Abstract
A centrifugal, liquid-liquid separator relies on a sweep flow in excess of the flow rate naturally occurring in the heavy constituent or species being separated out from a lighter species, in order to prevent access by the long-chain polymers of the lighter species to solids that may separate out and make a durable composition of polymers and particles that adheres and compacts against the shell wall of the centrifuge.
