Thermal Desorption Unit for oil tank bottom cleaning

Thermal desorption is an environmental remediation technology that utilizes heat to increase the volatility of oil such that they can be removed from the oil sludge or oil tank bottom. The thermal desorption unit is used for oil recovery and reduce hazardous waste for the environment. The recovered oil can be used for the operation of the TDU or be sold for money, the solids waste can be as waste injection, land fill or drain off in the sea, because after treated by TDU, the oil content in the solids waste is under 0.3%, which can be disposal directly. It is accepted by most of countries environmental protection laws. Not only for oil waste treatment, TDU can be also used for various materials, like soil, sludge, sand, filter cake, tank bottom, organic based hazardous waste and contaiminated soil. Just considering the total cost, some clients will not use TDU for low profit projects, we will recommend other equipments, like desander, desilter, shale shaker, decanter centrifuge, vertical cuttings dryer, etc.

The recovered oil is a mixture of oil and water, we will apply oil water separator to get pure oil. The oil water separator is a device designed to separate gross amounts of oil and suspended solids from the wastewater effluents of oil refineries, petrochemical plants, chemical plants, natural gas processing plants and other industrial oily water sources.

The power source of the TDU is coming from burning of oil, the oil consumption is max 80kg per hour for 2 burners. The recommend material is oil content less than 15%, water content less than 15%, the total fluids content less than 30%, and the max fluids content no more than 40%. If the fluids content is bigger than 50%, we can use pre-treatment equipments before TDU. For more information, pls contact GN solids control.

How to design VFD Control Panel for Decanter Centrifuge

The drilling mud decanter centrifuge driven by VFD will give many benefits to the clients. The adjustable bowl speed and differential speed allows the operators to set the right G force and solids pushing speed according to the drilling mud conditions.

To design the VFD Control Panel, the contractor needs the power supply specifications. Normally it is 460V/60HZ for USA standard or 380V/50HZ for Europe and China standard. Than the pulley size of the motor and bowl side will decide the bowl driving speed at different frequency. After confirming the bowl speed formula, the contractor needs the formula for calculation of the differential speed. For GN Decanter centrifuge, the Sun-Wheel gear box ration is 57:1. So the differential speed will be the bowl speed minus the gearbox input speed and divided by 57.

For the VFD Control panel, there is different explosion proof standard. In China, it is CN Explosion proof which is close to IEC Ex standard. In Europe, it is ATEX Explosion proof. And in North America, the explosion proof standard is UL for USA, and CSA for Canada.

GN Pressurized VFD Decanter Centrifuge control panel is specially design for Zone 1 or Zone 2 standard with ABB VFD and stainless steel cabinet. The PLC smart control allows the user to operate the drilling mud decanter centrifuge by HMI screen.

GN VFD decanter centrifuge has been exported to over 30 countries and regions, GN Solids Control VFD decanter centrifuge is available in different sizes including: GNLW223C-VFD (9inch) bowl, GNLW363C-VFD(14inch bowl), GNLW453C-VFD (18inch bowl), and the big bowl big volume centrifuge with 22inch bowl and model is GNLW553C-VFD.

GN 500 GPM Series Mud System for HDD or Other Trenchless Drilling

Hebei GN Solids Control Co., Ltd is actually leading manufacturer in solids control and mud recycling. Besides as the top one out of solids control field intended for oil and gas drilling, Hebei GN Solids Control Co., Limited is also the top one in mud cleaning system and recycling system for Bored Piling, Side to side Directional Drilling, Tunneling etc. Take GN 500 gpm mud system as an example, GN has 4 standard designs with different equipment for different forms of drilling activities.
GNMS-500D fiscal mud cleaning system, also referred to as the desander unit can be used to clean drilling slurry regarding bored piling. It is a two phase treatment plant using a desander mini cleaner attached with a mud tank which is split up into two compartments: shaker inner compartment and desander compartment. Usually no mud mixing system is needed. The slurry popping out from bore piles will likely be collected in a mud abyss from which a submersible slurry pump will deliver the slurry to smoothly and stably feed GN 2 period mud treating cleaner by using a buffer box. The slurry will flow across the little cleaner’s bottom deck predetermined with 25 mesh screen leading the liquids blended with fine solids to through the screen openings while rough solids to stay on the screen and move forward until going out. The liquids are going to be collected at shaker inner compartment and pumped to the desander cyclone for the second phase treatment with particles around 40 microns being segregated. There will be top deck screen to dry the liquids as being the dewatering screen. After that, the actual slurry is cleaner in addition to being able to be reused. We have now already delivered many value packs to many countries. Around ten sets are now operating in Myanmar bore piling site.

