GN Oil Sludge Treatment System was High-profile at CIPPE 2018
Yesterday, the CIPPE 2018 exhibition closed successfully. GN attracted lots of visitors coming to GN booth to learn GN’s new releases. Being a manufacturer with lasting creation capacity, GN solids control has been bring new products to the show for many years. Every year, the new products take new business for GN, which is the critical factor of GN’s continuously improvement.
This year, GN showed the new developed compact skid mounted oily sludge treatment system at the show. This skid system actually is a compact three phase separation system for oil, water and solids. The processing procedure of the system includes premixing, 2-phase separation and 3-phase separation.
In premixing procedure, the oily sludge coming from the sludge pit is poured into the premixing tank. At the same time, the chemical of demulsification is added into the tank. The chemical dosing system is also one of GN main products that mainly used in dewatering system. Electrical heating line that equipped on the tank can heat the tank up to 70 to 80 Degree Celsius for better demulsification performance.
In 2-phase separation procedure, there are 2 main equipment, shale shaker and decanter centrifuge. The sludge in premixing tank would be transferred by a pipeline pump to a shaker unit for coarse solids separation. And then the liquid with fine solids will be pumped to the decanter centrifuge for fine solids separation. Large content of fine solids can be removed in this process, the liquid mixture is consisting of water, oil and little amount of solids will be collected in a buffering tank waiting for final 3-phase separation.
A disc centrifuge is the key equipment in 3-phase separation procedure. In this procedure, the oil remaining in the slurry would be recovered. This economic benefit of this system is to recover as much oil as possible in the sludge, for final discharged environment friendly liquid and solids, further treatment would be needed. And this system is pilot unit to prove the oily sludge can be treated via this technology, once the testing result was satisfying, GN is able to provide the system with larger capacity.
This time, GN also issued the vacuum pump that is an ideal machine for transferring high solids content and high gravity sludge. Full air operation makes this unit could be safely applied in hazardous area.
Other solids control equipment like high G force drying shaker, big bowl centrifuge, centrifugal pump, and replacement shaker screens are also shown at GN’s booth. Any question or request, please don’t hesitate to contact with GN.
