With one of the biggest contribution to our company business, Russian market is very active in the down time. With our partner Akros, GN have done a very good job.
In this exhibition, we share a same booth, brought equipment from local stock:
Shale shaker – the new developed shale shaker unit has been improved on the method to replacing the shaker screen. The ratchet wheel installed at both sides of the shaker deck makes the replacing of screens much easier than ever before by using a hammer to hardly push the block wedges. And ratchet wrench is a general tool that also be used in adjusting the degree of shaker deck.
Mud Cleaner – new type of mud cleaner only uses one buffering box for both mud inlet and cyclone discharging. Thus this mud cleaner unit could be used as both primary shaker and cyclone mud cleaner. The under located shaker unit is the same promoted model.
Decanter Centrifuge – in recent years, GN gradually developed a series decanter centrifuge for various industries. 9 inch for core diamond drilling, 14 inch, 18 inch and 22 inch mainly used in oil drilling mud recycling and oil waste management, and even the 30 inch model especially for large solids content liquid cleaning projects. GN’s centrifuge unit is well known for high processing technology and top class material application.
Centrifugal Degasser – this degasser is used to treat the gas cut-in drilling mud so that the keep a gravity of the mud, which will ensure the mud performance. Comparing with GN vacuum degasser, this type of centrifugal type degasser has a simpler working principle, small footprint and more energy saving, but it has full function to be a degasser.
GN Solids Control have been in waste management business from the time we spent R&D, resource & found to develop the vertical cuttings dryer, which also make us get through the bad time, when the oil price hit the floor. Now more and more countries are strict on environmental protection, though we have done a lot of things wrong, now we are going to fix it.
Oil sludge treatment, soil remediation is this kind of project, a capricious dump when the old projects are done, now more hassels need to be fixed. Oil dumps, waste mud, damaged soil etc. As a pioneer for waste management, GN have spent 2 years on TDU, thermal desorption unit research and development, now almost done.
The oil sludge treatment is more a system work, with shale shaker, decanter centrifuge, flocculant unit, heating tanks etc, to separate the solids into different phase.
As most of the oily sludge is a mixture of oil, water and soil, this oily sludge treatment is always a 3 phase separation process. Rather than a 3 phase decanter centrifuge, GN proposed a series modular equipment to do this 3 phase separation job with high efficiency. GN oily sludge treatment system has followed 3 main functions: solids and liquid separation, demulsion process and oil water separation. All the functions are realized within different tank and skid module.
Well this is not the whole system, it is part of it. This time in Uganda, a Chinese service company have packaged GN equipment, and now it is running.
With more and more experience, and upated equipment, GN will be able to supply better and better solution for the environmental protection.
The first mud recycling system was used for construction project in UK, it was designed as a mobile unit to the construction site, to save hassle of dirty mud. Normally that was one way to do it, another way is more often happend in Singapore, with a vacuum truck, the mud is transported to a certain place, and all the mud will be handled there.
This is sort of new business, as it happend because people now care more and more about the environment.
Lots of this kind of projects in other place also, such as Australi, and this time US. This client have their own exist mud system, to extend their business, they need one more system. The desin principle is mud similar as the one they already have.
For this one, shale shaker with a small tank as scalping unit, then the mud cleaner sitting in a bigger tank beside this unit, as next stage. After the desilter cleaning, the mud goes to the centrifuge, for better separation, whilst the polymer will be added, to help dosing the small particles. Then most of the solids bigger than 5micron can be separated.
Well normally the cut point of the shaker is 400 micron, the desander would be 75micron, desilter 25micron, decanter centrifuge is 2~5 micron. It is separated stage by stage.
A small dosing unit also included in this system, for chemical enhancing, GN have several different modular design, one is put all into a 20ft container, as dewatring container; then like this one, just keep it simple, a stand unit; also can put all chemical dosing, and centrifuge in one big container. Either way have the same purpose.
