Nozzle centrifuges are continuously operating machines that clarify liquids while concentrating solids. The concentrated solids are discharged continuously through nozzles. The clarified liquid is discharged by a built-in centripetal pump.

These ready-to-use treatment systems have been designed for the efficient dehydration and desalting of crude oil. At the heart of each modular system is a high-performance centrifugal separator which can be flexibly supplemented by additional units. The easy-to-integrate treatment system can be customized for various process setups and stages in both upstream and downstream processes.

Oil and gas production installations have to meet their quotas 24 hours a day. Drilling rigs and production installations in ice-cold Siberia are subject to background and process conditions which are fundamentally different to those encountered in installations in extremely hot desert regions or FPSOs on the world’s oceans. Whatever the conditions or location – the overriding priority has been unchanged for years: The machines have to run. 24 hours a day.

Manual cleaning separators with solid-wall bowl and single centripetal pumps are today mostly used for the treatment of lube and turbine oil in power plant applications. They are suitable for clarifying or purifying oils with a low solids content of up to 0.01 percent by vol.

The decanter’s hour has come as soon as the solids content in the suspension to be processed is particularly high. These machines provide the benefits of high clarifying efficiency and maximum dewatering as well as the separation of liquids with the simultaneous removal of solids. The main requirements in this respect include a high bowl speed, a powerful drive for the scroll and a scroll speed which automatically adapts to the solids loading in the feed.
