One More Set Solids Control Equipment for Russia Oil Company

Recently, GN just shipped out one more batch solids control equipment manufactured for a Russia oil company. Being a leading manufacturer of drilling mud solids control equipment, GN Solids Control is well remarked in world market for the excellent product quality and onsite performance. More and more drilling contractors and Oil Company came to GN for business negotiation.

The order from this Russia oil company is consisting of main solids control equipment such as shale shaker, mud cleaner, decanter centrifuge and the degasser unit. All equipment is painted customized color that is good for advertising to clients business.

Shale shaker is the first step separation equipment in solids control system. GN shaker is designed simply in the shaker screen installation and shaker deck angle adjusting device. Simple design makes the operators quickly to handle it. Patented sealing rubber installation method and high quality rubber material selection ensures the good sealing performance. Normally, in the same mud system, it is recommended to use same model shaker as the bottom drying shaker of the mud cleaner unit for convenient maintenance in future. GN mud cleaner is composed by the under shaker and movable cyclone manifold. The manifold frame is made with standard dimension and structure for easy assembling/disassembling in transportation or installation.

GN centrifugal degasser unit is with small footprint and installed vertically on mud tank, it can remove the cut-in gas from return drilling mud effectively so as to increase the working efficiency of subsequent centrifugal pump and cyclone unit. GN centrifugal degasser is a self-suction unit without extra feeding pump.

GN 14 inch decanter centrifuge is popular model in drilling mud separation system. The centrifugal casting technology makes the bowl material of the centrifuge denser to avoid the air bubbles so that to get a better dynamic balance. Normally, GN is providing the decanter centrifuge with explosion proof control cabinet, 6 meters feeding hose, solids discharge chute as standard package. For better installation on mud tank, GN always suggest client to choose the extra centrifuge supporting legs.

At the end of year 2018, GN successfully completed the shipment of this batch solids control equipment to guarantee the delivery on client site on time. Wish client a good operation of the project in using GN equipment, which is the best gift to GN in New Year.

HydroVac Slurry Separation Plant

GN Solids Control has been an expert for separation works, handled many different application projects, and lots of clients using GN equipment to separate the fluids/slurry they get from different source. One of the resources is hydrovac projects, packed into a vacuum truck, then transported to a plant, where many different equipment handling different it, and separate it out.

Hydro Excavation is a two part process and is a form of non-destructive digging or excavation and uses a jetting rod similar to your household gurney to spray high pressurised water at the surface in order to break it a part the dirt, grass, mud, clay or any compound surface. The second component is high volume suction vacuum to suck up the water and dirt broken apart from the first stage of the process. When you reach the place for discharge, then it is time for separation.

GN solution is to provide a classified-separation process to recover water and remedy the soil; the rough process diagram is consisting of following steps.

1. Waste Collecting and Washing Module – the waste slurry is delivered to site via the hydrocac truck and then discharged to a large size collecting hopper at which bottom there are valves to discharge the slurry onto a coarse screen for large size trash separation. The liquid with fine particles is collected in the tank located under the coarse screen. The liquid is then pumped to GN high G forcedrying shaker for finer solids separation. Here the operator can also use pressure flushing device to wash the slurry. GN shaker is fixed with composite frame shaker screen for longer working time and better performance.

2. Fine Solids Hydro cycling Separation Module – GN desilter with hydro cyclone manifold is fixed on a washing tank for further separation of the fine solids. The under shaker of the desilter is same model with GN drying shaker for easy maintenance. The hydrocyclone is using centrifugal force and gravity to separate the liquid and solids. The slurry is pumped into the cyclone with high speed for effectively separation process.

3.Dewatering Centrifuge Module – in this hydrovac excavation waste slurry treatment system, a 22 inch big bowl decanter centrifuge is used to remove the ultra-fine solids in the slurry. A chemical dosing system can be connected to the dewatering centrifuge to increase the efficiency of the separation.

Oil Sludge Treatment System for Kazakhstan Project

If the video is what you are looking for, pls check our website: http://gnsolidscontrol.com/video/oil-sludge-treatment-test-unit-working-video

This is a DEMO unit, which we firstly used in China, for testing, for showing client the principle, now actually more and more places need this DEMO, as we need to find out if this way works. The same unit now is in Hazakhstan, our client & partner there is doing some process, and use this to prepare, for the bigger unit. Idea is simple, separate solids out, then separate the liquid as required. Well, different site need different result. So then you possiblly will also need a TDU, thermal desorption unit, to make it finally so separate with each other, or vapour.

Skid mounted OST system is especiallydesigned for oily sludge treatment syste.

This user manual contains the technicalintroduction of each sub-section and detailed information on installation,operation and disassembly of the complete system.

This system separate the oily sludge byclassifications. This system is combined by vacuum pump module and pre-heatingmodule, the shale shaker module and centrifuge module, three phase separationmodule, oil tank, water tank and pipelines (electric control system andlighting system).

By means of multi-functional design, this OSTsystem is capable of treating oily sludge with different sludge proportions.

