Nitrogen process for production of ammonia and liquid hydrogen
A method of co-producing liquid hydrogen and ammonia, including a hydrogen generator, a nitrogen generator, and a HLU is presented. The method includes pressurizing a hydrogen stream from the hydrogen generator in a hydrogen compressor, dividing the pressurized hydrogen into at least a first portion and a second portion, wherein the first portion includes at least part of the flow of a first refrigeration cycle in the HLU, and the second part comprises at least part of the feed to an ammonia plant. The method also includes pressurizing a nitrogen stream from the nitrogen generator in a HP nitrogen compressor, dividing the pressurized nitrogen stream into at least a first part and a second part, wherein the first part comprises at least part of the flow of a second refrigeration cycle in the HLU, and the second part comprises at least part of the feed to the ammonia plant.

Ammonia converter comprising a tubular inner wall
A vertical ammonia converter with radial flow catalyst beds includes a recipient having an outer shell equipped with a dual duct inner tubular wall to route effluents in upward and downward directions, the tubular wall made of vertical tubes with gastight walls arranged in a circle on an outer periphery of an inner wall of the shell, open at their ends to route effluent to be treated in the upward direction from an injection chamber in a lower part of the shell to a distribution chamber in an upper part of the shell, which tubes are contiguous to a filtering media over a height of a catalyst bed, the filtering media open at an upper end to pass a downward-flowing effluent and closed at a lower end to route and distribute the effluent through their effluent-permeable face towards the catalyst bed retained on an outer face by the filtering media.
Adiabatic multi-bed catalytic converter with inter-bed cooling
A multi-bed catalytic converter (1) with inter-bed heat exchangers, comprising a plurality of superimposed catalytic beds and a common heat exchanger (5) which is shared between two or more consecutive catalytic beds, said common heat exchanger including heat exchange bodies such as a tube bundle (6), and a wall system (9, 10) to define a tube side and a shell side respectively, and the shell side comprising at least a first space (12) and a second space (13), wherein the first space (12) receives the product gas leaving the first of said consecutive beds, and the inter-cooled gas leaving said first space (12) is admitted in the second bed (3-3) for further conversion, and a sealing means (14) preventing a direct gas passage from said first space to said second space.
