Recently GN shipped one set of water based drilling cuttings disposal system to Africa, firstly the client use water based drilling cuttings treatment system to treat the drilling waste firstly, to reduce the moisture of the discharged cuttings as much as possible, so the user can use less lime and absorber material and save the cost to reach better solidification result. The working principal of the cuttings solidification unit is to use lime and absorber to mix the drilling cuttings and prevent the waste from leakage to the environment, and safe for landfill and other construction works.
The solidification unit configuration is as below:

Installed one 2 separate skid for flexible operation, one skid is drilling cuttings collection hopper to receive the water based drilling cuttings and transferred by screw conveyor to solidification mixing skid; the other skid is solidification mixing unit including lime storage box, absorber storage box, with 2 auger to transfer the material to high shear mixer, the materials are mixed by high shear mixer and transfer to the solids discharged port, the hazardous waste are locked into the discharged solids, so that it can be safe to the environment.

High G drying shaker is a 4 panel screen shale shaker, the shaker screens installed is composite material frame shaker screens, 2 nos of 1.94KW vibration motor provide high G force up to 8.0G, the hopper type buffer box to receive the drilling cuttings from the auger discharge port.
VFD decanter centrifuge to separate the fine solids from the drilling waste, if necessary, flocculants should be added to increase the separation performance, the fluids will be more clear, and the discharged solids is much drier. The max speed is up to 3900rpm, max G force is 3063G, the typical speed is 3200rpm, the typical G force is 2062G.

Three phase separator produced by GN solids control is used to separate the oil from water for refinery oil sludge separation project. There are 2 options for the 3 phase separation unit, one is to use three phase decanter centrifuge, the other option is GN standard 3 phase separation package.

Three phase separation package is consist of 2 phase decanter centrifuge and feed by screw pump, buffer tank to receive the discharged fluids and to be transferred by diaphragm pump or slowly flow to disc centrifuge for oil and water separation, the oil is recovered and back to the client, the water will be collected and re-used in the circulation system. By using proper demulsifier, the recovered oil can reach to BS &W below 3%. The water to be collected with oil content 500 ~ 1000ppm.

The 2 phase separation decanter centrifuge with VFD control panel is used to separate the ultra fine solids up to 2 microns. The max speed is 3900rpm and the normal working speed is 3200rpm, the max G force is up to 3063G and typical G force is up to 2062G, if necessary, the used can add proper chemicals to accumulate the ultra fine solids for easier separation by gravity difference. The disc centrifuge can provide high G force to separate the oil from water after discharges by decanter centrifuge.
Another option is oil water separator, the separation result is not as good as disc centrifuge, but the capacity is much bigger and the price is cheaper. The 3 phase separation package can be used for most type of oil sludge waste treatment, like Crude Oil storage tank cleaning sludge, Refinery plant waste oil sludge, Drilling waste oil sludge.

As one of the professional oil sludge separation system manufacturer in China, GN solids control can design and produce customized system for our clients working for oilfield environmental solution company, refinery tank bottom cleaning company, oil sludge treatment facility, oil waste water treatment company, oil waste disposal company, etc. Recently we have one set of oil sludge separation system ready for shipment, if you are interested in a solution for oil sludge treatment, pls contact with GN sales engineer to check the system.

A basic oil sludge separation system including: sludge transfer unit, pre-mixing modular, coarse solids separation modular, fine solids separation modular, 3 phase separation modular, chemical dosing unit, oil storage tank, water storage tank and other accessories. The most important modular is fine solids separation modular and 3 phase separation, the other modular might be replaced or removed depends on the client’s requirement and site situation.

A decanter centrifuge with positive pressurized VFD control panel is used to separate the fine solids from the oil / water mixture liquids, proper chemicals should be used in the process to improve the separation performance, the fine solids should be separated as much as possible so that the next step 3 phase centrifuge can separate the oil and water with good result, without blocking the equipment. Before feeding to the decanter centrifuge, no solids bigger than 1mm remained in the oil sludge should be ensured, it might influence the centrifuge working life and lead it to blocking easily.

The 3 phase centrifuge is to use to separate the oil from water, and oil will flow to a small tank, when the liquid level reach the setting limit, the oil pump will pump it to the storage tank automatically, which will be recovered by the refinery. The recovered water can be re-used in the circulation to be used for mixing, heating and flushing.

GN Solids Control can provide customized solution for oil sludge treatment unit, the core equipment is decanter centrifuge, which can separate the fine solids from the fluids mixture, the separation performance highly depends on the working and quality of the decanter centrifuge. When use the decanter centrifuge, the user should ensure that coarse solids are already separated out in case that the big solids will block the centrifuge bowl and the screw will be damaged easily because of high solids content.

The fluids discharged from decanter centrifuge will flow to a intermediate tank, then to be pumped to three phase centrifuge to separate oil and water. The recovery oil will be storage in a oil tank, the discharged water will be storage in the water tank or reused.
The working principal of decanter centrifuge for solids and liquid phase cleaning:
The oil sludge is feed to decanter centrifuge inlet pipe, and push to centrifuge bowl from screw fluids distribution port by centrifugal force. The oil sludge is rotating with the bowl under high speed up to 3900rpm, the normal working speed is 3200rpm. The centrifugal force is much more higher than gravity. With the great centrifugal force, a fluids ring is generated along with the bowl inside wall, because of the density difference for solids and liquids, the solids is heavier than liquids, which will generate bigger centrifugal force, so it is settled down to the fluids discharge port.
GN big bowl big volume decanter centrifuge GNLW554EP is the ideal model to treat oil sludge with higher treating capacity, the bowl diameter is 550mm, the bowl length is 2310mm, the higher L/D ratio 4.2 will treat the oil sludge better and cleaner. The Netzsch brand screw pump will be used to feed the different material to decanter centrifuge for stable working.

GN solids control will participate in India HDD exhibition held in December, 2019, Welcome to visit our stand at NO DIG SHOW or make an appointment by Teresa@gnsolidscontrol.com .

Below is the working photo of oil sludge separation system at site, they install the complete unit under the awning to proof the sunshine, rain, snow. The most essential component is 3 phase separation modular, which consist of below equipments:

1) 2 phase decanter centrifuge to separate solids from fluids, to make it easily separation, the operator can add chemicals to the static mixer through chemical dosing system and then to centrifuge feed tube, the chemicals will accumulate the solids size for easier separation by decanter centrifuge.
2) The fluids discharged from decanter centrifuge will flow to a intermediate tank, then a small diaphragm pump will pump the mixture fluids to a disc centrifuge to separate the oil from water. The clean fluids will flow to a oil tank for temporary storage, once it reach the limit level, the oil pump will pump to a big storage tank automatically. The water will pump also be pump to a water storage tank automatically when reach the level limit.

3) By adding proper chemicals, the recovered oil BS & W below 3%,the discharged solids with oil content can be treated to 1% o 2%. The recovery water with oil content below 1000 ppmv, if the client need it to be below 30 ppm, we need to use further oil water separator after 3 phase centrifuge also by working with proper chemicals.
4) All the equipments, liquid level meter, intermediate tank, lightings, are installed on the same skid for convenient transportation and operation. Proper lifting points are provided on the four corners of the skid.
