Tank Bottom Oil Sludge Treatment Equipment for Guangdong Client

Tank bottom oil sludge is a kind of waste mixture of oil, water and sand. However, if the oil and water could be recovered from the sludge, a great benefit would be obtained. This week, GN will finish the factory trail assembling and test for one set of oil sludge treatment system for an oil storage tank bottom cleaning project. Working Principle of GN Oil Sludge Treatment System GN oil sludge treatment system is using a series of equipment to separate the oil, water and solid step by step; while in each specific procedure, the separation equipment will be different. Brief introduction on each module of Tank Bottom Oil Sludge Treatment System. 1. Coarse shaker – a shaker unit is used as the first step separation equipment to remove the coarse solid in the oil sludge. GN uses the linear motion shaker with 2 vibrators to provide an adjustable G force. The hot water spraying tube could be installed on the shaker for better washing of the solids. 2. Decanter centrifuge – the decanter is installed after the shaker unit for fine solids separation. Slurry treated by shaker contains lot of fine solids that need to be separated out under a higher G force. The decanter is an ideal equipment to do this job. 3. Inclined plate clarifier – even the decanter centrifuge cannot 100% remove the ultrafine solids in the slurry. GN puts one inclined plate clarifier to collect the slurry discharged from the decanter centrifuge. Multi-plates inside the clarifier will speed up the ultrafine solid sedimentation to the bottom of the clarifier, in the meanwhile, oil and water mixture will overflow to the OWS. 4. Oil water separator – OWS is the last procedure of the separation, here the demulsified oil and water will be separated and guided to different vessel for storage. GN tank bottom oil sludge treatment system could also be equipped with dosing system module to make chemical solution that will be injected into the oil sludge for better demulsification performance. For more information on GN oil sludge treatment system, please feel free to contact with GN Solids Control.

Two sets Hydrovac slurry separation system for America Client

If have to change the title a bit, it is 2 systems in operation, happy, then placed 4 more systems, now 2 system is ready, and 2 more will be ready soon. GN have done many projects on hydrovac slurry separation, some of the projects we only offer products, some we offer complete solution.  Hydrovac Excavation, or Non-Destructive Dig (NDD) is a bit different with other civil projects like HDD, Trenchless, or Pipe-Jacking etc. The process of Hydrovac Excavation is a non-destructive method using pressurized water (Hydro) and a vacuum system (Excavation) to dig. With this process, Wolverine Hydrovac makes a visual observation of existing buried underground utilities, pipes, or unknown infrastructures so that they may be avoided when digging in the ground. Then the whole process is also different, well the basic idea is same, spearate the particles stage by stage, from bigger rocks, to sands to silts. to clay. Do remember to check the definition of these particles. Anyway, typically here is the system:
  • Slurry Collection Hopper – this is a customized piece, for their application, if you have a better idea based on your site, and whatever circumentance,  you have the better layout for you, then do not mind telling us.
  • Coarse Screen Shaker  – One unit coarse shaker is installed under the collection hopper for coarse solids separation. Coarse shaker in installed on collection tank into where the slurry will drop waiting for further treatment. The submersible pump installed on the tank is used to transfer the slurry to subsequent module.
  • Fine Screen Shaker – the slurry treated by the coarse shaker will be pumped to fine screen shaker for small size sand separation, the shaker deck is covered with rubber to prevent the slurry spraying out to contaminate the equipment.
  • Dsilter Unit, similar as all the drilling mud separation systems, after the shale shaker, it comes to cyclones, and then it goes to 
  • Decanter centrifuge, during the operation, the client have helped us compare a lot in between USA decanters and GN decanters, and finally they chose to stay with GN for future projects.
  • Contact us if you have any further questions.

    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.
