Abstract
A process and a plant for producing a makeup synthesis gas (6) for the synthesis of ammonia where a hydrocarbon feedstock is reformed in a primary reformer (10) and in an autothermal reformer (14) in parallel with said primary reformer; nitrogen is furnished by an air separation unit (13), and O2-enhched air (8) produced in said air separation unit is fed to the autothermal reformer. A method for the revamping of the front-end of an ammonia plant is also disclosed.
