The invention relates to a plant complex for steel production comprising a blast furnace for producing pig iron, a converter steel mill for producing crude steel, a gas-conducting system for gases that occur when producing the pig iron and/or the crude steel, and a power-generating plant for electricity generation. The power-generating plant is designed as a gas-turbine power-generating plant or gas-turbine and steam-turbine power-generating plant and is operated with a gas that comprises at least a partial amount of the blast-furnace top gas that occurs in the blast furnace and/or a partial amount of the converter gas. The plant complex additionally comprises a chemical plant and a biotechnological plant, the power-generating plant, the chemical plant and the biotechnological plant being arranged in a parallel setup with regard to the gas supply. The gas-conducting system comprises an operationally controllable gas-distributing device for dividing the streams of gas.

The invention relates to a method for producing syngas in combined operation with a metallurgical plant which comprises at least one blast furnace for producing crude iron, a converter steel mill and a coke-oven plant. Part of the blast-furnace top gas that is produced in the production of crude iron and/or part of the converter gas that occurs in the converter steel mill and/or part of the coke-oven gas that is produced in the coke-oven plant are mixed. By choosing the gas streams that are brought together to form a mixed gas and/or by changing the mixing ratios of the gas streams that are brought together, at least two streams of useful gas are produced, differing with regard to their composition and respectively prepared to form streams of syngas.

The invention relates to a plant complex for steel production comprising a blast furnace for producing pig iron, a converter steel mill for producing crude steel, a gas-conducting system for gases that occur in the production of pig iron and/or in the production of crude steel, and a power-generating plant for electricity generation. The power-generating plant is operated with a gas that comprises at least a partial amount of the blast-furnace top gas that occurs in the production of pig iron and/or a partial amount of the converter gas. According to the invention, a chemical or biotechnological plant is provided and connected to the gas-conducting system and arranged in parallel with the power-generating plant with respect to the gas supply. Externally obtained electricity and power-generating plant electricity are used to cover the electricity demand of the plant complex.

Plant combination for producing steel and method for operating the plant combination

The invention relates to a plant complex for steel production comprising a blast furnace for producing pig iron, a converter steel mill for producing crude steel and a gas-conducting system for gases that occur in the production of pig iron and/or in the production of crude steel. According to the invention, the plant complex additionally has a chemical or biotechnological plant connected to the gas-conducting system and a plant for producing hydrogen. The plant for producing hydrogen is connected to the gas-conducting system by a hydrogen-carrying line. Also the subject of the invention is a method for operating the plant complex.

Textile fabrics having a self cleaning and water repellent surface, constructed from

Flat textile structures with self-cleaning and water-repellent surface

The present invention relates to self-cleaning surfaces having improved mechanical stability and a process for the production thereof. The present invention is achieved by producing self-cleaning, hydrophobic, structured surfaces having mixtures of particles, which are fixed on their surface and which comprise structure-producing particles selected from semimetal or metal oxides, silicas and metal powders, and wax particles. Structured surfaces that are structured by such mixtures of particles are distinguished by substantially higher mechanical stability of the structure and are therefore especially suitable for the production of self-cleaning surfaces, which are exposed to relatively high mechanical loads, such as, for example, the surfaces of tarpaulins, awnings, greenhouse elements, conservatories or truck tarpaulins.

Process for forming a surface comprising elevations of hydrophobic particles

The invention relates to surfaces with hydrophilic properties and a method for producing such surfaces. Surfaces are provided with hydrophilic properties by applying a coating containing hydrophilic silicic acid by means of the inventive method. Said surfaces can be textile or polymer surfaces, metallic or wooden surfaces. The silicic acid can be permanently connected to the polymer surface or be in the form of a non-fixed coating. The inventive hydrophilic silicic acid is applied in a very simple manner by applying a suspension containing silicic acid particles in a solvent on the corresponding surface, whereupon the solvent is removed or the silicic acid particles are fixed to the surface by means of a carrier. Condensing devices of dehumidifiers, foams or sponges are examples of surfaces that can be provided with the inventive hydrophilic surfaces.

Hydrophilic surfaces

The present invention describes a process for preparing a surfactant-free suspension including hydrophobic particles and at least 50.01% by weight of water, where hydrophobic, nanostructured particles are suspended in at least one organic solvent miscible with water and having a boiling point below 150&#xb0; C., and then this concentrated organic suspension is intensively and thoroughly mixed with surfactant-free water.

Method for producing a surfactant-free suspension based on nanostructured, hydrophobic particles, and use of the same

Textiles coated with self-cleaning surfaces which contain hydrophobic nanostructured particles protruding from a coating having hydrophilic properties are provided.

Coated textile with self-cleaning surface

Self-cleaning surfaces comprising elevations formed by hydrophobic particles and having improved mechanical strength

The present invention relates to a vapor-pervious water-impervious substrate, preferably a fibrous nonwoven web, which can be used in particular as a textile continuous sheet material, for example as an awning or as an inlet in apparel. The substrate according to the present invention may have self-cleaning properties. The substrate according to the present invention is simple to produce in an at least two-step process wherein a coating on the fibers of the substrate is produced in the first step and then hydrophobic particles are applied to the coated fibers by means of an adhesion promoter.

Textile substrates having self-cleaning properties

The invention relates to a process for producing self-cleaning surfaces on coated textile sheets, by the following steps of the process:

Production of self-cleaning surfaces on textile coatings

The invention relates to mold-release agents, in particular mold-release agents which can be used for demolding moldings from molding tools, and also to the use of these mold-release agents. The mold-release agents of the invention, which are preferably based on suspensions of nanostructured microparticles, have the advantage of being markedly more environmentally compatible than the known mold-release agents based on organic or organosilicon compounds, since they can remain on the surfaces of the moldings. The use of the mold-release agents of the invention is very simple, since advantage can be taken of existing equipment. An example of a usual method is to produce injection moldings by means of injection molds into which the material is injected. The mold-release agent of the invention is applied, e.g. by spray-application, to the injection mold prior to the actual injection-molding process. Depending on the setting of the molding parameters, the microparticles are impressed into the surfaces of the moldings and anchored, and therefore another favorable effect is that the surfaces of the injection molding can have self-cleaning properties.

Release agents comprising hydrophobic, nanoscalar particles, and the use of these mold release agents

Disclosed are a process for producing a suspension of hydrophobic oxidic particles which has a defined, adjustable viscosity, which comprises suspending low structured hydrophobic oxidic particles in at least one organic suspension agent and then adding from 0.05% to 15% by weight based on the suspension medium of high structured hydrophobic oxidic particles, a suspension of hydrophobic oxidic particles which has a defined, adjustable viscosity and the use thereof for producing soil and water repellent coatings on articles.
