A method of heat energy recovery in installations including at least one reformer, wherein, for the purpose of heat energy recovery, process condensate is preheated and/or evaporated on a cooling section of the installation by heat exchange with gas generated in the installation, in particular synthesis gas, wherein, prior to being preheated in a flue gas duct of the installation, combustion air is preheated by heat exchange by means of boiler feed water. The invention also relates to a heat energy recovery system for the implementation of the method.

Method and arrangement for heat energy recovery in systems comprising at least one reformer

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.

Method for generating synthesis gas in conjunction with a smelting works

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.

Combined system for producing steel and method for operating the combined system

The invention relates to a process for preparing ammonia gas and COfor urea synthesis. In the process of the invention, a process gas containing nitrogen, hydrogen and carbon dioxide as main components is produced from a metallurgical gas. The metallurgical gas consists of blast furnace gas, or contains blast furnace gas at least as a mixing component. The process gas is fractionated to give a gas stream containing the COcomponent and a gas mixture consisting primarily of Nand H. An ammonia gas suitable for the urea synthesis is produced from the gas mixture by means of ammonia synthesis. COis branched off from the CO-containing gas stream in a purity and amount suitable for the urea synthesis.
