A method for removing acidic gases from waste gases is disclosed. The invention relates to a method for removing acid gases, in particular from SOand NO, by contacting the waste gas with an emulsion of water in organic sulfoxides, in particular of water in oil-derived-sulfoxides. The organic sulfoxide phase can be regenerated after the emulsion is loaded with polluants, by letting the emulsion to settle down and separate into two phases. The aqueous phase obtained after the separation contains sulfate and nitrate ions which can be collected and used as valuable chemicals.

Method for removing acidic gases from waste gas

Apparatus for generating power includes a gas turbine unit having a compressor for compressing ambient air and producing compressed air, a combustion chamber to which the compressed air is supplied, a source of relatively high grade fuel for burning in the combustion chamber and producing combustion gases, and a gas turbine connected to generator and to the compressor for expanding the combustion gases and producing exhaust gases. The apparatus further includes a combustor that burns relatively low grade fuel, and produces combustion products, and an indirect contact heat exchanger responsive to the combustion products for heating the compressed air before the latter is applied to the combustion chamber, and for producing cooled combustion products. In addition, an energy converter is provided having an organic working fluid responsive to the exhaust gases for converting heat in the exhaust gases to electricity. Finally, the apparatus of the invention serves to minimize the consumption of high grade fuel in the presence of changes in the heating value of the low grade fuel.

Method of and apparatus for generating power

In accordance with the present invention, a method for supplying solid material such as hot carbonaceous material from a pyrolyzer or reactor to a furnace, is provided comprising providing a screw conveyor for receiving the solid carbonaceous material from the pyrolyzer or reactor preferably from above the conveyor and transporting it along its length to a vaned rotor preferably positioned on the axle of the screw conveyor preferably substantially near the end of the screw conveyor for supplying the carbonaceous material to the furnace.

Method of and means for producing combustible gases from low grade fuel

Asphaltene and oil shale are pyrolyzed at substantially atmospheric pressure for producing combustible products and carbonaceous material. A combustor combusts the carbonaceous material and produces flue gases which are supplied to a utilization device, and hot ash which is fed back to the pyrolyzer.

Method of producing combustible products from heavy fuel residue

A power plant includes a gas turbine unit having a compressor for compressing ambient air, a burner for burning fuel and heating air compressed by said compressor, and a turbine for expanding air heated by said burner to drive said compressor and produce hot exhaust gases. The plant further includes a combustor for containing particles of solid fuel which are fluidized by the exhaust gases from the turbine to produce hot products of combustion that include coarse ash particulate. Apparatus is provided for generating power from the hot products of combustion.

Multi-fuel, combined cycle power plant

Oil shale having a relatively wide range of heating value is combusted by supplying the oil shale and a further fuel having a heating value greater than the heating value of the oil shale to a combustor. The oil shale is fed to the combustor at a substantially fixed rate, independently of the heating value of the oil shale, and the further fuel is fed to the combustor at a rate such that the heating value of the fuel in the combustor remains substantially constant in the face of variations in the heating value of the oil shale. Preferably, the temperature of combustion of the products of combustion is the parameter used to control the rate at which the further fuel is fed to the combustor.

Method of and apparatus for efficiently combusting oil shale

A hydrocarbon source feed is upgraded using a solvent deasphalting (SDA) unit employing a solvent having a critical temperature T.sub.c by initially separating from a first hydrocarbon input stream fractions with an atmospheric equivalent boiling temperature less than about T.sub.f .degree. F. for producing a stream of T.sub.f.sup.- fractions and a residue stream (T.sub.f.sup.+ stream), where T.sub.f is greater than about T.sub.c -50.degree. F. In the SDA unit, a second hydrocarbon input stream which includes the residue stream is deasphalted for producing a first product stream of substantially solvent-free asphaltenes, and a second product stream containing substantially solvent-free deasphalted oil (DAO). The source feed may be included in either the first or second input streams. The DAO in the second product stream is thermally cracked for producing an output stream that includes thermally cracked fractions and by-product asphaltenes produced by thermally cracking the DAO. Finally, at least some the said thermally cracked fractions are included in the first input stream.

Apparatus for generating power utilizing lowgrade and high grade fuels

Combustible gases from a solid fuel are produced by pyrolyzing the fuel in a pyrolyzer which also produces carbonaceous material. The carbonaceous material from the pyrolyzer is combusted in a furnace to produce combustion products that include hot flue gases and ash particulate. The combustion products are separated into a plurality of streams, one of which contains flue gases, and another of which contains hot ash which is directed into the pyrolyzer. Finally, the stream of flue gases from the furnace is used to dry the fuel that is supplied to said pyrolyzer.
