GN Desanding Unit for Construction

except solids control system for gas and oil drilling, GN solids control also designs and manufactures mud recycling system for other sorts of drilling, for example horizontal directional drilling, CBM, Tunneling, geothermal power drilling and piling. GN Desanding Plant is really a special mud making clear system for mining, piling, and horizontal directional drilling created by GN based on clients’ needs. This technique includes a working capacity of 120m3/h. This technique is made to consist of 2 stages of solids control and clarification procedure. For any compact structure, this technique combines a shale shaker along with a desander right into a desander mud cleaner whose model is GNZY753E-Y1S. First level separation is as simple as a shale shaker, and 2nd level is as simple as a desander.

The dwelling of GN Desanding Plant is proven in Fig 1 to Fig3, including mud treating tank, GNZY753E-Y1S Desander mud cleaner, GNSB6×5A-12J Centrifugal Pump, light, electric control and ladder, handrail, pathway and pipeline. This drilling mud system has compact structure and rational layout, and it’s simple for installation & dissembles.

The underside deck from the double deck shale shaker with 25 mesh screens is perfect for first stage cleansing treatment. When mud transferred towards the bottom deck for process, the solids whose dimensions are bigger compared to holes on screens is going to be released out, while fluids will mix the screens then fall into the mud tank. Then, the mud is going to be shipped towards the cyclones with a sand pump for more solids removal. Solids from the desander cyclones will fall on top deck with 40 mesh screen after which be released out. The liquid is going to be released in to the arranging tank through overflow pipes. Floating ball will close the pipeline once the mud reaches enough high, then the drilling mud after processed will flow out of the discharge port.

Dredging Slurry Rapid Dewatering System for Water Solution

Many facilities are focusing on processing the contaminated water to make the water clean and also the removed solids safe for disposal. When mentioning the contaminated water, the polluted river and lake water along with the industrial water will always be concerned. How to find a good means to process water cost effectively can be the most critical problem the operator considering.

Here the dewatering system could be a perfect option. This rapid dewatering product is including several modules which individually functions various processing job. The idea of the operation is to discharge as find solids in the contaminated water as you possibly can, that will need various kinds of separation equipment.

For the beginning part to discharge the coarse debris and sand, the solids control equipment could be a great solution. It might need a coarse screen shaker which is often used to discharge, dry and stockpile bulky debris in the dredge slurry, for example rocks, shells, and cans. The underflow flowing through the screen could be pumped towards the desander unit for more treatment. The de-sanding unit uses the hydrocyclones to split up the sand by weight and size. Underneath the cyclones, the linear motion shale shaker is adjusted to handle coarse sand at anywhere and kind. The dried and stockpiles sand could be used again and moved. GN Solids Control is really a reliable supplier for that coarse shaker and de-sanding unit.

For that ultra fine solids still contented within the dredge slurry, it needs to be flocculated using the correct dose of polymer. Here require a feed tank to help keep a reserve of slurry that's continuously mixed by agitators. The slurry could be pumped towards the polymer system.

The rapid dewatering system could accomplish our prime speed dewatering, scalable and eco sustainable project for dredging slurry dewatering processing.

GN Decanter Centrifuge is applying within the offshore

As GN Solids Control keeps supplying excellent solids control and drilling waste management systems to worldwide clients, increasingly more GN devices for example shale shakers, desanders, desilters, mud cleansers, decanter centrifuges and vertical cuttings dryers etc.

Lately, GN supplied one decanter centrifuge for that American offshore drilling rig. As everyone knows, the drilling rigs that utilized on the offshore also have a strict requirement for the solids control devices. Once they looked for many producers who are able to manufacture decanter centrifuge, finally they chose GN decanter centrifuge due to the superb working performance, very long time usage without damaged and be assured service.

This offshore drilling rig is applying 2 sets centrifuges: Baker Hughes provided some decanter centrifuge on their behalf, so we provided another decanter centrifuge via our partner. Really, we've provided four sets decanter centrifuges and cuttings dryers to Baker Hughes in Russia, and working well under the cold temperature.

For that centrifuge we found here is one variable speed decanter centrifuge with VFD control panel. GN centrifuge and Baker Hughes centrifuge work together to complete solids separation work.

GN sent experienced engineers for service once the customer bought this centrifuge from us. Because of the significant working room is fairly small GN decanter centrifuge met some troubles on feeding drilling liquids. The pump is too far for the decanter centrifuge, and also the pump must feed drilling liquids right into a quite greater positive than normal. To create factor worse, the feeding pipe from the pump needs to go ahead and take working room into account, so many curves from the pipe that are either produced by the steel pipe or even the rubber pipe. It’s a bit hard to feed the centrifuge because of so many curves.

However, GN decanter centrifuge is working well in customer’s offshore worksite.

GN Vertical Cutting Dryer utilized in Russian Project

Hebei GN Solids Control Co., Ltd is the first API manufacturer of drilling waste management equipment and system in China. Inside a complete GN drilling waste management system, you will see 2 stages treating equipment. The first is vertical cutting dryer which is often used to dry the solids released (mainly waste cuttings) from shale shaker, desander, desilter or even the mud cleaner using the mixture of desander and desilter, and so the solids is going to be dry enough as needed through the environment rules to become disposed. The liquid is going to be delivered to the second stage treatment equipment: decanter centrifuge for more processing to split up ultra-fine solids out, and also the liquid is going to be collected or moved towards the active tank for recycling usage.

This past year, GN offered 4 group of drilling waste management system to Russia, and they will operate as planned even during the cold months with temperature below minus 20 levels. This type of system includes GNCD930 vertical cutting dryer because the first stage treatment equipment as pointed out within the first passage, and something GNLW363BG-VFD decanter centrifuge because the second stage dealing with equipment as referred to within the first paragraph. The liquid after decanter centrifuge is going to be shipped towards the recycling tank for recycling usage, and also the cuttings released in the vertical cutting dryer is going to be with 3%-5% oil content.

As everyone knows how large the part gas and oil play in Russian economy, though seriously shocked through the continuous lowing oil cost, Russia has the ability to feel the crisis. GN drilling waste management will begin operating as planned, and GN after-sales has done the commissioning to make certain scalping strategies can function normally and securely, also to make GN machine works best based on the drilling waste conditions.
