Patent number: 9370806Abstract: The present invention is directed to a method and system of processing and removing hydrocarbon sludge from a tank wherein the hydrocarbon sludges are the product of gravity settling in the bottom of the tank to form a sludge consisting of inorganic and organic materials not readily flowable or pumpable for removal in the found state and where a process is used to selectively separate, grind, disperse and suspend these materials with a mechanical classifier system, and where flow agents may be metered to effect a slurry stream directed thru a nozzle system towards the sludge in the tank and by reducing the surface tension and mechanical conditioning of the sludge, create a pumpable slurry that may be removed from the tank with minimal time, cost and environmental impact.Type: GrantFiled: September 9, 2011Date of Patent: June 21, 2016Assignee: JR & JH HOLDINGS LLCInventor: John C.

Publication number: 20080023039Abstract: Systems and methods for cleaning sludge from a large tank. The sludge from the interior of storage tanks is mobilized using a metered flow agent stream and then subjected to a mechanical comminution or high shear action, e.g. by grinding or chopping. This produces a pumpable slurry which is then recirculated back into the tank to further mobilize sludge.Type: ApplicationFiled: May 7, 2007Publication date: January 31, 2008Applicant: JR & JH Holdings, LLCInventor: John Hancock

Publication number: 20080023040Abstract: Methods and systems for operating a facility which stores large quantities of petroleum. When the large storage tanks need cleaning or sludge abatement, the sludge from the interior of storage tanks is mobilized using a metered flow agent stream, and then subjected to a mechanical comminution or high shear action, e.g. by grinding or chopping. This produces a pumpable slurry which is then recirculated back into the tank to further mobilize sludge. This cleaning technique results in a faster cleaning process. This also provides a process which is less exposed to uncertainties in the composition of the sludge, e.g. to how much rust or scale is present in the sludge. Since the duration of downtime for cleaning is shorter AND less uncertain, tank cleaning can be scheduled into smaller schedule gaps, resulting in less capital cost (for downtime) and lower maintenance budget overall (since developing leakage problems can be caught sooner).Type: ApplicationFiled: May 7, 2007Publication date: January 31, 2008Applicant: JR & JH Holdings, LLCInventor: John Hancock
