Abstract: Systems and methods for extracting recoverable materials from source materials are provided. Source materials are introduced into a furnace. A condition is created within the furnace in which a gaseous pressure within the furnace is less than an atmospheric pressure outside of the furnace by removing air from within the furnace with a vacuum pump. Hydrocarbons contained within the source material are separated from the source material without using a significant amount of water by heating the source material to a temperature sufficient to cause the hydrocarbons to liquefy or vaporize. The liquefied hydrocarbons or vaporized hydrocarbons are then captured.

Abstract: Systems and methods for coal liquefaction are provided. According to one embodiment, coal is introduced into a plasma furnace. A plasma energy field is generated within the plasma furnace by causing an electrical discharge between a pair of arc rods located within the plasma furnace and positioned above the coal. Hydrocarbons contained within the coal are separated from the coal by causing the plasma energy field to penetrate the coal and heat the coal to a temperature sufficient to liquefy the hydrocarbons by focusing and drawing the plasma energy field through the coal with a magnetic field created proximate to the coal. The liquefied hydrocarbons are then captured.

Abstract: The invention may be used at installations with both an atmospheric column, and those with simultaneous application of an atmospheric column and a vacuum one and intended for fractional distillation of oil. The main distinctive feature of the method lies in the fact the hydrocarbon material is affected through primary and principal excitation by means of electromagnetic vibrations. The primary influence upon the hydrocarbon material is carried out prior to its feeding for thermal cracking, while the, principal influence is fulfilled in the rectifying column. For the method to be implemented, the primary excitation source in the installation is realized in a form of an electromagnetic oscillator, and the rectifying column is realized with possibility of resonance excitation provided, being the main exciter of the hydrocarbon material. The invention makes it possible to increase the percentage of output of lighter fractions, as well as to raise the quality of processing of raw materials.

Abstract: An improved oil reclamation device for removing contaminates from lubricating oils and hydraulic fluids. A first feature of this oil reclamation device an improved utilization of space, which provides the benefit of a compact installation. Another benefit of this design is an efficient design of the second chamber, which virtually eliminates cold spots and vapor condensation. Another benefit of this design is the efficient use of operating oil to heat the evaporation surface evenly and effectively without the need of any additional heat source. This design eliminates cold spots on the evaporation surface and the need for potentially dangerous heating elements. A further benefit of this design is an oil metering system which is highly resistant to clogging and easily serviced.

Abstract: For the processing of waste oil, i.e. environmentally safe processing, a process and installation are used whereby the waste oil is preheated with the distillation gases and is then distilled itself by burning the distilled waste oil. The liquid and solid residues are exposed to the flame produced by the combustion of the distilled waste oil, while the gaseous residues are heated to over 1,200.degree. C. in a long-hold chamber constructed as a fume incinerator. In order to calcine the solid or burn the liquid residues, they are collected in the distillation chamber and transported via a rotating cylinder and a chute into the combustion chamber where they are then correspondingly calcined by the burner flame. In contrast, the gaseous residues are fed to a long-hold chamber, whereby the latter is a pipe system with a length of 75 m or more.

Abstract: Apparatus for the treatment of a liquid hydrocarbon charge containing solids or solids-forming contaminants, e.g., inorganic solids, metals and asphaltenes, which includes a contactor vessel having a liquid charge inlet, a vaporizing media inlet above the charge inlet and a vapor-solids outlet. An atomizer is positioned in the charge inlet for forming small particles of the liquid charge and directing the particles of liquid in a substantially horizontal flat pattern into the contactor vessel. A premix downcomer having a dispersion grid positioned therein is located in the vaporizing media inlet for introducing a fluidized mixture of a gas dispersion media and hot circulating solid particles into the contactor vessel in a substantially vertical flat pattern to traverse the path of the liquid particles and intimately contact the liquid particles.

Abstract: In the past, it has proven difficult to separate dirt and water from petroleum emulsions of the type found, e.g. in settling ponds. A relatively simple apparatus for effecting such separation includes a sifter or screening device for removing large solid impurities from the emulsion, a preheater for reducing the viscosity of the emulsion, a centrifuge or filter for separating most of the dirt particles from the emulsion, a settling tank for receiving the emulsion from the dirt separator, and an evaporator for separating most of the water from the petroleum. The dirt removed in the dirt separator with residual oil attached thereto is mixed with a fuel oil and burned to create the heat necessary to evaporate the water. The petroleum separated in the evaporator is cycled through the preheater for heating incoming dirty petroleum emulsion. The evaporator contains trays carrying a plurality of rows of tubes. The water-containing emulsion is fed into the uppermost tray into heat exchange contact with the tubes.
