Abstract
The disclosure relates to a process for producing ammonia, wherein a hydrocarbon mixture and steam are supplied to a primary reformer. The hydrocarbon mixture and the steam are at least partly converted to carbon monoxide and hydrogen in the primary reformer. The gas mixture from the primary reformer is directed into a secondary reformer. The secondary reformer is supplied with process air, at least comprising oxygen and nitrogen, such that unconverted hydrocarbon is converted to carbon monoxide and hydrogen. In examples, the firing output of the primary reformer is increased, the oxygen content of the process air is reduced before the process air is directed into the secondary reformer.

1-10. (canceled)
A method of configuring a plant for the production of ammonia, wherein the plant comprises:
- at least a first device for generating renewable energy from a first renewable energy source;
- a water electrolysis device;
- a hydrogen storage device;
- a converter;
- and
- wherein the method simulates the operation of the plant on the basis of historical data, wherein in carrying out the method, at least the size of the water electrolysis device, the size of the hydrogen storage device and the size of the converter are adjusted, wherein the method comprises the steps of:
- a) providing historical data on renewable energy generation;
- b) determining an average value of the energy generation from the historical data;
- c) determining the stability of the energy generation taking into account the magnitude of the change and the rate of change of the energy generation;
- d) varying the size of the water electrolysis device, the size of the hydrogen storage tank and the size of the converter and, for each plant configuration, simulating the operation of the plant to determine the total production amount and the total production cost, and
- e) identifying the minimum cost.
