Abstract

A method for increasing the capacity of an ammonia plant, the plant comprising a front-end for production of a makeup syngas and a synthesis section for conversion of said make-up syngas into ammonia, the front-end comprising a primary reformer (1), a secondary reformer (2), an air compressor, a treatment section including a CO2 removal section (4), and a syngas compressor (33), the method comprising the following steps: an increase of the hydrogen that is or can be produced by the reforming section of the front-end, by means of replacement of tubes of the primary reformer and/or feeding additional oxygen to the secondary reformer; revamping of said air compressor by means of installation of new statoric and rotoric parts in such a way that the revamped compressor train is able to deliver a larger flow rate of air to the secondary reformer while keeping the same final discharge pressure; re-vamping of the CO2 removal section; revamping of the synthesis gas compressor; upgrade of the synthesis gas drying unit; revamping of the ammonia synthesis loop.
