Oil sludge separation and Waste management

BY admin 2 May 2023 Decanter Centrifuge, drilling mud centrifuge, mud recycling

GN Solids Control will ask for pictures and / or videos of the raw waste sludge to design and implement the different phases of clients’ project for the waste management coming from the Oil & Gas sector.

GN Solids Control offers 2-phase separation and 3-phase separation treatment on oil base mud (OBM), oil sludge treatment solution, tank cleaning, vessel cleaning, etc…

The 2-phase separation treatment: It is for liquid and solids separation. Most clients only need to reduce the solids waste and recover the usable drilling fluids for reuse. In this situation, they will choose 2-phase separation system.
It is more popular and the process is relative easier. Oil base mud and water base mud is used for different drilling sections. The separation equipment for OBM and WBM is different. The major separation equipment for OBM cuttings is vertical cuttings dryer. It can reduce the oil on cuttings to 5% and less.

If for water base mud, high G drying shaker is used to reduce the liquid content.

After vertical cuttings dryer and High H drying shaker, decanter centrifuge is used to remove the fine solids in the recovered fluids which comes from cuttings dryer with high content fine solids content. The purpose of the centrifuge application is to reduce the mud weight to make it suit for reused. After high speed centrifuge separation, the fluids will go back to solids control mud system for drilling activities. Some time, will use chemical dosing system for flocculation.

Another option is more complex, it is 3 phase separation: it means the separation of solids, water and oil. GN Solids Control have both 2-phase and 3-phase centrifuge. 3-phase centrifuge can only allow slurry with less than 3% solids contend. In this case, clients have to use 2-phase centrifuge before 3-phase centrifuge. But while treating the sludge with less ultra fine particles, clients can use 3-phase decanter centrifuge or disc centrifuge to separate oil and water.

Mud Cleaning system and drilling fluids decanter centrifuge for international drilling company

BY admin 19 January 2021 CBM drilling, Decanter Centrifuge, Drilling equipments Company, drilling mud centrifuge, Drilling mud system, HDD machinery, mud recycling, No Dig Mud System

A customized drilling mud processing system is is ready for shipment at GN Solids Control Beijing factory. It mud cleaning system is composted of a mud cleaner, a mixing hopper, and a centrifugal pump for mud mixing and transfer.
The drilling mud cleaning and mixing system is designed and made by client’s request to suit his drilling mud situation. Normally, mud cleaner is equipped after a pre-seperation shale shaker. But in this mud cleaning system, the first separation equipment is mud cleaner.

Drilling Mud Cleaner

The reason why the client do not use shale shaker is that, they said the solids content in the mud is not much high. And mostly are fine solids. In this case, the drilling mud can be separated by mud cleaner directly. It is to save cost. As once the shale shaker is running, clients need to replace shaker screen periodically. It is a continue cost for operation. While delete the shale shaker, the system can meet client’s request. It can save the cost of shale shaker, and furthermore, the can reduce wearing spare parts shaker screen cost.

But if the solids content is high, or the particle side is big, which is over the hydracyclone separation point and its mud handing capacity, it is better to use a shale shaker before the mud cleaner. At one hand, the shale shaker can reduce the flow rate which feed to the mud cleaner. At another hand, after the shale shaker separation, the solids content will be reduced, and the big size particle are total removed based on the shaker screen API size and cut point. It can increase the hydraucyclone separation efficient, and also to avoid the fast wear out the hydraucyclones. 10 inch desander cone and 4 inch desilter cone are the most popular cyclone sizes used for drilling fluids separation system. Operator can choose the to use only desander cone or desilter cone, or both based on the mud condition and their budgetary. Desander and / or desilter cone quality depends on the handling capacity of the whole system.

Drilling Mud Centrifuge

Feeding pump for mud cleaner is centrifugal pump. The centrifugal feed pump is located on tank slope for compact design and for maximize the total tank usable volume.

After the mud recycling and mixing system, a drilling mud decanter centrifuge is used for fine solids separation. As there will be more and more fine and ultra fine solids after some circulation of the system. Decanter centrifuge will be used to reduce the mud weight.

GN Solids Control is focusing on the full package of drilling mud processing system. As GN Solids Control makes full line drilling mud processing equipment. They know well about the equipment. GN Solids Control can offer professional proposal of drilling mud treatment system and mud mixing unit. All processing equipment and the tank volume should be match to each other.

For example, if the total shale capacity is max. 160m3/4 or 200m3/h, but the desilter and desilter capacity is 240m3/h. And feeding centrifugal pump and mixing pump are 55kw or above. The system is not reasonable. As the 1rst stage separation equipment, the shale shaker capacity should be bigger than the next step separation equipment. Otherwise, if the mud flow is big, the shale shaker will overflow. Or if the mud flow is small for the shale shaker to handle, but the desander and desilter pump are too big, it will cause pump suction air. And the hydrocyclone separation performance is not good in condition the feed flow is too small. The client need to increase shale shaker capacity, or decrease pump and mud cleaner capacity to suit for the mud pump capacity.

Every jobsite is different. Every client has his preferable. In order to offer a suitable mud system design to suit for the job site situation, as well as client’s special requirements. Below are some questions to let GN Solids Control knows more about clients request.
