GN Modular Waste Cuttings Drying Unit

The reason that GN solids control made this kind of design is to provide more customized solution and save the customers with great funds. According to the feedback from the customers who are always working on the oilfield, GN firstly launched the skid mounted drilling waste cuttings management system with the key equipment vertical cuttings dryer and waste decanter centrifuge mounted on the same skid. This complete skid could be moved by only 1 trailer, which is the customers’ preference. While some other customers came to GN and ask whether they could get single equipment and connecting with their existing waste cuttings drying equipment. Or due to the limited space on site, they cannot put a 40 ft skid on the site, they are seeking some units could be located more freely. The modular waste cuttings units are exactly what they are looking for.
GN’s modular waste cuttings drying unit series includes telescopic skid vertical cuttings dryer and decanter centrifuge, High G force drying shaker with under located catching tank, the intermediary tank specially for effluence storage, waste cuttings transferring unit and the waste collection container unit.
According to the base of the drilling mud, the user could choose to use the cutting dryer or high G drying shaker as the critical equipment to make a complete waste cuttings drying system. Comparing with the 40ft size design, the modular unit has the advantages of freely located onsite and the connecting is more customized. The user also could choose several units of the complete line according to their budget.
GN’s modular waste cuttings drying units have been used onsite and the feedback is returned good. Keeping providing the customer with good solution and bringing benefit for the customer is always GN’s purpose.

Still feel difficult to find a good solution to dispose the drilling waste cuttings? GN solids control now has developed the complete treating system for to drying the drilling cuttings and recover the drilling liquid stick on the cuttings maximally.

As per the market feedback and customer’s requirements, GN has independently designed 2 series waste cuttings management system with the Model No. of GNCM-40A and GNCM-40B.

The Configuration of GN Drilling Waste Cuttings Drying System

First Stage separation: GN’s drilling waste cuttings drying system mainly includes 2 modules, in which the first module is the vertical cuttings dryer system. The cuttings dryer model of GNCD930 is designed with fixed speed and variable speed. The cuttings with size larger than 250 microns could be removed by the screen located inside the dryer bowl. By using the material of stainless steel, the screen would have better features of anti-corrosion. With the air knife and flushing system on the cover of the dryer, the dryer could consistently for longer time without blocking on the screen. The super high speed of 1200RPM could produce the G-force of 750. If application for the oil based drilling cuttings, the oil content could be reduced down to 3-5 percent.

Second Stage Separation: The fluid going through the screen opening of the cutting dryer would be fed into the high speed decanter centrifuge series of GNLW363CG with working RPM of 3200. Here, the solids down to 2 microns could be separated out.

In this system, both the cuttings dryer and decanter centrifuge have fixed speed and variable speed models for option which could meet the customer’s request for different drilling mud conditions. GN’s VFD control panel is PLC smart design with visual and touchable screen for easier operation.

For this system, we also provide the feeding pump system. And as per customer’s option, GN could also provide the cuttings delivery system screw conveyor for feeding and discharge.

The customer could choose to locate the decanter centrifuge on the telescopic frame or catching tank. That is also the difference between the model of GNCM40-A and GNCM-40B. The GNCM-40A is to put the centrifuge on the telescopic frame with the height adjustable, the discharged clean liquid would pipeline manifold guiding to other catching tank. While the GNCM-40B is self with the catching tank beneath the decanter centrifuge, the liquid could be stored in the catching tank and wait for pumped to reuse.

GN drilling waste cuttings drying system is an excellent solution to make the cuttings dry so as suitable for transportation. And it maximally recovers the drilling liquid to reduce the drilling cost.

GN just finished an order for a customer from Russia who required the drilling cuttings dewatering decanter centrifuge and some cuttings transferring equipment.

GN High Speed Centrifuge

The decanter centrifuge is common seen and widely used equipment in the drilling industry to remove the solids from the drilling fluids. While the centrifuge unit involved in this order GN’s most popular model GNLW 363 series. The bowl diameter of the centrifuge is 14 inch. For this model, GN could provide 2 speeds of 2670 RPM and 3200 RPM by changing the belt pulley. For different speed, the unit could be used for different processing. For barite recovery, the low speed 2670 would be suggested. While for ultra find solids separation or dewatering project, a high speed would be preferred.
GN provides 2 options to customer for changing the speed of the decanter centrifuge. As mentioned above, one way is to adjust the speed by changing the belt pulley, once the belt pulley fixed, the speed are fixed. Another better solution is to use a VFD model, GN’s design of PLC variable frequency drive decanter centrifuge GNLW363- VFD could realize the typical working speed various from 0 to 3200RPM which could meet various processing demand.

GN Screw Conveyor

Attached with the decant centrifuge, the customer also required the transferring equipment. What GN provided for this order is the Screw conveyor which is also called auger. The auger is widely used transferring equipment in the job site for drilling and some other industry projects. GN’s auger is classified as 12 inch, 14 inch and 16 inch for screwy diameter. According to customer actual working condition, GN could design the auger with fully power could meet the customer requirement for transferring the cuttings with certain slant degree. The motor installation type has horizontal and vertical type for option.
GN can also provide the vertical cuttings dryer which is also critical equipment in the drilling waste cuttings management projects. For more information, welcome contact with GN Solids Control.

Verti G cuttings dryer is specially used in drilling fluids solids control system to recover the waste cuttings out from the primary shale shaker and mud cleaner. At present, the company CSI is the world accepted most famous manufacturer for the Verti G cuttings dryer unit. No matter on quality and production series, CSI is the No. 1.

GN verti G Cuttings Dryer with Flushing and Blowing System

VVerti G Cuttings Dryer Unit

GN Solids Control has been dedicated to design and manufacture the Verti G cuttings dryer in the past three years, and now GN 2nd generation cuttings dryer have been tested successfully and already applied on site. GN’s verti G unit is workable for both the water based drilling mud and oil based mud which makes GN Solids Control occupy the first seed in China solids control market. To ensure the smooth performance of the verti G dryer, GN equipped on the unit with flushing and blowing system.

GN Verti G dryer flushing system

The flushing system on GN second generation verti G cuttings dryer is consisting of a screw pump and relative hoses. Usually the material getting into the Cuttings dryer would be high viscosity and dry. With the rotating of the dryer bowl, the fine solids and liquid would be sprayed on to the inner surrounded wall of the bowl and stick on it. To clean the inside of the cuttings dryer, the screw pump would feed clean water into the bowl. Under the high pressure of the flushing water, the fine solids and dirty liquid would be flushed down from the wall and get out from the dryer vessel.

GN Verti G Air Knife System

One of GN first generation Verti G cuttings dryer defects is that the discharged solids out from dryer unit is not dry enough for easy transportation. The air knife design could solve the problem of the block on the rotating screen opening. GN’s vertical cuttings dryer has 3 types screen for option, the opening is 250 microns, 350 microns and 500 microns. Under high pressure of the blowing air, the blocked opening of the screen would open and the solids would be blow to much dryer. This greatly enhances the working efficiency and makes the transportation of the discharged solid very easy.
Besides the verti G dryer, there would be another important equipment called decanter centrifuge which would remove the much fine solid particles in the drilling mud.
