Leading manufacturers from China for high quality replacement screen

As the leading replacement screen manufacturer in the world, 2017 is a great year for GN Solids Control. GN Solids Control has done a great job through the year.

Firstly, GN Solids Control finished the upgrading of its screen production line, and also updating its high speed and big bowl decanter centrifuge products line. The updated workshops are equipped with the latest production machine and technology. And it is fully complied with the strict regulations for environment projects from Chinese government.

Secondly, GN developed and successfully launched its latest generation composite material shaker screen. Through 2017, GN composite material replacement screen covers nearly all the popular frame screens model. GN Solids Control own patent composite material replacement screens for Derrick shale shaker and mud cleaner are successful made out and sent to jobsites for performance test.

Furthermore, GN Solids Control got the API RP13C testing report for all its screen API Nos. from U.S lab. GN Solids Control is the only one Chinese screen manufacturer owns the testing report for screens.

GN Solids Control own patent pre-tension technology enables the replacement screens with longer lift time, better conductance, and bigger non-blank area. The better conductance and bigger non-blank area means a bigger mud flow with the same screen area.

GN Solids Control offers replacement composite material screens to below shale shaker and mud cleaner. But it is not only limited to below models:
1) Replacement Shaker Screen for MI-Swaco MONGOOSE PRO, MONGOOSE PT & MEERKAT, ALS, BEM, MD-3 series shale shaker or mud cleaner.
2) Replacement Shaker Screen for Derrick FLC 2000, FLC 500 , DP 600 and Hyperpool series shale shaker and mud cleaner.The screens are available in flat screen or pyramid screen. Composite screen is available for high quality and longer screen life.
3) Replacement Shaker Screen for NOV Brandt Cobra, King Cobra, Mini Cobra, Venom, LCM-2D, LCM-3D, VSM 300 series and D380/D285P shale shaker and mud cleaner.
4) Other replacement shaker screen for Fluid Systems 29×42, Kemtron/Elgin KPT series and other shale shaker manufacturer. Customized or OEM Shaker Screens are available.

How to feed cuttings to vertical cuttings dryer

Vertical cuttings dryer is typical processing equipment for drilling cuttings treatment, especially for oil based mud cuttings. It can reduce the oil content in the cuttings to 3 ~5%. In many counties, it is meet the standard for discharge. And the 3 ~ 5% oil on cuttings is easy for transport, and it is easy for next treatment, like thermal desorption unit.

Per different jobsite layout, and the diferent jobsite requirement, there are many ways to feeding the drill cuttings to the solidification unit.

Option 1: Screw conveyor

Auger screw conveyor is the most popular way to transfer drill cuttings to the vertical cuttings dryer, especially for onsite treatment system. Firstly, there will be screw conveyors to collection drill cuttings from solids control shale shaker, desander, desilter and mud cleaner. And then the second screw conveyor system will transfer cuttings to vertical cuttings dryer. After separation, the clean fluids recovered from solids control treatment equipment (decanter centrifuge excepted) will be feed to high speed decanter centrifuge to reduce the mud then, and then the recovered mud will be qualified for reuse again.
But if the drill cuttings is in the waste pit, or the liquid content is very high. Screw conveyor is not suitable.

Option 2: Vacuum transfer system

The vacuum transfer pump system has a wide applications. Vacuum transfer system can be used for nearly all applications. The Vacuum transfer system is a 100% air driven system. It can generate high vacuum pressure for long distance suction up to 50 m. The max. transfer length is up to 1000 m. And as there is no rotating parts in the pump. The vacuum transfer pump system allows for high solids content cuttings and big size cuttings up to 170mm. As the vacuum pressure is huge, while the vacuum transfer pump unit is used to feed for the vertical cuttings dryer, there should be some device, like cleancut, between vacuum pump system and vertical cuttings dryer.

Drill cuttings skips for the waste solids discharge

The drill cuttings skip is also called solids skips, waste collection containers, or skips. GN Solids Control can design and make drill cutting skips for the solids control system and drilling waste management systems.
Features of GN made drill cuttings skips (waste collection containers):

Customized waste collection container for SINOPEC

1) The drill cuttings skips are designed and fabracated accordance with DNV 2.7-1 standard. GN Solids Control can offer DNV 2.7-1 lifting certificate for the cuttings skips. The drill cuttings skips are capable for onshore and offshore applications.
2) The cuttings box is suitable for hazardous material transportation. The waste collection containers are completed sealed to avoid spill during transportation. And the cover is designed with an easy lock and unlock system for fast opening and closing. It is the ideal container to meet the HSE regulations for hazardous waste movement.
3) As manufacturers with his own research and development department, GN Solids Control can offer customized design drill cuttings skips to collect the drilling waste. The skips can be equipped with forklift access from all four sides, or only from 2 sides.
4) GN Solids Control designed and made drill cuttings skips (waste collection containers) suitable for container shipment. The waste collection containers can be put into container and loader with 2 layers. A full 40ft sea freight high container can load 14 ea waste material collection containers. The design can min. the sea freight cost, and also save clients inland shipping cost to move the waste collection containers.
Applications of the drill cuttings skips:
1) The drill cuttings skips can be used to collect and move the drill cuttings discharged from the drilling rig solids control system, like shale shaker, mud cleaner, desander, desilter and barite recovery decanter centrifuges.
2) The drill cuttings skips can be used to collect and move the cuttings discharged from the drilling waste management system, like high G drying shale shaker, vertical cuttings dryer, high speed decanter centrifuges,
3) slop oil, Oily sludge from tank cleaning, oily sludge from tank bottom, vessel, crude oil tank bottom sludge, etc…
