Patent number: 8641895Abstract: A method and apparatus for recovering oil from oil-containing sorbents, such as drill cuttings obtained from drilling with an oil-based mud. The method includes peptizing the substrate with an acid reagent and direct thermal desorption with combustion effluent gases at high temperature under turbulent mixing conditions. Another method disclosed includes upgrading the oil in the substrate to improve one or more of the properties of the recovered oil relative to the oil in the substrate, such as, lower aromatics content, lower sulfur content, lower functional group content, higher saturates, higher viscosity, higher viscosity index, and any combination thereof. The apparatus provides for efficient recovery of oil from the substrate with a short residence time, high throughput, low residual oil content in the treated solids and/or high percentage of oil recovery. The apparatus may be transported to a remote location for on-site treatment of drill cuttings or other oil-containing solids.Type: GrantFiled: January 14, 2013Date of Patent: February 4, 2014Assignee: Racional Energy & Environment CompanyInventor: Ramon Perez-Cordova

Patent number: 7690445Abstract: A method and apparatus for treating for disposal oil contaminated substrates, such as drill cuttings from drilling with an oil-based mud, by steam distillation. If necessary, the contaminated substrate 10 can be pretreated with an emulsion breaker 14. The contaminated substrate 10 can be treated with steam 16 in a first mixing still 12. The substrate can be optionally treated with a second steam source 20 in a second mixing still 18. The steam provides heat to vaporize the oil, moisture to treat the substrate and water to the reaction mixture. Recoverable constituents in the vapor can be condensed in a vapor collection system 24. The treated substrate 22 is essentially free of oil and can have a controlled water content. The process exhibits low energy consumption, rapid treatment, compact equipment and a high degree of process control.Type: GrantFiled: October 27, 2004Date of Patent: April 6, 2010Assignee: Racional Energy & Environment Co.Inventor: Ramon Perez-Cordova

Patent number: 6228253Abstract: A method and apparatus for decoking and suppressing coke formation during pyrolysis has been discovered that does not require complete shut down of the pyrolysis furnace. For the decoking step, the hydrocarbon feed is cut off to one or more coils for usually less than about three hours during which a decoking additive is added to the steam flow in that coil. This additive is comprised of an aqueous solution of a group IA metal salt and a group IIA metal salt and catalyzes the coke removal. The hydrocarbon feed continues in the other coils during this procedure. After decoking, a suppression additive also comprising group IA and IIA metals is added to the steam and hydrocarbon feed. This suppression additive will melt onto the inner surfaces of the pyrolysis furnace coils, coating the coils with a glass layer which inhibits coke formation.Type: GrantFiled: September 17, 1998Date of Patent: May 8, 2001Inventor: Zalman Gandman

Patent number: 5630912Abstract: An oil reclamation device includes an evaporator head and base both of heat conductive material and defining an evaporator chamber between them. An upwardly vertically extending heating element is disposed within the evaporator base for heating oil containing contaminants within the evaporator chamber by conduction and convection to evaporate light contaminants/liquids (e.g. water, fuel or antifreeze) in the oil. A vent extends from the evaporator chamber through the head, and an oil discharge conduit provides gravity discharge from the evaporator chamber and is formed in the base. An oil inlet conduit feeds oil from the head toward the evaporator chamber, preferably through a plurality of substantially evenly spaced passages formed in the head and flaring outwardly from the oil inlet conduit to the evaporator chamber to provide flow of oil in small, distinct, spaced streams to impact a portion of a generally annular frustoconical wall element extending upwardly form the base toward the head.Type: GrantFiled: January 31, 1996Date of Patent: May 20, 1997Assignee: T F Purifiner, Inc.Inventor: Byron LeFebvre

Patent number: 4853189Abstract: Process and apparatus for catalytic conversion of oils. A furnace heats a feedstock which is provided to a separator for separation of the feedstock into a gas vapor phase and a liquid phase. The liquid phase is provided under pressure to a venturi nozzle which atomizes the liquid oil. The atomized oil and the gas are each provided to a reactor such as the lower end of a riser reactor in a fluid catalytic cracking unit.Type: GrantFiled: January 23, 1987Date of Patent: August 1, 1989Assignee: Phillips Petroleum CompanyInventor: Floyd H. Holland

Patent number: 4549935Abstract: The thermodynamic efficiency of a tar sands conditioning drum is improved by continuously and simultaneously discharging steam from all the nozzles of an array of a few relatively large nozzles distributed circumferentially around the inner drum periphery rather than selectively sparging the steam only from those nozzles beneath the tar sands pulp surface. As a result, the drum shell and components above the pulp are heated and thus heat the pulp by radiation and, after entering the pulp, by convection as well as by sparging. Hot water droplets formed continuously in the steam cloud rain onto the pulp surface to provide another highly important heat transfer mechanism. Coincidentally, mechanical reliability and economics are achieved by eliminating the sparge valve and multiplicity of smaller nozzles which characterize the prior art tar sands conditioning drums.Type: GrantFiled: June 16, 1983Date of Patent: October 29, 1985Assignee: Suncor, Inc.Inventor: Shimon S. Tchernyak
