Tank Bottom Oil Sludge Treatment Equipment for Guangdong Client
Tank bottom oil sludge is a kind of waste mixture of oil, water and sand. However, if the oil and water could be recovered from the sludge, a great benefit would be obtained. This week, GN will finish the factory trail assembling and test for one set of oil sludge treatment system for an oil storage tank bottom cleaning project.
Working Principle of GN Oil Sludge Treatment System
GN oil sludge treatment system is using a series of equipment to separate the oil, water and solid step by step; while in each specific procedure, the separation equipment will be different.
Brief introduction on each module of Tank Bottom Oil Sludge Treatment System.
1. Coarse shaker – a shaker unit is used as the first step separation equipment to remove the coarse solid in the oil sludge. GN uses the linear motion shaker with 2 vibrators to provide an adjustable G force. The hot water spraying tube could be installed on the shaker for better washing of the solids.
2. Decanter centrifuge – the decanter is installed after the shaker unit for fine solids separation. Slurry treated by shaker contains lot of fine solids that need to be separated out under a higher G force. The decanter is an ideal equipment to do this job.
3. Inclined plate clarifier – even the decanter centrifuge cannot 100% remove the ultrafine solids in the slurry. GN puts one inclined plate clarifier to collect the slurry discharged from the decanter centrifuge. Multi-plates inside the clarifier will speed up the ultrafine solid sedimentation to the bottom of the clarifier, in the meanwhile, oil and water mixture will overflow to the OWS.
4. Oil water separator – OWS is the last procedure of the separation, here the demulsified oil and water will be separated and guided to different vessel for storage.
GN tank bottom oil sludge treatment system could also be equipped with dosing system module to make chemical solution that will be injected into the oil sludge for better demulsification performance.
