GN now is gradually known as a separation solution provider who not only has the business to provide equipment for drilling cuttings separation from drilling fluids, but also for recovery the oil in the oily sludge. After couple years research, GN developed a 4 stages separation system that could effectively recover the oil from the oily sludge coming from oil based drilling waste, refineries waste and crude oil tank cleaning slurry.
To be frank, GN’s 4-stage oily sludge treatment system is consisting of 4 modules. These 4 modules could be combined freely as per different sludge conditions or outputs. Now let’s see what is the 4-stage oil sludge treatment system.
The first stage is the high G force drying shaker with washing tank. The high G force drying shaker is located on a slurry tank. With a hopper type feeder, the oily sludge could be fed to the shaker easily. Up to 8 G force could effectively remove the coarse material in the sludge. The shaker unit could be equipped with hot water spraying system for better demulsification. To prevent the oily sludge spraying out of the shaker deck, this shaker will have a top cover.
