Waste Water Cleaning Equipment
Jun 29

Oil and Gas Industry is changing its pace every year, from conventional drilling to unconventional drilling to pad drilling. So the industry traditional mud recycling system is gradually replaced by automatic, systematic and close-looped mud recycling system. More drilling contractors have equipped cutting dryers with their mud processing system. The cutting dryer can meet the environmental requirement and recover and recycle more material for reuse.

Recently we have supplier many key equipment to world’s drilling and solids control market especially in the Russian Market. We have supplied 6 units of

s, Mud cleaning system—2 systems, 6 units of Centrifugal pumps, 2 units of Centrifugal degasser, and our star equipment—4 units of our decant Centrifuge. We have find a serval good local distributor in the Russian Market to help us push our equipment, and this is one of the key marketing methods we use.

In the US Market, we have been pushing our new composite framed shale shaker screens have the follow features: the steel frame part is welded automatically by robot with higher strength and better quality conformity. The injection molded plastic is mixed with imported fiberglass and it can resists high temperature up to 140 degree, and it’s tougher, more endurable and can work under higher vibration G force. GN’s composite screens cover GN’S OEM screen, MI SWACO MONGOOSE, BRANDT VENOM, BRANDT KING COBRA, FSI, etc. GN can also customize the screens according to customer’s requirement. All the composite screens are repairable. Comparing to steel framed screens, the non blank area of composite framed screen is 10-20% more. And the composite frame is not easily to get rusted and can be stored up to 5 years.

That’s the brief introduction about GN’s new fully hydraulic drive decanter centrifuge. Welcome to visit www.gnsolidsamerica.com and please send your inquiries to cris.zhang@gnsolidscontrol.com

Comparing with other solids control equipment like the shale shaker, desander, desilter and other equipment, the decanter centrifuge clearly need more attention and more care during operation in order to make sure a good performance, especially on the 24*7 running jobsites.
As the leading manufacturer of solids control and waste management manufacturer in China, GN has been producing hundreds of decanter centrifuges and GN centrifuges are working all over the world, GN has following tips to share with the decanter centrifuge owners or operators.

a good choice of centrifuge

GN decanter centrifuge

1. Before confirming the model, collect as much as information including the those points: the jobsite condition, like the temperature, the end users’ special request like the EX standard (ExdIIBT4? IEC EX? ATEX or Gost?), the allowable max electric current, and electric specification of the jobsite(380V, 50HZ? 460V, 60HZ? 415V, 50HZ or others?). And try to collect as much information of the material to be treated, the largest particle size, the solids contents before treatment, and the allowable largest particle size and solids content after treatment. A right choice of decanter centrifuge is the precondition of its good performance. Those are GN Centrifuge Models for your reference.
2. Before installing and commissioning of the decanter centrifuge, read the user’s manual carefully and get a general idea of the specific model of decanter centrifuge and the control panel. Normally, the VFD controlled decanter centrifuge is more complicated to operate, the operator need to have both mechanical and electric knowledge to handle it, at least for operate it.
3. Assign a specific professional engineer or operator for each decanter centrifuge. His work is to observe the condition of the decanter centrifuge and discover any problem at the first time and solve it. Because the centrifuge is high speed running machine, and when the mud condition changed a bit, it affect the performance and the centrifuge service life.
4. Lubricate the centrifuge on time, especially the bearings. Like GNLW363CG decanter centrifuge, the bearings are original SKF bearing. Good bearings ensure a longer service life on basic that you maintenance them carefully. Per manual’s instruction, some points of decanter centrifuge need to be lubricated every shaft and some need to be lubricated after running some hours.
5. A standard equipment is designed for common conditions, but not for all. In some cases, the end user need to make the jobsite condition to suit the equipment, like to make some isolation for keeping the equipment warm or cool, sometimes, the end users even put the decanter centrifuge in a air conditioned room or container to get an ideal performance.

The required definition of a solid waste is not based on the type and/or physical of the material, but on the fact that the material is surely a waste.  RCRA §1004 (27) defines solid waste as:

Any type of waste, refuse, sludge from a wasted-water treatment plant, water         supply treatment plant, or air pollution control facility, and other discarded    material, including solid, liquid, semisolid, or contained gaseous material,    resulting from industrial, commercial, mining, and agricultural operations and      from community activities.

RCRA defines the solid waste as a material that is discarded by being abandoned, inherently waste-like, recycled, or a military munition identified as a solid waste.

ABANDONED

The term abandoned  means discard in a simple way.  Under §261.2(b), a material is abandoned if it is disposed of, fire, or incinerated.  In addition, a material that is stored prior to, or in lieu of in any one of these activities, is also considered to be abandoned. In addition to obvious examples of abandonment, such as land disposal/burial, EPA also includes activities such as incineration within the definition of the term (50     FR     627; January 4, 1985).

NHERENTLY WASTE-LIKE

Some materials are always considered solid wastes under §261.2(d), even if they are recycled in some manner (i.e., they are considered to be inherently waste-like). Because these materials may be dangerous to human health and the environment when they are recycled, they do not qualify for any exemption of recycle.  Examples of inherently waste-like materials are the dioxin-containing listed wastes F020, F022, F023, F026 and F028.  Dangerous waste meeting the F021 listing is also considered inherently waste-like unless it is used at the site of generation as an ingredient in a product.  Also, any secondary materials that are characteristic or listed dangerous wastes are considered to be breath-in waste-like when they are fed to a halogen acid furnace.  This provision was added to ensure that halogen acid furnaces burn some of the most toxic wastes generated in the US, adulated when burning any type of hazardous waste (56    FR     7141; February 21, 1991).

