In oilfield drilling, there is a lot for different sludge including drilling waste, water, oil, and cuttings. This makes it to be a tought job to managing the liquid and solids separation. Especially getting enough drying solids from the mixture of drilling waste from mud sytem and tank cleaning waste.Now from GN lastest oifield application cases we have Vertical Cuttings Dryer for the tough job.
|In 2012 GN developped the first Generation Vertical Cuttings Dryer,As the first API certified company in China,After field testing and customer’s feedback, GN Solids Control now developed the second Generation Vertical Drilling Cuttings Dryer.GN second Generation Vertical Cuttings Dryer is used for OBM and SBM to get drying cuttings with oil below 5% even to 3%, and recovery oil for drilling fluids system.|
For getting oil on cuttings to below 3%, waste management company normally use the Thermal deporption unit (TDU)
Thermal desorption is an ex-situ treatment technology that utilizes heat to increase the volatility of contaminants such that they can be removed from a solid matrix: typically, soil, sludge, filter cake, or drill cuttings. Desorbers are designed as a separation technology to remove organic compounds from such matrices without thermally destroying them. The volatilized contaminants are then either collected or thermally destroyed in secondary treatment units. A thermal desorption system therefore has two major components; the desorber itself and the off-gas treatment system.
Usage for TDU in Drilling Sludge
Thermal desorption is a thermal soil remediation technique that has been utilized at several hundred environmental remediation projects world wide. As a mature technology, thermal soil remediation performance can be predicted with a high degree of confidence.
Besides ultilizing GN Vertical cuttings dryer, the high speed decanter centrifuge is very important for the LGS separation.
|As is known Vertical Cuttings Dryer is normally used for oil based drilling cuttings drying, because it is difficult for manufacturer to develop the water based drilling waste vertical cuttings dryer. So contractors normally use the High G Linear Motion Cuttings Dryer Shaker to handle the water based drilling waste. The problem is the linear motion shaker dryer can not give the expected drying cuttings.|
