GN Solids Control makes full package oily sludge separation system for various types of oily sludge and oily waste. It can be used to treat oil sludge includes but not limited to oil sludge from Crude Oil tank cleaning sludge, oil sludge from Refinery plant waste oil sludge, and oil sludge from oil and gas drilling waste oil pit.
The most popular size Oil Sludge Treatment System made by GN Solids Control is GNOST-05 and GNOST-15. The related handling capacity is 5 m3/h and 15 m3/h. The handling capacity is specified by the decanter centrifuge and 3-phase tricanter centrifuge inside the separation system.
The principle of GN Solids Control Oil Sludge Treatment System is to use chemical to wash the oil sludge and with heating system to keep the temperature of internal materials 60 C degree to 70 C degree. The chemicals has maximum activities and can reach the best performance under the temperature 60 to 70 C degree.
After washing the oily slurry can be pumped to GN separation equipment to separate into oil, water and solids phase. The major separation equipment in GN oily separation system is shale shaker, decanter centrifuge and tricanter centrifuge. The shale shaker used in the oily sludge separation is a customized double deck shale shaker. There are jet nozzles around the the shaker deck for heating the oil sludge to keep it at a suitable temperate. On top of the double deck shale shaker, there are stainless steel anti-splash covers for protection the operators during system running.
The recovered water can be reused in the washing process inside the oil sludge separation system. After tricanter centrifuge separation, the BS&W inside recovered oil is with 2-3% (BS&W=Base Sediment & Waterin oil), it is clean enough for selling to the refinery companies. The discharged solids contain less than 2% oil which can be sent to biodegradation or thermal unit for final disposal if needed.
Clients need to note that, emulsified oil can only be treated after demulsification. If the oil sludge cannot be demulsified with demulsifier, the system cannot handle it.
