GN Screw Conveyor System for transporting drilling cuttings

With the enhancement of environmental consciousness. nowdays many more environmental regulations limiting or banning the discarge of various types of drilling fluids and associated drill cuttings globally.  The drilling contractors started to utilize "zero discharge" or "ship to shore" drilling operations.In these operations drill cuttings and associated waste fluids are collected on the rig in cutting boxes and then sent back to shore for disposal or treatment prior to disposal. even where the discharge of drill cuttings offshore is still allowed. there is often now a requirement to collect and transport drill cuttings on the rig for secondary process such as vertical cutting dryer that reduce the volume of drilling fluid associated with cuttings prior to discharge.

The screw conveyor is a simple way to transport drill cuttings which from shale shaker to a discharge port. It is achieved by the use of a scroll ( auger) which is rotated inside through by an electric motor. GN utilize a custom designed and constructed screw conveyor as part of drilling waste management system. The auger is designed with 12 feet per section which makes it to be standard spare parts for exchange with each other. The screw material utilized by GN is abrasive material which lasts longer than our competitors. The screw conveyor is designed to offer an efficient,low cost, cuttings transport system for offshore and onshore drilling installations. The screw conveyor are manufactured to the highest safety standards and are fitted with protective grating or cover to prevent foreign bodies entering the conveyor system, and to offer enhanced safety for all personnel.

This can handle a throughput of up to 528 gpm and is designed to remove particles down to 250 microns. 7.5G force linear motion GNZS703 Shale Shaker with big screen area(2.6㎡) especially using frame pyramid screen treating capacity increased which allows user to use big mesh size for fine solids, and decrease the solids content and reduce solids load for Mud cleaner.

Secondary and third cleaning of the returned mud using a GNPJ703-1N8S Mud Cleaner.

1# SB6x5-12J Centrifugal pump feed mud from 1# Shaker compartment to feed 10"x1 de-sander cones, where the particles larger than 45 microns are separated out by centrifugal force from desander cone nipple, and get down to GNZJ703-1N8S mud cleaner bottom shaker with a finer screen(150/200mesh) which again produces a virtually dry product. Major fluids with particle size less then 50microns go to 2# De-sander compartment. This is the 2nd phase solids control.
2# SB6x5-12J Centrifugal pump suck mud from 2# desander compartment and feed to 4"x8 desilter cones. Where the particles larger than 16 microns are separated out by centrifugal force from desilter cone nipple,and get down to GNZJ703-1N8S mud cleaner bottom shaker with a finer screen, which again produces a virtually dry product. Major fluids with particle size less than 16 microns go to 3# Mixing compartment. This is the 3rd phase solids control.

Integral mixing system using SLH150-35 Jet Mud mixer.

This system allows fresh mud to be prepared very rapidly from bentonite powder. The pump on tank end is dedicated to this function allowing continuous mixing or recirculation as required.

Integral charge pump to supply clean mud back to the drilling rig.

The mixing pump above is a dual function pump, on mixing pump outlet with a T pipe can be controlled by a valve to provide a continuous supply of clean mud from 3# mixing compartment under pressure to the high pressure mud pump, avoiding problems of starvation and cavitations which can rapidly cause damage.

 

GN Dredge slurry separation system operation

GN Solids Control is a professional solids control equipment manufacturer in China. Our business activities mainly on oil/gas drilling,HDD,TBM, dredging industry. GN's standard 1000GPM and 2000GPM dredge slurry separation system are specially designed for dredging industry.The system are consisted of shale shaker,desander,desilter, mud agitator,centrifugal pump,tank, They are designed to separates solids from dredged slurry via a three stage process down to 25 um.

How  the slurry separation system work

1,Entry:  The dredged slurry enters the system directly from the dredge.

2,Shaker: The slurry passes over shale shakers to remove larger particles , the slurry drops into a compartment of the tank where it is picked up by centrifugal pump

3,Desanding: The centrifugal pump pick up the slurry feed to desander,which removes the solids above the 75 Mircrons size. The overflow from these desander cyclones drops into a second compartment ,while the underflow is deposited onto vibrating screens for drying of the solilds

4,Desilting : The slurry which now has solids removed above 75 microns is picked up by centrifugal pump and pumped to desilter hydrocyclones to remove the solids  down to the 25 Mircrons. Again the overflow from the desilting hydrocyclones drops into the third compartment,while underflow is deposited onto vibrating screens for drying.

5, Discharge : The now " cleaned " fluid is picked up by  the centrifugal pump to be transported to a point designated by the client.

Factors influencing hydrocyclone performance

Hydrocyclone is a static device to separate particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. It is a closed vessel designed to convert incoming liquid velocity into rotary motion. It does this by directing inflow tangentially near the top of a vertical cylinder, This spins the entire contents of the cylinder,creating centrifugal force in the liquid. The Hydrocyclones are divided in two categories ( desanders and desilters )

The Cut point of 10 inch or 12 inch desanders is 40-45 um and that of 4 inch or 5 inch desilters 20-5 um. There are many factors influence the performance of hydrocyclone.  Main factors as follow.

1, Mud density
2, Solids Content of the underflow of the preceding equipment or Solids content of the mud that gets into the inlet of this unit
3, Mud Viscosity
4, Feed Pressure
5, Feed Flow rate
6, Apex size

In order to make the hydrocyclones to work efficiently. The solids Content of the drilling mud flows into the inlet of this unit must fit the unit itself. This requires the shale shaker separate the large size solids out as much as possible. if this conditions is satisfied. to make the hydrocyclones to work efficiently. adjustment of feed rate,feed pressure or replacement of an apex of another size must be taken. For more information about hydrocyclones. please feel free to contact with GN Solids Control.

GN Slurry Separation System for Solids Control in Microtunneling.

 Microtunneling (MT) can be described as a remotely controlled, guided pipe jacking process that provides continuous support to the excavation face. It can be used for installing conduits beneath roadways in a wide range of soil conditions, while maintaining close tolerances to line and grade from the drive shaft to the reception shaft. The Microtunneling process is a cyclic pipe jacking process. 

 There are two types of MT methods: slurry type and auger type. In the slurry type method, slurry is pumped to the face of the MTBM. Excavated materials mixed with slurry are transported to the driving shaft, and discharged at the soil separation unit above the ground. In an auger type method, excavated materials are transported by the auger in the casing, and directly discharged on the ground.However, the auger type MT is not popular these days. The slurry MT system is capable of handling wet, unstable ground conditions. The slurry MT system has five independent systems: one of the independent system is slurry separation system.
