摘要： A process for ammonia synthesis in a synthesis circuit may involve circulating a gas mixture comprising nitrogen, hydrogen, and ammonia with a conveying device (2) in the synthesis circuit, reacting nitrogen and hydrogen at least partly to ammonia in a converter, and cooling the gas mixture in a cooling device such that ammonia condenses out of the gas mixture. The disadvantages of adsorption drying and of absorption are avoided as hydrogen and nitrogen are introduced at mutually different sections into the synthesis circuit. The process may also involve introducing nitrogen in a flow direction upstream of the converter and/or directly into the converter in the synthesis circuit.

摘要： The invention relates to a method for producing ammonia (1), wherein a carbon-containing energy carrier flow (2) and an oxygen flow (3) from an oxygen-producing assembly (4) are fed to a synthesis gas reactor assembly (5) for obtaining a synthesis gas flow (6) with hydrogen and carbon oxides, wherein the synthesis gas flow (6) is fed to an adsorption device (7) for separating the synthesis gas flow (6) into a hydrogen flow (8), which comprises hydrogen, and a purge flow (9), and wherein the hydrogen flow (8) and a nitrogen flow (10) are fed to an ammonia reactor assembly (11) and converted into ammonia (1) there. The method is characterized in that the purge flow (9) is fed to a recovery device (12), which obtains a hydrogen-containing recovery flow (13) from the purge flow (9) and discharges a waste gas flow (14) therefrom, and that the hydrogen of the recovery flow (13) is at least partly fed to the ammonia reactor assembly (11) for conversion into ammonia (1). The invention also relates to a corresponding system for the production of ammonia (1).

摘要： Processes and systems for converting a hydrocarbon-containing feed. The feed and heated particles can be contacted within a pyrolysis zone to effect pyrolysis of at least a portion of the feed to produce a pyrolysis zone effluent and a first gaseous stream rich in olefins and a first particle stream rich in the particles can be obtained therefrom. At least a portion of the first particle stream, an oxidant, and steam can be fed into a gasification zone and contacted therein to effect gasification of at least a portion of coke disposed on the surface of the particles to produce a gasification zone effluent. A second gaseous stream rich in a synthesis gas and a second particle stream rich in heated and regenerated particles can be obtained from the gasification zone effluent. At least a portion of the second particle stream can be fed into the pyrolysis zone.

摘要： The invention relates to a method for the synthesis of ammonia, in which a fresh gas consisting largely of hydrogen and nitrogen is compressed via a compressor and subsequently fed to an ammonia converter for conversion into a converter product containing ammonia and comprising hydrogen and nitrogen. Upstream of the compressor, ammonia is evaporated into the fresh gas in order to cool the fresh gas and to produce a cold substance mixture comprising ammonia and the fresh gas. The substance mixture is heated in a heat exchanger against at least one process stream to be cooled, and subsequently compressed via the compressor, to obtain a compressed substance mixture comprising ammonia and the fresh gas. Upstream of the circuit cooler, a gas mixture consisting largely of hydrogen and nitrogen is fed to a substance stream comprising the fresh gas. The constituents of the gas mixture are separated from the converter product and/or from the compressed substance mixture comprising ammonia and the fresh gas.