RECYCLING

A material is recycled if it is being used, been reused, or being reclaimed (§261. 1 (c) (7)).  These three terms have specific regulatory definitions.  A material is reclaimed if it is processed to recover a usable product or if it is regenerated (e.g., regeneration of spent solvents) (§261.1(c)(4)).

MILITARY MUNITIONS

On February 12, 1997, EPA finalized a rule that specified when unused and used military munitions are considered discarded and become solid wastes (62     FR      6622).  Military munitions that are not using become solid wastes when the munitions are removed from contain unit  for disposal or treatment prior to disposal; when the munitions are leaking or rot, so that they cannot be recycled or reused; or when declared a solid waste by an appointed military official.  New and/or unused munitions that are fixed, recycle, or reclaimed, are not considered solid wastes, nor are they counted as solid wastes while in storage in demilitarization accounts . It applies as solid waste when  munitions are finally removed from storage for the purposes of disposal do they become solid wastes.

drilling cuttings solidsfication unit

The Solidification Unit is a system conbination with screw conveyors and a Mature high shear mixers which has been already in the market for a long time. So it looks like new product but it’s not new product. The solidification unit and thermal desorption unit, as one of the most efficient and economic drilling waste disposal method, has been widely required by drilling waste management companies. solidification techniques are not only used for the treatment of wastes but also for other applications such as the treatment of contaminated sediments, industrial effluents, and for the rehabilitation of polluted sites. GN Solids Control new developed solidification unit has been shipped to domestic client.

Decanter Centrifuge is so named because it Decants, or removes, free liquid from separated solids. Decanter centrifuge work on the principle of exposing the process fluid to increased ” G-force”, thus accelerating the settling rate of solids in the fluid. A rotating bowl creates high G-forces and forms a liquid pool inside the bowl.

The free liquid and finer solids flow toward the larger end of the centrifuge and are removed through the effluent overflow weirs. The larger solids settle against the bowl wall, forming a layer. these solids are pushed by a screw conveyor across a dtrainage deck, or beach.Dewatering actually takes place on the beach,with the decanted solids discharged through a series of underflow ports. A gear box changes the relative speed of the screw conveyor to the bowl, Causing them to rotate at slightly different rates. this speed differential is required to convey and discharge solids. The bowl and conveyor are rotated at speeds between 1500 and 4000 rpm depending on bowl diameter.This rotation generate centrifugal force sufficient to settle solids along the inner surface of the bowl wall. A gearbox is used to rotate the conveyor and bowl at slightly different speed. this speed differential conveys and discharge solids from the centrifuge.

Bowl sizes in commom oilfield applications include diameters of 14 inch, 15 inch,18 inch, 24 inch.In unweighted mud applications feed mud capacity can range from 25-250 gpm, depending on unit capability and fluid requirements. solids tonnage rates range from 1.25 tons/hour to 8 tons/hour.in weighted mud applications,feed mud capacity rarely exceeds 25 gpm. Total liquid throughput maybe as high as 40 gpm,including dilution liquid. Dilution liquid is required to compensate for increasing viscosity,generally associated with increaing mud weight,in order to maintain satisfactory separation efficiency. The raw mud feed rate is substantially decreased as mud weight increases.

GN Solids Control is the first API certified Solids Control Equipment manufacturer in China. oilfield decanter centrifuge is one of our maini equipments. For more information about decanter centrifuge, Please feel free to contact with GN Solids Control.

A client inquired GN for a sump tank, with a high G shale shaker installed on a tank.They tend to adapt the shale shaker as high G dryer. They required the length and width of the tank is exactly the same with shaker length and width basket, meanwhile and they want the height of the tank to be at range of 1 m.

They also need two flanges by 2″ and 3″ size to be installed on width side close to the bottom the tank to be able to connect a Welden pump (air supply type) and suck collected oil for the tank that has been installed below the H-G Dryer into the active mud system.

For the shale shaker, they tend to choose API 40 & API140 shaker screen based on their detail condition.

GN suggest them with the latest design 4-panel high G shale shaker, whose shake screen is interchangeable with Brandt Cobra shaker.GN design the tank dimension of 2775mm×1652mm×900mm.Total height of the shale shaker is within 2.5m, shake shaker do not need to removed for transportation.40feet high cube container is ok for ocean shipment.

Water cleaning equipment base

Environmental protection has been more and more attache importance these years . Waste water cleaing has been grown stronger , so thant waste water cleaning equipment has been more and more popular .

Waste water cleaning equipment content

Waste water cleaing equipment could be different as per different conditions of waste water . I came across one clients need to separate solids 5% of 500 micron to 15 micron . If that , we could choose a small mud cleaner GNTJ60 with 1 qty of desander cone and 4 qty of desilter cone for total capacity within 60 cubic meters per hour . 2 Centrifugal pump SB4X3-12  11kw to feed the desander and desilter cone . A small tank 3.5m long X 2.3m wide X 1.3m high .

Water cleaning equipments difference

Waste water cleaning equipment is similar with drilling mud cleainng equipments , but there are some difference between them . Mostly it’s treating capacity regularly not same , and they need different equipment .  Sure it’s working principle for the equipments are same .
