Abstract[English]
A chemical plant is provided which comprises an air separation section (ASU), a reformer section, a water-removal section and a refrigerated separation section. A first feed of atmospheric air is separated in the ASU to produce a refrigerant stream. A hydrocarbon feed is converted to a first syngas stream in the reformer section. Water is removed from the first syngas stream and at least a portion of the resulting dried first syngas stream is separated it into at least a product stream, and a by-product stream; by means of the refrigerated separation section. Importantly, the refrigerated separation section is cooled by a refrigerant stream (e.g., nitrogen) from the ASU. A process for producing a product stream, using the plant, is also provided.[French]
L'invention concerne une usine chimique qui comprend une section de séparation d'air (ASU), une section de reformeur, une section d'élimination d'eau et une section de séparation réfrigérée. Une première charge d'air atmosphérique est séparée dans l'ASU pour produire un flux de fluide frigorigène. Une charge d'hydrocarbure est convertie en un premier flux de gaz de synthèse dans la section de reformeur. L'eau est éliminée du premier flux de gaz de synthèse et au moins une partie du premier flux de gaz de synthèse séché résultant est séparée en au moins un flux de produit et un flux de sous-produit au moyen de la section de séparation réfrigérée. De manière importante, la section de séparation réfrigérée est refroidie par un courant de fluide frigorigène (par exemple, de l'azote) provenant de l'ASU. L'invention concerne également un procédé de production d'un flux de produit, à l'aide de l'installation.
