The drilling waste cuttings treatment equipment is the key equipment in the closed loop mud recycling system. By applying the cuttings treatment equipment, more drilling fluids would be recovered to save the drilling cost on water or base oil consumption; and less drilling waste would be discharged for environment protection. 
This week, GN finished the fabrication of a batch decanter centrifuges and vertical cuttings dryers that would be shipped to Africa client who has ordered many unit centrifuges and cutting dryers from GN. During many years developing, GN’s equipment is well approved and accepted by more and more international high-end users.

In this order, all the decanter centrifuges and cuttings dryers are mounted on the telescopic skid, which will enable the going up and down of the equipment position per working conditions on site. With a high position, the treated cuttings and effluence liquid will be discharged out and flow to storage container easily. 
The performance of GN’s vertical cuttings dryer has been approved that the OOC of the discharged solids will be less than 5%. The screen inside the dryer unit has excellent features for blocking the solids cutting particles and releasing the liquid. It will bring high separation efficiency for cuttings and the OBM. The cuttings dryer unit is used to treat the cuttings discharged from the primary solids control equipment, all the cuttings would be collected and transferred to cuttings dryer. Currently, GN has developed an ideal vacuum pump that can transfer the sludge with solid content up to 80%. The pump is just the right device to transfer the drilling cuttings.

In the technical diagram, decanter centrifuge in located after the cuttings dryer unit to polish the liquid discharged from the dryer. The fine solids in the drilling fluids would be removed out by the decanter centrifuge, thus more drilling fluids would be recovered for reusing. GN has upgraded the centrifuge bowl material to SS2304 for batter material distribution and dynamic balance. The ordered centrifuges include both fixed speed model and VFD model for client’s different purpose.
The VFD control panel is equipped with AC device for high ambient temperature application. This ensures the continuously running without shut off caused by electric components temperature rising. 
GN nowadays is able to provide the complete solution on waste cuttings treatment. If any request, please no hesitate to contact with GN.

TRENCHLESS ASIA 2018 is the 10th event in this series and for the second time will be held in Kuala Lumpur. It is held every 2 years, and GN has attended it last time in 2016.

GN Solids Control is a professional manufacturer of mud recycling equipment and mud system used in trenchless drilling project. 
This year GN booth number is 26, welcome to GN’s booth to have to talk with GN’s team on more information about GN. Mr. George and Ms. Renee will be your contact at the show.

For the trenchless industry, GN has developed standard compact mud system with functions of mud recycling, mud storage and mud mixing. Per customers rig capacity, GN is able to provide mud system with different flow rate. For the primary mud recycling equipment like shale shaker mud cleaner and even decanter centrifuge, GN has different models for customer’s option.

GN’s self-contained mud system is including all stages of solids control equipment and mud tanks for customer’s high configuration requirement. For cost saving consideration, GN also has economic models to satisfy the customer. The compact de-sanding unit could be also used in piping and micro tunneling project.

This year, GN will show the new developed mobile vacuum slurry pump at TRENCHLESS AISA 2018. The pump could be widely used for high solid content and high gravity sludge transferring. It is an ideal solution for delivering the drilling cuttings discharged from the mud recycling system to the treating plant. 
GN is looking forward to seeing you there at the show.

GN solids control is getting more and more business from the environment protection industry other than drilling industry. The continuously improving makes GN’s products could be used in other projects out of drilling mud recycling and waste cuttings management. That is the reason GN will show at the IE expo China 2018 in Shanghai.
This show is for environmental protection, and GN will have a booth and display the self-manufactured equipment there. Please write down below information and come to GN’s booth to learn more on GN Solids Control.

Show Date: 3rd – 5th May
Show Location: Shanghai New International Expo Cernter
GN Booth: W2 566

The Equipment GN will display at the show are decanter centrifuge and sludge vacuum pump.

GN’s 2-phase decanter centrifuge is a kind of equipment used to separate the fine solid particles from liquid to clean the liquid. Before, GN’s decanter centrifuge is applied for removing the drilling cuttings from drilling fluids, thus to make the drilling fluids reusable. Due to same working principle, the decanter centrifuge is able to be used in waste water treatment project to separate the coarse solids in the waste water at early stage of the waste water treatment system. Sometimes, the flocculation agent would be added into the waste water to gather the ultrafine solids, and then feed to the decanter centrifuge for separation.

GN’s vacuum pump is used to a fully air operated pump that can transfer high solid content and high gravity sludge. In environmental protection, the pump can be used to transfer the sludge in waste pit to the treatment plant. It has high efficiency for suck from 50 meters far away and discharge to 500 to 1000 meters. The vacuum pump can even suck the sludge with solids content up to 80 percent or full dry material like sand, soil.

GN is looking forward to seeing you at the show.

In the past CIPPE show last week in Beijing, GN’s vacuum pump was awarded favorable comments by visitors coming to GN booth. Many visitors were amazed to the function of this pump; some contractors even told they finally find an ideal transferring solution. The vacuum pump is also named solids transfer pump that is a type pump operated by connecting the air supplying to suck and discharge high solids content material alternately.
The vacuum pump could be widely in tough environment for most of the liquid, wet sludge and even dry solids transferring. Below link would guide to the working video of this vacuum pump, please click for reference.

Main Application of Vacuum Pump
Waste drilling cutting transferring is one of main application of the vacuum pump. The drilling cutting discharged from primary shale shaker, cyclone unit and decanter centrifuge is with high solids content, which makes the cuttings difficult to be transferred to the cuttings dryer unit for further treatment. The vacuum pump can transfer the material with solids content larger than 80 percent. The high transferring efficiency prevents to collect the waste cutting firstly into a mud pit, which make the closed loop mud system a reality.
The oily sludge coming from refinery waste, crude oil tank bottom residual and barge vessel cleaning is still with large quantity oil remaining in it. To recover the oil in the sludge, firstly the operators need to transfer the sludge to the oil slurry treatment system. Air operation can firstly produce vacuum inside the pump to suck the sludge from 50 meters out there and the discharge under positive pressure to far away 500-1000 meters.
Besides, the vacuum pump can also be used in waste pit cleaning, frac tank and animal waste transferring. It is worthy to mention that the pump is fully air operation for hazardous area application. Due to none any rotating parts inside the cavity, the wearing is less for long working time.

GN’s mobile vacuum pump is installed on a wheel skid that makes the unit could be moved easily onsite. The handle is foldable for moving and operation convenience. GN has models with capacity of 10 cubic meters per hour and 20 cubic meters is on the wheel skid, the operation is automatically. For larger capacity, customer could choose the model of 40 cubic meters per hour for both automatically and manually operation available. GN got over ten orders on this type vacuum pump at the CIPPE show.
