GN Separation<\/u><\/a>\u00a0has recently completed the manufacturing and factory testing of a GNLW554-VFD D<\/u>ecanter centrifuge<\/u><\/a>, which is now ready for shipment to an oil industry customer in Africa.<\/p>\n

The centrifuge will be used to treat tank-bottom oily sludge, a challenging waste stream generated during the storage and handling of crude oil and petroleum products. By separating solids and liquid phases more efficiently, the equipment will help the customer recover valuable oil, reduce sludge volume, and improve the overall efficiency of oily sludge management.<\/p>\n

The GNLW554-VFD D<\/u>ecanter centrifuge<\/u><\/a>\u00a0is a 22-inch\u00a0model\u00a0designed for continuous solid-liquid separation. Unlike batch-type separation equipment that requires frequent shutdowns for cleaning, a decanter centrifuge continuously separates and conveys solids during operation.<\/p>\n

\"\"<\/a><\/p>\n

For oily sludge treatment, the feed is usually conditioned before entering the centrifuge. Depending on the sludge characteristics, processes such as dilution, heating, and chemical conditioning may be applied to improve separation performance.<\/p>\n

Inside the centrifuge, high centrifugal force separates the solid and liquid phases. The heavier solids settle against the bowl wall and are continuously transported by the screw conveyor toward the solids discharge outlets. The separated liquid phase is discharged separately for further treatment or oil recovery.<\/p>\n

The GNLW554-VFD is equipped with a variable frequency drive system, allowing the bowl speed and differential speed to be adjusted according to the characteristics of the feed material. This flexibility is particularly valuable in oily sludge applications, where sludge composition and properties can vary significantly from one project to another.<\/p>\n

Efficient separation is an important part of modern oily sludge treatment. By recovering oil from waste streams and reducing the volume of solids requiring final disposal, operators can reduce waste transportation and disposal costs while improving resource utilization. For oil producers, refineries, and environmental service companies, this can provide both environmental and economic benefits.<\/p>\n

GN Separation<\/u><\/a>\u00a0offers a range of equipment for oily sludge treatment, including pre-treatment systems, chemical dosing units, decanter centrifuges, three-phase separation centrifuges, transfer pumps, and modular treatment systems. Depending on the characteristics of the oily sludge and the required treatment objectives, different process configurations can be combined to develop a suitable solution.<\/p>\n

The completion of this GNLW554-VFD decanter centrifuge highlights GN Separation’s continued development in the African market and its experience in providing separation equipment for challenging oil and gas applications. GN Separation will continue to support customers worldwide with reliable separation technologies designed to improve resource recovery, reduce waste, and enhance environmental performance.<\/p>\n","protected":false},"excerpt":{"rendered":"
