This week, a full package of compact oily sludge separation system was finished from GN factory in Beijing China. The compact design fast movable oily sludge treatment system is purchased by a reputable Environmental Solutions Company from China domestic market.

There are 3-stage separation equipment included in the oily sludge treatment system.

1) There is a 2-panel small footprint shale shaker equipped in the system for coarse solids separation. The model is GNZS752. As mostly, the oily waste come out from different sources and it is mixture of different wastes. There may be big size solids in side. The big sides solids may block or even broken the centrifuges. The small size shale shaker is used to remove the possible big size solids in the sludge.

2) There are 2 centrifuges in the oily sludge treatment system. The first centrifuge we call it decanter centrifuge. The decanter centrifuge model is GNLW224, it is a 2-phase separation centrifuge. The 2-phase decanter centrifuge is help to remove solids or soil from liquid mixture. The 9 inch centrifuge is a min size decanter centrifuge. The bowl diameter is only 9 inch, but the bowl length and diameter ration is up to 4. The longer ration can help to get cleaner liquid. It is the smallest centrifuge from GN Solids Control for industry separation.

3) The second centrifuge inside the oily sludge treatment system is disc centrifuge. It is also called 3-phase centrifuge. As the name mean, the disc centrifuge can separation oil, water and soil.

Many people may wonder: in case the disc centrifuge can separate and get oil, water and soil. While you add 2-phase decanter centrifuge inside the system? Really, the 2-phase decanter centrifuge is surely not to increase the cost. The disc centrifuge can only allow liquid mixture with liquid content less than 3%. Otherwise, it will damage the centrifuge. While the decanter centrifuge can allow liquid with solids content up to 15% ~ 20%. Decanter centrifuge is a necessary as pre-separation before disc centrifuge.

GN Solids Control was firstly known as a manufacturer of drilling fluids recycling equipment that are used to remove the solids in the drilling fluids, thus the drilling fluids could be reused. In China, there are several this kinds of manufacturers who can fabricate the traditional solids control equipment like shale shaker, mud cleaner, agitator and mud tanks.
Keeping improving is one of GN’s features. In the past few years, GN has invested a lot on upgrading the traditional solids control equipment to make it easier for operation. Moreover, GN has developed many new products that keep GN a leader in the solids control industry. In the year of 2016, GN released the system for hydrocarbon recovery. It is an effective solution to treat the waste oily sludge.

Oil-sludge-Recovery-System

Oil Sludge Recovery

GN’s hydrocarbon recovery system is a three phase separation system. It includes primary coarse solids separation shaker package, fine solids separation centrifuge package and oil & water separation package.
The working principle of GN hydrocarbon recovery system is to remove the solid particles step by step from the oil sludge. The high G force drying shaker unit is equipment with hot water spraying system for better washing performance, this process will remove most of the oil content on the solids.
Decanter centrifuge is equipped with chemical dosing system for fine solids separation after demulsification process. GN’s dosing system could be used in all kinds of dewatering system for ultra fine solids separation.
The liquid discharged from the decanter centrifuge flows into the oil water separator package. Here an inclined plate clarifier is installed for further removing the remaining silt in the liquid for clarifying the oil and water mixer. Then the liquid mixer flows into the micro bubble separation for oil and water separating.
GN’s hydrocarbon recovery system makes GN a real separation solution provider other than a solids control equipment manufacturer. GN would like to communicate with all the clients on this hydrocarbon recovery system.

About microtunneling

Microtunnelling is a nature method of construction using pipe jacking. In many countries and areas, it also defined as a “Trenchless Construction Method”.

Slurry separation system for microtunneling

Microtunnelling project usually takes in urban district. In this case mud system matched for microtunneling request compact and a very small footprint recirculation slurry system with different capacity. This kind of mud system usually called as “slurry separation system”.

TBM Slurry Separation System In Oman

Features of slurry separation system

1) Steel Frame Screen with large open microns usually used.

As the solids usually bigger than oil and gas drilling, solids content higher and many bigger size sands / solids. And it is big diameter well with smaller depth, no higher request for mud quality. It is no need to separate very fine. And steel frame have a longer lifetime for microtunneling.

2) Compact system with smaller footprint: all separation equipment combined together, a storage tank and a mixing tank.

Usually, GN only offer separation plant and equipment for mixing part. And recommend users to build storage / mixing tank locally to save cost.

3) Big size hydro cyclones for large capacity. And it is not easy to be blocked.

As a drilling mud desander manufacturer, our desander and desilter machinery can be used in separating hydraulic mining slurry into different particle sizes.

Particle size separation machinery:

hydraulic slurry plant

hydraulic slurry plant

>0.7 mm solids – slurry shale shaker

>0.07mm solids – slurry 10’ desander

>25 microns solids – slurry 4’ desilter

>7 microns solids –slurry centrifuges

>5 microns solids- high speed decanter centrifuge.

Description of Hydraulic Mining Method: The Hillendale Mine hydraulic mining method consists of a series of water monitors which are used to direct a continuous high pressure (up to 40 bar at the Hillendale mine) water jet onto the face to undermine it, thus causing it to collapse. When sand from the face falls in blocks, the water is used to break up the material into a slurry which then gravitates into a satellite pump station situated at an elevation well below the lowest planned mining elevation.
