In order to meet customers’ request and to help solve the problems faced in front of customers from the more and more strict environmental protection rules, GN Solids Control designed and put into market a comprehensive design for the oily sludge separation unit, and now GN Solids Control is leading in this industry.
In recent 3 years, GN Solids Control has customized several sets of similar systems, and such systems are being used in many different countries both in domestic China and overseas. It is widely used for treating the discharged slurry and sands from crude oil tank cleaning, oily waste discharged from refineries, and the viscosity oily waste from solids control for oil and gas drilling. It helps to reduce the cost for waste transportation and oil recycle, and gained good comments from under users.

OILY SLUDGE SEPARATION

A complete system is combined by several sections:
1. Pre heating and pre mixing system. In this system, a mixing tank with heating facilities are being employed. A chemical dosing system is used for adding some polymer or something else into the oily sludge and heating is used for reducing the viscosity. Later, the sludge is to be treated by a shale shaker, by which the large particles are separated out.
2. A high speed decanter centrifuge is used in next step for treating out the fine particles from the liquid. Floating unit is kind of oil water separation, and the light of weight oil will float on surface of liquid and it would be scraped out to an oil tank. The settled down particles would be drained from bottom of the IPC unit.
3. A disc centrifuge is used to separate out the small amount of particles from the liquid, and further separate the oil from water. Then the water flows into the water tank, while oil flows into the oil tank.
In the complete system, by using the complicated manifold and valves, the end user can bypass or invite into loop some equipment based on the sludge’s condition.

It is a common knowledge that in the solids control system for a drilling rig, no matter for the land rigs or for the offshores, the shale shaker plays the most important role for separating out the solids waste from the mud recycling unit, and it is also the shale shaker which waste the most of the liquid on the cuttings discharged from the shaker. That’s why, in many countries, there is a must to equip another drilling cuttings treatment system alongside the rig.
A drilling cuttings waste management system is used for further separation of the drilling waste discharged from the shale shaker and mud cleaner, most of which are from the shakers. For one thing, the drilling cuttings waste management system helps to dry the cuttings for later transportation, on the other hand, it increased the drilling liquid amount to be recycled. Both are saving money. In case of OBM mud, the operators always need a vertical cuttings dryer and a high speed decanter centrifuge, while for WBM mud, operators always use a high G drying shaker and a decanter centrifuge.
In some cases, the ViST Shaker screen device could replace the drilling cuttings waste management system, or at least to some degree, reduced the work for the cuttings separation works. Generally speaking, the ViST shaker screen device has following advantages:

ViST shaker device

1. It is suitable for both WBM and OBM mud in a solids control system.
2. It is a compact structure, and only use an air compressor as power source, and one set of ViST could serve up to 3 sets of shale shakers.
3. It is designed to be suitable for different shaker models.
4. In practice, it helps to save the liquid amount by 30% to 50%.
Now for GNZS703 and GNZS594 series shale shakers, there are ViST device for option.

In order to reach some separation results, especially in case of physical separation, the shale shakers always play important roles and handles most of the separation work. GN Solids Control is a professional separation proposal supplier and has various models of shale shakers. Those shakers are widely used in oil and gas industry and other drilling works, like the HDD, TBM and industry separations.

GN DOUBLE DECK SHAKER

GN DOUBLE DECK SHAKER

GNZS706E-HB Shale shaker, with 2 shaker deck and totally 6 pieces of shaker screens, is one of the best seller model among GN shale shakers. Main specification and features as below:
1. Shaker deck number: 2 decks.
2. Treating capacity: 120 cubic meters per hour.
3. Screen quantity: 6 pces, including 3 pieces of upper layer and 3 pieces of lower layer.
4. Screen size: upper layer size 2.0 m2, while lower deck layer 2.63m2.

Per experiences and calculated data, the drilling liquid occupies in any well drilling is between 4 percentage to 10 percentages, no matter in onshore drillings or offshore drillings. Considering its effects on the drilling operation performance, which occupies nearly 50 percentages, the drilling fluid is quite vital to the drilling.

GN Waste Management Equipment

That’s why, a professional drilling manager has to have a professional team for the drilling mud services, or find a qualified drilling fluid service company. In practice, drilling companies or drilling contractors always focus on drilling work, and employing a subcontractor for the solids control system. Each drilling rig has eight systems connected to each other, among which, the solids control system is comparably independent. An expertized drilling fluid company has the right personnel and suitable equipment, and more important, they know how to treat the fluid well.

A professional oil service companies provide following services:
1. Solids control equipment and services. The solids control systems help to treat the drilling fluid directly from the well mouth. It contains three or four phases for separation, including the shale shaker as the first phase, the desander cones as the second phase, the desilter cones as the third. Some include the decanter centrifuge as the forth one. In most solids control systems, there are mixing unit for adding more chemicals into the fluid when necessary.
2. Drilling cuttings waste management systems, in some countries, this part is also regarded as a part of solids control, because this is also for treating the solids from the drilling fluid. Those systems always contains the vertical cuttings dryer, the high G drying shaker and the decanter centrifuge.
3. Drilling fluid waste management, it is the further treatment for the drilling fluid. As the fluid has been used for a long time, this system uses some chemicals to flocculate the extra fine particles into larger ones before being separated out by a decanter centrifuge.
As one of the leading manufacturers of solids control and waste management, GN Solids Control has been providing lots of oil service companies in the world for all above mentioned systems and equipment. For more information or a formal quotation, welcome to contact GN directly.
