Mud Agitator for Offshore Drilling Project
Mud agitator play a important role in oil drilling industry for the drilling mud treatment. As we all know drilling mud is very important medium material, which can carry the drilling cutting from well, and balance the pressure between inside and outside well. However, drilling mud include lots solids, it keep the mud in a high density and high property. These solids are very easy to settle down on tank bottom. Mud agitator is one kind very efficiency equipment to blend mud.
Last week, we just delivered 12 agitators for offshore drilling platform. These agitator’s power is 15 kw with double layers impeller. When client install these agitator on tank, we suggest every 3 meters mount a agitator. Because the too long distance will reduce the mixing efficiency. When you select agitator , firstly need to consider the tank depth, when the depth is too high, we will recommend double layers or three layers even 4 layers agitator. The second factor is mud density, the high density also required the bigger power motor to provide driven force. The third factor is diameter of impeller, when the mud width is big, we also need to provide a longer impeller to make sure the impeller can blend the mud of edge. The number four factor need to consider the explosive standard, in different work area, which will require a different explosive proof standard ,most job site will require the equipment can be used in zone 1 application ,but on offshore drilling of ocean drilling platform ,Client normally need zone 1 application. GN can reach all these required.
The agitator actually have 2 structure, one is horizontal structure. The motor and shaft connected with right angle. The other structure is motor direct connect with reducer through flange, this structure can provide more higher efficiency transmission efficiency. And it demand less area.The cost of this kind agitator is higher the horizontal structure. However, it is getting more and more popular. If you have demand on mud agitator, welcome to contact GN.
GNOST-05B Oil Sludge Treatment Package System for Kazakstan Client
In oil gas industry, the oil sludge always the most tough thing for people to treatment. Oil sludge can not be naturally degradative and it can exist for many years with high pollution. Oil gas industry generated large oil sludge when drilling and oil storage. The oil basement drilling mud after treatment by solids control equipment, the drill cutting is one kind of oil sludge. All environment laws of different countries ruled that these kind sludge must be treated and not allowed to dump into nature environment. In other hand, oil sludge drilling mud also content drilling mud can be recycle for reuse, and as we all know drilling mud is very expensive. Whatever about the environment protection or reduce the drilling cost, the treatment of oil sludge is very necessary.
Different with drilling mud. Crude oil store always generate large sludge. Almost in all crude oil tank ,there will be settled lots of sludge on bottom. All we sure these sludge include lots valued crude oil can be recycle. For this kind oil sludge , GN developed oil sludge treatment system.
This system include chemical doing module ,thermal module, shake module, Decanter centrifuge module and also disc centrifuge module. As we all know, in low temperature, the oil is hard to separated off from solids. and we have to mixed with water to dilute the solids content, meantime wash the oil out from solids. In this case, higher temperature will be better for separation. Our thermal module can heat the sludge into 70 degree. After that we will mixed with emulsion to change the oil into some status that can be separate away with water. After that , slurry will be process be shake to remove out lot of solids, and then decanter centrifuge to remove fine solids. At last, feed into disc centrifuge to separate the water and oil away. In this system, we can get the very clean water and oil,
To different project, GN can provide several model with different treating capacity. You will be welcomed to contact us for more info.
GNLW Decanter Centrifuge for Drilling Mud Treatment
GN is one of the earliest China manufacturer that get into solids control industry and serve oil gas industry. With the 15 years development, GN get his reputation from user. Solids control equipment is what the best we do. GN has the whole series solids control equipment from primary separation to the end waste treatment. We can design and manufacturer the whole set solids control system. Today I will introduce the core equipment of solids control system GNLW-363 Decanter centrifuge.
As we all know shale shaker, mud cleaner both only can provide the big size particle in drilling mud. If client want to get cleaner mud, Decanter centrifuge is the best choice for further process of drilling mud. Actually the Decanter centrifuge application in drilling industry has been long history. The drilling mud after recycling time by time, the big particle can be move out by shale shaker. But with accumulation of tiny particle, the drilling mud property will be affected. Only the Decanter centrifuge can remove these tiny solids quickly. GNLW363 is specially designed for this application. Engineer considered all factors of drilling mud treatment when design this model centrifuge. Firstly, separation G Force, different with other industry requirement , the density of content particle in drilling mud is much higher than waters, so 2500 separation G force with 3500 rpm is enough for drilling mud treatment. In solids control system, the decanter centrifuge running is discontinuous, only when the tiny solids accumulate to a certain point, we run centrifuge. So 363 decanter centrifuge with 30m3 per hour treating capacity is suitable. If client required capacity is bigger, we can add one extra machine for use.
GNLW363 decanter centrifuge has fixed speed, VFD control and FHD. VFD and FHD are convenient to adjust centrifuge speed according to mud situation. And the flow rate of feeding pump is also adjusted by centrifuge box of decanter centrifuge.
We sold decanter centrifuge to more than 75 countries, if you need them, welcome to contact us.