Decanter centrifuge for HDD

Decanter centrifuge is seldom used for plan directional drilling because of the high-cost and separation factor. Only if the fine solids gathered on the mud recycling system and the desilter cone cannot separate them out, then this recycled mud can not be employed for drilling unless the great solids (smaller than 12-15 microns) could be reduced. GN low speed/ middle acceleration decanter centrifuge GNLW452 centrifuge should be used by such circumstance.

GN has shipped several sets of 1000gpm mud recycling system with a couple of units of GNLW452 decanter centrifuges for CPP(China Oil Pipeline Bureau) for their traversing project. Totally 4 value packs of desander mud clean with 2 10inch desander cone and double veranda shale shaker GNZS705, 5 sets of desilter magnetic cleaner with 10pcs 4inch desilter cones with two times deck shale shaker, eight sets of GNLW452 decanter centrifuge with 18inch serving diameter, 1800rpm speed, 7 sets of centrifugal pushes to feed for the desander, desilter, 8 sets regarding feeding pump for the decanter centrifuges. 8 sets connected with 20ft container to install typically the equipments on it and with memory space.
This is not the first order through CPP, they start to purchase mud recycling system regarding HDD since 2010, and also until now they already purchased 30 sets of going mud cleaning system through GN solids control.
Typically the function of the decanter centrifuge in this system is not to different all the fine solids within 15 microns, the purpose should be to reduce the fine solids information in the recycled fluids therefore it can be re-used for the going. So the centrifuge capacity aren't required to equal with the solids control mud cleaner, it is not generally running, we will open it depending on the mud conditions.
Not only to get HDD mud recycling program, the same design could be utilized for tailings treatment of mining, essential oil drilling. Welcome to contact GN solids control for more info.

What is "IECEX/A-TEX" mark on GN Solids America’s solids control machines?

Oil rig drilling is world-wide operation and solids control machinery and system is manufacture t that it can be operate on any corner of the world, land and sea alike.  As been one of the most hazard working- area condition, the electronic parts of machinery often marked "IECEX/A-TEX".  This is the certificate marked as Hazardous Area Certifications.  The mainstream mark is IECEX which is international which every country accept the standard while ATEX is European standard but most countries are accept the standard as well. 

Explosive atmospheres can be caused by possible burning gases, mists, vapors or by combustible dusts, in combination with oxygen. With a certain concentration density all that is needed to cause an explosion is a source of fire cause by heat and spark.

ATEX or IECEX certified machinery will secure the operators and its machinery assets that under no matter in any working condition it will not cause an ignition so in conclusion it is safe, end of discussion.  The standard divided into different zones that ID potential hazardous atmosphere in the area.

ATEX based on the requirements of two European Directives:

1.  Directive 99/92/EC (also known as ‘ATEX 137’ or the ‘ATEX Workplace Directive’) is minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.

2.  Directive 94/9/EC (also known as ‘ATEX 95’ or ‘the ATEX Equipment Directive’) on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres.

What IECEX Scheme is an international Conformity Assessment Scheme covering Electrical Equipment for Explosive Atmospheres, as the internationally accepted means of demonstrating conformity with IEC Standards prepared by IEC TC31.

ATEX standard is about enabling to trade in European countries. Its purpose is to establish a level of safety which is to be regarded it is sufficient to ensure European authorities would accept the equipment certified.  

Difference compare with ATEX, the IECEX is about giving confidence that a product or service meets clearly defined transparent criteria. By providing its transparency with a high level of confidence, it is intended that it will eventually provide a worldwide recognized and acceptance certificate in which the whole world has confidence. The driving force is safety, with the trade benefits following from the confidence.

