Leave a reply

GN Solids Control just developed one set of automatic Tank Cleaning System which can be used to treating the oil tank bottom sludge continuously. Now there have been several sets are used in the worksites.
GN Tank Cleaning System treating capacity is 30m3/h, it mainly includes the following two parts:
1. GN Surge Tank
GN Surge Tank stocks the water up to 7.5 m3/h. Water is pumped to the tank by one centrifugal pump, it’s used to clean the tank bottom under high pressure as those sludge need to be washed and diluted before feeding into the desilter cyclones.

gn-tank-clean-system
GN Cuttings Pump is used to feed into the desilter cyclones. There are 6 sets desilter cyclones assembled on the top of the tank. As we know, the desilter cyclones are take advantage of the gravity to separate out large solids in the sludge.
2. GN Slant Treating Equipment

gn-tank-cleaning-system-2
The after treated sludge is feed into the slant clarifier which is assembled with many pieces of stainless steel lamella plate. GN Slant Treating Equipment is especially designed to remove solids from waste slurry. Those lamella plates have the same angle of 55 degree with the horizontal line.
Water is discharged from the outlet on the upper part. While one set of screw conveyor is fixed on the triangle tank bottom, it’s used to transfer those thick particles.
GN Tank Treating Systems are easy maintenance and operating. As the main equipment in this system, GN Slant Treating is designed into a pretty compact structure which can be moved among different worksites as well.
GN Solids Control also provide dosing unit for better separation together with GN Tank System. Chemicals or flocculent can be added automatically before sending to GN treating equipment. All those flocculent systems can be put in one standard container for fast moving.

As the world most famous manufacturer, GN Solids Control is devoted to provide the best solids and liquid separation equipment and systems. GN Solids Control has been working on manufacturing and designing turnkey systems based on customers’ demands, most of GN treating systems are tailored to meet their needs.
Recently, GN Solids Control has provided some turnkey oil slurry treating systems to Europe and Africa. GN oil slurry treating systems are mainly used on treating thick oil slurry such as bottom oil tank slurry, refinery slurry etc. By using GN oil slurry system, solids, oil and water can be separated into different parts.
GN oil slurry treating plant is mainly including the following GN equipment:
1. GN Shaker Tank
By using one GN vacuum pump, the oil slurry can be transferred to the shaker tank. GN shale shaker separates the solids larger than 100 microns, coarse solids are collected by a catching tank below the shaker.
In order to keep the separated slurry from sediment, GN mud agitators are also fixed on the shaker tank and kept rotating.
2. GN Centrifuge Tank
The after treated slurry is added and mixed with different Acid or Alkali in order to have the proper value. Polymer and chemicals are added into the decanter centrifuge tank, so the finer solids can be separated out by GN decanter centrifuge.
In order to keep the thick slurry running well, GN shaker tank and GN centrifuge tank are also assembled with heating lines.
3. GN Slant Clarifer
GN slant clarifier is especially designed to separate small solids in the oil and water by gravity. Many pieces of slope metals are assembled inside to help separate. This is the first separation phase for oil and water.
4. Oil &Water Separator
GN oil and water and separator is used to separate oil and water separately. There is one oil surge tank and water surge tank fixed after the oil and water separator, they are used to feed the water and oil into the afterwards oil tank and water tank separately.

GN Dredging System to Separate Finer Solids

Leave a reply

GN Solids Control is leading solids and liquid separation manufacturer. GN whole product line includes shakers, desanders, desilters, decanter centrifuges and cuttings dryers. GN Solids Control provides standard treating system to meet customers urgent demands, while for those customers have special demands, GN Solids Control also provides customized solutions.
Recently, GN Solids Control has received many inquiries on the dredging slurry treating. In the past, GN Solids provided many slurry treating systems with shakers, desanders and desilters. As we know GN desilters are assembled with 4 inch cyclones, they can separate the solids larger than 25 microns. While some other customers have higher demands on the slurry particles, GN Solids Control recommends using decanter centrifuge with flocculent system.
Generally speaking, typical dredging slurry includes 5~20% solids, 0~70% coarse debris (usually larger then 6mm),10~100% sands (diameter is around 0.07~6mm) and finer particles like clays or silts or organics 0~100% (diameter is less than 0.07mm). In order to separate out those finer solids, GN centrifuge is a necessary choice.
Let’s take one GN 350GPM treating system as an example:
1. Double deck shaker
GN double deck shaker is using opening mesh screen on the top deck to separate the large materials out, while the bottom deck shaker is using common composite API shaker screens.
2. Desander
One GN 10 inch desander cyclone is used after the double deck shaker. Desander cyclone to separate the solids larger than 55 microns. One centrifugal pump is also fixed on the tank to feed the cyclone.
3. Flocculent System
GN flocculent system has a compact structure, all the devices are put in one 20ft standard container. Flocculent will be mixed thoroughly with the slurry separated from desander, those slurry is feed into the GN centrifuge by GN screw pump.
4. Decanter Centrifuge
Two sets GN decanter centrifuge GNLW453 are used for treating finer solids. As the flocculent system helps to collect all those finer solids and get larger, they will be easily separated out by GN centrifuge. Due to the increasing of the gravity, the solids percentage is getting bigger, so centrifuge actual working capacity is around 350GPM.

Shearing mixing hopper and jet Mud Mixing System for drilling mud system

Leave a reply

Jet mud mixing system is a normal and necessary part of most kind of drilling mud systems and liquid mud plant (LMP). It is used to prepare new mud and qualified mud, and service for drilling activities. The mud mixing system can be used to mix oil based mud (OBM), water based mud (WBM), as well as synthetic based mud (SBM).

Jet mud mixing system is actually a combination of mixing pump, mixing hopper and control panel. All of them connected by pipelines, they can be mounted on the tank separately per tank layout. They can also be mounted on the same skid as a complete unit.

The jet mixing hopper is also called shearing hopper. It can be mounted on different position of the mud cleaning system for different purpose.

Centrifugal pump is the most popular pump model for jet mud mixing system. Another pump model is shearing hopper. Clients can choose motor drive mixing pump, or diesel engine drive mixing pump, to meet for different demands.

Different position of jet mixing hopper for mixing system

1) The jet mixing hopper can be mounted on the top of the mud tank. Advantage of the tank top hopper is easy for mixing chemical as the gravity. But you should to consider lifting of the chemicals. Sometimes, it is even 1 ton big bag. you should consider the necessary device to help for the chemical lifting. Operation table and crane cradle is the popular way to service for it.

2) The normal way is to put the shearing mixing hopper on the tank skid, next to centrifugal mixing pump. The mixing performance may not as good as on the tank top, but also acceptable. And it is easier for the chemical lifting.

3) Another way for the shearing hopper is on a separate skid with centrifugal mixing pump and control system. The complete is in a separate skid. It is more flexible for application. Users is easy to more the mixing unit from one jobsite to another jobsite, or move it from one tank for another.
