This week, a full package of compact oily sludge separation system was finished from GN factory in Beijing China. The compact design fast movable oily sludge treatment system is purchased by a reputable Environmental Solutions Company from China domestic market.

There are 3-stage separation equipment included in the oily sludge treatment system.

1) There is a 2-panel small footprint shale shaker equipped in the system for coarse solids separation. The model is GNZS752. As mostly, the oily waste come out from different sources and it is mixture of different wastes. There may be big size solids in side. The big sides solids may block or even broken the centrifuges. The small size shale shaker is used to remove the possible big size solids in the sludge.

2) There are 2 centrifuges in the oily sludge treatment system. The first centrifuge we call it decanter centrifuge. The decanter centrifuge model is GNLW224, it is a 2-phase separation centrifuge. The 2-phase decanter centrifuge is help to remove solids or soil from liquid mixture. The 9 inch centrifuge is a min size decanter centrifuge. The bowl diameter is only 9 inch, but the bowl length and diameter ration is up to 4. The longer ration can help to get cleaner liquid. It is the smallest centrifuge from GN Solids Control for industry separation.

3) The second centrifuge inside the oily sludge treatment system is disc centrifuge. It is also called 3-phase centrifuge. As the name mean, the disc centrifuge can separation oil, water and soil.

Many people may wonder: in case the disc centrifuge can separate and get oil, water and soil. While you add 2-phase decanter centrifuge inside the system? Really, the 2-phase decanter centrifuge is surely not to increase the cost. The disc centrifuge can only allow liquid mixture with liquid content less than 3%. Otherwise, it will damage the centrifuge. While the decanter centrifuge can allow liquid with solids content up to 15% ~ 20%. Decanter centrifuge is a necessary as pre-separation before disc centrifuge.

Thermal desorption unit is normally known as TDU. It is a kind of Ultimate equipment for oily waste management. The Thermal desorption unit (TDU) is a High-tech products, few company has the capability and technology to make it.

GN Thermal Desorption Unit is an ex-situ, non-incineration technology. It is designed to separate hydrocarbons from various matrices including oilfield drilling cuttings waste, oil based drill cuttings, oily contaminated soil, oil sludge and sand, filter-cake, tank and tanker bottoms, organic-based hazardous waste and contaminated soil in a non-oxidizing atmosphere without destroying the hydrocarbons. The TDU technology has been used extensively for waste management, the main function is for recovery of the oil from the waste material as a sellable product throughout the world.
Many clients showed great interest on the design of GN Thermal desorption unit (TDU) technology. There are mainly 2 designs developed by GN Solids Control.

From 2015 to June, 2016, GN Solids Control have been working on the design of the drum type TDU. But GN stopped that project after 2016. After that GN Solids Control shift to design the screw type TDU from July, 2016. So now, GN Solids Control does not make drum type Thermal desorption unit (TDU).

GN Solids Control latest design on is similar to TPS, but not TPS, TPS is a single screw in one tube, with different tubes.

GN Solids Control design is as following:
1) One tube, two auger system for self cleaning, it’s better than the single tube system.
2) Temperature can go up to 700 C degree which suits the drilling cuttings and oil sludge to recovery oil and water.
3) GN Solids Control have a dust removing unit before condensing, so it makes it easier for oil water, solids separation.
GN Solids Control already have the major components, like tube material, burners, air lock valves and Fin-Fan coolers etc in the factory to shorten the manufacturing time.

For any questions, please contact GN Solids Control sales team for support.

GN Solids Control made an oil-based drilling cuttings treatment system for a CNPC company. GN Solids Control made and designed and system per client’s job site situation. So it can suit for the clients’ situation well. Clients are happy with the performance of the OBM treatment system. Both the team leader and job site workers are satisfied with the system, and they said that, after applying GN waste management system. They can recovery more usable drilling mud. Their drilling waste and their drilling cost are both reduced. And they can save cost and manpower on the waste material shipment.

The oil based mud treatment system made for CNPC is a complete package. It is a skid mounted cuttings drying system with processing equipment, mud and cuttings transfer equipment, and electric control system.

