GN new completed oil sludge treatment system will be preceded for water test soon. Now the complete system is ready and staying is GN assembly workshop. GN oil sludge treatment system can be used in recovering the oil from various kinds of waste oil sludge coming from oil base drilling cutting, oil storage tank remaining sludge, refinery waste etc.

The ordered oil sludge treatment system is GN 2 cubic meters per hour model. Client is going to use this system as a demo to verify it is workable in recovering the oil from oil sludge. Actually, the excellent performance of GN oil sludge treatment system has been proved onsite. In this system, client plan to bring their SMO (shear, mixing and oxidation) unit to connect with GN oil sludge system for better demulsification performance.

GN Oil Sludge Treatment System is consisting of below modules.
1. Premixing Tank Module – the oil sludge is firstly transferred to the premixing tank by the vacuum pump. Here in the tank, water and chemicals will be added into the tank, with heating line around the tank, the sludge will be washed, much flowable.

2. Classify System – the washed sludge will then be pumped into a V-shape bottom tank for solids sedimentation and liquid classification. The top layer oil will be flow into 3-phase disc centrifuge for water, oil and solids separation. And bottom solids will be mixed; here the chemicals can also be added.

3. Solids Control module – in GN oil sludge treatment system, the solids control module is consisting of coarse shale shaker and decanter centrifuge to remove as much as possible solids from the sludge. To get as less as possible oil content on solids, the solids discharged from the decanter centrifuge can be washed again and then treated by the second unit decanter centrifuge. Liquid discharged from decanter will pumped to the second unit disc centrifuge for water and oil separation.

4. For back up, GN made the 3-phase separation skid module with inclined plate clarifier and oil water separator. To maximally reduce the oil content in water, GN made the micro bubble oil water separator in the system to make the water as clean as possible.

This month, there are some decanter centrifuges in GN factory will be assembled completely and then shipped to Russia for a waste water treatment project there. The ordered is GN 14 inch drum diameter unit with model GNLW363C-VFD.

GN Decanter Centrifuge Features

1. Top class material used for rotation part – GN 14 inch decanter centrifuge drum is using duplex stainless steel 2304 that is much better than SS316L. The centrifugal casting technology ensures the material distribution evenly so as to guarantee the excellent dynamic balance.

2. Protective design of wearing part- at all the decanter centrifuge wearing part like the screw propeller, inlet slurry distribution port and solids discharge port, GN protects all these parts with tungsten carbide alloy material to ensure a long working time. Inside the collection box and around the solids discharge port, GN installed scrapers to prevent the solids building up so as to protect the drum.
3. Humanized electric control panel – GN is able to equip the 14 inch decanter centrifuge with VFD control panel to run the drum with speed of 0-32mm rpm and the feeding pump with different flow rate. Operator only need to input the desired speed on the HMI touch screen, the worked by PLC, the centrifuge will run per the instruction.

With many years research and development, GN decanter centrifuge is able to be used in many industries like mud recycling, dewatering and waste water treatment. Last month, GN shipped out 2 big bowl decanter centrifuges to Australia for coal slurry dewatering. The units sent are with 30 inch bowl diameter which is the largest model GN can make at this time.

GN has 9 inch, 14 inch, 18 inch, 22 inch and 30 inch decanter centrifuge, by changing the centrifuge drum length and cone angle, these models could be applied in different industries. For more information, welcome contact GN.

Recently, GN finished the fabrication of almost 60 unit mud agitators and several unit vacuum pumps for a domestic client.

GN mud agitator is flanged connection type with compact structure. It is cost competitive and mostly used in the mud recycling system for mud mixing. In the mud system, mud agitator is installed in mud tank with stirring function to prevent the solid particles settlement down to the tank bottom. Another function is mixing to accelerate the dissolution of the mud materials. The mud agitator is mainly consisting of motor, gearbox, stirring shaft and impeller.

GN complete solids control system is provided with mud agitator, according to the tank depth, GN engineers know how long to design the agitator shaft and single impeller or double impeller needed. To prevent the disturbance of the stirring shaft when agitator is working, GN designs the stabilizer at tank bottom to fix the shaft.

When providing the single mud agitator unit to client, GN always will ask client to provide the inner dimension of the tank and the mud density, so that to propose the mud agitator with right shaft and power. GN is also to provide the mud agitator with motor starter.

GN vacuum pump is especially used for high solid content sludge transferring like drilling cutting from mud system to waste management system. It is fully pneumatic driven type pump that can be used in hazardous area with flammable gas. The vacuum pump is easy for maintenance as there is no any movable part inside the pump cavity. GN has vacuum pump with flow rate of 40, 20 and 10 cubic meter per hour for client to select. For easy and continuous operation, GN vacuum pump can work under automatically mode.

Recently, GN finished the fabrication of one set oil based drilling cuttings treatment system for CNPC project. Before, CNPC has ever purchased several units drilling cuttings treatment system from GN Solids Control.

The drilling cuttings treatment system is used to treat the drilling cuttings discharged from primary solids control equipment like shale shaker, mud cleaner and barite recovery decanter centrifuge. For environment protection and cost saving consideration, the drilling operators is using the cuttings treatment system to recover more drilling fluids from cuttings, in the meanwhile, less waste will be discharged into the nature. To increase the working efficiency, GN released the vacuum pump unit that performs well to transfer cuttings sludge to treatment system.

