Abstract
A process for ammonia and methanol co-production in a plant comprising a secondary reformer section, a high-temperature CO conversion section and a low-temperature CO conversion section, arranged in series, and an ammonia synthesis section, is distinguished by the fact that the unreacted gas flow coming from a methanol synthesis section, before being fed to the low-temperature CO conversion section, is advantageously saturated with a liquid flow comprising H.sub.2 O appropriately heated by indirect heat exchange with a gaseous flow coming from the secondary reformer section.
