Sludge and solids vacuum pump for waste management

Reference to GN Solids Control scope of supplying pumps, clients may contact GN and would like to get more information of GN Vacuum Sludge Pump: Complete technical catalog and performance capabilities, etc…

GN Solids Control has 3 models solids and sludge vacuum transfer pump: GNSP-40B, GNSP-20B, and GNSP-10B. GNSP-40B is a large model with mounting skid. GNSP-20B and GNSP-10B are portable models with tires for easy movement.

2020.10.16 Sludge Vacuum Pump

GN vacuum pump is specially designed for long distance solids and sludge transfer. In order to ensure the pump can meet clients working situation and can solve their issues, before order, GN Solids Control sales engineers will send a questions list about vacuum pump. Clients are requested to answer as more as they can to let GN know more about their jobsite and their demands. Then GN engineer will see if the pump can suit the applications.

The pump is 100% driven by air. Clients also need to pay attention on the air supply, and compare which pump model they can have qualified air supplier. Clients can feed air from rig or from other air supplier, or by separate an air compressor.

Actually, GN Solids Control usually ask two typical questions to make sure the vacuum pump is suitable to use:
1.  Where does the material originally come from? If there are big stones or aggregates, the pump will not work.
2.  What’s the height between the suction port and material? Should be within 8 meters in order to work, otherwise need to lower the pump.  But the transfer length can up to 500m or 1000m.

Except for the vacuum pump for solids and sludge transfer, GN Solids Control makes various sizes of screw conveyors for drilling cuttings transfer. And GN Solids Control make full line separation equipment for drilling waste management, oil sludge treatment and for waste slurry treatment. GN major separation equipment includes shale shaker, decanter centrifuge, disc centrifuge, vertical cuttings dryer, high G drying shale shaker.

Drilling waste cuttings dryer for waste management

There are many clients inquire cuttings dryer to treat drilling waste and drilling cuttings from oil and gas drilling mud recycling system. GN Solids Control makes 2 types of cuttings dryer separator for drilling cuttings treatment.

A type of cuttings dryer is vertical cuttings dryer (short as VCD). It is also called as vortex centrifuge, or vertical centrifuge. The GN Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900RPM with G force to 420G.

Vertical cuttings drying system

The vertical cuttings dryer is mainly designed to treat oil based mud and oil based cuttings. After vertical cuttings dryer, the oil on the cuttings can be reduced to 3% ~ 5%.

Recently, some clients inquires GN Solids Control to ask for vertical cuttings dryer to treat the solids from decanter centrifuge. In fact, vertical cuttings dryer is not recommended to treat the solids discharge from centrifuge separators. As all centrifuges are for fine solids separation. The solids enter into centrifuge much with less 15% solids content. And the max. Particle size should be smaller than 2mm. While the screen basket of vertical cuttings dryer screen opening is 0.5mm or 0.35mm.There are fewer solids can be removed from centrifuge discharged solids.

High G dryer shaker is also called as cuttings dryer. GN High G Force Drying shaker is design for primary solids control and drying the cuttings from the primary solids control equipments, recover silts and ultra-fine sands, provide solids in a consistently stackable and conveyable form and requires no expensive chemicals or polymers. GN high G drying Shaker with Adjustable G force Up to 8.0 G. It can be used for both OBM and WBM cuttings. While used for OBM treatment, the oil on the cuttings (OOC) can be be lower as vertical cuttings dryer. But its cost is much lower than vertical cuttings dryer.

GN Solids Control can make high G drying shaker c/w a underflow catch tank.

Solids and sludge vacuum pump for crude oil tank cleaning

Solids and sludge vacuum pump is one of the major transfer equipment designed and made by GN Solids Control. It is a 100% air driving pump for sludge and solids transfer, especially for long distance transfer in various fields and industries, like to transfer rocks for construction companies, transfer powder for chemical companies, suction oil sludge from waste pit and transfer to oil sludge treatment equipment, transfer contaminated soil for soil washing system, suck the oily slurry from crude oil tank after tank cleaning works, etc…

GN Solids Control has 3 sizes vacuum pump, GNSP-10B and GNSP-20B is a portable size vacuum pump with tires for easy movement. The smallest size vacuum pump GNSP-10B can also be used as a industry vacuum cleaner after changing the suction pipes and suction head, and upgrade the control panel for both auto-control and manual control.

2020.10.16 Sludge Vacuum Pump

GN Solids Control solids and sludge vacuum pump is max. 8m vertical lifting height for suction as the limitation of air supplier. But the discharge distance can up to 500m.

While use for big size crude oil tanks, there are many crude oil tanks are very big size, the tank height is over 20m and over 30m. It is over the vauum pump suction height. What our other clients do is to put the vacuum pump inside the tank, they find a place inside the tank and fix the pump inside crude oil tank. In this case, they can reduce the suction height to not more than 8m.

Another way some clients may do is to insert the suction hose via the holes on the tank wall rather than from tank top to make the suction height less than 8m.

Besides solids and sludge vacuum pump, GN Solids Control makes other transfer equipment, like centrifugal pump, submersible slurry pump, screw pump, cuttings transfer pump, screw conveyor. Welcome contact GN Solids Control to inquire any transfer pump and separation equipment.

 

Drilling mud solids control screw conveyor for cuttings transfer

14 inch decanter centrifuge is widely used in oil and non-oil drilling field for drilling mud treatment. It is the most popular size for drilling mud treatment. There are fixed speed control, VFD control and FHD control for the 14 inch decanter centrifuge.

There are high speed and middle speed 14 inch decanter centrifuge. Clients can use VFD control or FHD control to change the centrifuge speed. For the fixed speed decanter centrifuge, clients can use different sizes pulley and belt to change speed. The middle speed centrifuge generates low G force for high gravity separation, like barite recovery. The high speed decanter centrifuge generates high G force for low gravity separation, for fine solids separation to reduce the mud weight.
