Method and device for producing ammonia

A device for producing ammonia comprising:

• a mixing unit;
• a conversion unit connected by a first pipe to the mixing unit, with a first pressurizing member and a first heating member mounted between the conversion unit and the mixing unit, with the conversion unit outputting a critical state gas, with the conversion unit including a separator and an electrolyser;
• and
• a synthesis unit connected by a second pipe to the conversion unit, with the second pipe allowing the critical state gas to flow into the synthesis unit, with a gas outlet pipe connected to the synthesis unit, with the gas outlet pipe outputting a synthetic gas from the synthesis unit, with the second pipe including a first branch pipe, a second branch pine and a gas inlet pipe, with the separator connected to the synthesis unit by the first branch pipe, with the second branch pipe connected between the separator and the electrolyser, with the gas inlet pipe connected between the electrolyser and the synthesis unit.
