The decanter centrifuge made by GN Solids Control

Decanter Centrifuge is the final stage equipment inside a complete solids control system. After being released from the desilter or perhaps a mud cleaner, drilling mud is going to be pumped into decanter centrifuge with a screw pump. A decanter centrifuge normally can separate solids having a diameter between two to seven microns out. Regarding a decanter centrifuge’s working principle, first of all I’d prefer to help remind you of the bottle that contains the mix of sand and water, you will find that sand is settled at the base, as the water is suspended onto it. That since the sand likes a greater sedimentation velocity compared to water because of its bigger density. Therefore we should make reference to a laundry-drier which is often used to dry cleaned clothes by centrifugal pressure, and the higher the centrifugal pressure is, the shorter time that it will take to dry clothes. Mix the 2 suggestions, you will be aware the way a decanter centrifuge works. GN’s decanter centrifuge having a mid-speed can remove solids of five to seven microns out, and GN’s high-speed decanter centrifuge can separate solids of two to five microns out. Besides to be the final equipment inside a solids control system, the decanter centrifuge made by GN Solids Control may also be used inside a drilling waste management system.

GN’s decanter centrifuge has got the following benefits and advantages.

First, because the first API licensed solids control company in China, GN solids control is also licensed by: Europe DNV CE, HSE, ISO9001, Russia TP&TC. And GN first of all built an USA based solid control company: GN Solids America.

Then, GN’s decanter centrifuge switches into many a brand new design. For instance, tungsten carbide tiles are fixed around the screw to safeguard it from put on, and also the tiles are simpler to become changed

Affirmatively, the decanter centrifuge made by GN will be your best option.

GN Has Inventory for Shale Shaker and Screen in Houston Warehouse

GN Solids America is one of the subsidiary company of GN Solids Control with location is Houston. GN is the first one manufacturer coming from China special for solids control equipment that has started their branch company in The States. GN has continuous inventory plan to make equipment stock available and prompt delivery.

Right now, GN Solids America has below inventory in Houston warehouse

4 units oilfield shale shaker — the shale shaker model stocked in GN Houston warehouse is the model of GNZS594E-HB. The features of this model are as follows: Simple structure with 4 panels shaker screen which is interchangeable with Mongoose original screen. That means the customers could by the shale shaker from GN and use both GN’s screen and original Mongoose screen on this shale shaker model. Or they could by GN’s screen and use on the original Mongoose shaker. The process for replace the screen is very easy, the patent design of the rubber sealing between the screen and deck make sure better performance of the sealing and long life time of the screen.

2 units mud cleaner which is using the under shaker of model GNZS594E-BH. With 2 pcs 10 inch desander cyclone and 12 pcs 4 inch desilter cyclones make from 100% polyurethane, the capacity of the mud cleaner is 1000GPM. The cyclone frame is removable, and then the under shaker could be used as a primary shale shaker.

Consider the user’s request on the shale shaker screen, GN also stocked shale shaker screen with full series API Nos. To some extent, shaker screen is the guarantee of the repeated orders and better after sales service.

Besides the shale shaker, mud cleaner and shaker screen, GN also has 14” centrifuge variable speed model in stock, and in the show room, there are also other equipment like centrifugal pump, screw pump and mud agitators.

You are welcomed to GN Houston warehouse for a look at GN’s equipment. At this time, GN also started the rental business for the shale shaker and decanter centrifuge. Welcome contact with GN for more information.

The Mud Gun’s Working Principle

Solids control service providers all over the world are common use the rectangular drilling fluid circulating tank for the reason that installation and migration performance of the system is very effective. At the same time, it doesn’t matter how good the mud agitator perform in excellent situation, the drilling fluid tank have the ability to corners that mud agitator’s propellers cannot reach and stir. In an effort to resolve this condition, install the mud gun in the top of the tank to agitate the far corner of the mud tank.

Mud gun functions as supportive machinery to the mud agitator. It comes along with nozzle that either made fixed angle or 360 degree ration angles the positive spray-effect distance of mug gun is approx. 3 meters long. The gun size is involved with drilling fluid density, viscosity and nozzle spray speed. Mud gun is mounted the top of the mud tank can be need adjusted as need whenever you want. The mud gun is connected with a motor-pump to stir the drilling mud and stop the solids from sinking on the base of the mud tank. The mud is mixed by being suck- withdraw into a pipe by a powerful pump and inject back into the mud tank by being pressured carry on the nozzle of the mud gun. The procedure is almost like how a jet sprays in the dish washer disposal.

Drilling mud is a wet mud like substance resembles like thick clay and is accustomed to retain the drill head in controlled-temperature and bear there mains of drilling cutting to the surface in water and oil and gas drilling operations. The mud is recycled and reused by passing it through several steps of filter and cleaning by screens of the shale shaker or mud cleaner and decanter centrifuge as it is circulated into the mud tanks then returning to the drill well on the drilling rig. So as to keep the mud as liquid-liked as they possibly can, a mud gun and mud agitator is utilized to keep the tank agitated and mixed. Drilling mud is made by mixing water and oil with a clay-like substance and also other chemicals.

Geothermal energy is thermal energy generated and stored in the Earth

Geothermal energy is thermal energy generated and stored in the Earth, means” earth’s heat”. GN solids controldesigned and manufactured mud recycling/ cleaning system can be used not only for oil & gas drilling, horizontal directional drilling, water welling drilling, diamond core drilling, rotery drilling, coal bed methane drilling , workover rig, but can be also used for geothermal well drilling.

They donot have much difference in drilling technology between geothermal well drilling and other energy drilling like oil & gas drilling, the important one is that the high temperature drilling fluids will damage the equipments, so you need a mud cooler to cool the drilling fluids. A mud cooler or a mud cooling system is an effective device to used for cooling the drilling mud in geothermal drilling or hot oil & gas drilling both in onshore and offshore.

GN mud recycling/ cleaning system for geothermal including the equipments below:

1 shale shaker: We adopt stainless steel shaker deck bottom which is Corrosion resistance, and the sealing rubbers on the shaker deck and under the shaker screens are also Corrosion resistance material.

2 hydrocyclones, we have 10inch hydrocyclones for desander and 4 inch hydrocyclones for desilter, the mud should go through mud cooler before feeding to the mud recycling system to avoid to shorter the service life of hydrocyclones and centrifugal pumps.

3 decanter centrifuge: GN solids control brand decanter centrifuge bowl assy is made of duplex stainless steel, and the other fluids touch parts are made of stainless steel 316L, which is Corrosion resistance and better strength.

GN solids control can design customized mud recycling system for geothermal project, with different treating capacity, wire height, mud tank size, qty and volume, what equipments to be used, etc.
