Vertical Cuttings Dryer 3
What’s GN vertical cuttings dryer working principal?
Vertical cuttings dryer can separate of solids and liquids by indicates of centrifugal force and collect the oil in the oil based drill cuttings or synthetic primarily based drilling fluids. The drilling cuttings is feed into the top hopper, by means of the screen basket and rotor, by the effect of centrifugal force, the fluids and fine solids pass through the screen mesh, and after that discharged through fluids output pipe and drop in to the mud tank, you will find 2 fluids output pipe, one particular of them is blocked along with the other one worked as fluids drain pipe. The significant solids or coal particles are retained around the screen basket and scraped down by the scrapper and pushed to the bottom of your screen basket and discharged through a solids trough. The discharged drill cuttings contained equal or less than 5% by weight, it really is dry enough to become shipped directly.
What is GN vertical cuttings dryer applications?
We use a vertical cuttings dryer system right after solids control system within the drilling waste management. A vertical cuttings dryer program firstly gather the cuttings separated from solids control system( shale shakers) by the screw conveyor, then fed into the vertical cuttings dryer, then the discharged the liquids is feed by nemo pump for the decanter centrifuge, the clean fluids is reused for make the drilling fluids once more. The drilling cuttings is drying and lessen oil in the drill cuttings.

Under the requirement of environmental regulation, vertical cutting dryer (vertical centrifuge ) is gained much attention from public. Cutting dryer is one kind of solution to deal with the oil based mud and synthetic base mud. Recently, GN Cutting dryer is also tested with water based mud which is widely recognized as  harder mud to separate solids without clogging. It is widely acknowledged that only high functional cutting dyer is able to deal with water based mud so GN cutting dryer is able to absolutely separator all kinds of mud

Compare to CSI Cutting Dryer, GN cutting dryer advantages

GN cutting dryer process water based mud

GN cutting dryer process water based mud

1.  GN vertical cutting dryer is install air knife and flushing system to prevent screen basket from plugging

2. Discharge screw conveyor is a good solution to transport the solids from the dryer to discharge site

3. Carefully select the material of flights and design the screen opening distance assure historically and consistently produced as low as 5% oil retention on cuttings by weight. GN  also provides parts and service for cuttings dryers.

GN also supports a plenty of solids control equipment to work with cutting dyer. GN not only provide the single device, but focus on offering a completely solution to your working site such as bored pile mud solution, diamond drilling mud recycling , dredging slurry separation, HDD(Horizontal Directional Drilling) and CBM

(Coal Bed Methane).  GN Solids Control will be your best partner in the solids control field.

GN Solids Control third generation vertical dryer is firstly showed in the CIPPE oil exhibition. vertical dryer is also called vertical centrifuge as it use the centrifugal force to deal with oil based mud and synthetic base mud. GN vertical cuttings dryer is able to reach drying efficiency OCC≤5° maximum dry the solids。

In order to meet increasingly strict environmental rules for fluids mud disposal and reduce the fluid cost. Many companies are seeking for the reliable and high performance of vertical cutting dryer. There are some advantages of our new vertical dryer showed below

New designs

New Genaration Vertical Cutting Dryer

New Genaration Vertical Cutting Dryer

1. Air knife is firstly installed the dryer which is consistently used for cleaning the screen during the work avoid the stick oil base mu
d block the screen. Precision design for angle and distance make sure air knife efficiently wipe out the sticky mud on the screen.

2. Cleaning pump will provide the high pressure water and vertical angle effectively to get rid of accumulated solids in the screen

3. Two auger are equipped on the bottom of the vertical cutting dryer to continually transport disposal solids to the site which is suitable for the handling a large amount of mud.

4. oil cooling and lubrication system ensure the long operation life and reliable motor performance.

GN also manufacture:shale shaker, mud cleaner, desander, desilter, decanter centrifugal, various pumps and all types of shaker screens

As one of the top Solids Control Equipments manufacturer in the world. GN offer a compelte line of solids control equipments and some drilling waste management equipments for the oil/gas industry.GN developed Vertical Cuttings Dryer has been proven to provide a dramatic reduction in drill solids waste discharge and to help reclaim the oil-based fluids or synthetic based fluids from cuttings.

Vertical Cuttings Dryer

Vertical Cuttings Dryer

The high-capacity GNCD930 Vertical Cuttings Dryer is a screen-type centrifuge which designed for the continuous feed and efficient throughput necessary for drilling operations.Convenient access to normal wear parts helps simplify maintenance and minimize unit downtime.

Setting Up Cuttings Dryer Operations

Successful Cuttings Dryer operations are not as simple as installing and running the cuttings drying equipment. The fluids recovered by the dryer usually contain high levels of low gravity solids that can cause significant problems if returned directly to the drilling fluid system. GN not only can offer Cuttings Dryer,But also Decanter Centrifuge, Screw Pump, Augor, Shale Shaker, etc.

The drilling waste management is one of the most important chanllenges in the oil/gas exploitation industry. The used drilling mud and cuttings are the main source of drilling waste.There are basically three types drilling mud. Oil-based mud, Waste-based mud,and synthetic based mud. OBM offer advantages over WBM for drilling operation. as a result, OBM are more frequently used in oil/gas drilling. As increased environment protection awareness and more stringent regulation on drilling waste discharge.The global drilling waste management market is therefore expected to grow to approximately $8 billion by 2018.

Currently there are four popular method of drilling waste treatment.

Vertical Cuttings Dryer

Vertical Cuttings Dryer

(1) Solidificatin and stabilization, If a polution is below the allowed limit,drilling waste can be solidified. Cement and silica the most popular agents.

2)Cuttings Re-injection. It is successful as well in onshore as in offshore operations. Only a very fine suspension can be injected. So the ball mill or the ultrasonic processor is often necessary to prepare proper particles for the suspension.

3)Thermal method is very useful for cleaning the cuttings.

4)Bioremediation is a more sustainable solution. it can be done in five ways: composting,bioreactors,vermiculture and landfarming.

GN as a top Solids Control Equipment manufacturer in the world. Now we also supply equipments for drilling waste management. The main equipments are Vertical Cuttings Dryer, Decanter Centrifuge, Screw Conveyor. etc. Vertical Cuttings Dryer mostly used for processing wet cuttings discharge from shale shakers to reduce oil content and return reclaimed drilling fluid to active system.

Two methods to transfer the OBM(Oil based mud)&WBM(Water based mud) cuttings ,depend on the layout and space of wellsite

1.Transfer the cuttings by screw converyer.,

Screw conveyer

Screw conveyer

2.Transfer the cuttings by vacuum transfer system.

Vacuum pump

Vacuum pump

How to choose your cutting transfer system in drilling waste management?

1.If the layout and space of wellsite is engough to install three screw conveyers,normally 36ft per length ,one section to hold the cuttings come out from the rig shaker ,one to transport it to the cutting dryer ,then one transfer to the truck. Transfer capacity 40-60 t/h

2.If the layout is compact and space is limited,the cuttings can be hold in a big cutting pit firstlt ,then use a vacuum transfer pump to suct them to a mud tank or trucked away at intervals 10t/h

Screw conveyer VS vacuum transfer pump in drilling waste management

Screw conveyer can work continiously to transfer the cuttings away immediately,no need to dig a big pit ,bigger transfer capacity,but make up for larger space

Vacuum transfer pump account for smaller space , trailer mounted and easy to operate .But the cuttings will be stored in the pit for a long time ,work at intervals,smaller transfer volume
