The Dynamic Centrifugal Coalescer increases the performance of produced water separation systems. It is a combination of centrifugal forces and coalescing effect. An element consisting of thousands of PTFE tubes (pore size 1.5 mm) rotates inside the pump. Because of the centrifugal force, the droplets of the oil, coalesce on the walls of the tubes. Oil droplets as small as 1 micron are collected and turned into droplets up to 100 micron. The DCC is a non-plugging coalescing technology and a proven solution for increasing performance of produced water treatment.
