Decanter centrifuge is one of GN main product that is used in many industries. This month, there are some decanter centrifuges in GN factory will be assembled completely and then shipped to Russia for a waste water treatment project there. The ordered is GN 14 inch drum diameter unit with model GNLW363C-VFD.GN Decanter Centrifuge Features
1. Top class material used for rotation part – GN 14 inch decanter centrifuge drum is using duplex stainless steel 2304 that is much better than SS316L. The centrifugal casting technology ensures the material distribution evenly so as to guarantee the excellent dynamic balance.
Recently, GN finished the fabrication of almost 60 unit mud agitators and several unit vacuum pumps for a domestic client.
GN mud agitator is flanged connection type with compact structure. It is cost competitive and mostly used in the mud recycling system for mud mixing. In the mud system, mud agitator is installed in mud tank with stirring function to prevent the solid particles settlement down to the tank bottom. Another function is mixing to accelerate the dissolution of the mud materials. The mud agitator is mainly consisting of motor, gearbox, stirring shaft and impeller.
Recently, GN finished the fabrication of one set oil based drilling cuttings treatment system for CNPC project. Before, CNPC has ever purchased several units drilling cuttings treatment system from GN Solids Control.
The drilling cuttings treatment system is used to treat the drilling cuttings discharged from primary solids control equipment like shale shaker, mud cleaner and barite recovery decanter centrifuge. For environment protection and cost saving consideration, the drilling operators is using the cuttings treatment system to recover more drilling fluids from cuttings, in the meanwhile, less waste will be discharged into the nature. To increase the working efficiency, GN released the vacuum pump unit that performs well to transfer cuttings sludge to treatment system.
Last week, GN shipped out one set high standard solids control system to Australia for a client from oil gas industry. Though the Australia standard is considered to be the strictest one in industry, GN was confident that the solids control system could be fabricated as per the standard and achieve client requirement.
Actually, GN ever shipped one sethelicopter lifting mud tank system to Australia client last year. That system was also high standard request on weight and tank design.
This week, GN arranged the delivery for one set hydrovac excavation waste slurry treatment system for a client from Canada. This is the third set same system sent to North America Territory. With many years development, GN equipment now could be used in many industries such as the normal drilling fluids solids control, waste cuttings management and this excavation waste slurry treatment project.
The hydrovac excavation waste is coming as a mixture of water, soil, large size trash and some other materials. 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.