Shale shaker purpose

The shale shakers are mainly powered by the rotation motors to rotate and produce the periodic changed passivity force, drilling fluid that contain solid phase pass through the mesh screen, do the forcing movement on the mesh surface, and then the solid phase debris with various size will be filtered. The separation sizes and through put of the shale shakers is the most important factors of making use decision. The technology level of shale shakers mainly show at the treating capacity, the stability of filter debris, the life of operation and the flexibility of operation. The managing ability of shale shakers is related with the structure of shale shaker steel body, the movement arrangement, the vibration frequency, the vibration intensity, the working area of shale shakers and the degree of thickness. In order to make the shale shakers match with the drilling machineries, the maximum outputs of the drilling pumps and the quantity of drilling cuttings filtered must be considered.

Shale shaker is one of the main products of GN solids control .GN  sell a series of solids control equipment and drilling waste management equipment including vertical cuttings dryer , shale shaker , screw conveyor , shear pump , oilfield shale shaker , mud cleaner , desander and desilter , vacuum degasser , poor boy degasser , decanter centrifuge , mud tank , mud agitator , etc .

The classification of shale shaker

It depends on the movement arrangement; the shale shakers can be grouped into round screen shaker, the common elliptic screen shaker, linear screen shaker, equilibrium elliptic screen shaker. The common elliptic screen shaker: also can be called the disequilibrium elliptic screen shaker, there is a exciter devices fixed right above of the screen box , the screen boxes may tilt an angle, use the leverage of the gravity, avoids the sand having the tendency of back flowing. From this, the tilt of the screen boxes really improved the flowing performance of sand, but the disposed amount of the drilling fluid reduced, this is the main disadvantage of the common elliptic screen shaker. The linear shale shakers: Two main axises with eccentric blocks do synchronous reverse rotation to produce the liner vibration. Because the direction of the liner shale shaker is unchanged, which makes the debris difficult to fall through, and then the screen paste aspect appears, which makes the valid over flowing area of screen and throughput reduced. When the number of screens increases, the aspect of screen paste will be more serious. So when the linear shale shakers use the super fines screen, it could not meet the requirements of the using amount of drilling fluid.

GN Series Pumps Used for Solids Control and Waste Management

Besides the main equipments used for solids control and waste management systems and HDD, CBM, Piling drilling projects, like the shale shaker, desander, desilter, mud cleaner, decanter centrifuge and vertical cuttings dryer, GN also produce suitable and reliable auxiliary equipments including mud agitator, mud gun, jet mud mixer and various of pumps.

Below are some popular pumps and their applications for your information:

1. centrifugal pump GNSB Series, which is also called sand pump. It uses centrifugal force to suck the material and feed to the main equipments. In a complete system, it is widely used like the desander cones feeding pump, desilter cones feeding pump and also the mixing pump for the jet mud mixer. In trip tank for a large solids control system, centrifugal pump is also used.

In a mud recycling system for the HDD, CBM, TBM or Piling, in most cases, centrifugal pumps are used as desander or desilter cones feeding pump also, and also mixing pump for the jet mud mixers. Sometimes, per client special request, it could be replaced by a horizontal slurry pump when serving as desander or desilter feeing pump.

2. shearing pump, plays similar role as centrifugal pump, but in some special chemical transportations, it is feeding pump for jet mud mixer also and because of the different design, it could also cut the chemicals during transportation.

3. submersible slurry pump, it serves mainly 2 applications in GN series solids control system and waste management systems, the first one is centrifuge feeding pump for GNLW363 decanter centrifuges, GNLW452 decanter centrifuges and etc. The second one is the feeding pump for a mud recycling system for HDD, CBM, TBM and piling works. Unless the oil and gas drilling rig jobsite, where the drilling mud could flow directly to the shale shaker, in such mentioned projects, the mud for treating mostly comes from the mud pit. A submersible slurry pump can help to suck mud from the mud pit to the system.

4. screw pump or called mono pump. GN is not manufacturing this screw pump, but in order to match suitable screw pump for the centrifuges, GN cooperate with the German brand Netsch. Screw pumps are most suitable solution for feeding the decanter centrifuges.

May you need any of them, welcome to contact us freely.

