GN Solids Vacuum Pumps for drilling waste cleaning to Africa

BY gnadmin 29 December 2022 Uncategorized

Recently GNSP-40B and GNSP-10B sludge vacuum pumps are ready for shipment for drilling waste cleaning to Africa. The application of vacuum pump used at drilling rig site including: drilling hazardous waste cleaning, waste pit cleaning, mud tank cleaning, drilling rig platform cleaning, drilling cuttings transfer, etc.

When the vacuum pump is used as drilling cuttings transfer, it can be used as screw conveyor, which will collect the drilling cuttings from primary solids control equipments, such as shale shaker, desander, desilter, decanter centrifuge, etc. The usage of vacuum pump and screw conveyor is according to space limitation, vacuum pump needs less space for installation, the max suction distance is 50m, the max discharge distance is up to 1000m, it is 100% air operation pump without electricity power supply, just it needs air compressor for air supply. The screw conveyor needs large area for installation, and the transfer distance is very limited, and the power consumption is also high. In actual situation, the user can use both vacuum pump and screw conveyor together, the drilling waste is collected in a collection hopper by vacuum pump and transferred by screw conveyor to drilling cuttings treatment system vertical cuttings dryer and decanter centrifuge for drilling cuttings treatment and cleaning.

When the vacuum pump is used for drilling waste and waste pit cleaning, there are automatic mode and manual mode for option, and connect suction pipe, discharge pipe and air hose with air compressor, if automatic mode is selected, set the suction and discharge time after running the vacuum pump for several loops. The maximum solids size for GNSP40B vacuum pump is up to 75mm, waste solids content is up to 80%.We also provide different type suction pipe and discharge pipe to transfer different waste material with different length, each section length is 10m with joint.

Sludge Vacuum Pump and Decanting Centrifuge for Environmental Solutions

Recently one unit of sludge vacuum pump and decanter centrifuge are ready for shipment for environmental solution.

The mini vacuum pump model number is GNSP-10B, the max capacity for water is 10m3/h, for oil sludge, industry waste, drilling waste transfer, the flow rate will be different according to material conditions. The inlet and outlet size is 3 inch (89mm), vacuum degree is 85Kpa/25 inch Mercury column, the max suction horizontal distance is 50m, max discharge horizontal distance is 500m, the max suction depth (vertically) is 3 ~5m according to density and viscosity, the max discharge depth vertically is 5~ 10m, the max solids content is up to 80%, it can be used to transfer high solids content material, and mx allowance solids size is 50mm. The vacuum pump is 100% air operated, required pressure is 550 Kpa ~ 690 Kpa(80~100 PSI), air demand is 4.3m3/min (150CFM). Working principal of vacuum pump for suction process is that the compressed air enters into the vacuum generator, which generates negative pressure in the pump body and suck the materials from the suction port. The discharge valve is closed. The suction time and discharged is set by the user according to their requirement. they can select automatically operation method or manually operation method as requirement.

The discharge process of the sludge vacuum pump is that closed the vacuum generator valve, the air flow directly enter into the pump body, the discharge valve is opening automatically, and the positive pressure will push the material along with the air flow out of the pump body, at this moment, the suction valve is closed.
The decanter centrifuge can be used for solids liquid separation for industry waste water treatment, dewatering centrifuge, waste separation, oil sludge treatment, etc. applications. If you need a decanter centrifuge, pls contact with GN sales engineer to select a model.

Mini Sludge Vacuum Pump for Oil Spill Recovery

BY gnadmin 9 June 2022 Uncategorized

GN produced mini sludge vacuum pump is used for oil spill recovery. The spilled oil mixed with earth, solids will be collected by mini sludge vacuum pump and transfer to oil sludge treatment unit for oil recovery and solids safely discharge. To get the oil recovery, firstly we need to dilute the waste sludge ,mixed with chemicals and well agitated, then the oil sludge will be treated by 3 phase decanter centrifuge to separate oil, water and solids; if the client need better quality recovered oil, we can use 2 phase decanter centrifuge to separate solids and liquid, then use 3 phase disc centrifuge to separate oil, water and solids.

Depends on transfer capacity, we have GNSP-40B, GNSP-20B, GNSP-10B,GNSP-05B with 40m3/h,20m3/h, 10m3/h,5m3/h for option. The GNSP-05B sludge vacuum pump can be used as an ideal solution for the cleaning of residual waste inside the cabin and the transportation of loose materials. The mini sludge vacuum pump can be used to transport and remove liquids with high solids content, oil sludge with high viscosity and clean bulk solid materials. And the pump is 100% air operated, without needing electric power supply.
Features of GN sludge vacuum pump:

Suitable for hazardous area application, no need electric power, need air supply.
Suction distance( horizontal) up to 50m, discharge distance (horizontal) up to 500 ~ 1000m
Allowed solids size maximum is up to 50mm to 75mm, the sludge solids content up to 80%
Automatically and continuously working is for option to save labor cost.
Compact design, easy to move and can be used if space is limited
Without rotating parts, with less wear parts for longer working life and less maintenance cost

As a manufacturer of oil sludge treatment system in China, GN solids control produced oily sludge treatment system has been widely used to treat crude oil tank cleaning sludge, refinery plant waste oil sludge, drilling waste oil sludge, contaminated soil washing system.GN standard design oily sludge treatment system with treating capacity 1~2m3/h, 5m3/h, 15m3/h for your different requirement. The basic treating process generally including:

Oil sludge picking up, normally we use sludge vacuum pump to pick up the oil sludge from waste pit to pre-mixing tank, we have nominal flow rate 10m3/h, 20m3/h and 40m3/h vacuum pump for option.
Heating and pre-mixing tank, depends on the treating capacity and oily sludge conditions, we can use 1 set or 2 sets of pre-mixing tank, 1 tank as heating, chemical jetting and pre-mixing tank, the submersible slurry pump will transfer the prepared oil sludge from 1# pre-mixing tank to #2 pre-mixing tank, which is also with heating lines to improve the oil sludge separation efficiency. With 2 units of premixing tank, the user do not need to wait until the chemical is properly mixed with oil sludge.
Coarse screening and heating tank, the prepared oil sludge, the double deck shale shaker will separate the coarse solids from the oil sludge
Chemical dosing and dewatering , the chemical dosing unit is installed inside 20ft container for convenient operation and maintenance. The oil sludge with fine solids will be mixed with proper chemicals will be sent to decanter centrifuge for solids liquid separation.
Solids liquid separation and heating tank, the decanter centrifuge can separate the solids from liquid with the chemical mixed oil sludge.
3 phase separation, oil ,water and little solids separation, the 3 phase disc stack separator will separate the oil and water and few solids, the oil can be recovered and water can be used in the circulation system.
