EVTNModel OS507 -Dynamic Centrifugal Coalescer

SHARE

The dynamic centrifugal coalescer increases the performance of produced water separation systems.  Its effect is a combination of centrifugal force and a coalescer.  An element (core) consisting of thousands of tubes (pore size 0.4 - 1.4mm) is rotated.  The multi-phase liquid with different mass-densities passes through the core.  Because of the centrifugal force, the droplets of the discontinuous phase coalesce on the walls of the tubes.  Oil droplets >5 micron increase up to 200 micron.  The DCC is a non-plugging coalescing technology and a proven solution for increasing the performance of produced water treatment systems.
