More Desanding Units to South East Asia

For piling, construction sites, the desanding unit is now being a must. Recently we have a few more units sent to South East Asia for pipejacking projects. For pipejacking, another type of tunnelling, to desand and reuse the mud, is now accepted by more and more contractors, the most common package is desanding unit and the decanter centrifuge. Well every project is different, and the requirement from local government varies, then different package been chosen and been used.

To choose system, it is easy to get some ideal option like from start to the end, each and every equipment is used on same flow rate, while in the actual project, it does not always work it that way. And sometimes it is not only depended on economy situations. The function of the decanter centrifuge is not always fully treat all the flow from the start, so it is not always needed to choose a huge decanter to work all out.

As GN Manufacture shale shakers, desanders, desilters, decanter centrifuges. So GN Solids Control is able to provide complete solutions for TBM slurry treatment project.The shale shaker for separation coarse solids, the desander for separation sands, the desilter for separation silts, the mechanical centrifuge for separation fine solids.The chemically enhanced technology with decanter centrifuge for separation ultra fine solids to discharge water.Been more and more experienced on desanding units and decanter centrifuge, we now understanding better and better about site design etc., feel free to contact us when you won the project.

Drilling Waste Management System to Xinjiang China

Drilling waste management system is now more and more often required come with the drill rig, nowadays, it is becoming to a standard package. Well more and more existing active rigs also looking to equip the package, to meet the environmental protection requirement. With more than two hundred decanter centrifuges deliver to the world, we also got more than 50 cuttings dryer sent out, some of them might go with the drilling waste management package. This time the client form Xinjiang province, purchased two system, for their drilling operations, quite standard design, a cuttings dryer, a decanter centrifuge, c/w feeding pumps, flushing pumps, intermediate tanks. And like always, it is on one skid.

GN have already expended our centrifuge production line, now more options, while for the waste management, solids control, staying the same design, just minor upgrades, you know, keep tuning. And we have delivered lots of similar systems to many sites, many countries, collected some feedback, so now this experience is aiding us on the drilling waste management package.

Though it is a mature system, we are still open in case is there any site got different conditions we did not expect. Freely to call or email us to talk about how you normally proceed the drilling waste, and how you want to improve, or just let us know your rig, mud pump, mud system, then we will hop into the drawing, and find a way to interact with all the other stuff.

2019 OTC,What You've Got About GN Solids Control

Met with a friend recently, he is not the one in the company who need to worry about selling, so when he check the show he is very surprised that how much people have been spending on the show, for the one time use stands, equipment transportation. Though you have to admit, that people they buy after they checked the equipment, but still a huge cost. Well beside the exhibiton holders are doing their own efforts to make the whole progress more environmental friendly, more reused staff; the exhibition is a good place to gather all the needed information, and it is a stage to show yourself.   OTC is this kind of stage, here all the related people come here to communicate, to check, to learn, to buy, to sell. Well as for GN, few things are very important: New Product, Popular Product, Solution Concepts.  

Shale Shaker, we know many shakers, many different names, from animals, snakes, and playing games about the food cycle, very glad we are not doing that. We are still showing a GNZS shale shaker, a linear motion, a simple shaker, no nick name. Well bit different shale shaker.  We know our client need a faster & easier way to handle the wedge, so they have it. And that is the first time we show it out to the world. Not a new technology, but GN is improving. Email us for more info.  

ViST Screen, this is a vacuum system, equiped with one panel screen, helping the shaker performance. To dry the solids at the last screen, and recycle more fluid.  It is suitable for all types drilling mud like OBM, WBM and SBM. In the meanwhile of recovery fluids, the drilling waste discharge is greatly reduced, and the cost in transporting the waste will be saved. With one set GN VIST vacuum shaker screen system on drilling site, the driller can fit finer screens on the shaker to separate much finer cuttings and save the cost in placing extra cuttings drying machine.  

From last year, shale shaker, decante centrifuge have been the most popular products, especially modle GNZS703, GNLW363, which we also have stock in Houston. The solids pump have been surprisingly popular, and been used in many new applications.   Oily sludge separation, since have to cover the ass, lots of oily pits need to be treated now, and that is exactly where you need our OST (oil sludge treatment) system. GN have developed many different modular solutions for this application, and been doing test, collecting data for different type, let us know if you need any help on this.

New Solution Release: Tank Cleaning System

After we have the inclined clarifier for oily sludge treatment, for the TDU, then we start to investigate how to use it in wider applications, then we realized, for similar products, many clarifiers have been used for many different applications. After doing some research, we improved our old tank cleaning system.   The GNTC-30C Tank Cleaning system supply fresh water to the high pressure tank cleaning machine mounted inside the tank. And  the integrated pumps will bring the dirty wash water back to the system for cleaning and return clean water back to the tank cleaning machine to reuse. This process will minimize the consumption of water and manpower involved. For this system, the main equipment would be the IPC.  GN Inclined Plate Clarifiers (IPC)is a high performance, Lamella plate design for removal of settleable solids in a variety of waste streams. The lamella plate is made from stainless steel.   The principle is simple, it is Stoke's Law, and if possible, we would suggest you to forget the formula, and just remember the Removal Efficiency Depends on Several Factors The final Fall Velocity depends on: (p - po)    = Density difference between particle and water n        = viscosity of water g        = gravitational acceleration constant d        = diameter of the particle   We have just finished the first unit, and also test it in our factory, with chemical, real mud, and video is here FYI. Also got another 2 system under production, so if you are interested in, pls come and check by yourself.

If You Missed GN in IE Expo China Shanghai Exhibition

GN is now having two brands: GN Separation & GN Solids Control, if you missed the IE Expo, you missed GN Separation first show. Well let us have a look, the new brand focusing on pumps, conveyors, named conveying; and various of decanter centrifuges, named separation.    That is also what we mainly showed here in the exhibition, the vacuum pump, and decanter centrifuges. GN Vacuum pump is a totally air driven pump that could be used to transfer liquid, sludge, powder and even dry solids. So long as the material is not in a hardened shape, it can be transferred by this vacuum pump. It is widely used in sewage sludge, wastewater and kitchen waste transferring. The decanter centrifuge is capable of working continuously and with small footprint.  GN got more than 10 years' experience in manufacturing the decanter centrifuge. In choosing the material of the centrifuge bowl and screw propeller, GN fully considers the fabrication availability and pneumatic balance.   Well if you are interested in some of these stuff, freely get in touch with GN sales team.   Where to meet then?  
  • First thing first, welcome to visit our factory here close to Beijing
  • USA Houston, we have office. And also the coming OTC show.
  • Abu Dahbi, yes, we will join that show. 
  • And Malaysia, Australia, more to come.
  • Too busy? Invite your contacts to your office, we will be more than happy to be helpful on your projects.
