GN in India Oil Gas Exhibtion PetroTech 2019

GN Solids Control participated the PetroTech 2019 in India two weeks ago,many customers who have dealt with GN came to GN booth to talk about the order in process and future requirements. Some other visitors who came to GN booth and showed great interesting in GN technology and discussed with GN sales team for opportunity of cooperation.

GN showed below equipment and parts at the exhibition.

1. GNZS752 shale shaker is with two panel shaker screens. The shaker is the first stage solids control equipment for coarse cuttings removing from drilling fluids. GN is also able to manufacture the shale shaker with 3-panel and 4-panel shaker screen with larger treating capacity.

2. Shaker screen is now one of GN main products due to it is a consumable parts for mud recycling. GN set up own factory for fabrication of screen for better quality control and cost saving so that to provide customer with reliable and cost competitive products. GN is able to supply replacement screens for almost all popular brand shakers.

3. GN new developed solid vacuum pump is especially for high solid content sludge transferring with fully pneumatic driving system for safety operation in hazardous area.

Rather than the phisical equipment, the R&D work GN have done, and the plan of how to proceed further interested lots of people too, Many visitors showed interesting at GN oil sludge treatment system that can be used to treat the oily sludge coming from drilling waste, refinery plant waste and oil storage tank bottom remaining. GN makes the oil sludge treatment system modularized with premixing skid, coarse solids separation skid, fine solids separation skid and 3-Phase separation skid for valuable oil recycling and waste discharge reducing. Visitors stop by GN booth and watched the oil sludge treatment system working video.

Meet with GN @E2168 in Mar 27~29 2019 in Beijing CIPPE

A memo below to find GN.Show Time: March 27-29, 2019Show Location: New China International Exhibition Center, Beijing (No.88, Yuxiang Road, Tianzhu, Shunyi District, Beijing) GN Booth: E2168 (Hall E2)

GN is going to show below equipment for 3 of GN production line.1. Drilling Mud Solids Control Equipment2. Transferring and Conveying Equipment3. Oil Sludge Treatment System

Drilling mud solids control or we can say drilling mud recycling equipment is the largest and most important production line of GN Solids Control. GN will show the full 4 stage mud separation equipment including shale shaker, mud cleaner (desander & desilter), decanter centrifuge to make customer clear how the cutting is removed from the drilling fluids. GN self-made shale shaker screens would also be shown. So far, GN is the only one China shaker screen manufacturer whose screen is tested and complies with the API RP 13C standard in full API number. GN composite frame shale shaker screen now is accepted and approved by more and more users.

Oil sludge treatment system is GN new developed technology to recover the valuable oil and water from waste oil sludge. The basic working principle is to heat-washing the sludge with chemicals to take off the oil from solids, and then use separators to separate oil, water and solids. GN modularized the oil sludge treatment system into premixing, coarse solids separation, fine solids separation and different phases separation. In the past year of 2018, GN did shipped out several unit oil sludge treatment system, for more information, please no hesitate to contact with GN.

The Chinese New Year, and a New Goal

Techniqually after 4 Feb., Chinese start a new year 2019, by lunar clender. Though more and more young generation is enjoying the New Year from Januarary. It is still the most important day for every one to go back home for a family reunion. Kind of most important thing, so it does not matter then where ever you are or you will go after this day, to chase your dream, or a dreamed life, in that moment, you belongs to one place, where comforts you in your hard moments.In GN, also many people from far away, gathered here for a dream, attracted by something changes the world,changes the perceptions of bad name of made-in-china. So every year, we have 2 weeks off, and actually after 2weeks, everything start get back to track.

Well great news is:In 2018, It’s a wonderful year for GN. Its revenue in 2018 is 30% higher than that in 2017. Moreover, This achievement was accomplished under three adverse conditions.

    Firstly, the overall international economic form is depressed, and the national economic growth rate has declined sharply.    Secondly, the state's environmental protection policy is extremely strict, and the cost of products increases greatly, which leads to the rise of export prices and the decline of competitiveness.    In addition, for one of the main markets, the US market is also affected by the Sino-US trade war, which makes the export of American products impose a 25% tariff and reduces the competitiveness of GN products in the US market.

