This green ammonia production system is controlled by a DCS system and includes a hydrogen production unit and a nitrogen production unit connected to a diaphragm-type hydrogen-nitrogen compressor. The hydrogen-nitrogen compressor is linked to a circulator via an intermediate cooler I. The circulator splits into two paths through an intermediate cooler II: one path connects to the reactor via a heat exchanger, while the other connects to a buffer tank, which is then connected to the reactor. The reactor is connected to an ammonia separator after passing through a heat exchanger, cooler, cold exchanger, and ammonia condenser. The ammonia outlet of the ammonia separator connects to an ammonia storage unit, and the reaction gas outlet connects to the circulator via a cold exchanger. Inside the reactor, there is a superheated steam generator connected to a waste heat power generation and distribution unit. The inlet of the superheated steam generator is also connected to a water treatment unit. The waste heat power generation and distribution unit is connected to a new energy grid, providing electricity for the system. This product features low production costs and high safety, enables remote control of production, and holds promising application prospects.
