3 Sets Solids Control Equipment to Europe


GN just finished the fabrication of a batch of solids control equipment for 3 sets oil rig. This order is for a Europe client, and soon later all the equipment would be shipped out. This order includes 3 types main solids control equipment, shale shaker, mud cleaner and decanter centrifuge. GN has upgraded the equipment design few times, below some features on the equipment will make clear why customer choose GN.


For clients far away from China, especially the drill rig manufacture, or packager, normally have the ability to design / manufacture the mud tanks, though it is not just a steel box, comparing other stuff in the whole rig system, it is not so complicate, it is not always economic comparing to high sea freight rate by bulk shipment, and the shipping time is not well scheduled.


Shale Shaker – the shale shaker in this order is used to be the primary shaker in the oil rig mud recycling system. It has 4 panels shaker screenwith each size of 585x1165mm, total screen area 2.7 square meters. At both sides of the shaker, bolted type shaker deck fixing design make it easy for avoiding the shaker deck vibration during transportation. The horizontal beams on both sides of the deck walls make the shaker deck much stronger to bear higher G force. Screen support frame is made of stainless steel for anti corrosion purpose. The embedded hollow rubber seals on screen frame perform a good sealing function and easy for replacement.


Mud Cleaner – GN suggests in the same mud system to use same model shaker as mud cleaner under drying shaker. It would be good for future maintenance and screen ordering from supplier. GN mud cleaner adopts full PU material hydro cyclone for long lifetime, and the cyclone manifold is removable easy transportation. All GN’s shaker has the installation points for quickly fixing the cyclone manifold.


Decanter Centrifuge– both of the bowl and screw is made of stainless steel, the bowl even SS2205 or SS2304, much better than SS316. On protection of the wet touching parts, GN use tungsten carbide tiles for screw and ceramic insert ring for solids discharge port. GN processes 3-stage balancing to maximize the balance of the centrifuge include 1800RPM low speed balancing and real operation high speed balancing as well as the assembly balancing.


Freely to get in touch with GN to find a balanced solution.

Hard Work, Happy Life

Not like a culture that we all been educated, it is a life, a family life, hard working with family members, and enjoy the life time, which you spent more than 1/3 of your life on. As my personal point of view, as a family is the highest recommendation on teamwork. Every year, GN will set up special fund for award of staff that made outstanding contribution to the company. In the year of 2016, GN marketing team worked hard and gained exciting achievement that the whole team was awarded a one-week tour to Thailand.

GN marketing team had a wonderful tour last week in Thailand. Everyone in the team enjoyed it. Some ones excited for their first time abroad travel, some ones were happy for feeling different culture and some ones were focusing on the amazing sightseeing.

Lots of people in the marketing team have worked together for a long time, and intend to make it even longer. Not only because we all share our dream, share our passion, share our respect on the name of GN, or GN products, but we do enjoy the time spending together.

Develop Together, Growth Together

Tom Zhou, the President of GN, said 'I wish all persons working in GN can get what they want here, like substantial income, position promotion and a happy life. I will try my best to make it happen. I wish in the same of company growing, all persons in GN will grow together.' Most people in the marketing team have been with GN more than 5 years. GN provided platform for them, thus they can show the talent there. They bring profit to GN, in the meanwhile, they realize their own value.

Drilling Waste Management System to South America

The 2 sets cuttings management system already shipped out last week. All 3 main cuttings management equipment are included in the system.

Vertical Cuttings Dryer – GNCD930 series cuttings dryer is designed with fixed speed of 900RPM to produce 750 G force for cuttings separation. This unit has an oil circulation system to protect the bearing during the rotating of the shaft. Furthermore, before running the oil pump for a while, around 1 minute, operator is not able to start the main motor. This is also a protection design. Drying shaker – GN’s drying shaker is now developed with a much wider shaker deck for easy collection of the cuttings. The new version drying shaker abandoned the hopper type buffer box by extending the shaker deck. This high G force drying shaker unit could be also used to treat the cutting discharged from solids control shaker and with fine mesh screen for treating the effluence from cuttings dryer for fine solids separation. Waste Decanter Centrifuge – GN has 14 inch, 18 inch and 22 inch centrifuge model could be used in the waste cutting management system. It is used to separate the solids with size of 2-5 microns in the drilling fluids. Drilling cuttings management equipment are used for further treatment of the drilling cutting discharged from the solids control primary shale shaker. By doing this process, more drilling fluids could be recovered. Environmental protection regulations request the driller to take the drilling cuttings management system into the drilling site. Modular design is an important idea for all the industry equipment, so do this for oil gas driling, and waste managment, after years of experience, GN have developed lot of modular design to help client have layout the site, or transport, or operate more effciently.

Soil Remediation Equipment Deliver to Site

With similar principle, soil remediation use similar equipment layout for the whole process. This time for the US client, they are using our modular design.

1. Premixing Module – In this module, a buffer tank is used collect the oily sludge, by adding water and chemicals, the sludge would be more flowable. In the same while, the demulsification processing is ongoing.

2. Hi G Shaker Module – The sludge is transferred via a sludge pump to the high G force shaker unit for coarse solid particles separation. The tank beneath the shaker unit is to collect the fluids with fine solids. The flocculation process will be done in this tank for gathering the fine solids to a bulk block for easy removing in the decanter centrifuge.

3. Dosing System Module – The dosing system was put in a 20 feet container. The 3-tank automatically dosing system could mix various chemicals accordingly different purposes. The chemicals used in premixing module and shaker tank are coming from this system.

4. 2 Phase Decanter Centrifuge Module – the centrifuge is ideal equipment used for liquid and solids separation. 2 products are coming out of the centrifuge: flocculated solids and water/oil mixture.

5. 3 Phase Separation Skid Module – The water/oil mixture from the centrifuge would be treated further here for oil recover and soil purification.

During these couple years, GN solids control gradually developed and released some new products that attracted many clients' attentions. One of the new products is the soil remediation system. As the name meaning, it is a system rather than individual equipment. From the date of releasing, many clients came to GN for learning more about this system. And at the beginning of this year, a client from The States placed order for their project on recovering the oil from oily sludge.

We also develop many different customized solutions for different clients.
