A plant for refining raw materials containing organic constituents includes a reactor configured to receive raw materials; a furnace configured to receive solids and fuel from the reactor; a return conduit configured to recirculate hot solids generated in the furnace to the reactor; and a sealing device configured to separate an oxidizing atmosphere of the furnace from an atmosphere of the reactor. The sealing device includes: a downpipe disposed between the furnace and the reactor, the downpipe being configured to withdraw a stream of solids from the furnace; a rising pipe disposed near a bottom of the downpipe and branching off there from to a top, the rising pipe being configured to transport a fluidized stream of solids to the reactor; and a conveying gas supply disposed below the rising pipe, the conveying gas supply being configured to fluidize a stream of solids withdrawn from the furnace.

A process for dedusting a dust laden vapor gas mixture (VGM) obtained by pyrolysis of a material containing hydrocarbons includes treating the dust laden VGM in a dry electrostatic precipitator at a temperature in a range from 380 to 480&#xb0; C. so as to separate dust from the VGM. Then, the VGM is cooled to a temperature in a range from 310 to 360&#xb0; C.

A process for producing hydrogen for use in a subsequent methanation process includes electrochemically converting water into hydrogen and oxygen. The hydrogen is depleted with electrolyte aerosols. Then, the electrolyte aerosols are separated from the depleted hydrogen in a wet electrostatic precipitator in a hydrogen atmosphere.

A process for winning oil from a vapor gas mixture (VGM) containing a plurality of oil fractions obtained by the pyrolysis of a hydrocarbon containing material includes dedusting and cooling the VGM. The dedusted and cooled VGM are fractionated in at least two electrostatic precipitator stages at respective temperatures corresponding to respective boiling points of the oil fractions so as to separate the oil fractions.

A process for refining raw materials containing at least one of oil and bitumen includes supplying the raw materials to a reactor and volatilizing fuel gas in the reactor at a temperature of from 300 to 1000&#xb0; C. and a pressure of from 0.001 to 1 bar. Solids remaining in the reactor, including non-evaporated fractions of heavy hydrocarbons, are introduced into a furnace. A staged combustion of the non-evaporated fractions of heavy hydrocarbons is performed in a substoichiometric stage and in a superstoichiometric stage in the furnace at a furnace temperature of from 600 to 1500&#xb0; C. as to obtain hot solids in the furnace. The hot solids are recirculated from the furnace into the reactor. A sealing device separates an oxidizing atmosphere of the furnace from an atmosphere of the reactor.

A process for lowering the carbon content in ash includes introducing the ash having a carbon content of 1 to 20 wt-% into a reactor where the ash is burnt at a temperature between 700 and 1100&#xb0; C. Fuel is also introduced into the reactor. During combustion, microwave radiation is fed into the reactor. At least part of the energy released during the combustion is recovered.

A process for refining oil-containing includes introducing the oil-containing solids to a reactor so as to expel an oil-containing vapor from the solids at a temperature of 300 to 1000&#xb0; C. The oil-containing vapor expelled from the reactor is supplied to a cracker so as to crack heavy oil components of the oil-containing vapor. The cracked heavy oil components obtained in the cracker are separated and withdrawn from the cracker. The solids left in the reactor and an unevaporated fraction of heavy hydrocarbons are introduced into a furnace. The unevaporated fraction of heavy hydrocarbons in the furnace are burned at a temperature of 600 to 1500&#xb0; C. The solids from the furnace are recirculated into the reactor. A conveying gas is supplied into a rising pipe, wherein the stream of solids withdrawn from the furnace is fluidized by the conveying gas and transported to the reactor through the rising pipe.

The present invention is concerned with a process and a plant for the production of sulphuric acid wherein a sulphur dioxide-containing feed gas is converted, at least in part, with oxygen in at least two contact stages of main contacts arranged in series, to generate sulphur trioxide, and wherein generated sulphur trioxide-containing gas is conducted to an absorber and converted therein to sulphuric acid. In order to be able to economically process feed gases of a sulphur dioxide content of between 13 and 66% by volume to sulphuric acid, using conventional catalysts, it is suggested to withdraw from a contact stage connected upstream of the last main contact stage, a partial stream of the sulphur dioxide- and sulphur trioxide-containing gas, to mix the said partial stream with the feed gas to generate a contact gas of a sulphur dioxide content of more than 13% by volume, and to return the same to the first contact stage.

An electrolyte line extends from the outlet of an electrolysis device to a collecting tank and from the same back to the inlet of the electrolysis device. The electrolyte is passed from the outlet of the electrolysis device to a first container which is disposed at a higher level than a second container. Electrolyte collected in the first container is periodically discharged through a first syphon line into the second container, and electrolyte collected in the second container is periodically discharged through a second syphon line into the collecting tank which is disposed at a lower level than the second container. The outlet end of each syphon line is disposed at a distance above the liquid level of the container disposed thereunder, so that electrolyte always flows only in one of the two syphon lines or in none of the syphon lines. When electrolyte flows in none of the two syphon lines, electrolyte is preferably supplied from the collecting tank into the second container.

This upper region of the cell is sprayed or irrigated with the ion-conductive liquid and the electrode surface at least partially wet. During this wetting process, the gas flows across the electrode surface.