Below is the major equipment included in the skid mounted oil based mud cuttings drying system:

Firstly, there is a vertical cutting dryer. The vertical cuttings dryer is mounted on a separate skid. VG dryer is also called VG centrifuge, it is the major equipment to treat the oil based mud and cuttings discharged from shale shaker. GN high quality vertical centrifuge can reduce the oil on cuttings to as low as 3% ~ 5%. In many countries and regions, less than 3~5% OOC can be discharged directly. Even not, it is already very dry like powders. It is easy for movement and for next process treatment.

Secondly, there is a 14 inch decanter centrifuge in the oil base mud cuttings drying system. The decanter centrifuge is used after the vertical centrifuge to reduce the mud weight. Enable the recovered mud qualified for drilling activity.

3 sets screw conveyors are equipped in the system. One screw conveyor is located under the shale shaker to collect drilling cuttings discharged from shale shakers. Another screw conveyor is located inclined to transfer the cuttings from shale shaker and feed to the vertical cuttings dryer. The 3rd screw conveyor is inclined and under the vertical cuttings dryer. It is used to transfer the drying cuttings from VG dryer to the cuttings containers.

GN Solids Control is the 1st one manufacturer in China who ever sent the drilling cuttings solidification unit to client’s jobsite. It was predictable that many comments regarding the performance of GN solidification unit would come back. More important is how to response to these comments.
GN is always keeping developing new products, which is the reason of the first unit drilling cutting solidification unit coming from GN. Some of the comments on GN solidification unit are positive, while some are very good suggestions for GN to perfect the design. The unit sent to site was designed whole assembly installed on one skid, which makes the unit too long to move and locate the unit easily. The new design divides the machine into 2 parts; one is for solidification agent storage, the other part is for mixing. These 2 parts could be located more freely according to the site space. Comparing with old model, the new one has larger tank for agent storage, on top of the tank, hand rails are installed. The agent bag pallet could be put on top of the tank, which greatly increases the working efficiency. Though 2 parts, the whole system still could be put into one 40ft container for oversea transportation.

Cuttings Solidification Unit

The drilling cutting discharged out of the shale shaker and decanter centrifuge could be fed into the solidification unit for treatment. However, there is a misunderstanding on the performance of the solidification unit: No matter how wet the cutting is, so long it is fed into the solidification unit; the dry material will come out. This is not correct. The much wet the cutting is, the more solidification agent will be used. Hence, the operator should make the cutting as dry as possible before feeding into the solidification unit.
GN’s solidification unit was proved greatly saved the man power on site as it can working continuously, the speed could also be adjusted as per the working condition. Solidification unit is one of the final solutions for water base drilling cuttings. Easy operation and maintenance are its advantages.

Pitless means no need to dig a pit on the ground to collect the drilling cuttings. Nowadays, though the solids control system is widely used in oil drilling, some drillers still dig a mud pit on the ground to collect the drilling waste cuttings discharged out from the primary solids control equipment.
So long as the drilling rig is working, the solids control system has to be working all the time as the used drilling fluids is continuously coming out from the drilling well. With the issue of much strict environment protection regulation, the driller need find a solution to reduce the volume of the discharged drilling cuttings; in the meanwhile, much more drilling fluids could be recovered to reduce the drilling cost. And then they got a
conclusion, if I can establish a pitless drilling cutting disposal system, all the problems would be solved.

pitless drilling cuttings disposal system

Pitless Drilling Cuttings Disposal System GN

Pitless drilling cuttings disposal system requires a good connection between the traditional solids control system and waste cuttings management system. The most important is there should be a final solution on how to make the discharges environmental friendly. For the waste cuttings out of the shale shaker and cyclone unit, no matter water base or oil base. We have the high G force drying shaker and vertical cutting dryer unit to make the cutting much dryer so that more drilling fluids could be recovered. The recovered drilling fluids would be pumped
to a high speed centrifuge for separation of fine solids in the drilling fluids. After treated by the centrifuge, the drilling fluids would flow back into the storage tank for drilling reuse. The screw conveyor is used to transfer the drilling cuttings from shaker unit to the cuttings dryer machine. Therefore, it is no need to dig a mud pit, or at least, a large and deep mud pit on the ground to collect the drilling cuttings. We nearly realize
the pitless before the final disposal of the dry cuttings.
There are Thermal Desorption Unit and solidification unit could be used to dispose the cuttings from the high G force drying shaker and Verti G dryer. These 2 systems could make the cuttings none hazardous for environment. Finally, the pitless drilling cuttings disposal system is established.