Then the client also now ready to a new bigger system, in this system, uses GNSP-40A Vacuum pump to suckoily sludge from sludge pit to pre-mixing (pre-heating) tank. Sludge is mixed,diluted and heated in pre-mixing tank, then transferred by a submersible slurrypump to GNZS752 shale shaker for the first step separation. Shale shakerseparates out large particles from sludge. A screw pump transfers sludge intodecanter centrifuge for second step separation. Solids phase from centrifugetreatment is discharged out of system, while mixture of oil and water istransferred to IPS (inclined plates separation unit)of three phase separationmodule. Most of fine particles settled onto IPS bottom and a few particles aretransferred alongside with oil and water to the disc stac for the finalseparation into oil, water and solids. Solids discharged by disc stac will becollected, while water and oil are discharged respectively to buffer water tankand buffer oil tank located in 40ft container. When ultra-sonic level meters ofwater buffer tank or oil buffer tank reaches a certain level, water pump/oilpump will be started, and oil and water are transferred respectively to largewater tank and oil tank for storage.

Another Set Solids Control Equipment to Russia

Guess if there will be only two equipment in the solids control system, what would they be? Shale shaker and decanter centrifuge. That is our main business also, after a while we now more focusing on offering equipment to our partners or tank manufacturers, as that will be more proper for lots of people. In anyway, it is getting less and less reasonable for transporting the empty tanks.

GN shale shaker could be used in drilling mudsolids control system as the primary shaker unit and also as the high G force drying shaker in waste cuttings management system.

Below features make GN shale shaker the reliable performance in using

1. Shaker vibrating deck is completely heat treatment for higher vibration G force

2. Shaker is installed with GN self-produced composite frameshaker screen with longer working time.

3. Patented rubber sealing installation method make the replacement of rubber strip much easier and better sealing performance.

It is just another set of solids control equipment to Russia, but also not quite, collecting feedback, improving details, or do small customisations, that is what we always do.

The decanter centrifuge shipped to Russia in this order is the popular 14 inch model with designed maximum speed up to 3900RPM. It could be control as fixed speed or variable frequency. 

Below features make GN decanter centrifuge excellent performance.

1. Bowl material is from duplex stainless steel 2305 with good machinability. 

2. Centrifugal casting technology makes the bowl material distribution evenly for a good dynamic balance. 

3. Tungsten material tile or bushing protection at abrasive part for longer working time and less maintenance. 

4. PLC control panel is available, and the sensors could be put on the centrifuge unit to monitor the status of the machine.

It is always tuff environment, no fancy, away from the crowd, being nowhere, and just do the work. That is where drill rig is, and that is where our solids control equipment is. Well it still make a lot of differences, can be in the desert, or the snowfield, far in the sea, or in the middle of some forest. Sometimes ship by road, sometimes by ship, and sometimes by helicopter.

Then in the desert, need to be strong enough for sunshine, high temperature; and in the snowfield, need to be tuff enough for the cold. That is what we do, a recent project, GN completed the fabrication of one batch solids control equipment for client from Uzbekistan. Now these equipment are in the final factory inspection and test running process, and then the equipment will be shipped out to work in the cold weather in Uzbekistan.https://lnkd.in/fTMBGVf hashtag#drilling hashtag#rig hashtag#separation hashtag#solidscontrol hashtag#mudsystem hashtag#tanks

Solids Control Equipment For Cold Site Low Ambient Temperature

It is always tuff environment, no fancy, away from the crowd, being nowhere, and just do the work. That is where drill rig is, and that is where our solids control equipment is. Well it still make a lot of differences, can be in the desert, or the snowfield, far in the sea, or in the middle of some forest. Sometimes ship by road, sometimes by ship, and sometimes by helicopter

Then in the desert, need to be strong enough for sunshine, high temperature; and in the snowfield, need to be tuff enough for the cold. That is what we do, a recent project, GN completed the fabrication of one batch solids control equipment for client from Uzbekistan. Now these equipment are in the final factory inspection and test running process, and then the equipment will be shipped out to work in the cold weather in Uzbekistan.

Shale shaker and mud cleaner unit are the first stage and second stage separation equipment in solids control system. It is know that the used drilling fluid is back from the down well with plenty of drilling cutting. The shale shaker is used to remove the coarse size cuttings in the drilling fluid. The subsequent equipment mud cleaner is to separate finer size cuttings. 

Shale shaker in the only type solids control equipment that to separate the cutting by size of the cuttings and opening on wire mesh screen. The mud cleaner is using centrifugal working principle to separate solid and liquid.

The ordered decanter centrifuge is GNLW363 with 14 inch drum diameter and typical working speed of 3200RPM, which is a very popular size in the market for drilling fluids recycling and waste cutting treatment in petroleum industry. The material of the drum is duplex stainless steel 2305 which has better machinability than SS316L. The protection by using tungsten alloy on scroll propeller and the solids discharge port give the equipment longer working life and less maintenance to bring more benefit to user.
