A method for purifying an asphaltene-containing fuel where the asphaltene-containing fuel is supplied to a deasphalting unit in which asphaltene contained in the fuel is separated using a solvent, thereby forming a substantially deasphalted fuel. The solvent is separated from the deasphalted fuel in a solvent recovery unit after a successful separation of the asphaltene from the fuel, and the waste heat of turbine exhaust gas produced in a gas turbine when converting fuel into electricity is used in order to purify the asphaltene-containing fuel. A corresponding device is used for purifying an asphaltene-containing fuel.

A method and a device for preparing a vanadium-containing combustible in a de-asphalting device. In this way, a vanadium-containing combustible is supplied to a de-asphalting unit via a supply line in a de-asphalting device, wherein the vanadium-containing combustible supplied into the de-asphalting unit forms a first mass flow and a substantially de-asphalted combustible is discharged from the de-asphalting unit via a discharge line. A bypass line is connected to the supply line, wherein, via the bypass line, a second mass flow of the vanadium-containing combustible is directed past the de-asphalting unit in parallel to the first mass flow and supplied to the discharge line, such that a combined mass flow is formed in the discharge line.

An apparatus for separation of asphaltenes from an oil-containing fuel, has a mixing element for intensive mixing of the oil-containing fuel with a solvent to form a solution supersaturated with asphaltenes, a vessel for reducing the oversaturation by depositing the asphaltenes out of the supersaturated solution, a growth zone formed within the vessel for growth of asphaltene particles present via the asphaltenes separated out of the supersaturated solution, and a classifying unit connected in terms of flow to the vessel for separation of the asphaltene particles grown in the growth zone in terms of their particle size, wherein the vessel is formed and set up such that a stream containing asphaltene particles circulates between the mixing element and the growth zone of the vessel. A corresponding process has a stream containing asphaltene particles that circulates between the mixing element and the growth zone of the vessel.

A method for separating carbon dioxide from a gas stream, in particular from a flue gas stream, wherein, a gas stream is brought into contact with a washing medium in an absorber of a separation device and the carbon dioxide contained in the gas stream is separated; the charged washing medium is supplied to a desorber of the separation device to release the carbon dioxide; a vapor stream is removed from the desorber and is supplied to a cooling unit to form a condensate; degradation products, in particular nitrosamines, contained in at least a partial stream of the condensate are photolytically decomposed to decomposition products; at least the decomposition products, in particular nitrites and amines, are removed; and at least a partial stream of the condensate is returned to the desorber. A corresponding separation device separates carbon dioxide from a gas stream.

A processing unit for a liquid washing medium contaminated with sulphur oxides and/or nitrogen oxides, has an evaporation stage for concentrating the active components of the washing medium by an evaporator and/or by a heat exchanger, and has a collecting tank connected to the evaporator and/or to the heat exchanger. The collecting tank is configured as a crystallizer for removing sulfur oxides from the washing medium by crystallization of a sulphate, in particular of potassium sulphate. A separating device for carbon dioxide has a corresponding processing unit, and a method for processing a washing medium contaminated with sulphur oxides and/or nitrogen oxides uses a corresponding processing unit.

A method for separating carbon dioxide from a gas flow, in particular from a flue gas flow, where a gas flow is brought in contact with a scrubbing medium in an absorber of a separating device and carbon dioxide contained in the gas flow is separated, the loaded scrubbing medium is fed to a desorber of the separating device in order to release the carbon dioxide, a vapor flow is drawn from the desorber and is fed to a cooling device in order to form condensate, and the condensate formed in the cooling device is at least partially fed to a purifying device, in which degradation products contained in the condensate are removed by reverse osmosis and/or by an ion exchanger. A separating device is adapted for separating carbon dioxide from a gas flow.
