to day maintenance is reduced as seals have inboard springs which make them self-adjusting as the faces wear.
• Seals have lightly loaded faces which consume less power than gland packing.
• Bearing contamination is reduced in normal operation as the lubricant does not become affected by seal leakage and wash out.
• Plant equipment also suffers less from corrosion if the product is contained in the pump.
• Vacuum can also be sealed with this technology, a problem for packing as air was drawn into the pump.
• Less wasted product will save money, even water is an expensive commodity and less clean up of the area will be needed.

To give client’s suitable product,GN solids control will always develop the design and improve service

GN will join ADIPEC 13-16 November 2017 (the Abu Dhabi International Petroleum Exhibition and Conference)

Booth Number:10250

We can meet at Abu Dhabi and disscuss how to make solids control more efficiency and provide better service

Our new product plan and supply advice will discuss with you at ADIPEC

Recently, GN received many good comment on theshaker screen performance on site. also, it means the the developing on screen fabrication technology.
For now, GN’s shaker screen facility is able to fabricate the replacement screen for almost all the famous brand in the industry. freshed developing composite frame screen can proved onsite for working time 300~700 hours according to working condition with various mud composition, temperature etc.
To keep reliable quality, GN also designed strong package box for the screen. From screen to packing, both give a magnificent and classy impression. The package is provide with or without GN Logo for clients’ resale purpose.

ADIPEC is one of the world’s most influential events for the oil and gas industry. As a premium exhibition and conference platform, ADIPEC hosts hundreds of speakers, thousands of exhibiting companies and tens of thousands of trade professionals from around the world.

The Abu Dhabi International Petroleum Exhibition and Conference (ADIPEC) 2017 will be the premier meeting place for energy ministers and C-level executives from the world’s oil and gas giants that will convene under the theme: “Forging Ties, Driving Growth.” It is expected that there will be more than 200+ sessions across the Technical and Non-technical conferences.

ADIPEC’s inaugural 2016 Security In Energy Conference brought together for the very first time, cyber and critical infrastructure security experts and oil and gas executives to discuss the real life security threats and challenges facing the oil and gas industry.

Offshore & Marine at the Abu Dhabi International Petroleum Exhibition and Conference (ADIPEC) has rapidly become a must-visit zone. The next – third – edition of the co-located annual ADIPEC event builds on the success of previous editions, attracting more exhibitors, more visitors and a larger conference stream.

The four-day event includes a waterfront vessel display area, over 8,000 sqm of exhibition space housing more than 150 exhibiting companies with access to 15,000+ professionals from around the world, plus a dedicated Conference theatre for a mixture of strategic and technical sessions.

Hope GN solids control and every visiter have a good time at ADIPEC2017
