Abstract

See full text

The invention relates to a method and an apparatus for producing ammonia (13), in which a first hydrogen/nitrogen fraction (6) is provided at a time-varying flow rate in order to form an ammonia synthesis gas (8) which is converted to ammonia in an ammonia synthesis (A), wherein the first hydrogen/nitrogen fraction (6) is supplemented by a second hydrogen/nitrogen fraction (14) in such a way that, during normal operation, the ammonia synthesis gas (8) can always be supplied to the ammonia synthesis (A) at a flow rate which exceeds a predefined minimum value. The characterising feature here is that ammonia (10) produced in the ammonia synthesis (A) is transferred in liquid form to a storage means (Z) from which ammonia (15) is taken and split into hydrogen and nitrogen in order to obtain hydrogen and nitrogen so as to form the second hydrogen/nitrogen fraction (14).
