What is a Vacuum Clarifier?

 A vacuum clarifier is a long tube that forces a vacuum from both the top and from the bottom.  In essence, a vacuum clarifier stretches the water allowing free and de-emulsified water to flow to the top of the water column, while the solids that have been separated by electrocoagulation (EC) gravitate to the bottom for collection.

 EC treated water containing de-emulsified oil, water and solids enters the variable vacuum clarifier, being drawn into it by an intense vacuum.  As the water rises in the clarifier (by vacuum) the particles physically cannot follow due to the enhanced effect of gravity (induced by vacuum).  As the water and oil rise leaving behind the solids, the oil begins to separate from the water as well, due to its lighter weight (again enhanced by vacuum).  Any foam or bubbles (emulsion) is immediately broken by the degassing effect of the intense vacuum.  Settled solids are removed from the cone bottom of the clarifier by a progressive cavity sludge pump and are suitable for land disposal with no further treatment.  Solids from the clarifier can be taken off at between 20% to 50% solids content, thus no further dewatering is required of these discharged solids.  Clarified water is drawn off the tube just below that of the static oil level and is sent directly to the distiller for chloride removal.  No further filtration or treatment is of the water is required prior to entering the distiller.  Oil rises to the top of the clarifier tube and is drawn off by gravity, aided by the induced vacuum of dropping approximately 40 feet to ground level.  NOTE:  the upper level of the vacuum clarifier contains heating tubes to help liquefy the heavy crude.  Oil thus treated will have less than ½% water remaining in the oil, due to the effects of heat, electrocoagulation and vacuum.
