Solids removal from viscous liquids

摘要: What is disclosed a method for treating hydrophobic viscous feed, such as syncrude fraction containing solids, to remove at least portion of the solids having minimum therewith, characterized by multi-step process. First, water mixed with feed provide two liquid phases in mixture. The mixture then subjected one electric field electrostatic zone produce first overflow product, fraction, that reduced content compared original and an water, residual feed. Next, underflow centrifuged second primarily minor amount liquids. At part returned recovery Also are improvements basic process; including those which, singly or combination, diluent added; plurality zones centrifuging employed; flashing step specific apparatus carrying out steps.
