Abstract
L'invention concerne un procédé de synthèse d'ammoniac comprenant la génération de gaz d'appoint dans une extrémité avant et la conversion dudit gaz d'appoint dans une boucle de synthèse d'ammoniac (5) comprenant un circulateur (6), un convertisseur (7), une section de condensation (8) et une section de séparation d'ammoniac liquide (9), comprenant : lorsque la boucle fonctionne à une charge partielle et qu'un débit de gaz d'appoint transféré de l'extrémité avant à la boucle de synthèse est réduit, la boucle est contrôlée par séparation d'un flux de gaz provenant d'une ligne d'alimentation de convertisseur (10) en un point en amont du convertisseur (7) formant ainsi un flux de dérivation (15) ; réintroduction dudit flux de dérivation au niveau du côté d'aspiration (24) du circulateur (6) ou en un point de la boucle (5) en aval de ladite section de séparation (9).