Why The Drilling Waste Should Be Treated or Handled

Where is a well being drilled, where is the waste generated. The wastes generated by drilling vary from the drilling fluids used for drilling and the drilling site, but generally include drilling cuttings, waste water, spent drilling fluids, completion fluids and filtration wastes. Absolutely the wastes are contaminants to the surrounding ground and water if directly buried in the mud pit. With increasing public awareness of the damage caused by the wastes, the stricter environmental standards and regulations on drilling activities, the significance of the handling and treatment of has attracted the eyes of drilling contractors and increased in different degrees around the world.

The handling and treatment process depends largely on the local regulation of a country, while in a country where there is no environmental regulation on the drilling activities, the drilling contractor will fall back on minimum standards used in other countries or standards set at a corporate level. Generally, 4Rs can be used to describe the process of handling and treatment of the drilling wastes: Reduce&Reuse&Recycle&Recover. Reduce means reducing the wastes by some methods such as precise plan, smaller bole and selection of drilling fluids. It would be perfect if no waste generated when a well is drilled. Reuse means cleaning the waste to collect active drilling fluids by solids control equipment normally including shale shaker as 1^st phase, desander& desilter or mud cleaner as 2^nd and 3^rd phases, and decanter centrifuge as the final phase. Recycle means to further treat the drilling cuttings after Recycle after the recovery of  the drilling fluid for reuse. Recover means to make the drilling cuttings into a hydrocarbon by high temperature treatment. Though the recovered hydrocarbon can not be used as drilling fluids, it can be used for a fuel material.  

GN Desanding Unit for Construction

except solids control system for gas and oil drilling, GN solids control also designs and manufactures mud recycling system for other sorts of drilling, for example horizontal directional drilling, CBM, Tunneling, geothermal power drilling and piling. GN Desanding Plant is really a special mud making clear system for mining, piling, and horizontal directional drilling created by GN based on clients’ needs. This technique includes a working capacity of 120m3/h. This technique is made to consist of 2 stages of solids control and clarification procedure. For any compact structure, this technique combines a shale shaker along with a desander right into a desander mud cleaner whose model is GNZY753E-Y1S. First level separation is as simple as a shale shaker, and 2nd level is as simple as a desander.

The dwelling of GN Desanding Plant is proven in Fig 1 to Fig3, including mud treating tank, GNZY753E-Y1S Desander mud cleaner, GNSB6×5A-12J Centrifugal Pump, light, electric control and ladder, handrail, pathway and pipeline. This drilling mud system has compact structure and rational layout, and it’s simple for installation & dissembles.

The underside deck from the double deck shale shaker with 25 mesh screens is perfect for first stage cleansing treatment. When mud transferred towards the bottom deck for process, the solids whose dimensions are bigger compared to holes on screens is going to be released out, while fluids will mix the screens then fall into the mud tank. Then, the mud is going to be shipped towards the cyclones with a sand pump for more solids removal. Solids from the desander cyclones will fall on top deck with 40 mesh screen after which be released out. The liquid is going to be released in to the arranging tank through overflow pipes. Floating ball will close the pipeline once the mud reaches enough high, then the drilling mud after processed will flow out of the discharge port.

Dredging Slurry Rapid Dewatering System for Water Solution

Many facilities are focusing on processing the contaminated water to make the water clean and also the removed solids safe for disposal. When mentioning the contaminated water, the polluted river and lake water along with the industrial water will always be concerned. How to find a good means to process water cost effectively can be the most critical problem the operator considering.

Here the dewatering system could be a perfect option. This rapid dewatering product is including several modules which individually functions various processing job. The idea of the operation is to discharge as find solids in the contaminated water as you possibly can, that will need various kinds of separation equipment.

For the beginning part to discharge the coarse debris and sand, the solids control equipment could be a great solution. It might need a coarse screen shaker which is often used to discharge, dry and stockpile bulky debris in the dredge slurry, for example rocks, shells, and cans. The underflow flowing through the screen could be pumped towards the desander unit for more treatment. The de-sanding unit uses the hydrocyclones to split up the sand by weight and size. Underneath the cyclones, the linear motion shale shaker is adjusted to handle coarse sand at anywhere and kind. The dried and stockpiles sand could be used again and moved. GN Solids Control is really a reliable supplier for that coarse shaker and de-sanding unit.

