    Abstract: A method for regulation of an ammonia plant where a purge gas (10) containing inerts is extracted from ammonia synthesis loop (SL), and where the ammonia plant is operated at a partial load by keeping the ammonia synthesis loop at a nominal high pressure, and reducing the purge rate in order to increase concentration of inerts in the ammonia synthesis loop and avoid overheating of the ammonia reactor; preferably a water electrolysis section (WE) produces a hydrogen feed (3) and an air separator produces a nitrogen feed (4); hydrogen and nitrogen are mixed to form a make up gas (5) which is reacted at a high-pressure in said ammonia synthesis loop (SL).