And in the new year, plan have been explained by chief Tom Zhou, as 3 H.The first H is Health. In order to provide a healthy working environment for company employees. The company invested about 1.5 million Dollars to build environmental protection production systems in new factories. In the new plant, the company will build a paint production line and a powder coating production line, and equipped with the most advanced VOC purification system. So that the VOC emissions can reach the national standard of 50mg/cubic meter. In addition, for welding and cutting fume, a fume treatment system is also equipped to make welding fume up to the national standard of 4mg/cubic meter. These environmental protection systems not only provide a healthy working environment for company employees, but also assume corporate social responsibility for national environmental protection governance.

The second H is Happiness. The company is committed to support employees to work efficiently and happily. To this end, in software, the company invested more than USD200,000 for online cloud-based ERP system, to achieve boring and repetitive digital statistics and process control through large data and cloud computing. In terms of hardware, the company plans to invest more than 2 million dollars to introduce 12 sets of welding robot workstations. Together with the original CNC processing equipment, paint production and CNC cutting equipment, these will make the production steps of the main processes of the whole company to be in the initial stage of intelligent manufacturing. And the labor intensity of employees is greatly reduced.

The third H is Honor. GN has now provided services to customers in more than 70 countries around the world, we are striving to make our customers break through 100 countries in another three years; Moreover, many of our products have reached the advanced level of our international counterparts, and some of our products are even in the leading position in the world. We will continue to strive to make GN brand comparable to the international first-line brand. Not only should we strive to do a good job in product brand, but also the new factory of GN Solids will provide better living conditions for employees. We will build more than 6,000 square meters of activity venue, so that everyone can live a richer life after work. Through the development of GN Company, we can improve the quality of life of employees, make GN employees proud of GN brand and work together to make GN Company become a “Huawei Brand” in solid control industry.

Stay tune with GN, and welcome join us, or join as a GN equipment user, as your proud of making this choice is always our goal.

Solids Control Equipment Ready for Delivery to India

Before Chinese New Year, before the coming Indian exhibition, now closing off the projects, as usual, though it is a quite busy ending of this year.

The decanter centrifuge and shale shaker are two of critical equipment in the drilling mud recycling system. The shaker removes the coarse cuttings by screen with different mesh size and the decanter separate the fine solids by centrifugal force.

Decanter centrifuge proved to be the best business driven since we moved to the new factory, which is specially for the innovative products, for us, like decanter centrifuge, shaker screens, now centrifugal pumps etc. Every year, got more and more business on decanter centrifuges, including the decanter centrifuges delivered with system, more than 200 units are exported all over the world.

For ultrafine solids, flocculants need to be added into the drilling mud to gather the solids so that the decanter centrifuge could remove that easily. GN also supplies thedosing systemwith tube screw conveyer for chemical powder transferring and blenders for chemical mixing. In consideration of the climate, GN can make the tank skid with roof for sunshade and rainproof.

GN shale shaker is widely used in oil and gas drilling and other type drilling projects. Normally for oil gas drilling, GN provided the shale shakers with explosion proof standard vibrators and control panel for safety purpose. GN has established close business relation with many clients from HDD industry in India. Application in trenchless drilling does not request explosion proof, thus client can choose the non-explosion proof vibrators for cost saving.

Welcome to visit GN yard, and also welcome to meet with us in all the exhibitions we may attend, or exhibit. Stay tune.

Aumina Slurry Dewatering Separation

Check the video:

So if you are not sure about your material, not sure about our equipment performance, we are enlarging our lab to be able to do more tests, in the coming new factory, GN is now building a big labratory. So in near future, more experimentation will be proceeded. Recently a client sent few tons alumina to GN factory, then we simulate the situation, then proceed with the centrifuge. Well end of the story is the client happy with the result, and purchased the centrifuges.

Well if it is hard to send us the sample, what should we do?

Send the sample to the closest lab, and ask them to find out the slurry properties, and something as below will be helpful then.


Or you can list all the info onto a table.


Centrifuge is not like other equipment, we use one place, then we can assure performance in all other places. Except you can confirm it is very similar application, like oil gas drilling, or you are doing hydro vac slurry treatment.