For that ultra fine solids still contented within the dredge slurry, it needs to be flocculated using the correct dose of polymer. Here require a feed tank to help keep a reserve of slurry that's continuously mixed by agitators. The slurry could be pumped towards the polymer system.

The rapid dewatering system could accomplish our prime speed dewatering, scalable and eco sustainable project for dredging slurry dewatering processing.

3 in 1 combo mud cleaner

Reference "3 in 1" combo in solids control machinery is called mud cleaner.  The combo is group of swirler in 10 inches called desander and 4 inches called deselter. Both desander s and desilters constructed together and installed on top of the shale shaker. Such set up combine the phase two and three of drill mud filtering and cleaning 

Drilling mud cleaner is composed of a group of swirler, a set of detail screen shale shaker and shunt manifold. The top is a group of swirler, the underpart is the detail shale shaker. It is the second level separation equipment in the drilling mud solids control system.  This machinery set-up is ideal for operation-sensitive and limited space available environment. 

 When the mud cleaner handles the weighted drilling fluid, the drilling fluid which is already handled enters into the drilling fluid system from the top of the desander swirlers. The drill cuttings, barite and a mud phase discharge from the bottom apex and go to the high- detail meshed shaker screen. The granularity of barite is overall 2~74um, it will pass-through to the drilling fluid system with the liquid phase and the drill-cuttings which are smaller than the screen mesh, the drill cuttings which are larger than the screen mesh will left remain on the screen surface. In this way,  3 in 1 mud cleaner cleans the drilling fluid, stabilizes the performance of drilling fluid and recover and recycle-use  the barite and the drilling fluid.

 Compared with the desander and desilter set up separately,  3 in 1 mud cleaner has the advantages of large handling capacity, fast processing speed, small structure, easy to operate and easy to maintain. Mud cleaner synthesize the advantages of shale shaker and swirlers called hydrocyclones, it can eliminate the harmful solid phase quickly, and improve the performance of drilling fluid, and satisfy the demand of the drilling rigs that req

Each one of these certificates signifies that GN Solids Control is a company worth trust and reliance.

GN manufactures and supplies solids control system for gas and oil drilling in a variety of depth. Within the whole group of solids control system for gas and oil drilling, generally you will see four stage solids control equipment including shale shaker (first stage), desander (second stage), desilter (third stage), decanter centrifuge (fourth stage). Alternatively, the desander and desilter could be changed through the mud cleaner using the mixture of desander cyclones and desilter cyclone. And when the drilling is simply too deep, two teams of decanter centrifuge is going to be used. The main one is medium speed, and yet another is high-speed decanter centrifuge. Beside solids control system, GN also supplies mud system for a number of types of drilling, and drilling waste management system for drilling cuttings.

Besides top quality product, GN also supplies considerate service:

2014 GN Projects for Asia Market: Mud Recycling System for HDD and Tunneling

As the top manufacturer in China of solids control equipment and system for gas and oil drilling, besides solids control system, GN solids control also focused on mud recycling system for horizontal directional drilling, and tunneling. Not the same as solids control system, mud recycling system doesn't requires to split up the ultra-fine solids out, so normally you will see 2 or 3 stage equipment: shale shaker, desander, desilter (sometimes, we make use of a double deck underflow shaker using the desander or desilter on top in order to save cost and space sometimes the mud cleaner is going to be adopted in order to save cost and space using the mixture of desander and desilter)

This season, GN shipped one set mud system for any Hong Kong customer, this technique incorporated two teams of GN 4 panel shale shaker some large capacity mud cleaner one group of poor boy degasser, some vacuum degasser, and some conveyor, as well as mud tanks.

GN also shipped 500gpm mud system for trenchless drilling project in Thailand two group of mud recycling system to India for horizontal directional drilling with Vermeer rigs. The first is 500 GPM with shale shaker and desilter the first is 350gpm with shale shaker and desilter. GN could supply various treating capacity mud recycling systems for horizontal directional drilling drilling.

More to the point, GN designed and manufactured an entire group of TBM mud system with dewatering unit for any Singapore customer. This project needs a large treating capacity; therefore the greatest decanter centrifuge sitting 80 cubic meters each hour is adopted. And also the dewatering unit is required to make small solids aggregated into large ones after which to become processed through the decanter. GN is experienced in solids control and mud system.
