Scew Conveyor

Screw conveyor is a transportation equipment widely used in waste management field. Drilling cutting screw conveyor is mainly used to collect drilling cuttings separated from solids control equipments, like shale shaker, desander, desilter, barite recovery centrifuge,etc…Then the drilling cuttings will be fed to high G shaker or vertical cutting dryer.

Swivel screw vconveyor

Drilling waste management screw conveyor can be used in level or with an angle. The angle must max.  40°.

While use with angle, in most condition, the angle is fixed. For some situations, users want a more flexible application. In this case, the leading solids control and waste management manufacturer- GN Solids Control design and make a swivel screw conveyor. GN equipped swivel at the underneath end of the screw conveyor and also equipped swivel caster underearth the frame. In this case, the swivel have the function to move at any direction easily.

The swivel screw conveyor with an adaptable height. Furthermore, users can change angle of the screw conveyor both in horizontal and vertical direction .

Parameter of swivel screw conveyor

All kind of screw conveyor can be designed for swivel. GN has 2 auger dimension for choice: 14’’ and 18’’.

For length, GN have 12 feet standard length for each selection. Namely, users have 12 feet, 24 feet, 36 feet, 48 feet for option. For safety consideration, GN max. match 48feet, namely 4 selections for each screw conveyor.

Water based drilling mud as well as oil based drilling mud are the most popular drilling mud for oil gas drilling.As the regulations for the environmental protection are bringing out by the gorvement in many countries, the requirements to the treatment and disposal of the drilling cuttings are increasing.

As a Solids Control & Waste Management equipment manufacturer, GN Solids Control  design and manufacture Vertical Drilling Cuttings Dryer, High G Cutting Dryer, and Decanter Centrifuge. To reduce the disposal for water based drilling cuttings, GN normally provide the High G Cuttings Dryer for drying the solids discharged from shale shaker, mud cleaner, or Desander Desilters.

About microtunneling

Microtunnelling is a nature method of construction using pipe jacking. In many countries and areas, it also defined as a “Trenchless Construction Method”.

Slurry separation system for microtunneling

Microtunnelling project usually takes in urban district. In this case mud system matched for microtunneling request compact and a very small footprint recirculation slurry system with different capacity. This kind of mud system usually called as “slurry separation system”.

Features of slurry separation system

1) Steel Frame Screen with large open microns usually used.

As the solids usually bigger than oil and gas drilling, solids content higher and many bigger size sands / solids. And it is big diameter well with smaller depth, no higher request for mud quality. It is no need to separate very fine. And steel frame have a longer lifetime for microtunneling.

2) Compact system with smaller footprint: all separation equipment combined together, a storage tank and a mixing tank.

Usually, GN only offer separation plant and equipment for mixing part. And recommend users to build storage / mixing tank locally to save cost.

3) Big size hydro cyclones for large capacity. And it is not easy to be blocked.

Nigeria oil drilling market requires a lot of vertical cutting dryers, GN has already supplied Vertical Cutting Dryer (Vertical Centrifuges) to Russia,Brazil, Libya and China.

GN Solids Control also have very good busines in Nigeria for Solids Control Equipment & Decanter Centrifuges.

About GN Vertical Cuttings Dryer:

In drilling operations, typical solids control equipment discards 1-4 barrels of liquid for each barrel of solids removed.GN drilling cuttings dryer system consisting of Vertical cuttings Dryer and the relevant equipment could discharge 1 barrel of liquid for 3 barrels of solids removed.GNCD930 has proven to reduce this liquid to below 3% by weight by site test：

• 1) Reduce the amount of OBM or SBM on cuttings discharge to reduce waste volume and meet environmental objectives.

• 2)  Recover valuable base fluids for reuse and lower the cost.

• 3)Reduce fluid content prior to other treatment, thereby increasing process capacity.

GN Vertical Cuttings Dryer Structure Features:

In short，GNCD930 Vertical Centrifuge could help you meet environmental objectives by reducing waste volume, maximizing liquid recovery and reducing your project cost.GN Solids Control can provide all-around mud recycling and treatment equipment.

n the design process of GNCD cuttings dryer, user maintenance is taken into full account. All wearing parts are easily removable belt can also be replaced without disassembling the gear box, and the gear box part can easily be removed.

GNCD dryer is designed for high-speed rotation industry work, and take full account of the dynamic balance. Each rotating parts have been done a dynamic balance, in order to ensure that the replace part does not affect the whole dynamic balance.

The gear box is used to offer differential speed between screen basket and screw pusher. As the gear box is an integral structure, whole replacement is required. GNCD dryer has independent external circulating oil lubrication system. The lubricating oil pump and the filter device are arranged outside the GNCD dryer for easy operation and maintenance. To ensure sufficient lubrication for gear box and bearings, a pressure control switch and the flow control switch is needed in this lubrication system. To ensure the normal lubrication, these switches are connected with host or alarm.

The horizontal Solid Bowl decanter centrifuge design by GN Solids Control is very popular for oilfield drilling mud solids control application of drilling waste management system.

The centrifuge are the solid bowl, horizontal, continuous feed, scroll type specifically designed for drilling mud processes to continuously separate one solid and one liquid phaseMounted on a rugged, portable skid made of a fabricated carbon steel base with 304 stainless steel wetted parts.

Solid bowl decanter type centrifuges often will dewater materials which are too fine for effective dewatering by filtering centrifuges.

In decanter-type units, extraction of liquid takes place in the cylindrical part of the bowl. Dewatering of solids by compression of the cake takes place in the conical part of the bowl. Bowl geometry must be adapted to achieve optimum results for the desired application.

The solid bowl decanter centrifuge consists of two horizontal concentric rotating elements contained in a stationary casing. The outer rotating bowl element is tapered so that the solids discharge from a smaller radius than the liquor. The inner element is a hollow hub screw conveyor with blade tips shaped to fit closely to the contour of the bowl. Feed slurry is introduced into the conveyor hub. The feed accelerates to the machine speed the slurry is delivered by centrifugal force into the rotating bowl by way of ports in the conveyor hub. The solids settle through the liquor pool formed on the wall of the bowl. The solids are then conveyed, due to a slight differential between the screw and bowl, up the drying beach to the solids discharge ports. The clarified liquors are discharge in the opposite direction from adjustable overflow ports.

For a longer lifetime and reliable performance, suitable and on time operation and maintenance on decanter unit is essential. Below instruction from work top cantrifuge manufacturer- GN Solids Control
