Drilling Waste Management Unit to Western Africa

    How exciting it is. Hebei GN Solids Control Co., Ltd will has its drilling waste management unit delivered to Western Africa.

    Generally, solids control system is designed to clean and recollect waste drilling by removing the useless solids. A complete line of equipment would be installed ,such as shale shakers, desander ,desilter( mud cleaner with the combination of desander and desilter is optional), and decanter centrifuge. In addition, for environmental reasons, solids which are separated from used drilling mud is not allowed to directly dump. To make a solution, drilling waste management is now applied.Drilling waste after uid content).

    Two ways are commonly seen to treat and recycle drilling waste: online drilling cuttings treatment and base mud recycling; offline wasted sludge disposal. Online treating is relatively easier and cheaper, the drilling cutting is directly transfer to vertical cutting dryer through the auger after discharged from shale shaker, while offline management will require more complicated processes for a satisfactory results. GN’s wast management unit belongs to the online treatment.

    The equipment list i ncludes:  one set of vertical cutting dryer,  one set of Netzsch Brand NEMO pump, one set of mounting decanter centrifuge, one set of vertical slurry pump, one set of oilfield 3 runner design skid ,  one set of accessories and electrical control panel system.

                                                                                                                                     .

    GN Solids Control is a leading manufacturer of solids control system and equipment in China, GN’s decanter centrifuge and vertical cutting dryer have been used in many waste management project. And, in such a beautiful fall, one GN’s drilling waste management unit is ready to go west Africa where she will service all through her life.

Shield Method is one fully mechanized underground construction Method. The shield machine will be pushed forward, the surrounding rock will be supported by shield shell and segment. At the same time, excavation of soil will be conducted at the front of the excavation face by cutting device; the soil will be carried out by unearthed machiner. After that, the shield machine will be pushed forward again by jack and assembling precast concrete segment, this is the general formation process of tunnel structure.

Tunnel Boring Machine (short as TBM) and Mud system is indispensable for tunnel shield project. TBM as main equipment, mud system as auxiliary equipment to make the TBM working in a high effeciency way. Recently, one Thailand customer bought one set 500gpm mud system to match with TBM machine for Tunnel shield project. Follow to read more about this case.

The 500gpm Mud System Technical Parameters

• One unit of double deck 6 panel shale shaker, GNZS706 with upside 3 panel coarse mesh shaker screen (2mm) and downside 3 panel fine mesh shaker screen ( 40mesh). The upside shaker screen area 2cbm; the downside shaker screen area 2.6cbm.
• One unit of mud cleaner or mud conditioner, GNZJ703-8N with 3 panel deck shaker and 8 pcs X 4inch desilter cones. The separation points 25-40 microns.
• One unit of centrifugal pump (37kw) for feeding desilter cones, the feeding pressure should reach 0.25-0.4Mpa; GN centrifugal pump is interchangeable with NOV mission pump. GN can also offer complete range of spare parts for NOV mission pump.
• Two unit of mud agitator (11kw) to suspend and mix the drilling fluids.
• Two unit of mud gun (2inch, fixed installation type) to working together with mud agitator.
• One unit of mud tank with 4 compartments.
• One unit of separate mud mixing unit, GN jet mud mixer with one mud hopper and one centrifugal pump (37kw). This unit can help supplement drilling mud to the system or add necessary chemicals or water.

Oil sludge separation system is ready to deliver to Kuwait. It is used as the 1^st stage of an oil recovery project of KOC for which a local service company makes the purchase from GN.

Component of the oil sludge separation system are listed below:

1 ea x GNCD930 Vertical cuttings dryer

4 ea x GNZS703D double deck shale shaker

5 ea x V-hopper with screw conveyor assembly at the bottom

10 ea x various pumps: shear pump, centrifugal pump, submersible slurry pump

To prevent cold weather in winter, the systems are combined with steam lines.
