Abstract: A method for the regeneration of residues containing sulphur is characterized in that a droplet stream containing fuel is introduced into the reactor simultaneously with the droplet stream containing the residue and is fed into a pre-reaction zone that is created by feeding in an oxygen-rich gas stream, whereby the residue in the pre-reaction zone is partially thermally cleaved and subsequently fed into the reaction zone.

Abstract: When waste glass that is strongly laden with organic impurities is melted, the organic constituents present in the melt give rise to so-called “black hearts” which can no longer be eliminated in a subsequent refining process, thus impairing the quality of the glass. According to the invention, gas nozzles for introducing oxygen are installed in the area of the inlet opening of a melting unit thermally connected to a combustion chamber. This allows a targeted oxidation of the organic constituents, which are then exhausted in the form of exhaust gas. With the invention, even highly contaminated waste glass such as, for instance, glass fibers, can be returned to the production process.

Abstract: According to a known method for producing a component by means of a powdery starting material, powder is mixed with auxiliaries comprising binding agents, whereby a free-flowing mass is produced. A green body is produced from the mass by means of powder injection moulding. A portion of the auxiliaries is extracted by heating the green body in a container and exposing said body to a stream of solvents. The green body is sintered, whereby the component is produced. The aim of the invention is to enable fast and gentle extraction for releasing green bodies which are produced by means of powder injection moulding. According to the invention, the extraction comprises a heating-up phase during which the temperature of the green body is permanently or gradually increased and the green body is overflown by solvent in the form of a compressed, supercritical treatment gas.

Abstract: The aim of the invention is to produce a spray burner, starting from a conventional spray burner, for the atomisation and combustion of sulphur-containing residues, comprising a residue nozzle, for the introduction of sulphur-containing residue, which is surrounded by an outer nozzle, for the introduction of an atomising agent, whereby said burner is suitable for a method in which oxygen can be introduced in the cracking oven as additional oxidising agent to increase the capacity and improve the economic efficiency without the above disadvantages and limitations and is also optimised for a variable throughput of residue for atomising. Said aim is achieved whereby the residue nozzle comprises a multiplicity of individual nozzles which may be switched on and off, connected to an input for the residue, an inlet for fuel is provided and the outer nozzle is connected to an inlet for an oxygen-enriched gas stream.

Abstract: According to a conventional method for incinerating organic waste material, a fluidization device causes an oxygenous fluidizing gas to flow through the waste material, which is located in an incineration chamber, from underneath while forming a fluidized particle layer and the waste material is incinerated. The resulting flue gas is withdrawn via an open space situated above the particle layer and is subjected to a secondary incineration in a secondary reaction zone or secondary incineration chamber. Expanding upon the prior art, the aim of the invention is enable a high throughput for the incineration material while resulting in a low level of nitrogen oxide production, and to increase the productivity for the incineration of organic waste material. To these ends, the invention provides that the fluidized particle layer (3) is concentrated with oxygen in such a manner that a mean oxygen content ranging from 0-3 vol. % is set in the open space (6).

Abstract: The starting point is a process to improve the performance of the incineration of combustible waste material in an incineration chamber, whereby the waste material is conveyed to a burner flame where it is burned with combustion air at a temperature in the range from 1100° C. to 1700° C. [2012° F. to 3092° F.]. On this basis, in order to create a process that allows a capacity increase of installations employed for the exothermal incineration of waste materials, it is proposed according to the invention that at least part of the combustion air is replaced by an oxygen-rich gas having an oxygen content that is higher than that of air and that the oxygen-rich gas is mixed with a cooling medium.

Abstract: In a prior-art method to regulate the pressure inside a cryogenic tank containing cold gas when a main stream for a consumer is withdrawn, heated gas in the form of a heating gas secondary stream, which is regulated as a function of the tank pressure, is fed through the cryogenic tank via a pipe. In order to start on this basis and to provide a simple and safe operating method to regulate the main stream and the secondary stream while also providing a cost-efficient device for this purpose, it is proposed by the method according to the invention that the secondary stream and the main stream be fed to a pressure-control means equipped with a first adjustable throttle for the secondary stream and with a second adjustable throttle for the main stream, whereby the throttles are coupled to each other in such a way that they can be opened and closed in opposite directions as a function of the pressure in the tank.

Abstract: A process for separation of an oil-containing aqueous emulsion includes mixing the oil-containing aqueous emulsion with carbon-dioxide and subjecting the emulsion and carbon dioxide for a specified time within an autoclave to an elevated pressure and an elevated temperature. A rising stream of bubbles is formed within the autoclave by suddenly relieving the pressure within the autoclave with the rising stream of bubbles serving to separate the oil-containing aqueous emulsion into an oil-rich phase and an oil-depleted emulsion. The oil depleted emulsion is transferred to a segrating tank. At least a fraction of the oil-depleted emulsion within the segregated tank is subjected to ultrafiltration to separate the fraction into a permeate and a retentate.
