GN Solids Control makes drilling mud treatment equipment for onshore and offshore applications. The material standard and the design for onshore and offshore application are different. This week, GN Solids Control just finished the fabrication and commissioning of a set of solids control equipment for offshore projects.

A 18 inch big bowl decanter centrifuge is included in the project. The big bowl high speed centrifuge is specially design to suit for the offshore applications.

Below is the major different of on shore decanter centrifuge and offshore decanter centrifuges.
Firstly, the control panel Enclosure material for onshore rig and offshore rigs are different. Casting aluminum Enclosure is the most popular. But the material is not durable than while used on the sea. It must be stainless steel enclosed for more durable.

Secondly, the paining standard for onshore and offshore equipment is different. Powder painting is good enough for on shore equipment. It looks nice. But the marine situation is very much abrasive. Powder painting is not durable enough. The normal painting is with more thickness. It last longer time. And ever for the normal painting, it is corroded more fast than on shore, and need to repair more frequently.

Thirdly, the material of sealing rubber parts for onshore and offshore are different. The Nitrile rubber material is widely used and good for on shore. It is durable for oily material. But Nitrile rubber is not durable for offshore. It must be Fluororubber material, which is more durable under marine and chemical corrosion situation.

Fourthly, the offshore equipment has high request on the lifting standard. GN Solids Control makes additional lifting frame and crash frame for equipment used on offshore platforms. And mostly, the offshore project will request special lifting certificate to ensure the equipment complied with offshore job site.

And plus, there are various standard explosion proof, China National explosion proof, EU standard ATEX explosion proof, International standard IECEX explosion proof. And for offshore applications, in many cased, the end user will request the marine explosion proof.

The traditional drilling mud solids control equipment includes shale shaker, mud cleaner, desander, desilter, decanter centrifuge, etc…Each of them has a certain cut point (separation point). They are selected and used based on their cut point.

Solids control shale shaker is the basic and pre-separation equipment of drilling mud system. Its cut point is up to the screen opening utilizing on the unit. In order to make sure the accurate and correct separation result, API RP13 complied screens are requested to used in the drilling mud shale shaker. It means all API RP13C screens with the same API size from various screens manufacturers are all interchangeable. They can all reach the same cut point.

But for various screen suppliers, their screen quality and the mud flow rate varies based on the materials and the designations. There are API screens with sizes from PI 10 to API 325, the cut points is from 2mm to 40 microns. The finer the API size, the less the mud flow rate.

Screen shale shaker is the D100 separator. It means 100% particles above the cut point will be removed.

10 inch hydro cyclones are the post popular used in oil and gas drilling for desander. It is also called as desander cone. Its separation point is 47 microns. In some cases, 12 inch hydro cyclones are used for bigger mud handling capacity.

4 inch hydro cyclones are the post popular used in oil and gas drilling for desilter. It is also called as desilter cone. Its separation point is 25 microns. In some cases, 5 inch hydro cyclones are used for bigger mud handling capacity. The smaller size 2inch desilter cone were used in some special drilling waste management situations.

Hydro cyclones are not D100 separator. Hence the underflow shale shaker is suggested to used under the hydro cyclones to further clean the solids discharge from them.

Decanter centrifuge is a high standard and precision separator. Its cut point can up to 2 ~ 5 microns. It is used to reduce the mud weight.

GN Solids Control offers professional proposal for various kinds of oily sludge separation application in oil field. The oil sludge includes oily waste from tank cleaning, from drilling mud system, from waste pits, from crude oil storage tank, from refinery, and so on.

Oil sludge is a mixture waste which is consisting of oil, water and solids, soil. The treatment of the oil sludge wastes is normally to recover as much oil and water for reuse, and reduce the solids waste. And some times, it will request 3 phase separation of oil, waste and soil. Also it is an ideal solution to for the solids disposal. It is also good for environment protection. If more oil and water recovered, more energy and resource could be saved. And the waste material is reduced.

GN oil sludge treatment plant mainly include shale shaker separation and decanter centrifuge separation, oil water separators and waste waster water treatment unit.

There are generally 3 solutions of oil sludge treatment, in order of separation effect and the investment, the 3 solutions is as following:

Option 1 Shaker modular + 2 phase centrifuge centrifuge modular: If the customer only requires solid-liquid separation, and does not require oil-water separation, use shale shaker separation with 2-phase centrifuge centrifuge.

Option 2 Shaker modular + 3 phase centrifuge centrifuge modular:
If the customer requires three-phase separation of oil, water, and slag, but the requirements for three-phase separation are not high, use shale shaker separation, and 3-phase decanter centrifuge.

Option 3 Shaker modular + 3 phase centrifuge centrifuge modular + 3 phase disc centrifuge modular:
If the customer requires three-phase separation of oil, water, and slag, and the requirements for three-phase separation are relatively high. Use shale shake separation, 2-phase decanter centrifuge, and three-phase disc centrifuge. The advantage of a three-phase disc centrifuge is that it can get clean water and oil, but the disadvantage is that it is easy to block.And the cost is higher.

GN Solids Control makes various transfer pumps and transfer equipment for drilling mud and drilling waste material carrying and transfer, such as centrifugal pump, slurry pump, solids and sludge vacuum pump, screw conveyor, etc…

Centrifugal pump is used as feed pump for mud cleaner, desander and desilter. It is used as suction tank for mud pump. Centrifugal pump is used as transfer pump between tanks. Centrifugal pump is also used as mixing pump for mixing hopper and shearing hopper.

Slurry pump can transfer bigger size solids and bigger percentage slurry compared with centrifugal pump. GN Solids Control makes horizontal slurry pump and vertical slurry pump. The big size slurry pump is normally used to feeding for shale shakers. The small size slurry pump can be used to feed for decanter centrifuge.

GN Solids Control makes big model skid mounted vacuum pump and portable type small vacuum pump. It is a 100% air driven pump without any electric components. And there is no rotating parts inside the vacuum pump tank. It enable the pump or big size solids transfer, reliable performance and less maintenance.

If you have missed to meet GN in the past exhibitions, there is still other changes. Welcome you visit GN at CIPPE Beijing oil show at end of May, and the ADIPEC in Abu Dhabi early Oct.

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.