This oil based cuttings treatment system is a compact design with all relevant equipment mounted on one skid for easy position on drill site. The equipment lists as below:
1.Cuttings Dryer unit – this is the main equipment used to remove the large size cuttings and recover oil base drilling fluids. After treated by this unit, the OOC will be going down to less 5%. It is the most important equipment in this cuttings treatment system.
2. High Speed Decanter Centrifuge – the decanter centrifuge is used to polish the effluence liquid coming from the dryer unit by remove the fine solid particles. With a speed up to 3200rpm, the centrifuge will remove the solids bigger than 5 microns to make the drilling fluids more acceptable for reusing.
3. The skid of the system is designed to with a buffer tank that is divided into 2 compartments. First compartment is used for collecting the drilling fluid from the dryer unit, and the second compartment is to store the polished drilling fluids after treated by centrifuge. GN is using the Netzsch screw pump to transfer the fluids from first tank compartment to the centrifuge unit.

GN has rich experience in designing and manufacturing the drilling cutting treatment system and solids control system. Besides this skid mounted system, GN is also able to provide the modularized cutting treatment equipment.

Last week, GN shipped out one set high standard solids control system to Australia for a client from oil gas industry. Though the Australia standard is considered to be the strictest one in industry, GN was confident that the solids control system could be fabricated as per the standard and achieve client requirement.

Actually, GN ever shipped one sethelicopter lifting mud tank system to Australia client last year. That system was also high standard request on weight and tank design.

Below few request from Client to show Australia high standard

1. All electrical material needs to be Australia standard like the wire cable color which is considered to consistence concern when client’s engineer does the cable wiring job. This will not confuse the client so as to make the job easy. In oil gas industry, all electrical material like motors, control panels, even cable glands need to be explosion proof. For Australia, client request it should be IECEX standard, and GN is able to provide that.
2. In designing the tank system, client also provided many suggestions and notices to GN engineer to ensure the design is comply with the safety standard. These comments almost covered all aspects of the tank design from walkway, handrail, lifting pad, valves and even the distance between adjacent components. All these designs have specified request and need to be approved.
3. The tank top surface is fixed with high strength glass fiber reinforced plastics for long time working time and better resistance to impaction and UV. They also have very high standard in welding and painting.

The client is using this solids control system for a work over rig drilling project. The system is consisting of 2 tanks. The first tank would be used to fix 2 unit shale shakers for drilling mud cleaning, and second tank is used for adding mud chemicals as equipped with mixing pump and mud hopper. Both tanks have mud agitators and mud guns for mud mixing. For more information, welcome call to GN.

This month, GN arranged the shipment of two sets large bowl decanter centrifuge to Australia for coal mining slurry dewatering process.
The model of the large bowl decanter centrifuge is GNLW764 that is the largest centrifuge GN can make at this time. For the coal slurry dewatering project, always a large flow capacity is required. That is why the client selected GN largest decanter centrifuge.

Features of GN Large Bowl Decanter Centrifuge GNLW764A

1. The rotating bowl is made from duplex stainless steel 2304 with centrifugal casting processing for better balance performance.
2. Screw conveyor is also rom stainless steel and the blade is protected with tungsten carbide for long working life.

3. To protect the motor of the large bowl decanter centrifuge. GN equips the VFD control panel for the operation of the centrifuge. So that the motor can be started to run at a low speed to prevent the over high electric current to burn the motor. In the meanwhile, a VFD control panel will let the operator to run the decanter centrifuge with different speed for various process purposes.
4. The lubrication system is using oil pump to feed lubricants to both of the bearing seats. The plate type heating exchanging system can effectively cool down the lubrication oil so that to get a better cooling performance and the temperature sensor installed on the bearing seat will send signal to the PLC to trip off the centrifuge in case of over high temperature.

GN decanter centrifuge is mostly used in drilling mud solids control. However, now is applied in more and more other industries like mining slurry dewatering, waste water treatment and oily sludge treatment. For more information on GN big bowl decanter centrifuge, please contact us freely.

Last week, GN finished the manufacturing of several units poorboy degassers and shale shakers that ordered by an Egypt client. Now the order has been packed well and waiting for delivery.
Manufactured per API and ISO standard, GN pooboy degasser could be used in underbalanced condition drilling to prevent a dramatic pressure surges. For safety consideration, the poorboy degasser is seen as indispensable equipment on oil gas drilling site, especially for deep drilling rig. The poorboy degasser is also named as mud gas separator.

The poor boy degasser is always installed beside the mud system. In normal condition, the drilling mud coming out of the well will flow directly to the shale shaker unit for cuttings removing. In case gas layer was intruded by drilling tools, a blowout might happen. This is the time the poor boy degasser will be applied to relieve the high pressure of the gas- invade drilling fluids and separate the gas that might be flammable or hazardous.

GN’s mud gas separator has a simple structure with fluid inlet at upper part of the vessel. Inside the vessel, several baffle plates are welded on the inner wall of the vessel. The drilling fluids coming from the inlet will impact on the baffle plates so as to release the gas in the fluids.

Gas accumulates and then is vented out from outlet on top of the vessel. The treated mud will fall down and accumulate at the lower part of the vessel, and then discharged out to the shale shaker unit. At bottom of the vessel, there is a drain valve for cleaning of the poorboy degasser.

GN shale shaker has below features to provide excellent performance to client
1. Simple structure with strong vibration deck for easy operation
2. Composite frame screen for long working time and convenient replacement
3. Patented embedded sealing technology to prevent fluids leakage
4. Stainless steel screen support frame for better anti-corrosion performance
