Equipment to treat Drilling cuttings offshore rigs

Recently, GN Solids Control got inquires from clients for the drilling cuttings treatment. Below is the client’s request.
They are proposing to use the cuttings blowing pump for drill cuttings transfer and disposal from an offshore jack up rig to a dedicated barge. The clients want to treat both OBM and WBM contaminated cuttings.

In addition to this, they will require some other equipment as follows:
Cuttings storage system: Bulk storage and retrieval systems 150bbls discharging at 30mt/hr
315hp, 1260cfm 150psi twin air compressor if available
100HP vacuum unit for spill containment (750 gal volume and 1600cfm flow)
40tph vertical cuttings dryer (DRY TO BELOW 5% OOC RATIO)
And they give note that it is of great importance that all equipment must be explosion proof.

Based on the client’s need, our sales people keep communicating with them for a suitable proposal for them.
The cutting transfer way can be effected by vacuum pump or screw conveyor. Vacuum pump is widely used to transfer oil sludge, 100% air running/operation, it can use for some special jobsite
Vacuum pump running video link, FYI: http://www.gnsolidscontrol.com/video/gn-drilling-cuttings-or-sludge-vacuum-transfer-pump-working-video

We have triple skip station to collect and transfer cuttings, and send drawings to clients for reference. Screw conveyor is another way to collect and transfer cuttings from mud processing equipment to the cuttings storage equipment.

And vertical cutting dryer is GN advantage. The Vertical cuttings dryer is mainly used to treat OBM cuttings. For WBM cuttings, GN recommended to use High G-Force drying shaker instead of vertical cuttings dryer to separate. GN attached some complete cutting management solutions for reference. And clients can also check jobsite videos on GN website.

GN Solids Control is leading manufacturer on solids control and waste management equipment. GN is also manufacturers for different models replacement screens. GN owns factories in Beijing China and have a big warehouse in Houston. Clients can visit GN website or contact GN sales team to get support.

GN Oil Sludge Treatment Decanter Centrifuge for Sale

GN Oil Sludge Treatment System is to use chemical to wash the oil sludge  with heat to temperature of 60-70 C degree. After washing the oil sludge  is pumped to  GN separation equipment to separate into oil, water and solids. The recycled water can be reused in the washing process which save a lot of cost to reduce the consumption of clean water, and the oil is clean enough to sell to the refinery company, the solids contain oil between 2%-3% which can be sent to biodegradation or thermal unit for final disposal.

The main components for oil sludge treatment include slurry transfer pump, pre-mixing slurry tank, primary shale shaker, decanter centrifuge, 3 phase disc vertical centrifuge, chemical dosing system, storage oil tank , storage water tank.

  • Slurry Transfer Pump: The vacuum pump can be used to pick oil sludge from the pit and feed to the pre-mixing and heating tank. At this stage, chemical dosing system will feed chemical the mixing tank to improve the separation of the oil water and solids.
  • A submersible is used to pump the slurry to feed to primary shale shaker for separation of coarse solids from the oil sludge.
  • The screen on the shale shaker normally use 2 mm opening screen, after separation by shale shaker, a second pump which is a screw pump will pick up the fluids with fine solids and feed to the decanter centrifuge. The decanter centrifuge is the core equipment for the oil sludge treatment.
  • After decanter centrifuge, the relatively clean fluids will be sent to a 3 phase disc centrifuge to be separated to water, oil and fine slurry.
  • Later on, the water can be used to washing and mixing the slurry, the recovery oil will be sent to the oil storage tank.

Double deck shale shaker for big capacity and better performance

According to the deck quantity of shale shakers, there are different forms of shale shakers:
1) The most popular is single deck shale shaker, for example: GNZS703, GNZS752, GNZS594 shale shaker, Derrick FLC 2000, FLC 500, DP 600 and Hyperpool series shale shaker, NOV Brandt Cobra, King Cobra, Mini Cobra, Venom and D380/D285P shale shaker, MI-Swaco MONGOOSE PRO, MONGOOSE PT & MEERKAT, ALS series
shale shaker

Dual tendam shaker

Dual tendam shaker

2) Double deck shale shaker is also popular as the obvious advantages on performance. For example: GNZS705, GNZS706, GNZS753; Brandt LCM-2D, MI-Swaco MS-2, and so on.
3) There are also many 3-deck shale shakers, like Brandt LCM-3D, MI-Swaco MS-3, NOV Brandt VSM300 series, etc…
The most popular shale model is single deck, as it is easier for operation and maintenance. Double deck shale shaker is also popular as the obvious advantages on performance. Below are some of the advantages of double deck shale shaker.
1) With the same bottom screen areas, the double deck shale shaker can handle more capacity. The double deck shale shaker can utilize big opening screens on the top deck for pre-separation, and then use a normal size or even finer size on the bottom deck.
2) The double deck shale shaker means 2-step separation, it can recovery more drilling fluids and it is more clean. With the same handling capacity, the top deck can remove the bigger size cuttings, and then the bottom screens can use a finer size screens for a better separation result.
3) Although the double deck shale shaker owns more screen quantity per unit, but as on the top deck, operators can use big opening steel screens to remove big cuttings, the big opening steel screens can last for a much long time compared with traditional wire mesh screens. And as the big cuttings will be removed by the top deck steel screens, it can protect the bottom wiremesh screens. The total screen cost for operators may be lower.
Although the double deck shale shaker has obvious advantages, but it is still not as popular as the single deck shale shaker. Why? The main reason is that, as there is a screen deck on top of the bottom screen deck, operators cannot easy observe the damage of the bottom screens, and operators have to remove the top deck screens in order to watch the situation of the bottom deck screens or to replace the bottom deck screens.
