When corrosion happen on the decanter centrifuge.......

The purpose and the function of decanter centrifuge is to separate liquid our from solid and/or oil.  Some slurry which might contain materials that might cause the corrosion via contact with metal.  In the long-run of time, it will affects the work ability by decrease the performance  that lead less operation time.  When corrosion start to appear it and deal with timely matter, it can solve the problem without cause much of operation delay. 

By collective feedback on the operation field, corrosion can be spot-alike and evenly -formed.  The spot-alike or random pattern-like corrosion only happened on random area.  The evenly-formed corrosion is more serious issue that might leave the decanter centrifuge out of commission pre-maturely.  Random and spot-alike corrosion often happened due to the defects on the surface of metal.  The more serious and destructive elements that contain in the slurry flow into the decanter centrifuge and without after-work clean-up, it will slowly created the hole on the metal. If the decanter centrifuge is not for conservation, the corrosion action will become more and more serious.

Corrosive wear is a relatively common -happened corrosion. This kind of corrosion is not serious spot-alike corrosion, but in the centrifuge maintenance work, it needs to pay attention to.  This wear corrosion is due to friction parts in the work. When maintenance, the bearing can give parts contact daub lubricating oil, help to reduce friction, regularly will more serious wear parts are replaced, which can effectively prevent the corrosion wear.

GN Solids America LLC has a large warehouse get to 30, 000 sq. feet. GN Solids America helps to keep many decanter centrifuges are available in Houston. GN Solids America is providing rental services for these centrifuges and the some other solids control and drilling waste management systems. Different kinds are optional from varying speed to fix speed.

Drilling waste management system created by GN solids control

GN new developed a 2 function system for solids control and drilling waste management. The configuration is really as below:

1 two mud tanks, one for solids control, another frame for drill cuttings treatment, are both 40ft container and 20ft container size

2 solids control mud tank including shale shaker and desilter to split up the large solids collected in the offshore drilling rig.

3 cuttings moving system: we offer screw conveyor, cuttings collection hopper and Peristaltic pump to transfer the drill cuttings (from onshore drilling solids control system and also the first solids control tank) to vertical cuttings dryer.

4 drilling cuttings treatment system including vertical cuttings dryer, shale shaker and decanter centrifuge, feeding pump for shale shaker and decanter centrifuge, an entire skid to place these on the top for simple transportation.

5 frame of 20ft container size with thick felt cloth round the frame to help keep warm in cold temperature.

6 necessary pipelines, pathway, hands rails, man hole, cleaning gate and electric control system.

7 collection box for storage of cuttings, liquids

This technique does apply for drilling waste cuttings from both onshore and offshore, regardless of its treated by solids control system before or otherwise. And you can use it for cold temperature and temperature atmosphere.

The machine can as well be accustomed to clean the drill cuttings gathered for lengthy year’s operation within the mud pit/pool, but we have to analyze your oil based waste first of all by our engineer team. Thanks for visiting connection with GN solids control sales to obtain more particulars of the 2 function system and drawing.

When the drilling cuttings is collected only from onshore solids control system, we'll only suggest the drilling cuttings treatment system with vertical cuttings dryer and decanter centrifuge on a single skid, this will be our traditional design. The benefit of this technique is simple transportation, easy operation, and high end.

Verti G Cuttings Dryer’s simple Maintenance

Verti G cuttings dryer is specifically utilized in drilling liquids solids control system to recuperate the waste cuttings out of the primary shale shaker and mud cleaner. At the moment, the organization CSI is the world recognized most well-known manufacturer for that Verti G cuttings dryer unit. Regardless of on production and quality series, CSI is the No. 1.

GN Solids Control continues to be devoted to create and produce the Verti G cuttings dryer previously 3 years, and today GN second generation cuttings dryer happen to be examined effectively and already applied on-site. GN’s verti G dryer is workable for the water drilling mud and oil based mud making GN Solids Control occupy the very first seed in China solids control market. To guarantee the smooth performance from the verti G dryer, GN outfitted around the unit with flushing and coming system.

GN Verti G dryer flushing system

The verti G cuttings dryer of the flushing system is composed of the screw pump and relative hoses. Normally the material stepping into the Cuttings dryer could be dry and high viscosity. Using the rotating from the dryer bowl, the fine solids and liquid could be dispersed onto the interior encircled wall from the bowl and stick onto it. To wash within the cuttings dryer, the screw pump would feed water that is clean in to the bowl. Underneath the ruthless from the flushing water, the fine solids and dirty liquid could be flushed lower in the wall and obtain out of the dryer vessel.

GN Verti G Air Knife System

Certainly one of GN first generation Verti G cuttings dryer defects would be that the released solids from dryer unit isn't dry enough for simple transportation. The environment knife design could solve the issue from the block around the rotating screen opening. GN’s vertical cuttings dryer has 3 types screen for selection, the outlet is 250 microns, 350 microns and 500 microns. Under ruthless from the coming air, the blocked opening from the screen would open and also the solids could be blow to much dryer. This greatly improves the significant efficiency and helps make the transportation from the released solid super easy.

Aside from the verti G dryer, there'd be another essential equipment known as decanter centrifuge made by GN which may take away the much fine solid contaminants within the drilling mud.
