“GE, an industrial company, but also a digital company”. Some people may have watched this commercial on American’s main media, like CNN or NBC and we may wonder what does that mean? The answer is it represents the future trend-digital and automation.

As we all know, GE is the conglomerate in many industries, such as energy, electric appliances, aerospace and so on. So its action and strategy will represent the future of the industry. Recently GE just opened its new main office nearly San Jose and recruited a lot of engineers from Google, Apple, Microsoft with background of electrical engineer to develop its own system  called “Predix”, which is the world’s first and only cloud-based operating system for industry. GE plans to make “Preix” as the industry standard similar to the position of Microsoft Windows system in the PC industry. It will realize the digitalization and automation of the industry, including the oil and gas industry. One example for this trend is on June 14,2016, GE and Technip signed memorandum of understanding to explore digital solutions for new LNG projects. LNG will have great potential for growth as the world’s demand rises. So this prosperous area will be co-developed by the combination of strength of GE and Technip. GE will provide it reliable equipment solutions for the global LNG facilities, through sensors, advanced analytics and diagnostic expertise. Technip will provide unique expertise in EPC for LNG projects.


The future of the oil and gas industry will be more efficient and powerful, which will be realized by digital and automation and will optimize the equipment and operation to improve the productivity and cost-efficiencies.

As the crucial part of the mud cleaning system of the oil and gas industry, solid control system will also inevitably follow the trend of automation and digital, including its shale shaker, desander, desilter, mud cleaner, decanter centrifuge, mud agitator, cuttings dryer  and some other equipment and parts. GN solids control can manufacture the most advanced solid control equipment in the industry, such as the VFD controlled equipment which can realize the automation and digital.

Decanter centrifuges have been working as really essential equipment for separating ever since it came out yrs ago, it is widely used in many industrial sectors, including the food industry, substance industry, pharmacy industry in addition to oil and gas industries.
Divided from the types, the decanter centrifuges could be defined as horizontal decanter centrifuge and vertical decanter centrifuges. The working principles work the same way that by using the different centrifugal forces laid on the distinct size materials, a certain sort of particles are separated out there. In oil and gas industry, side to side decanter centrifuges are commonly utilized while they use Vertical Cuttings Dryers in front of the horizontal decanter centrifuges. GNLW series decanter centrifuges covers all needed sizes and applications useful for oil and gas drilling, such programs including following:
1 . GNLW452, 18 inch diameter involving bowl, big bowl centrifuge, middle speed. suitable for solids control application in gas and oil drilling, especially for barite recuperation. Barite is heavy and also expensive drilling material from the drilling liquid and could be fitted for re-use if it is very well recovered. This model of GNLW Centrifuge is normally fixed velocity as standard configuration, however it still has 3 optional rates by changing the pulleys and belts

2 . GNLW363, 14 inch diameter connected with bowl, most popular size throughout oil and gas drilling, high speed as much as 3900RPM, it provides the most programs among all GNLW centrifuge versions, in case of fixed speed GNLW363, GN designed 3 various speeds based on the experiences inside previous projects, and user could choose via employing different pulley and devices. In case of VFD controlled, GN also have 2 optional VFD control panel for selection, the speed could be set coming from 0 rpm to 3200 rpm.
3. GNLW453-VFD decanter centrifuge, 18 inch jar diameter big bowl centrifuge, with larger length size ratio as above mentioned GNLW452, higher speed and for extra excellent particles comparing with GNLW452, but with larger treating ability than GNLW363.
4. Major big bowl centrifuge GNLW553C-VFD with 22 inch pan diameter, which is no doubt a major guy in centrifuge family members, and GNLW223 decanter centrifuge with only 9 half inch bowl and a very high velocity, which is a baby member throughout GNLW centrifuge family.

 Vertical cutting dryeris sometimes referred to as secondary drying of cuttings.

Drilled cuttings with associated fluid from the rig solids-control equipment have been passed over a second drying shaker(usually High G shaker) for a number of years. The recovery of oil-based drilling fluid coupled with a 10-25% reduction in disposal volume is usually easily justified and has become standard procedure in areas where so-called pitless drilling or closed loop systems are the norm.

Generally, the secondary drying shaker is a four-panel screening (GNZS634 HI-G shale shaker) device running at 7.0-7.5g’s at the screen surface. Drilled cuttings from a drying shaker typically test between 8 and 12% base oil (NAF) by wet weight. This retention-on cuttings (ROC) figure is significantly higher than the current minimum allowed for offshore discharge in the United States and, increasingly, elsewhere around the world.

Accordingly, there has been increased interest in lowering the ROC figure by the use of different types of drying equipment.

GNCD930 Vertical Cutting Dryer is the latest design from World top solids control manufacturer – GN Solids Control. GN Solids Control is the first Chinese manufacturer for vertical cutting dryer. And also, GN Solids Control is the among the few companies who can complete drilling fluids solution with drilling waste management system.

As the first API certificated solids Control manufacturer, GN Solids Control will take a complete 500GPM hydraulic jack up mud system complete with drilling waste management for the world largest oil show– CIPPE in Beijing.

The latest design vertical cutting dryer will be took on the show. You can come and check GN equipments on GN booth.
